Elastic Tennis Racquet Grip Shell with Velcro Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tennis racket handle devices are inflexible and cumbersome, making it difficult to change grip positions and requiring mechanical preparation, which limits their universal usability and causes operational restrictions.
Innovation Solution
A grip shell with elastic ends and a fastening system using a Velcro strap allows for a non-positive connection that can adapt to different grip geometries, enabling secure and flexible positioning without damaging the racket handle, and can be easily connected and disconnected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a grip shell with fixed contour is firmly connected to the racket handle, then the racquet holding is improved and twisting is reduced, but the device cannot adapt to changes in gripping hand position and requires mechanical preparation of the racquet
Solution Approach 1:
The grip shell is designed with elastic ends that can deform and adapt to different gripping positions dynamically. The elastic material allows the shell to maintain contact and stability while accommodating changes in hand position, transitioning from a static to a dynamic structure that responds to user interaction.
Solution Approach 2:
The elastic properties of the grip shell ends allow for parameter changes in shape and position. The material can stretch and compress to adapt to different grip geometries, enabling the same device to work with various hand positions without requiring mechanical modifications to the racquet handle.
2Reliability
If the grip shell is firmly fixed to the racket handle, then secure holding is achieved, but the device becomes cumbersome to connect and disconnect and requires damaging machining of the handle
Solution Approach 1:
The fastening system is divided into separate components: the grip shell with elastic ends and the Velcro fastener strips. This segmentation allows the connection to be made and broken easily by simply fastening or unfastening the Velcro, without requiring permanent attachment or damaging the racquet handle.
Solution Approach 2:
The traditional mechanical fastening systems (screws, clamps, grooves) are replaced with a Velcro fastener system. This substitution eliminates the need for complex mechanical assembly and disassembly, and removes the requirement for machining the handle, while maintaining secure connection through the elastic grip shell.
3Strength
If the grip shell is made rigid for stable positioning, then power transmission is improved, but the device cannot adapt to different grip geometries and damages the racquet handle during installation
Solution Approach 1:
The grip shell exhibits different local qualities: the main body is rigid to provide stable positioning and effective power transmission, while the ends are elastic to adapt to different grip geometries. This local differentiation allows the device to maintain structural integrity for power transmission while accommodating variations in hand position and handle shape.
