Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple suspension wires are exposed to air for electrical conduction, then electrical conductivity is maintained, but oxidation occurs resulting in short lifespan
Solution Approach 1:
A protective layer is introduced as an intermediary between the conductive wire and the surrounding environment. This protective layer prevents direct contact between the conductive material and oxygen/moisture in the air, thereby eliminating oxidation while maintaining electrical conductivity through the layered structure.
Solution Approach 2:
The suspension wire structure employs a composite design with multiple materials: an inner conductive core for electrical conduction, a middle protective layer for oxidation resistance, and an outer conductive layer for maintaining electrical continuity. This composite structure resolves the contradiction by combining materials with different functional properties.
2Reliability
If a protective layer is added to prevent oxidation, then lifespan is extended, but electrical conductivity may be compromised
Solution Approach 1:
The patent uses a multi-layer composite structure where the inner layer provides oxidation protection and the outer conductive layer ensures electrical continuity. This composite design allows both protection and conductivity to coexist without compromising either function.
Solution Approach 2:
Different layers of the suspension wire are assigned different material properties: the inner protective layer has oxidation-resistant properties while the outer layer has high electrical conductivity. This local differentiation of material qualities allows each layer to optimize its specific function while working together as a unified structure.
