Racket Rough Panel With Embedded Logo Layer for Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for displaying logos on pickleball and beach ball rackets result in wear and tear due to their placement on the outer surface, which is prone to damage during use.
Innovation Solution
A rough panel with a logo layer is embedded between a carbon cloth layer and a rough layer, made through die pressing, using materials like carbon fiber and glass fiber for the logo layer, which is integrated into the racket structure to prevent wear and enhance spin speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the logo is printed or pasted on the outer surface of the racket, then the logo is easily applied and displayed, but the logo is vulnerable to wear and tear during use
Solution Approach 1:
The logo layer is nested between the carbon cloth layer and the rough layer, embedding the logo within the multi-layer structure rather than placing it on the outer surface. This nesting approach protects the logo from wear and tear while maintaining its visibility and integration within the racket panel.
Solution Approach 2:
The invention uses a composite structure with multiple layers including carbon cloth layer, logo layer, and rough layer, all bonded together through die pressing. This composite material approach provides both durability and logo protection while maintaining the functional properties of each layer.
2Illumination intensity
If the logo layer is placed on the outer surface, then the logo is prominently displayed, but the logo layer lacks protection and strength
Solution Approach 1:
The logo layer is positioned between the carbon cloth layer and the rough layer, allowing it to be protected by the stronger surrounding layers while still being visible through the semi-transparent carbon cloth layer. This nesting provides both protection and visibility.
Solution Approach 2:
Each layer in the composite structure has specific local properties: the carbon cloth layer provides strength and visibility, the logo layer provides branding, and the rough layer provides texture and ball contact properties. This local quality differentiation allows the logo to be protected while remaining visible.
3Reliability
If the logo layer is embedded between carbon cloth layer and rough layer through die pressing, then the logo is protected and the panel integrity is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The invention combines multiple functions into a single integrated structure: the logo layer is embedded within the composite panel during the die pressing process, eliminating the need for separate logo application steps. This merging of logo application with panel manufacturing simplifies the overall process while providing logo protection.
Solution Approach 2:
The die pressing process simultaneously bonds the carbon cloth layer, logo layer, and rough layer into a unified composite structure. This composite material approach allows the logo to be embedded and protected while the entire panel is manufactured in one integrated process, reducing overall complexity.
4Strength
If the rough layer is made by die pressing with release cloth, then the panel strength is improved, but the process requires additional steps and materials
Solution Approach 1:
The release cloth is placed on the carbon cloth layer before die pressing to prevent adhesion during the high-pressure bonding process. This preliminary action ensures that the layers bond properly to each other while releasing from the mold, enabling the strength-building die pressing process without permanent mold adhesion issues.
Solution Approach 2:
The release cloth acts as an intermediary between the die press mold and the carbon cloth layer, allowing the high-pressure bonding process to proceed without the mold material permanently adhering to the panel. This intermediary enables the strength-improving die pressing while facilitating easy removal of the finished panel.

AI summary
The utility model discloses a rough panel with a logo layer and a racket. The rough panel with the logo layer comprises: a carbon cloth layer; and a rough layer arranged on the carbon cloth layer; wherein a logo layer is arranged between the carbon cloth layer and the rough layer, the rough panel is made by die pressing, and the logo layer is embedded in the carbon cloth layer and/or the rough layer. The arrangement of the logo layer between the carbon cloth layer and the rough layer effectively prevents the wear and tear of the logo layer, allowing it to be displayed more effectively.
