Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If known housings for battery modules are used, then the battery module is accommodated, but the installation space required is large and the weight is high
Solution Approach 1:
The housing is divided into multiple separate housing parts (front housing part, rear housing part, and at least one central housing part) that can be assembled together. This segmentation allows for optimized space utilization and reduced material usage compared to a single monolithic housing structure, thereby reducing both installation space and weight.
Solution Approach 2:
The housing parts are designed with universal applicability to accommodate battery modules with different geometries. The modular structure with standardized connection interfaces enables the same housing components to be used across different battery module configurations, reducing the overall space and weight requirements while maintaining adaptability.
2Volume of moving object
If smaller and lighter housing systems are used, then the installation space and weight are reduced, but the stability is insufficient
Solution Approach 1:
The housing is segmented into multiple parts that are connected through standardized interfaces. This modular construction maintains stability through precise geometric fitting and connection mechanisms while keeping each individual component smaller and lighter, achieving a balance between compactness and structural integrity.
Solution Approach 2:
The housing parts are designed to accommodate different material properties, potentially using composite materials or optimized material distributions in different sections. This allows for enhanced stability in critical areas while maintaining overall lightweight and compact characteristics of the housing system.
3Manufacturing precision
If housings are designed for specific battery module geometries, then the accommodation is precise, but the production is slow and cost-intensive
Solution Approach 1:
The housing is divided into standardized modular parts that can be assembled in different configurations. This segmentation enables a single set of housing components to accommodate multiple battery module geometries, eliminating the need for custom-tooling for each geometry and significantly improving production speed and cost-effectiveness while maintaining precise accommodation.
Solution Approach 2:
The housing parts are designed with universal connection interfaces and geometric features that allow the same components to fit different battery module geometries. This multi-functionality enables standardized mass production of housing parts while maintaining precise adaptability to various battery configurations, resolving the contradiction between manufacturing precision and productivity.
4Ease of manufacture
If the housing parts are separable and assembled independently, then the manufacturing and maintenance are simplified, but the assembly complexity increases
Solution Approach 1:
The housing is segmented into independently manufacturable parts with standardized connection interfaces. While this enables simplified manufacturing and maintenance of individual components, the segmentation is designed with simple, intuitive connection mechanisms that minimize assembly complexity. The modular structure allows for parallel manufacturing of parts, reducing overall production time despite the multi-step assembly process.
