Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide rail accuracy is increased to achieve precise connector fitting, then manufacturing complexity and cost increase, but fitting precision is improved
Solution Approach 1:
The connector is designed with self-fitting capability through asymmetric structure and guide pins that automatically align and position the connector during insertion, eliminating the need for high-precision guide rails. The connector itself performs the positioning function that would otherwise require precision manufacturing of the guide rail system.
Solution Approach 2:
Guide pins are introduced as intermediary elements between the guide rail and the connector. These guide pins provide the necessary alignment and positioning guidance, allowing the use of lower-precision guide rails while still achieving accurate connector fitting. The guide pins act as a mediator that compensates for the reduced precision of the guide rail system.
2Ease of operation
If manual connection of cables and couplers is required, then ease of operation is improved for maintenance, but device complexity and maintenance time increase
Solution Approach 1:
The cable connection structure is merged with the connector assembly, integrating the cable routing and connection functions into the same structural unit. This integration eliminates separate manual connection steps for cables and connectors, reducing overall device complexity while maintaining ease of maintenance through the unified removable module design.
Solution Approach 2:
The connector assembly is designed as a universal module that handles multiple functions including electrical connection, cable routing, and mechanical positioning. This multi-functional design reduces the number of separate components and manual operations required, simplifying the overall system while maintaining operational ease.
3Productivity
If CPU density is increased in limited area, then productivity is improved, but heat generation increases requiring more efficient cooling
Solution Approach 1:
The cooling system is segmented into modular cooling units that can be independently configured and positioned. Each cooling unit targets specific high-heat-generation areas, allowing efficient heat dissipation from densely packed CPUs. The segmentation enables scalable cooling capacity that matches the CPU density configuration.
