Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electric capacitors are incorporated into a holder with leads connected to a wiring substrate, then the capacitor unit achieves functional integration, but the complexity of positioning and aligning the leads increases significantly
Solution Approach 1:
The holder is designed with pre-formed guide holes at predetermined positions that correspond to the terminal parts of the capacitor main bodies. This preliminary arrangement of guide holes eliminates the need for complex lead positioning work during assembly, as the guide holes automatically guide the leads to their correct positions on the wiring substrate.
Solution Approach 2:
The holder acts as an intermediary component between the capacitor main bodies and the wiring substrate. It provides guide holes that mediate the connection process, ensuring proper alignment of leads with terminal parts without requiring complex manual positioning or adjustment during assembly.
2Stability of the object's composition
If connection members and circuit substrates are fixed within capacitor units, then structural stability is improved, but the complexity of securing these components increases
Solution Approach 1:
The holder integrates multiple functions: it accommodates capacitor main bodies, provides guide holes for lead alignment, and serves as a mounting structure for connection members and circuit substrates. By merging these functions into a single component, the overall structure achieves stability without requiring additional separate securing mechanisms.
Solution Approach 2:
The holder is designed as a multi-functional component that simultaneously provides mechanical support for capacitor main bodies, guidance for lead connections, and mounting structure for connection members and circuit substrates. This universality reduces the number of separate components needed and simplifies the overall securing process.
3Manufacturing precision
If capacitor main bodies are accommodated with terminal parts in the same orientation, then connection alignment is simplified, but the flexibility of accommodation arrangements is reduced
Solution Approach 1:
The holder is designed with asymmetric guide hole arrangements that correspond to the specific orientation requirements of the capacitor main bodies. The guide holes are positioned and oriented in a non-symmetric pattern that ensures proper alignment of terminal parts while still accommodating the capacitors in a standardized configuration.
Solution Approach 2:
The holder provides localized guide structures at specific positions where capacitor main bodies are accommodated. Each guide hole is precisely positioned and oriented to match the terminal part orientation requirements of the capacitor main bodies, ensuring high alignment precision at the local level while maintaining overall structural flexibility.
