Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a wire and a refrigerant pipe are disposed around high-voltage devices with large diameters, then temperature management function is achieved, but vehicle space is suppressed
Solution Approach 1:
The wire harness and refrigerant pipe are merged into a single integrated assembly where the wire harness is wrapped around the refrigerant pipe. This combination allows both components to occupy the same spatial envelope, effectively reducing the total volume required for temperature management while maintaining both electrical connectivity and thermal cooling functions.
Solution Approach 2:
The wire harness is nested around the refrigerant pipe in a spiral or wrapped configuration, similar to a nested doll structure. This nesting arrangement allows the wire harness to utilize the circumferential space around the pipe, maximizing space utilization and minimizing the overall footprint of the temperature management system.
2Power
If high-voltage wires with large diameter are used, then high voltage transmission capability is achieved, but mounting space increases
Solution Approach 1:
Multiple high-voltage wires are combined into a bundled wire harness that is then wrapped around the refrigerant pipe. This merging of individual wires into a compact harness structure reduces the overall mounting space required while maintaining the high voltage transmission capability through the bundled configuration.
3Temperature
If cooling hose with large diameter is used, then temperature management capability is achieved, but vehicle space is suppressed
Solution Approach 1:
The cooling hose (refrigerant pipe) is merged with the wire harness into a single integrated assembly. By wrapping the wire harness around the cooling hose, the system maintains adequate cooling capacity through the pipe's diameter while reducing the overall vehicle space required by eliminating separate mounting requirements for both components.
