Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent modules are mounted in the same position to form functional integration, then integration requirements are met, but installation and maintenance become inconvenient and the electrical control box becomes large and heavy
Solution Approach 1:
The electrical control box is segmented into a base plate and multiple detachable mounting plates (first mounting plate, second mounting plate, etc.). Each mounting plate can be independently installed and removed, allowing individual module maintenance while maintaining overall integration. The base plate includes detachable mounting structures that enable separate access to different electrical components without disassembling the entire control box.
2Adaptability or versatility
If independent modules are mounted in the same position to form functional integration, then integration requirements are met, but the electrical control box size and weight increase
Solution Approach 1:
Multiple mounting plates and electrical components are merged onto a single integrated base plate structure. The base plate serves as a common mounting surface for multiple independent modules, consolidating what would otherwise require separate mounting structures. This merging reduces overall space requirements and decreases the total weight of the electrical control box while maintaining functional independence of each module.
3Ease of repair
If detachable heat dissipation base plates are used, then maintenance convenience is improved, but structural complexity increases
Solution Approach 1:
The base plate is designed as a universal mounting structure that serves multiple functions: structural support, heat dissipation, and modular component mounting. The detachable mounting plates can be universally applied to different electrical components (DCDC converter, DCAC converter, etc.), reducing the need for component-specific mounting structures. This multi-functionality simplifies the overall structure while enabling easy maintenance access.
