Inverter Case Structure for Collision-Resistant Connector Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inverter structures are complicated and heavy, and the safety of the low-voltage connector connecting portion is compromised during vehicle collisions due to insufficient structural strength.
Innovation Solution
The low-voltage connector connecting portion is reinforced by overlapping it with a structurally strong flange portion and incorporating ribs on the outer wall, while being positioned adjacent to a corner of the case to disperse impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If another structure is further attached to the inverter to buffer a collision, then collision safety is improved, but device complexity increases and weight increases
Solution Approach 1:
The patent combines the collision buffering function with the existing flange portion structure. The flange portion is designed to overlap with the connector connecting portion, creating an integrated structural element that provides both attachment functionality and collision protection without requiring separate buffering components.
Solution Approach 2:
The flange portion serves multiple functions: it acts as an attachment portion for mounting the inverter, provides structural support, and simultaneously serves as a collision buffering structure when it overlaps with the connector connecting portion. This multi-functionality eliminates the need for dedicated collision protection components.
2Reliability
If another structure is further attached to the inverter to buffer a collision, then collision safety is improved, but weight increases
Solution Approach 1:
The collision buffering capability is merged into the existing flange portion structure. By designing the flange portion to overlap with the connector connecting portion, the patent creates a multi-functional structural element that provides collision protection without adding separate components and associated weight.
Solution Approach 2:
The flange portion is designed to perform multiple functions including structural support, attachment, and collision buffering. This multi-functionality allows the inverter to achieve collision safety without requiring additional dedicated components that would increase overall weight.
3Reliability
If the connector connecting portion is made stronger to prevent damage during collision, then collision safety is improved, but device complexity increases
Solution Approach 1:
The patent merges the strengthening function with the existing flange portion structure. The overlapping arrangement between the flange portion and connector connecting portion creates a reinforced structural configuration that enhances connector strength without requiring separate strengthening components or complex additional structures.

AI summary
An inverter includes a case, and the case includes an upper case and a lower case attached to a bottom surface side of the upper case. The upper case includes a flange portion constituting an attachment portion of the lower case, and a connector connecting portion to which a connector is connected. The connector connecting portion includes an outer wall portion that forms an outer wall of the connector connecting portion. At least a part of the flange portion and at least a part of the outer wall portion are disposed so as to overlap each other in a direction in which the connector connecting portion and the structure face each other.
