Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional elastomers are used to manufacture watch or jewelry components, then mechanical properties and UV resistance are achieved, but cost increases and environmental management becomes difficult
Solution Approach 1:
The patent changes the compositional parameters by limiting elastomer content to maximum 50% and incorporating at least 30% thermoplastic polymer, transforming the material from traditional high-elastomer formulations to a balanced composite that maintains performance while improving environmental manageability and cost-effectiveness
Solution Approach 2:
The patent creates a composite material system combining elastomer with thermoplastic polymer, where the elastomer provides mechanical properties and UV resistance while the thermoplastic polymer improves processability and environmental management, achieving a synergistic effect that resolves the contradiction between reliability and ease of manufacture
2Strength
If large quantity of elastomer is used in component manufacture, then mechanical properties are maintained, but cost increases and environmental standards compliance becomes difficult
Solution Approach 1:
The patent changes the quantity parameter by capping elastomer content at 50% maximum and introducing thermoplastic polymer as a complementary material, reducing the total quantity of elastomer required while maintaining tensile strength through the composite structure and optimized formulation
3Strength
If traditional elastomeric materials are used, then mechanical properties are achieved, but cost increases
Solution Approach 1:
The patent develops a cost-effective composite material by combining elastomer (maximum 50%) with thermoplastic polymer (minimum 30%), where the thermoplastic component reduces material cost while the elastomer maintains tensile strength, achieving a balance between performance and manufacturing cost
Solution Approach 2:
The patent optimizes the compositional parameters to reduce cost by limiting expensive elastomer content to 50% maximum and incorporating cheaper thermoplastic polymers, while maintaining the minimum 30% thermoplastic content to ensure adequate mechanical properties at lower cost
