Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the rechargeable electric battery is maintained at optimized temperature to align with mechanical component lifetime, then energy consumption is reduced, but battery lifetime may be shortened to match mechanical component wear
Solution Approach 1:
The system dynamically adjusts the target temperature parameter of the battery based on the wear values of both the battery and mechanical components. By changing the temperature parameter according to component wear states, the system optimizes energy consumption while aligning battery lifetime with mechanical component lifetime, preventing unnecessary energy expenditure on prolonging battery life beyond the vehicle's overall useful life.
2Reliability
If the rechargeable electric battery lifetime is prolonged beyond mechanical component lifetime, then battery reliability is improved, but energy is wasted on unnecessary cooling and maintenance
Solution Approach 1:
The system continuously monitors and determines wear values for both the battery and mechanical components, using this feedback to dynamically adjust the target temperature. This feedback mechanism ensures that battery cooling and maintenance energy expenditure is optimized based on actual component states, preventing waste of energy on prolonging battery life when mechanical components are the limiting factor for vehicle lifetime.
3Loss of energy
If the target temperature is dynamically adjusted based on wear values, then energy consumption is optimized, but control system complexity increases
Solution Approach 1:
The control system integrates multiple functions into a unified approach: it determines battery wear values, determines mechanical component wear values, calculates target temperatures, and controls cooling/heating operations all through a single integrated system. This multi-functionality reduces overall system complexity compared to having separate independent systems for each function.
