Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If only dynamic braking is used for charging the energy storage module, then the control system is simple and easy to operate, but fuel efficiency is reduced and battery degradation increases
Solution Approach 1:
The control system dynamically adjusts charging strategies by evaluating multiple charging options (dynamic braking, regenerative braking, engine-driven charging) and selecting the optimal combination based on real-time vehicle operating conditions, route information, and energy storage module state, thereby improving fuel efficiency without excessive complexity
Solution Approach 2:
The system changes operational parameters by transitioning between different charging modes and adjusting charging timing based on route segments, vehicle load, and energy storage module charge levels, enabling optimized fuel consumption through parameter variation rather than fixed control logic
2Reliability
If multiple charging options are evaluated and implemented, then fuel efficiency is improved and battery life is extended, but the control system complexity increases
Solution Approach 1:
The system performs preliminary evaluation of multiple charging options and their impact on battery life before executing charging operations, using route information and energy efficiency factors to pre-determine optimal charging strategies that extend battery operational life
Solution Approach 2:
The control system continuously monitors energy storage module charge levels, charging option availability, and vehicle operating conditions, using this feedback to adjust charging strategies in real-time and select options that minimize battery degradation while maintaining fuel efficiency
3Use of energy by moving object
If charging options other than dynamic braking are utilized, then energy efficiency is improved, but additional equipment and infrastructure are required
Solution Approach 1:
The control system implements multi-functionality by evaluating and selecting from multiple charging options (dynamic braking, regenerative braking, engine-driven charging) that can be integrated into existing hybrid vehicle systems, improving energy efficiency without requiring completely new equipment
Solution Approach 2:
The system uses an intermediary control algorithm that coordinates between different charging mechanisms and energy storage module, enabling efficient use of available charging options while managing the complexity of integrating multiple charging sources
