Vehicle Inverter Attachment Structure with Nested Battery Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle apparatus attaching structures allow for the incorrect detachment of inverter and auxiliary battery, where either unit can be detached prematurely, leading to improper procedure usage.
Innovation Solution
The structure ensures secure detachment by designing the auxiliary battery attachment unit to cover the inverter attachment unit's attachment portion, preventing the inverter from being detached until the auxiliary battery is removed first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inverter and auxiliary battery are attached separately with independent attachment portions, then both units can be detached individually, but the risk of incorrect detachment procedure increases
Solution Approach 1:
The auxiliary battery attachment unit is nested within the inverter attachment unit, with the auxiliary battery attachment portion positioned inside the inverter attachment portion. This nesting structure ensures that the auxiliary battery must be detached first before the inverter can be removed, preventing incorrect detachment procedures while maintaining operational ease.
2Reliability
If the auxiliary battery attachment unit covers the inverter attachment portion, then incorrect detachment is prevented, but the structural complexity increases
Solution Approach 1:
The attachment structures for the inverter and auxiliary battery are merged into a single integrated attachment unit. The auxiliary battery attachment portion is combined with the inverter attachment portion, creating a unified structure that simplifies the overall design while ensuring correct detachment sequence through the covering relationship.

AI summary
An inverter attachment unit (150) including an inverter (40) is attached to a vehicle body (130). In addition, an auxiliary battery attachment unit (160) including an auxiliary battery (60) is attached to the vehicle body (130) so that the auxiliary battery attachment unit (160) may be adjacent to the inverter attachment unit (150). When the auxiliary battery attachment unit (160) is attached to the vehicle body (130), attachment portions (181a, 181b) by which the inverter attachment unit (150) is attached to the vehicle body (130) are covered with the auxiliary battery attachment unit (160).
