Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beach and pickleball rackets face issues with durability and striking resistance due to the use of foam materials that fatigue and age quickly, leading to reduced service life and impaired hitting performance.
Innovation Solution
A composite fabric is produced through a twice-compositing process involving pre-treatment, hot pressing, and cooling of fiberglass and resin layers to create a durable and lightweight rough board for racket surfaces, enhancing striking resistance and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If foam materials are used as the covering material of racket faceplate, then the racket achieves lightweight design, but the striking resistance and service life are reduced due to fatigue and aging
Solution Approach 1:
The patent applies composite materials by combining fiberglass fabric, resin, and metal mesh layers to create a faceplate that achieves both lightweight design and high striking resistance. The fiberglass provides strength while the metal mesh reinforcement prevents deformation, resolving the contradiction between light weight and durability.
Solution Approach 2:
The patent implements local quality by adding metal mesh reinforcement specifically in high-stress areas of the faceplate. This localized strengthening provides enhanced striking resistance where needed while maintaining overall lightweight design, avoiding the need to increase the weight of the entire racket.
2Weight of moving object
If foam materials are used as the covering material of racket faceplate, then the racket achieves lightweight design, but the service life is limited due to aging damage
Solution Approach 1:
The patent uses composite materials consisting of fiberglass fabric impregnated with resin and reinforced with metal mesh. This composite structure eliminates the aging problems of foam materials while maintaining lightweight properties, significantly extending the service life of the racket.
Solution Approach 2:
The patent replaces the short-lived foam material with a durable composite structure designed to last throughout the racket's entire service life, eliminating the need for replacement and ensuring long-term reliability.
3Weight of moving object
If foam materials are used as the covering material of racket faceplate, then the racket achieves lightweight design, but the flexibility and hitting effect are affected after a period of use
Solution Approach 1:
The patent employs composite materials with fiberglass providing flexibility and resin providing structural stability. The metal mesh reinforcement maintains the faceplate's shape and hitting characteristics over time, ensuring consistent performance while keeping the racket lightweight.
Solution Approach 2:
The patent applies metal mesh reinforcement strategically to maintain structural stability in critical areas while preserving flexibility in other regions, ensuring the racket maintains its hitting effect and flexibility throughout its service life.

AI summary
A rough board compositing process, comprising the following steps: S1: pre-treating raw materials; S2: pre-cutting materials; S3: performing first hot pressing fusion; S4: obtaining a faceplate layer core material after the hot pressing fusion; S5: cutting a demoulding cloth, a third resin layer, a supporting structure layer and a release film material; S6: stacking the materials one by one; S7: performing second hot pressing fusion to obtain a composite board; and S8: tearing off the demoulding cloth from the composite board to obtain a final product, a composite rough board. By the described process, a lightweight and durable composite rough board is obtained. The composite rough board is capable of effectively increasing striking resistance and prolonging service life. The composite fabric is suitable for covering beach rackets or pickleball rackets to improve durability and striking resistance.
