Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vehicle frames use simple brackets to attach battery packs, then the assembly process is simple, but the level of support and protection for components is insufficient
Solution Approach 1:
The power supply assembly is divided into separate modular components including individual battery pack holders attached to cross members, allowing each component to be independently optimized for its specific function while maintaining overall system reliability
Solution Approach 2:
The patent combines multiple functions into the power supply assembly structure itself, including structural support, battery containment, and protective housing, thereby achieving enhanced protection without proportionally increasing overall device complexity
2Reliability
If battery temperature monitoring and ejector mechanisms are added to the power supply assembly, then battery safety is improved, but the device complexity increases
Solution Approach 1:
Temperature sensors are pre-installed on battery packs and the control system is pre-programmed with threshold values, enabling automatic safety responses without requiring complex real-time decision-making algorithms or additional processing complexity
Solution Approach 2:
The ejector mechanism is designed to automatically activate when temperature thresholds are exceeded, with the system self-regulating battery safety through automated ejection without requiring external intervention or complex control logic
3Ease of operation
If batteries are permanently fixed in the power supply assembly, then structural stability is maintained, but the ability to remove and replace batteries is limited
Solution Approach 1:
The battery holder design incorporates dynamic characteristics allowing batteries to be easily inserted and removed during operation while maintaining stable structural attachment when batteries are in place, achieving both ease of operation and structural stability through state-dependent connectivity
Data Source
AI summary
A system includes data processing hardware and memory hardware. The memory hardware is in communication with the data processing hardware and stores instructions that when executed on the data processing hardware cause the data processing hardware to perform certain operations. The operations include receiving a temperature corresponding to a battery, and determining whether the temperature is greater than a predetermined threshold temperature. The operations also include, when the temperature is greater than the predetermined threshold temperature, actuating an ejector to eject the battery from a power supply assembly.
