Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If epoxy resin composite materials are used for paddle structure, then strength and toughness are improved, but recyclability deteriorates
Solution Approach 1:
The patent changes the material parameter from epoxy resin to polypropylene, which has different chemical properties that enable recyclability while maintaining mechanical strength through optimized honeycomb structure and fiber fabric integration
Solution Approach 2:
The patent uses composite materials consisting of polypropylene honeycomb structure combined with fiber fabric (carbon fiber, glass fiber, hemp fiber, flax fiber, aramid fiber, or basalt fiber) to achieve both strength requirements and recyclability
2Strength
If epoxy resin composite materials are used for paddle structure, then rebound performance is improved, but environmental impact worsens
Solution Approach 1:
The patent changes the material from non-recyclable epoxy resin to recyclable polypropylene, reducing environmental impact through crushable recycling while maintaining rebound performance through optimized structural design
Solution Approach 2:
The patent converts the previously harmful disposal method (burial or incineration of epoxy resin paddles) into a beneficial recycling process by using crushable polypropylene material that can be remanufactured into new items
3Ease of manufacture
If polypropylene material is used for paddle structure, then recyclability is improved, but structural strength may deteriorate
Solution Approach 1:
The patent combines polypropylene honeycomb structure with fiber fabric layers to create a composite material system that maintains structural strength while preserving the recyclability of the polypropylene base material
Solution Approach 2:
The patent uses a honeycomb porous structure made of polypropylene that provides both mechanical strength through its geometric configuration and recyclability through material uniformity, allowing the entire structure to be crushed and remanufactured

AI summary
A pickleball paddle includes a first padding, two second paddings, an edge strip, and a grip. The first padding is a honeycomb structure made of polypropylene. The second paddings are bonded to two opposite surfaces of the first padding, and the second paddings each have a polypropylene layer and a fiber fabric bonded to the polypropylene layer. The edge strip is connected to the edge of the first padding and the edges of the second paddings, and the edge strip is made of a material including polypropylene. The grip is connected to the edge strip, and the grip is made of a material including polypropylene. Thus, the pickleball paddle of the present invention is easy to recycle and can reduce harm to the environment. Additionally, the present invention further includes a method of recycling the aforesaid pickleball paddle.
