Racket Vibration Insert with Extraction Orifice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration reduction devices for sports rackets, such as anti-vibrators, are either complex and not adaptable to existing racket designs, affect ball rebound, or are difficult to remove and reposition, failing to provide effective vibration absorption and balance adjustment.
Innovation Solution
The development of insert devices with variable dimensions, made from flexible materials like carbon fibre or glass fibre, which fit into the racket holes below the striking face, featuring a cylindrical section with a conical extension and a bored orifice for easy extraction, allowing for adjustable balance and torsion enhancement without impacting ball rebound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If anti-vibrators are introduced into orifices in the striking face, then vibrations are reduced, but ball rebound is severely hampered and becomes irregular
Solution Approach 1:
The invention extracts the anti-vibration function from the striking face by relocating the dampening element to the handle area. The resin cylinder is positioned in the lower portion of the handle rather than in holes on the striking face, thereby eliminating interference with ball rebound while maintaining vibration reduction through the same material damping properties
Solution Approach 2:
The resin cylinder acts as an intermediary element positioned in the handle that absorbs vibrations generated during ball impact. By placing this damping mediator in the handle rather than the striking face, the system achieves vibration control without directly interfering with the ball-racket interaction
2Object-affected harmful factors
If anti-vibrators are introduced into orifices, then vibrations are reduced, but the devices are complicated to remove and reposition
Solution Approach 1:
The invention segments the racket into functional zones, placing the vibration-dampening resin cylinder in the handle portion separate from the striking face. This segmentation allows the anti-vibrator to be positioned independently in the handle holes, making it easier to remove and reposition without affecting the integrity of the striking face structure
Solution Approach 2:
The invention creates a dynamic configuration where the resin cylinder can be easily inserted into and removed from the handle holes. The cylindrical shape and positioning in the handle rather than the striking face allow players to adjust or remove the device without permanent installation, providing operational flexibility
3Object-affected harmful factors
If complex impact absorber structures are used, then shockwaves are absorbed effectively, but the structures cannot be adapted to existing racket designs
Solution Approach 1:
The invention creates a universal solution by using a simple resin cylinder that can be adapted to any racket with holes in the handle. This universal dampening element works across different racket designs, materials, and hole configurations, eliminating the need for complex structure-specific absorption systems
Solution Approach 2:
The invention changes the parameter of placement location from the striking face to the handle area. This parameter change allows the same simple cylindrical resin structure to be universally applied to existing rackets without requiring complex adaptations, as long as the racket has holes in the handle portion
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
These devices effectively absorb vibrations, allow for adjustable balance and torsion, and can be easily inserted or removed, enhancing player comfort, control, and power by modifying the racket's centre of gravity and balance without hindering ball rebound.
Implementation Method 1
The insert will be fitted into the hole in the bat below the striking face... with the main characteristic that the inserts are fitted into the holes of the bat itself. In this way, the vibrations of play itself are successfully absorbed
