Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the generator continuously generates power, then the power supply to electric loads and battery charging is ensured, but an unnecessary load is applied to the engine
Solution Approach 1:
The patent applies dynamics by making the generator's power generation state adjustable based on operating conditions. The control device dynamically switches between power generation and non-power generation modes according to engine speed and vehicle state, optimizing the balance between power supply reliability and engine energy consumption.
Solution Approach 2:
The patent changes the operational parameters of the generator based on engine speed and vehicle state. When engine speed is high and vehicle state indicates sufficient power, the generator stops power generation; when engine speed is low or power is needed, the generator resumes power generation, thus adapting to different operational requirements.
2Speed
If the generator reduces power generation to decrease engine load, then driving property is improved, but power output may be insufficient
Solution Approach 1:
The patent implements periodic action by alternating the generator's power generation state based on detected engine speed and vehicle conditions. The generator periodically switches between generating power and not generating power, creating a rhythmic pattern that optimizes both acceleration performance and power availability.
Solution Approach 2:
The control device uses feedback from engine speed detection and vehicle state monitoring to determine when to adjust the generator's power generation. This closed-loop control ensures that the generator responds appropriately to changing operational requirements, balancing acceleration needs with power supply demands.
