Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air deflectors are made fixed and simple in structure, then device complexity is reduced, but heat energy utilization efficiency deteriorates because the system cannot adapt to varying operational conditions
Solution Approach 1:
The air deflectors are designed as rotatable components that can dynamically adjust their orientation angles based on real-time temperature sensor feedback and operational conditions. This dynamic adjustment capability allows the system to optimize heat recovery efficiency under varying conditions while maintaining a relatively simple mechanical structure without complex actuators or control mechanisms.
2Loss of energy
If air deflectors are made rotatable and adjustable to optimize heat recovery, then heat energy utilization efficiency is improved, but device complexity increases
Solution Approach 1:
The system optimizes heat recovery by changing the orientation parameter of the air deflectors. By adjusting the angle of the deflectors, the system can redirect air flow to maximize heat transfer from the battery pack and motor to the heat exchanger, thereby improving heat energy utilization without requiring complex mechanical structures or multiple moving parts.
3Device complexity
If a simple thermal dissipation system is used, then device complexity is reduced, but adaptability to different operating conditions deteriorates
Solution Approach 1:
The thermal dissipation system incorporates temperature sensors that continuously monitor the thermal state of the battery pack, motor, and heat exchanger. This feedback information is used to control the rotation of air deflectors, enabling the system to automatically adapt to different operating conditions such as varying temperatures, cooling demands, and heating requirements without increasing overall system complexity.
