Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional interconnection methods are used for energy storage modules, then reliable connection between modules is achieved, but device complexity and assembly difficulty increase due to extensive additional connection components
Solution Approach 1:
The patent combines mechanical support, electrical connection, and coolant flow functions into a single integrated interconnection means. The interconnection means includes contact surfaces for electrical connection, structural elements for mechanical support, and coolant channels for thermal management, all merged into one component that connects two energy storage modules simultaneously, eliminating the need for separate connection components
Solution Approach 2:
The interconnection means is designed to perform multiple functions simultaneously: it provides mechanical support to hold modules together, establishes electrical contact between modules for current flow, and enables coolant flow for thermal management. This multi-functional design reduces the overall number of components needed in the energy storage system
2Reliability
If traditional interconnection methods are used for energy storage modules, then stable connection is achieved, but ease of operation and assembly are reduced due to extensive assembly steps
Solution Approach 1:
By merging multiple connection functions into a single interconnection means, the assembly process is simplified from multiple separate steps (mechanical assembly, electrical connection, coolant routing) into one integrated operation, improving ease of assembly while maintaining stable connections
Solution Approach 2:
The interconnection means is pre-designed and pre-configured with all necessary connection elements (contact surfaces, structural features, coolant channels) integrated before assembly, allowing for quick and easy module connection without requiring complex assembly procedures or multiple components to be installed separately
3Temperature
If cooling elements are arranged between flat cells, then cooling efficiency is improved, but device complexity increases due to additional cooling components
Solution Approach 1:
The cooling function is merged with the interconnection means by integrating coolant channels directly into the interconnection component. This allows coolant to flow between modules through the same structure that provides mechanical and electrical connection, eliminating the need for separate cooling plates or heat sinks between cells
Solution Approach 2:
The interconnection means serves as both a structural connector and a thermal management component, with coolant channels embedded within the same component that provides mechanical support and electrical connection, achieving multi-functionality without increasing overall device complexity
