Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional isolation boards are used, then the structure is simple, but the fixing force for electrical connection pieces is insufficient, leading to potential dislodging under vibration
Solution Approach 1:
The isolation board is segmented into multiple functional regions: supporting portions for vertical support, first limiting portions for height direction confinement, and second limiting portions for lateral movement restriction. This segmentation allows each region to perform its specific function efficiently, achieving reliable fixing through distributed structural elements rather than a monolithic complex design
Solution Approach 2:
The invention adds vertical dimension elements (first limiting portions extending in height direction) to the traditional planar isolation board structure. This dimensional enhancement creates intervals that three-dimensionally constrain the electrical connection pieces, preventing dislodging under vibration while maintaining overall structural simplicity
2Reliability
If conventional isolation boards with fixing structures are used, then some fixing force is provided, but assembling space must be reserved, reducing fixing reliability
Solution Approach 1:
The isolation board is pre-designed with integrated supporting and limiting portions that create ready-to-use intervals for receiving electrical connection pieces. These structures are prepared in advance during board manufacturing, eliminating the need for additional assembling space or complex assembly operations, as the fixing structures are already in their final configuration
Solution Approach 2:
The supporting portions and limiting portions are merged into a single integrated isolation board structure rather than separate components. This consolidation eliminates the need for additional assembling space that would be required for separate fixing structures, while maintaining both assembling convenience and high fixing reliability through the unified design
3Reliability
If conventional isolation board assemblies are used, then the structure is functional, but the overall volume is large, reducing space utilization in battery modules
Solution Approach 1:
By introducing vertical limiting portions that extend in the height direction, the invention confines electrical connection pieces within three-dimensional intervals rather than requiring lateral expansion. This dimensional approach achieves reliable fixing while minimizing the overall footprint and volume of the isolation board assembly, optimizing space utilization in battery modules
Solution Approach 2:
The isolation board features localized limiting portions positioned precisely where needed to constrain electrical connection pieces. Rather than uniformly increasing the size of the entire board, the limiting structures are concentrated in specific local regions, achieving high fixing reliability with minimal volume increase

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures reliable assembly and prevents electrical connection pieces from falling off, significantly reducing the volume and weight of the isolation board assembly, improving space utilization and cost-effectiveness in battery modules.
Implementation Method 1
Each elastic latching member and the corresponding first limiting portion are spaced apart from each other in the height direction, and each elastic latching member is latched to the first end portion of the corresponding electrical connection piece

AI summary
The present invention provides an isolation board assembly and a battery module, the isolation board assembly comprises an isolation board and electrical connection pieces. The isolation board comprises: a plurality of supporting portions; a plurality of first limiting portions, each first limiting portion and the corresponding supporting portion form an interval. Each electrical connection piece comprises a first end portion and a second end portion. The first end portion is received in the interval, clamped and fixed by the first limiting portion and the supporting portion, and the second end portion extends out of the supporting portion. The assembly manner is simple and fast, which improves the assembling efficiency. Because the first end portion is supported on the supporting portion, the second end portion extends out of the supporting portion, it makes the dimension of the isolation board is small, thereby decreasing the volume and weight of the isolation board.
