Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed installation method is used for electrical connectors, then reliability is improved, but device complexity and space occupancy increase
Solution Approach 1:
The bracket is designed to be slidable relative to the base along the height direction, transforming a static fixed installation into a dynamic adjustable one. This allows the electrical connector to be securely fixed while maintaining installation flexibility and reducing device complexity through a simpler sliding mechanism rather than complex fixed structures
Solution Approach 2:
The installation device is segmented into a base and a detachable bracket, where the bracket can be independently assembled and disassembled. This segmentation allows the electrical connector to be reliably fixed during operation while enabling easy maintenance and replacement, reducing overall device complexity
2Reliability
If traditional fixation methods are used for electrical connectors, then reliability is improved, but space utilization deteriorates
Solution Approach 1:
The bracket slides along the height direction (vertical dimension) of the battery case rather than occupying horizontal space. This dimensional change allows reliable fixation of electrical connectors while minimizing the impact on overall battery case space utilization, enabling better energy density
3Ease of operation
If more space is allocated for electrical connector installation, then ease of operation is improved, but energy density deteriorates
Solution Approach 1:
The slidable bracket provides sufficient operation space during installation by moving along the height direction, then consolidates to a compact position when fixed. This dynamic adjustment maintains ease of operation while minimizing permanent space occupancy, thereby preserving battery energy density
Solution Approach 2:
The bracket is pre-positioned in a compact state within the base, and only expands to provide operation space when installation is required. This preliminary compact arrangement ensures that sufficient space is available during installation while minimizing space occupancy during normal operation, protecting energy density
