Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in improving the positioning accuracy of conductive members and cooling performance in stacked configurations, such as bus bars in electrical machines and battery units, due to lack of gaps between stacked components.
Innovation Solution
An element module with conductive members and a spacer member is used, where the spacer is placed between adjacent conductive members to create a gap, enhancing positioning accuracy and cooling performance by allowing better heat dissipation and reducing contact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a plurality of plate-shaped bus bars are stacked on each other without a gap, then the compactness of the stacked body is improved, but the cooling performance of the entire stacked body deteriorates
Solution Approach 1:
The patent divides the continuous stacked structure into segmented sections by introducing spacer members between adjacent conductive members. This segmentation creates gaps that allow cooling media to flow through the stacked body, improving cooling performance while maintaining compact overall structure.
Solution Approach 2:
The spacer member acts as an intermediary element inserted between adjacent conductive members (bus bars). This intermediary component creates the necessary gaps for cooling without requiring changes to the conductive members themselves, enabling improved heat dissipation while maintaining structural integrity.
2Temperature
If a plurality of bus bars are arranged at predetermined intervals in a cell stacking direction, then the cooling performance is improved, but the positioning accuracy of the bus bars deteriorates
Solution Approach 1:
The spacer member is designed with positioning protrusions that engage with corresponding positioning recesses on the conductive members. This self-positioning mechanism ensures accurate alignment and positioning of bus bars without requiring external positioning fixtures or complex assembly procedures, maintaining high manufacturing precision while enabling effective cooling gaps.
