Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If recharging starts immediately when connected to the electrical network, then charging time is reduced, but transformer stress and heating increase
Solution Approach 1:
The charging process is divided into periodic intervals with alternating charging and pause phases. The controller monitors transformer temperature and load, activating charging only during safe periods when transformer stress is within acceptable limits, thus preventing continuous overheating while still achieving reasonable charging speed.
Solution Approach 2:
Before initiating charging, the controller performs a preliminary assessment of transformer load and temperature conditions. This preliminary action determines whether immediate charging is safe or if a pause is required first, preventing harmful transformer stress before it occurs.
2Ease of operation
If charging continues until the battery is full or user disconnects, then user convenience is maintained, but energy efficiency is reduced
Solution Approach 1:
The controller continuously monitors battery state of charge, transformer conditions, and user-defined parameters. Based on this feedback, the controller dynamically adjusts charging activation/deactivation timing to optimize energy efficiency while respecting user convenience requirements and battery charge levels.
Solution Approach 2:
The system changes operational parameters (charging power, activation timing) based on real-time conditions. When transformer stress is high or battery is nearly full, the controller modifies charging parameters to reduce energy waste while maintaining user convenience through flexible disconnection options.
3Adaptability or versatility
If charging is performed during high-load periods, then user schedule flexibility is maintained, but transformer aging accelerates
Solution Approach 1:
The system implements periodic charging intervals that avoid continuous operation during high-load periods. By alternating between charging activation and pause phases based on transformer load monitoring, the system reduces cumulative transformer stress and heating while still providing charging service during user-available periods.
Solution Approach 2:
The controller performs preliminary monitoring of transformer load conditions before activating charging. This preliminary assessment prevents charging initiation during periods that would excessively accelerate transformer aging, thereby extending transformer lifespan while maintaining user schedule flexibility through alternative charging timing options.
