Hybrid Vehicle Integrated Package Module Case Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing case structure for integrated package modules in hybrid vehicles requires excessive labor for assembly due to large-sized components, increases vehicle weight and manufacturing costs, and poses risks of assembly errors with safety covers being assembled incorrectly, potentially stopping vehicle operation.
Innovation Solution
A case structure with a first and second front case divided into sections, featuring a receiving groove and a safety cover with a pin mechanism to prevent incorrect assembly, along with a lightweight, rectangular plate-shaped mounting member that reduces assembly labor and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the front case is formed as a large-sized body, then the case can provide sufficient structural support and sealing, but a plurality of fastening bolts need to be screwed to multiple portions, requiring large amounts of labor and decreasing productivity
Solution Approach 1:
The front case is divided into a first front case and a second front case that can be assembled separately and then coupled together. This segmentation allows each section to be fastened with fewer bolts, reducing assembly labor while maintaining the overall structural support capability of the complete front case assembly
2Stability of the object's composition
If a heavy mounting member is used to support the upper portion of the rear case, then the integrated package module can be stably mounted on the vehicle body, but vehicle weight and manufacturing costs increase
Solution Approach 1:
The mounting member is designed as a rectangular plate-shaped component that optimizes the ratio of material usage to structural strength. This composite design provides sufficient mounting stability while minimizing weight compared to traditional heavy mounting members
