Solution Overview
Problem
Existing battery pack and module assembly technologies face challenges in cost-effective assembly and manufacturing, often requiring multiple types of parts, which complicates scaling and increases costs.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of battery module members are used to assemble battery module assembly, then the assembly can accommodate different configurations and requirements, but the number of different parts increases, complicating assembly and manufacturing processes
Solution Approach 1:
The battery module member is designed with a universal structure that can serve multiple functions and positions within the battery module assembly. The frame structure with specifically positioned holes can function as side members, end members, or intermediate members depending on how they are arranged and connected, eliminating the need for different specialized parts for different positions.
Solution Approach 2:
The battery module member is divided into functional segments through the strategic placement of holes (first holes for through-fastening, second holes for interference fit) that can be selectively used depending on the assembly requirements. This segmentation allows a single part type to be configured for different assembly needs without requiring multiple specialized part variants.
2Adaptability or versatility
If multiple types of battery module members are used, then different assembly configurations are possible, but the manufacturing cost increases due to higher part variety
Solution Approach 1:
By designing a universal battery module member that can function in multiple positions and configurations, the manufacturing cost is reduced through economies of scale. A single part type can be mass-produced rather than multiple specialized parts, while still achieving the required assembly configurations through different arrangements and connection methods of the same component.
Solution Approach 2:
The same battery module member can be adapted to different assembly configurations by changing assembly parameters such as the selection and combination of connection methods (through-fastening vs. interference fit) and the arrangement pattern, rather than changing the physical parameters of the parts themselves.
3Productivity
If through-fastening holes are used to connect battery module members, then the connection is simple and fast, but the structural strength may be insufficient compared to interference fit
Solution Approach 1:
The invention merges two connection methods (through-fastening and interference fit) into a single battery module member design. Different connection methods can be selectively applied to different holes or different assembly locations, combining the speed advantage of through-fastening with the strength advantage of interference fit to achieve both high productivity and strong connections.
Solution Approach 2:
Different regions or holes of the battery module member are designed with different connection capabilities (first holes for through-fastening, second holes for interference fit). This local differentiation allows the optimal connection method to be applied to each specific location based on the required strength and assembly considerations, rather than using a single uniform connection method throughout.
