About this project
What is CURVSTAR?
CURVSTAR is a sleek, innovative and unique tennis racket that is changing the way a tennis racket looks. The ergonomic CURVSTAR racket not only improves your game but also keeps your wrist and forearm in a more natural position. The patented and International Tennis Federation approved racket was designed for players of all ages and skill levels. Former pro German tennis player Thomas Emmrich was a major contributor in the final design of this unique racket, and he just won the European Doubles Championship with one of our final prototypes.
Our Innovative Concept:
Since its official inception in 1874, the tennis racket has always had a straight grip with a circular or oval head attached atop. After 140 years we thought it was about time the tennis racket got a makeover.
Using the Parabolic Ski analogy described in our video, as well as looking at other ergonomic shapes from chairs, keyboards etc. we adjusted the straight grip of the racket and made it curved. This innovation came from not only years of experience as a competitive tennis player, but after years of research and collaboration with engineers and health professionals.
As the image above shows, a traditional tennis racket causes the wrist to bend in an unnatural and uncomfortable position. This type of strain on the wrist and elbow causes injury, and we knew there had to be a solution to this. From this notion, we developed a racket and grip that better aligns with the natural shape of your hand.
The offset racket head and curved grip resulted in an evolution in racket design. Awarded with a certified design patent and approved for league play, we believe this new curved shape will become an industry standard. In addition to providing better wrist and elbow alignment, the offset racket head provides game advantages, including: creation of more spin and slice, easier volleys, faster serves and better control on lower shots.
Development of the Curvstar Racket
1. At the start of this journey, we worked with engineers and sports medicine professionals to study the body and how it moved with a tennis racket. We specifically focused on the movement of the shoulder, elbow, and wrist. Creating drawings and renderings, we were able to understand the body mechanics and formulate early ideas of what the racket should look like.
2. From here we were able to create initial sketches and designs of the racket. Working off several variations we were able to get a clear enough picture to start creating 3D models.
3. Working within modeling programs we played with dozens of variations and design combinations. Some of the designs that didn’t make the cut included warped frames, triangular heads, and longer handles.
4. Then after years of research, designing, modeling, and testing we finally landed on a design. We created a racket that was mathematically meant to fit the curvature of a person’s palm. With our final design in hand, we produced a very limited number of prototypes and tested the heck out of it. We aimed at launching the business under a different brand but unfortunately never had the funding to go into full production. Now we further enhanced the branding and design with the bright and vibrant neon colors and are launching on Kickstarter to finally get this innovation off the ground.
How is it Better Than a Traditional Racket?
Why We Need Your Help?
We’ve done all the hard work developing the racket, working with engineers, choosing the best materials, and making sure it’s everything we could have imagined. Now we need your help to cross the finish line! Your funds will go towards:
Please help us get this labor of love off the factory floor and to the masses! Every little bit helps!
Production / Fulfillment Plan:
The initial $50,000 will allow us to complete the first round of production on the adult racket. When we raise $150,000, we can go into production of a kids racket mold, allowing us to also offer the ergonomic racket to our up and coming youth!
When you back our campaign you will get exclusive access to photo shoots of the racket, updates on where we are in the process, a look at the people behind this, and more. Also "Like" us on Facebook and follow us on Twitter for more behind-the-scenes access. Don’t miss out on the chance to be a part of the future of tennis!
Risks and challenges
Over the years of fine-tuning the racket design, we have been able to minimize risks. We have gone through pain staking measures to test the racket and put it under real-life stress and developed several prototypes. The result is a racket that is not only 100% functional, but was approved by the International Tennis Federation for professional league play. Not to mention one of our prototypes was just used to win the European Doubles Championship by former pro German tennis player Thomas Emmrich.
We have secured one mold to produce the rackets and potential risks could be busy production lines or out of stock fabrics if the demand exceeds our expectations. However, we have estimated those times and included them to the delivery schedule.
