How a table tennis racket concept tries to level up your game

Most sports equipment haven’t changed their overall design in decades. Yes, materials and parts have been improved, but the general shape has remained the same, especially when they need to conform to certain standards. That’s mostly true for equipment used in actual competition, but there’s definitely plenty of room for innovation when it comes to learning and training tools. Of course, you can’t simply change a standard and well-tested design willy-nilly, but you can definitely make changes here and there to improve a player’s experience and comfort. The table tennis racket, for example, hasn’t exactly changed for over a decade, so this design concept tries to breathe new life into the sport by introducing not only flexibility but also a bit of intelligence to the traditional paddle.

Designer: Shubhangi Chuhadia

The table tennis racket is probably one of the more sustainable pieces of sports equipment even today. It’s mostly made of wood, though laminated for longevity, and rubber pads on one or both sides of the paddle. Unfortunately, this design has also made the paddle less flexible for customization after assembly. Professional players will have to choose the weight and materials to match their playing style before the racket is fully assembled.

Nimbus is a concept design that changes the core makeup of the tablet tennis racket in order to give it more flexible and ergonomic properties. By moving away from wood, the design is able to introduce a new element into the handle, a nook that can be fitted with different kinds of tabs depending on the need of the player. In this manner, a single paddle can be adapted to different use cases without having to wastefully manufacture a new paddle for every instance.

Those removable tabs, for example, can provide the desired weight to match the player’s grip or playing style. It can also be a tracker that can gather the player’s metrics and send the data to a paired phone for analysis. This way, the paddle itself can be an effective training tool without having to attach awkward sensors to the racket or the player’s body.

The redesigned handle is also designed for better comfort, especially for extra-long games. Although traditional table tennis rackets also keep that detail in mind, their conventional design includes sharp edges that cut into the skin after prolonged use. The Nimbus concept will hardly become a standard adopted by international sports organizations, but it shows how even the simplest changes can have significant benefits, especially when given the freedom to think outside the box.

AI-generated Hìtëkw Tennis Racquet – YD x KeyShot Inspiration Hub Design of the Month #2

The second-ever YD x KeyShot Inspiration Hub Design of the Month goes to the Hìtëkw, a rather interesting-looking tennis racquet with an even more interesting back story. Designed using a combination of AI-based tools as well as generative design, the Hìtëkw boasts of a futuristic visual aesthetic that’s never been seen before… and that isn’t all. The redesigned racquet is lighter and stronger too, as a result of this AI-powered makeover!

Designer: All Design Lab

All Design Lab experimented with using OpenAI’s Dall·E2 to generate concept directions for the racquet’s design, only to realize that almost the AI could only work on a dataset of existing images; and nobody had ever made a racquet like the Hìtëkw before, which made it difficult for the AI to really think outside the box. This became the starting point for All Design Lab’s creative brief, which was to completely redesign the racquet’s silhouette itself.

To create new racquet archetypes, the All Design Lab team relied on new CAD tools. The designers created their rough form in Gravity Sketch, a VR-based 3D program that lets you sketch and sculpt in virtual reality, before taking the product to a generative algorithm to optimize the racquet’s unique frame for strength and reliability. The result was the Hìtëkw, a racquet that’s stronger and lighter than its competitors, with a distinct visual edge thanks to its organic, 3D-printed generative metal design.

“Rackets have become more lightweight and durable through new materials and advanced manufacturing techniques”, the All Design Lab team mentions. “Yet the potential is still there to envision an even lighter and stronger racket that takes advantage of new design techniques, specifically, advanced CAD processes such as generative design tools.”

If you don’t know what the YD x KeyShot Inspiration Hub is, it’s best to think of it as the ultimate destination to find the most inspirational design work, as well as to have your own work featured so that it can be seen by a global audience of thousands of designers and creatives… an ever-expanding encyclopedia of good design and great rendering, if you will.

The hub helps fulfill YD and KeyShot’s broad goal of recognizing exemplary work from a distance and helping amplify it without having to rely on an algorithm, unlike with portfolio sites and social media. It relies on YD’s two-decade-long year history of curating great ideas, concepts, and case studies and ties it to KeyShot’s powerful position as the design industry’s most powerful and preferred rendering software.

Edgy Lamborghini Sneaker Concept celebrates the legacy of the Italian marque on their 60th anniversary

In the past 60 years of its existence, Lamborghini’s made everything from tractors to supercars, and even the odd luxury yacht… but “what if Lamborghini made high-end performance footwear?” asks designer Hussain Almossawi. Designed as a tribute to the automotive icon’s 60-year rich legacy as well as an interesting ‘what-if’ hypothetical, these Lamborghini Performance Sneakers rather wonderfully encapsulate the company’s raging-bull design aesthetic, with an edgy piece of footwear that boasts great surface treatment and some absolutely jaw-dropping glowing details around the midsole and outsole.

Designer: Hussain Almossawi

Envisioned in two rather aptly named colorways – Redline Phantom, and Glacier Ignition, the sneakers come with a split-toe design and enough Lamborghini iconography to make these recognizable from a mile off. You’ve even got neon lights on the side in white and red, like the car’s headlights and taillights, along with air vents that instantly help viewers create that visual bridge between automobiles and footwear. It also helps that Almossawi’s approach to shoe design looks so radically different, that you’d almost never confuse it with your ordinary pair of kicks. After all, a Lamborghini is far from ordinary, right?

The shoe’s chaotic design ties in beautifully with some of Lamborghini’s more exclusive cars (the Sián and Terzo Millennio come to mind). The shoe’s multi-panel design features the use of regular and suede leather for that premium touch, against a technical fabric with a hexagonal design for that wild, sporty touch, and even a little carbon-fiber thrown in for that signature automotive callback. Glossy plastic elements like the one on the toe tip add that rugged appeal to the shoes, while those glowing elements on the side and base make the shoe look undeniably futuristic and like they’re made for speed.

The shoes are layered with Lamborghini iconography, including the company’s logo on a metal plate on the shoe’s tongue, the brand name glowing on the back, a subtle Italy flag on the front, along with the horned logo commemorating the Italian marque’s 60th anniversary.

“To bring this shoe design to life, a detailed 3D model was created using cutting-edge CGI technology,” Almossawi tells Yanko Design. “The process involved intricate digital sculpting and precise material simulation to ensure that the shoe design accurately reflected the textures and details of the envisioned materials, including the smooth leather and suede leather.​​​​​​​”

A designer and bestselling author, Hussain Almossawi is based out of Brooklyn, New York, and has consulted with companies such as Apple, Nike, Adidas, Ford Motors, and other world-known brands. Click here to view the process behind creating these sneaker concepts.

Snøhetta transforms alpine ski tower in Austria using modern + reinvented Tyrolean design

Tucking away in the impassive mountains of Alpbachtal, Austria, and perched 2030 meters above sea level is a panorama room and tower built by Snøhetta. The project was commissioned by the Ski Juwel Alpbachtal Wildschönau ski resort to celebrate its tenth anniversary. They commissioned Snøhetta to replace an old, out-of-style ski lift with a new chairlift.

Designer: Snøhetta

Snøhetta drew inspiration from the beautiful snow-capped surroundings and alpine building traditions for constructing the tower. Called, ‘Top of Alpbachtal’, the tower is located near the Wiedersberger Horn peak, and the Hornbahn 2000 cable car mountain station. It was designed to function as a landmark that uplifts and elevates the mountain experience of skiers and visitors as well. The imposing tower is connected to a narrow volume that rises thirteen meters above the ground and is clad in locally-crafted shingles.

A panoramic viewing room has been inserted into the tower, and it provides stunning views to not only skiers but summer hikers, snowshoe walkers, and ski tourers. The concrete base of the tower holds a lift control room, which is followed by a public lounge. The viewing room is located on the first floor of the structure. This format was inspired by the traditional parlors of Tyrolean farmhouses, wherein the lower sections would have a wooden wall paneling finish and an open roof similar to agricultural buildings.

The lounge in the tower has been designed in a modern Tyrolean style. It functions as an informal seating area for skiers and visitors to meet up and relax in. The room is marked by wooden seating platforms, giving visitors their own space to unwind in after a long day of skiing. The lounge is sheltered and protected from the wind, and visitors aren’t required to consume anything if they don’t feel like it. Massive panoramic windows provide surreal views of the stunning alpine landscape. The particular structural style was picked as it was suitable for both winters and summers. The peak of the viewing tower provides visitors with 360-degree views of the exquisite alpine scenery. The shingles on the valley station allow the structure to harmoniously merge with the landscape.

YD x KeyShot Inspiration Hub Design of the Month #1 – Samsung Action Camera Concept

Bagging the first Design of the Month spot is the Samsung Action Camera concept from designer Isaac Lee. I can’t begin to describe the kind of love I have for transparent objects, not just for their design appeal, but for the kind of effort that goes into rendering them. Making a product transparent means needing to detail out interior components, and adding screws, supports, and parting lines to the insides of plastic or glass parts. It’s a lot of effort for a seemingly low pay-off, but it’s the kind of effort I absolutely don’t mind rewarding!

Designer: Isaac Lee

The Samsung Action Camera, although it looks large, is quite a small contraption no larger than a GoPro or any other action camera. It comes with one wide-angle lens, along with a few other features like a record button, control knob, digital viewfinder, and an LCD screen on the top like the one seen on retro-style cameras. On the side, you’ve got two USB-C ports, and a 3.5mm aux in for an external microphone.

If you don’t know what the YD x KeyShot Inspiration Hub is, it’s best to think of it as the ultimate destination to find the most inspirational design work, as well as to have your own work featured, so it can be seen by a global audience of thousands of designers and creatives… an ever-expanding encyclopedia of good design and great rendering, if you will.

Wilson reveals 3D printed ‘Airless’ Basketball with a stunning see-through hexagonal mesh design

Keeping your eye on the ball never got easier!

Using a format and technique similar to those airless car tire concepts we’ve seen before, Wilson’s latest airless basketball employs a similar see-through 3D-printed mesh to create a ball that bounces just like a basketball… but looks like nothing any basketball you’ve ever seen before. The design was unveiled at the NBA Slam Dunk Contest, with Houston Rockets forward KJ Martin taking the ball for a literal spin. Quite to everyone’s amazement, the Airless Basketball prototype responds to stimulus exactly like the standard inflated basketball. It’s easy to grip, has a surprisingly responsive bounce, and defies convention with its unique aesthetic!

Designer: Wilson Sporting Goods Co.

Created as an experimental prototype by Wilson Sporting Goods Co.’s R&D (Basketball) division, the Airless Basketball prototype is a stunning piece of design and engineering that looks, weighs, and bounces just like a basketball, but fundamentally rethinks the ball’s physical structure and underlying physics. The ball employs a 3D hexagonal mesh structure that’s highly elastic, enabling it to bounce just like a pressurized ball. However, its airless nature means it never needs maintaining or refilling, unlike standard basketballs that lose their bounce when they deflate mildly.

What’s so impressive about the Airless Basketball, apart from its jaw-dropping aesthetic, is that it completely rewrites the rulebook. Most basketballs have their signature bounce because they’re filled with pressurized air. Reduce the pressure and the ball just flops onto the floor with a dissatisfying thud. Wilson’s redesign goes against that notion, thanks to its unique structure and elastomeric material. Arrived through multiple design iterations and rigorous testing at the NBA test facility in Ada, Ohio, the ball cleverly balances tradition and innovation, with a futuristic mesh design that still feels relatively familiar in the hand, having the same weight as a regulation basketball and even the familiar seams for players to rest their fingers in.

The ball’s brilliant redesign comes from Wilson’s R&D division, led by Dr. Nadine Lippa, Kevin Krysiak, and a team of designers and engineers. As they worked on ‘reinventing the basketball’, Lippa knew pretty much instantly that such a complex structure could only be achieved through additive 3D printing. Having gone through multiple iterations, the team arrived at the design we see today, featuring the hexagonal mesh that not only gives the ball its signature bounce but also creates a grippy texture, much like the dotted pattern found on existing balls.

The team partnered with EOS, a 3D-printing solutions company, to help build the functional prototype. The ball started out as a pit of white powder, coming to life as the powder was melted into shape using a laser in a process commonly known as SLS or selective laser sintering. After the print was complete, the team dusted off the excess powder, before ‘sealing’ the design into its shape using yet another machine. Black dye was then injected into the model in a third and final process, giving us the final, finished ball. It’s unclear how long the entire process took, although 3D printing is known to be a relatively slower process. The trade-off, however, is a ball that requires much less upkeep and doesn’t ever need pumping or refilling.

Although the ball was just previewed for merely a handful of seconds at the Slam Dunk Contest, we’re yet to see it be used in an entire match. A lot of factors remain undetermined, like the ball’s lifespan, resistance to damage, how well players can grip it, whether objects can get stuck inside the ball’s mesh, how it reacts to spin, and what its overall aerodynamics are.

Wilson isn’t planning on manufacturing these for retail or for professional games. This prototype is the result of a long-term experiment to push the boundaries of innovation at the company and test out new materials and structures. Basketballers can be an incredibly superstitious bunch, and notoriously resistant to major change, so don’t expect to see this in any NBA games soon… although maybe it could debut as an add-on upgrade in NBA Live! EA Sports, make it happen!

Compact indoor rower lets you have an effective and accessible workout at home

Being able to exercise at home has become a necessity for many people, especially for those without easy access to gyms or gym equipment. In modern homes, it’s difficult to find space for more than one or two home fitness machines, so it’s important to choose one that can pack the most efficient workout into a compact size. Rowing is an exercise that engages 85% of muscles, and this portable rowing device lets you complete both cardio and strength training workouts at home without surrendering space to a bulky and noisy metal monster.

Rowing activates nine muscle groups, giving an almost total workout. ROWBRO also comes with a built-in pull-up bar and the handle can be used on its own for resistance strength training. This means that you only need one machine for just about all your exercising needs.

Designers: Florian Kaufmann & Diego Kaufmann

Typical rowers are large, menacing, and bulky machines that permanently take up residence in your house. Depending on the type of resistance mechanism used, they can also be noisy. Ever heard the sloshing of a machine with water resistance or the whirring of a machine with air resistance? Forget about enjoying a quiet workout while your family or neighbors enjoy sleeping in.

ROWBRO is an innovative solution that you can easily set up and store away every time you use it. You can carry it around the house to change your workout location for variety or maybe even bring it with you to another house while on an extended stay. And with its magnetic resistance mechanism, it is virtually silent, letting you sweat it out in peace without bothering anyone else.

The secret to ROWBRO is its ingenious design that gets away from the bulky frame. For stability, you will need to have a steady doorway to set up the pull-up bar that serves as the machine’s mount. Alternatively, you can also get the wall mount add-on to set it up against a wall if a door frame isn’t available. Once the ROWBRO is secured, you attach the guide rail and unfold it on the floor, and then place the wheeled seat on it. Once all that is done, you can simply sit down, put your feet on the machine, and start rowing your way to fitness.

ROWBRO also comes with a pull-up bar so you can work your biceps and much more.

ROWBRO is made for rowing novices and pros—the rower offers three levels of resistance for optimal rowing control—low, medium, and high.

Despite its seemingly simple design, the ROWBRO is a capable machine that offers multiple levels of resistance for different people. There’s also an accompanying app that you can install on any smartphone or tablet to measure and keep track of your workouts, with a premium membership in the works that will offer live instructions and fun games. You also don’t have to worry about the wheels ruining your floor, as they are the same type of floor-friendly wheels used for inline skates. They work best on hard floors but will also function well on any carpet that you could roll an office chair over.

For only $328 early bird, ROWBRO is a fraction of what other indoor rowers cost, giving you an efficient workout you can have at home without having to sacrifice any of your precious floor space forever.

Unique bone-conducting wearable allows swimmers to listen to music and podcasts underwater

Swimming remains one of the most top-tier exercises, providing full-body cardio, resistance training, and the ability to stay cool while exercising all in one shot. However, it has one big disadvantage – you can’t listen to music while swimming. “One of the issues that swimmers face during workouts is that swimming sometimes can get monotonous. Over time it becomes quite boring to swim from one side of the pool to the other,” say the designers behind SONR, the world’s first swimming-focused audio device. Designed to be the swimming equivalent of popping AirPods in while hitting the gym, the SONR Music is a unique wearable designed to help swimmers listen to music, podcasts, and instructions while underwater. The puck-shaped device slides underneath your cap or goggles, sitting firmly against the back of your skull and uses bone-conducting technology to deliver audio to you. It’s designed to make you ‘hear’ audio by delivering vibrations to your inner ear via the bones in your skull. That means your ears remain free to either stay open or to wear earplugs while swimming.

Designer: SONR Inc.

SONR’s journey started with the eponymously named flagship device, which focused on allowing swimmers to listen to their trainers/instructors while swimming. Paired with a walkie-talkie that delivered the trainer’s speech in real-time, SONR allowed the swimmer to hear their coach even while moving through water. The SONR Music takes its predecessor’s technology and builds on it by adding Bluetooth functionality to the device. Pair it with your phone and the SONR Music lets you listen to tunes or podcasts while you swim. Create a playlist and you could be in the water for hours without getting bored… or have your workout/performance affected by intrusive, negative thoughts that could decrease your motivation and focus.

The SONR Music’s one-size-fits-all design makes it perfect for virtually anyone. It slips right under your cap or the strap of your goggles, and in just minutes, you’ll forget it’s even there. The device plays audio by delivering vibrations directly to your inner ear by circumventing the eardrum altogether. You can hear music while also listening to noises around you, or wear earplugs to hear your music/podcasts better. The device is designed to be water-resistant up to 5ATM, and here’s the kicker – it works just as well on land too, allowing you to use it while cycling, trekking, and exercising. Conversely, you could also use it while surfing or paddleboarding.

The SONR Music works with locally-stored files too, offering up the ability to swim in larger pools without having your Bluetooth connection stutter or falter. Athletes can directly store audio files (music, podcasts, motivational audio) onto the SONR Music and have them play back while swimming. The device has a battery life of 8 hours, and a built-in memory of 8Gb. Each SONR Music ships with a goggle clip, USB charging cable, and swimming earplugs.

Nike Mercurial Lite Superlock shin guards have special spikes overlaid to safely pierce sock fiber and lock in place

Modern-day footballers require slim, durable, and impact-diffusing shin guards to succeed on the pitch. The comfortable cushioning, durable shell, and lightweight design make the Nike Mercurial Lite Shin Guards the go-to contoured sleeve you can get to secure your shins and play unhindered.

Adding more substance to Nike’s already fascinating shin guards, a designer has fashioned the shin guards with geometric columns and webbing to replace the traditionally used foam. This makes the Nike Mercurial Lite Superlock shin guards more flexible and thicker in the middle. For a seamless fit, the guards are tapered toward the edges.

Designer: Matthew Blunt

The Lite Superlock is designed to minimize distraction on the field. This is made possible by the very unique spikes overlaid on the shin guards that safely pierce the sock fiber to lock the guards in place, while the fine curvature (thick to thin transition around the leg) ensures a comfortable fit.

The seamless fit means you enjoy durability and comfort without slowing your game down. Since the entire surface area of the Nike Mercurial Lite Superlock shin guards is covered with small spikes to hold it in place attaching firmly to the socks, they can be worn without the need for straps or sleeves.

Like you’d expect from any Mercurial shin guard from Nike, Matthew Blunt-designed Nike Mercurial shin guards also have a low profile and are meant for left/right fit. Even though the design is far from seeing the light of day, it does have the potential to find Nike’s design boards, especially for its spiked design. Everything looks good to me, but I am not very sure how the ball/foot hitting the shin will affect the spikes on the shin guard: will they hold shape and grip even on continuous impact?

This seemingly simple arm patch lets you know how much water to drink and when

It isn’t just our planet that’s mostly made up of water. Our bodies, too, have large quantities of water and require a regular intake of fluids to keep them functioning properly. We all know this for a fact, yet few of us take the advice to heart. Those with more active lifestyles are often more conscious of this and hydrate more regularly, but they might not always know the most optimal strategy for the time and amount of water or other fluids to drink. Without sophisticated equipment to monitor your body’s fluid output, you might not know how much to take in. That’s the kind of information that this sensor offers, and it involves nothing more than just slapping a patch on your arm before your run or exercise.

Designer: Nix

The common advice is to drink eight glasses or two liters of water a day, which is fine for most cases and individuals. When you live a more active lifestyle, though, especially if you work out often, when and how you hydrate involves more than that simple metric. Making it a bit more complicated is that different people have different hydration needs and rates of dehydration depending on their activity.

Rather than leaving that important health factor up to guesswork or generic figures, the Nix Hydration Biosensor uses science and technology to actually give you a better picture of your body’s hydration state. It’s almost similar to how our smartwatches constantly keep track of our heart rate, except that it uses a different biomarker and part of your body. This simple device sticks to your skin and tracks your fluid and electrolyte loss through the sweat you produce during activities.

There is already equipment that can measure that data, but these are often bulky machines that can only be used inside labs and involve connecting multiple sensors to your body. This Hydration Biosensor, in contrast, whittles it down to just a hexagon-shaped pod that clips onto a sweat patch that you stick to your arm. Because of the sensor’s lightweight construction and the absence of any wires, the Hydration Biosensor won’t get in the way of any kind of workout or activity you might engage in.

Similar to a smartwatch, the sensor sends its data to a companion device, usually a smartphone, which does the heavy work of analyzing that data to notify you when it’s time to drink up and how much. This might sound like micromanaging, but it’s the kind of efficiency that many athletes live by in order to get the best out of their workout as well as their recovery. At the very least, it will get people more aware of just how important hydration is to our well-being, especially when you start to notice how you get dehydrated more often than not.
