Racket Shock-Absorbing Device with Hard Seat and Soft Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rackets lack a shock-absorbing device to mitigate the transfer of counter shock forces to the wrist or arm during ball striking, leading to potential sport injuries and instability in holding the racket due to unabsorbed shock waves and unadjustable weight distribution.
Innovation Solution
A racket with a shock-absorbing device comprising a lower hard seat member and an upper soft pad member, featuring protrusions and buckle slots, which are arranged between grommets to absorb and dampen shock waves, enhancing operation safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional racket with single grommets and strings is used, then the racket structure is simple and easy to manufacture, but shock waves from ball contact are fully transferred to the wrist and arm causing sport injuries
Solution Approach 1:
The shock-absorbing device is divided into multiple functional components: a lower hard seat member with protrusions and recesses, and an upper soft pad member with buckle slots. This segmentation allows each component to perform specific shock-absorbing functions while maintaining overall structural integrity and reducing injury risk
Solution Approach 2:
The device combines hard and soft materials in a composite structure. The lower hard seat member provides structural support and initial shock resistance, while the upper soft pad member provides cushioning and shock damping. This composite approach enhances shock absorption capability without excessive complexity
2Speed
If high string tension is used to improve ball striking performance, then the racket responds better to ball contact, but the counter shock force increases proportionally transferring more shock to the wrist and arm
Solution Approach 1:
The shock-absorbing device acts as an intermediary element between the strings and the racket frame. It mediates the force transmission by absorbing and damping counter shock forces before they reach the user's wrist and arm, allowing high string tension to be used without proportional increase in harmful shock forces
3Adaptability or versatility
If the racket frame periphery weight is fixed, then the manufacturing process is simplified, but the racket cannot be adjusted to meet different user requirements
Solution Approach 1:
The shock-absorbing device incorporates adjustable elements that allow the racket's weight distribution to be modified according to user preferences. This dynamic adjustability enhances adaptability to different user requirements while the modular design keeps manufacturing complexity manageable
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shock-absorbing device effectively reduces sport-related injuries and improves racket hold stability by absorbing and damping shock forces, while allowing adjustable weight distribution.
Implementation Method 1
the upper soft pad member is disposed on a top end of the lower hard seat member... capable of bearing shock waves of a counter shock force generated when a string of a racket face and a racket is struck so as to reduce the shock wave being transferred to a wrist or an arm of a user
