Pickleball Paddle Texture Durability via Direct Coating Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pickleball paddles fail to meet both aesthetic and durability requirements due to complex production processes and texture issues that lead to peeling off, affecting both control and appearance.
Innovation Solution
A pickleball paddle design featuring a substrate layer with a fiber face sheet, where a semi-gloss or full-gloss oil-based coating is applied directly to form a texture on the outer surface, optionally covering a pattern layer for enhanced aesthetics without compromising structural integrity or durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin film with texture is attached to the fiber face sheet, then the friction of the paddle surface is improved, but the production process becomes complex and the texture is easy to peel off
Solution Approach 1:
The patent merges the texture formation and coating application into a single integrated process. The texture is formed directly on the coating layer itself rather than being a separate resin film attached to the surface. This eliminates the need for separate resin film attachment steps while ensuring the texture becomes an integral part of the coating structure, preventing peeling.
Solution Approach 2:
The patent extracts the texture formation step from the separate resin film application process. Instead of attaching a pre-formed textured resin film, the texture is generated in-situ during the coating application process through direct pressing of the coating material, simplifying the overall production process.
2Reliability
If a coating with particles is sprayed on the fiber face sheet, then the surface friction is improved, but the coating is prone to peeling off after use
Solution Approach 1:
The patent replaces durable but complex resin films with a simpler, more economical coating material that achieves the same functional effect. The coating material used is a water-based or solvent-based paint containing particulate matter, which is simpler and more cost-effective than resin films while providing equivalent or superior performance.
Solution Approach 2:
The patent uses a composite coating material consisting of a binder (water-based or solvent-based paint) and particulate matter. This composite structure provides both the adhesive properties needed for durable attachment to the fiber face sheet and the surface roughness needed for increased friction, eliminating the peeling problem of previous coatings.
3Shape
If a pattern layer is disposed on the fiber face sheet for beautification, then the aesthetic appearance is improved, but the coating connection is weakened and peeling occurs
Solution Approach 1:
The patent resolves the conflict between aesthetics and adhesion by adding a temporal dimension to the layer structure. The pattern layer is applied first as a base layer, then the functional coating is applied over it. This layering approach in the vertical dimension allows both the aesthetic pattern and the functional coating to coexist, with the coating providing adhesion to the fiber face sheet through its binder while the pattern layer provides aesthetics underneath.
