Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional metal studs (aluminum) are used, then traction performance is improved, but cost increases and price fluctuation occurs
Solution Approach 1:
The patent changes the material parameter from metal to polymer, specifically using reinforced plastics like polyvinyl chloride (PVC) or polyethylene (PE) to maintain mechanical properties while reducing cost and eliminating price fluctuation associated with metal materials
Solution Approach 2:
The patent employs composite materials by reinforcing polymer studs with fibers or other additives to achieve the necessary mechanical strength and durability for traction performance, combining the advantages of polymer (low cost) with reinforcement (strength)
2Strength
If metal body studs are used, then structural strength is improved, but noise generation increases
Solution Approach 1:
The patent uses polymer materials that are inherently quieter than metal while providing sufficient service life for the application, accepting that the stud body may degrade over time but eliminating the noise problem associated with metal
Solution Approach 2:
The patent uses fiber-reinforced polymer composites to achieve structural strength comparable to metal while maintaining the noise-reduction benefits of polymer materials
3Reliability
If metal body studs are used, then durability is improved, but environmental pollution increases due to material ejection
Solution Approach 1:
The patent adopts biodegradable polymer materials that are designed to degrade after a certain service period, eliminating the environmental pollution problem caused by metal particle ejection and accumulation in ecosystems
Solution Approach 2:
The patent changes the material composition from non-biodegradable metal to biodegradable polymers, fundamentally altering the environmental behavior of the stud material from persistent pollution to controlled degradation
