Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional battery pack design is used, then the battery module and control module can be connected electrically, but the installation work for electrical connection is difficult and uncomfortable
Solution Approach 1:
A connection guide structure is introduced as an intermediary component between the battery module and control module. This guide structure includes a guide groove and guide protrusion that mediate the connection process, aligning the electrical connection terminals automatically and making installation convenient without increasing overall system complexity
Solution Approach 2:
The connection guide structure is pre-installed on the battery module before the control module is attached. The guide groove and guide protrusion are prepared in advance to guide the electrical connection terminals into proper alignment, eliminating the need for complex manual alignment during installation
2Volume of moving object
If the battery module and control module are closely arranged to increase energy density, then space utilization improves, but the convenience of installation work for electrical connection deteriorates
Solution Approach 1:
The connection guide structure utilizes the vertical dimension by extending the guide groove in the thickness direction of the battery module. This allows electrical connection to be facilitated in the vertical dimension while maintaining horizontal space efficiency, enabling close arrangement of modules without compromising installation convenience
3Ease of operation
If a side cover is added to guide electrical connection, then installation convenience improves, but device complexity increases
Solution Approach 1:
The connection guide structure is merged with the side cover of the battery module. The guide groove and guide protrusion are integrated into the existing side cover component rather than being separate parts, so the side cover simultaneously provides its original protective function and the new guidance function, avoiding additional components
Solution Approach 2:
The side cover is designed to perform multiple functions: it provides structural support and protection for the battery module, and simultaneously serves as a connection guide by incorporating the guide groove and guide protrusion. This multi-functionality eliminates the need for separate guidance components, maintaining device simplicity
