Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If energy is provided from vehicle batteries without considering health levels, then energy supply availability is improved, but battery degradation and reliability deteriorate
Solution Approach 1:
The system changes the parameter of energy distribution by introducing health level as a controlling variable. Energy is allocated based on battery health metrics (state of charge, impedance, temperature) rather than uniformly, allowing healthier batteries to provide more energy while protecting degraded batteries from further stress
Solution Approach 2:
The system implements continuous monitoring of battery health parameters and uses this feedback to dynamically adjust energy distribution. The controller receives real-time data on state of charge, impedance, and temperature, then modulates energy flow accordingly to prevent degradation while maintaining supply availability
2Reliability
If energy distribution is based on battery health levels, then battery degradation is reduced, but system complexity increases
Solution Approach 1:
The system segments the energy management function into distinct monitoring and control components. Separate modules handle impedance measurement, state of charge calculation, temperature monitoring, and energy flow control, making the complex system more manageable and maintainable
Solution Approach 2:
The controller acts as an intermediary between the batteries and the energy-consuming devices. It mediates the energy flow by processing health data and making distribution decisions, isolating the complexity from both the batteries and the external devices
3Power
If multiple batteries are used to meet peak energy demand, then energy supply capacity is improved, but coordination difficulty and system complexity increase
Solution Approach 1:
The system merges multiple battery sources into a unified energy supply system. The controller combines the output of multiple batteries according to their health levels, creating a single coordinated power source that meets peak demand while managing individual battery protection
