Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat sink is arranged in the housing opposite the rear side face made of metallic material, then heat dissipation is optimized, but the housing material must be modified from plastic to metal
Solution Approach 1:
The patent merges the phase connection terminal and heat sink into a single integrated conductive component. This eliminates the need to modify the housing material while achieving efficient heat dissipation, as the integrated terminal serves both electrical connection and thermal management functions simultaneously.
Solution Approach 2:
The phase connection terminal serves dual purposes: electrical connection and heat dissipation. By making the terminal itself the heat sink through its conductive properties and geometric configuration, the system uses existing components for thermal management without requiring additional housing material changes.
2Temperature
If conductive plates are used to dissipate thermal energy by conduction along electrical phase conductors, then thermal energy dissipation is improved, but assembly operations become tedious and meticulous
Solution Approach 1:
The patent integrates the heat sink functionality directly into the phase connection terminal structure, eliminating the need for separate conductive plates. This integration removes multiple assembly steps and meticulous positioning requirements while maintaining effective thermal conduction through the unified conductive path.
Solution Approach 2:
The patent extracts the heat dissipation function from separate conductive plates and incorporates it into the phase connection terminal itself. This extraction simplifies the overall structure by removing unnecessary intermediate components and their associated assembly complexities.
3Ease of operation
If multiple separate components are used for phase current line and heat sink, then assembly flexibility is maintained, but the number of electrical junctions increases
Solution Approach 1:
The patent combines the phase connection terminal and heat sink into a single integrated conductive component, reducing the number of electrical junctions and connection points. This integration maintains assembly flexibility through modular design while eliminating unnecessary junctions between separate components.
