Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal elastic member is used in the pumping device, then the elastic properties and reciprocating capability are provided, but rusting occurs leading to contamination and inefficient recycling
Solution Approach 1:
The patent changes the material parameter of the elastic member from metal to plastic, specifically using a plastic material that does not rust. This material substitution eliminates the harmful rusting contamination while maintaining the necessary elastic properties through proper plastic material selection and design.
Solution Approach 2:
The patent employs composite material structures where plastic elastic members are integrated with plastic housing components. This composite approach allows the entire pumping device to be made from non-rusting materials, eliminating contamination while maintaining functional integrity through the composite plastic construction.
2Ease of manufacture
If metal and plastic parts are used together in the pumping device, then manufacturing cost is reduced, but separation is required for recycling reducing recycling efficiency
Solution Approach 1:
The patent merges all components into a single plastic material system, eliminating the need to separate metal and plastic parts during recycling. The elastic member, housing, and other components are all made from plastic, allowing the entire device to be recycled as one unit, significantly improving recycling efficiency.
Solution Approach 2:
The patent changes the material composition parameter from a metal-plastic composite to a single plastic material system. This parameter change simplifies the recycling process by eliminating separation requirements while maintaining manufacturing cost effectiveness through the use of inexpensive plastic materials.
3Object-affected harmful factors
If a plastic elastic member is used to avoid rusting, then contamination is prevented, but elasticity reduction occurs due to yielding and deformation from long-time pressure
Solution Approach 1:
The patent changes the material parameters by selecting specific plastic materials with appropriate elastic modulus, tensile strength, and fatigue resistance properties. These parameter optimizations allow the plastic elastic member to maintain stable elasticity over long periods without yielding or deforming, while still providing contamination-free operation.
Solution Approach 2:
The patent uses composite plastic materials that combine the benefits of rust resistance with enhanced mechanical properties. The composite plastic construction provides both contamination prevention and long-term elasticity stability through the use of high-performance plastic materials designed for durable elastic operation.
4Reliability
If the elastic member is made larger to maintain elasticity, then desired elastic properties are obtained, but device size increases
Solution Approach 1:
The patent optimizes the geometric parameters and material properties of the plastic elastic member to achieve desired elastic properties with minimal size. By carefully selecting plastic material parameters and optimizing the member's dimensions, the patent maintains elasticity while minimizing the volume increase that would result from using a larger elastic member.
