Integrated Racket Encapsulation to Prevent Wrap and Handle Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rackets prepared by traditional methods suffer from high wastage due to separation of the wrapping surface and handle sleeve during use, leading to inefficiencies in production and assembly.
Innovation Solution
An integrally encapsulated racket production process involving injection molding of a plastic adhesive tape and handle sleeve, with a honeycomb board substrate, ensuring the wrapping surface and racket body are integrated, and a smooth cladding layer for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wrapping surface and handle sleeve are manually attached to the racket body, then the production process is simple and flexible, but the wrapping surface and handle sleeve are prone to separation during use, leading to high wastage rate
Solution Approach 1:
The patent combines the wrapping surface and handle sleeve into a single integrated component that is injection-molded as one piece onto the racket body. This merging eliminates the separate attachment steps and prevents separation during use, resolving the contradiction between manufacturing simplicity and attachment stability.
Solution Approach 2:
The patent uses composite material structure where the wrapping surface is made of silica gel material integrated with the racket body through injection molding. This composite approach ensures strong bonding while maintaining the simplicity of the production process.
2Device complexity
If the wrapping surface is manually stuck onto the racket body, then the production process requires minimal equipment, but the manual process reduces production efficiency and increases labor intensity
Solution Approach 1:
The patent replaces the manual mechanical sticking process with an injection molding system. The injection molding machine automatically forms the wrapping surface and handle sleeve as an integrated component, significantly improving production efficiency while reducing labor intensity.
Solution Approach 2:
The patent changes the production method from manual low-temperature adhesive application to automated high-temperature injection molding. This parameter change enables mass production with higher efficiency while maintaining equipment simplicity through the use of standard injection molding machinery.
3Adaptability or versatility
If adhesive tape is manually wound around the handle to form a handle sleeve, then the handle customization is flexible, but the adhesive tape is prone to separation and reduces product reliability
Solution Approach 1:
The patent merges the handle sleeve formation process with the main racket body production through integrated injection molding. The handle sleeve is formed as part of the same molding process, ensuring it cannot separate from the racket body while still allowing for customization through mold design.
4Ease of repair
If separate components are used for wrapping surface and handle sleeve, then the production process allows for independent replacement and repair, but the separation during use leads to high wastage rate
Solution Approach 1:
The patent combines the wrapping surface and handle sleeve into a single integrated component that is injection-molded onto the racket body. This prevents separation during use and eliminates the need for separate repairs, thereby reducing racket wastage rate while maintaining functionality.
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
Enhances the durability and hand feel of the racket, reduces noise, prevents bulging, and increases production efficiency by integrating the wrapping surface and handle sleeve, while improving the racket's overall assembly process.
Implementation Method 1
placing the racket body with the edge sealed in S2 in an injection mold, wrapping, by the injection mold, the racket body with the edge of the racket body being exposed, and injecting the injection mold by an injection molding machine, so that a plastic covered edge is injection molded at the edge of the racket body
Implementation Method 2
a plastic adhesive tape is disposed at a connecting part between the wrapping surface and the racket body, the plastic adhesive tape is attached to an edge of the racket body
Implementation Method 3
selecting a honeycomb board as a substrate and cutting the honeycomb board into a racket body
Implementation Method 4
attaching a smooth cladding layer to the finished racket, where the smooth cladding layer wraps the racket body, and then the racket surface of the finished racket is protected by the smooth cladding layer
