Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a dedicated storage structure with enhanced rigidity is provided in the lower vehicle body, then the electrical equipment can be securely installed, but the design flexibility is hindered and cost increases
Solution Approach 1:
The spare tire housing is repurposed to serve dual functions: storing the spare tire and housing the electrical equipment (charger). This eliminates the need for a dedicated storage structure, maintaining rigidity through the existing housing while preserving design flexibility by utilizing an already-present structural component.
Solution Approach 2:
The patent combines the spare tire storage function and electrical equipment housing function into a single integrated space. The brackets and support structures serve both to mount the electrical equipment and to reinforce the housing structure, reducing the need for separate dedicated components.
2Strength
If a dedicated body structure with enhanced rigidity is employed, then the electrical equipment can be securely installed, but cost increases
Solution Approach 1:
The existing spare tire housing structure is utilized for dual purposes, eliminating the need to manufacture a separate dedicated storage structure. This reduces manufacturing costs while maintaining the required rigidity through the existing housing and added brackets.
Solution Approach 2:
The support brackets are designed to serve multiple functions: mounting the electrical equipment, reinforcing the housing structure, and providing attachment points for cooling system components. This consolidation reduces the total number of parts and manufacturing steps.
3Temperature
If a cooling duct is provided to utilize air stream, then the charger can be cooled, but the vehicle body structure becomes complicated
Solution Approach 1:
The cooling air passage is integrated with the existing spare tire housing structure and bracket system. The brackets serve both as mounting structures and as structural components of the cooling air pathway, eliminating the need for separate dedicated cooling ducts and reducing overall structural complexity.
Solution Approach 2:
The housing and bracket structures perform multiple functions: structural support, equipment mounting, and cooling air flow pathways. This multi-functionality eliminates the need for separate dedicated cooling ducts, simplifying the overall vehicle body structure.
4Temperature
If a cooling duct is provided, then the charger can be cooled, but the vehicle body structure becomes complicated and cooling effectiveness is insufficient
Solution Approach 1:
The cooling system is integrated with the mounting bracket structure. The brackets form part of the cooling air passage structure, and the blower is positioned to work directly with the finned heat sinks. This integration improves cooling effectiveness while avoiding the complexity of separate dedicated cooling ducts.
Solution Approach 2:
The patent introduces a blower as an active cooling intermediary device that forces air through the finned heat sinks. This active cooling mechanism, combined with the integrated bracket structure, provides sufficient cooling effectiveness without requiring complex passive cooling ducts.
