Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat sinks are arranged on two sides of the front portion of the heat exchanger to enable full advantage of waste heat, then heat energy utilization is improved, but device complexity increases due to the need for particular air deflectors to redirect heat source
Solution Approach 1:
The patent combines the heat sinks with the heat exchanger by arranging them on two sides of the front portion of the heat exchanger, creating an integrated thermal management assembly that efficiently captures and utilizes waste heat from battery and motor components
Solution Approach 2:
The patent employs rotatable and adjustable air deflectors that can dynamically redirect air flow based on operating conditions, allowing the system to adaptively optimize heat source management for the heat exchanger under various thermal and operational states
2Productivity
If air deflectors are made rotatable and adjustable to redirect air flow through heat sinks and heat exchanger, then thermal management efficiency is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent divides the air deflector system into multiple rotatable and adjustable components that can be independently controlled, allowing each segment to be optimized for specific flow redirection tasks while maintaining overall system efficiency
Solution Approach 2:
The air deflectors serve multiple functions: they redirect air flow to the heat exchanger, control the amount of air passing through heat sinks, and can be adjusted based on different operating conditions, making them a multi-functional component that addresses various thermal management requirements
3Loss of energy
If sensors are added to sense working temperatures and environmental temperatures of battery pack and motor, then heat energy utilization is optimized, but device complexity and cost increase
Solution Approach 1:
The patent incorporates sensors that continuously monitor working temperatures and environmental temperatures of the battery pack and motor, providing feedback to the control system which then adjusts air deflector positions to optimize heat energy utilization based on real-time thermal conditions
