Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust structure with case, molding member, and cover is integrated to protect wires and enhance sealing, then sealing performance and wire protection are improved, but device complexity increases
Solution Approach 1:
The case, molding member, and cover are integrated into a unified guide member assembly that combines structural support, wire protection, and sealing functions into a single coordinated structure, reducing the number of separate components while maintaining comprehensive protection
Solution Approach 2:
The guide member structure serves multiple functions simultaneously: the case provides structural support and positioning, the molding member protects wires and enhances sealing, and the cover completes the protective enclosure, creating a multi-functional integrated component that addresses several requirements at once
2Reliability
If a guide member with case, molding member, and cover is integrated to protect wires, then wire protection is improved, but ease of assembly deteriorates
Solution Approach 1:
The guide member is divided into separable components (case, molding member, and cover) that can be assembled and disassembled independently, allowing for easier maintenance and wire replacement while maintaining comprehensive protection when assembled
Solution Approach 2:
The molding member is nested within the case and covered by the cover, creating a hierarchical structure where components fit within each other, which simplifies the assembly process by reducing the number of fastening operations required while providing layered protection for the wires
3Power
If thermoelectric modules are disposed on one surface of the duct with integrated guide member, then power generation performance is improved, but device complexity increases
Solution Approach 1:
The guide member is integrated with the chamber structure, merging the wire guidance function with the housing structure, which reduces the number of separate components while maintaining all necessary functions for power generation and wire management
Solution Approach 2:
The chamber serves multiple functions: it houses the thermoelectric conversion part, provides structural support, and integrates the guide member for wire management, creating a multi-functional component that improves power generation performance without proportionally increasing complexity
