Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power supply is used for all loads, then the device structure is simple, but it cannot satisfy the different voltage requirements of multiple loads
Solution Approach 1:
The power supply unit is segmented into multiple independent power supply circuits, each dedicated to a specific load type (heater, display, vibrator). Each circuit can independently regulate voltage and current according to the specific requirements of its associated load, thereby achieving multi-voltage supply capability while maintaining clear functional separation and manageable system complexity.
Solution Approach 2:
The power supply unit is designed as a multi-functional system that can simultaneously provide different voltages to multiple loads. The control unit coordinates multiple power supply circuits to serve various functions (heating, display, vibration) from a single integrated power supply structure, achieving versatility without proportionally increasing overall system complexity.
2Adaptability or versatility
If multiple power supply circuits are provided for different loads, then various voltage requirements can be met, but the device structure becomes complex
Solution Approach 1:
Multiple power supply circuits are merged into a single integrated power supply unit with a unified control architecture. The control unit coordinates all power supply circuits simultaneously, allowing the system to provide different voltages to multiple loads through one consolidated structure rather than separate independent power supplies, thereby reducing overall device complexity while maintaining load compatibility.
Solution Approach 2:
The power supply system employs dynamic control where the control unit can adjust voltage and current parameters in real-time based on the operational state of different loads. This dynamic adjustment capability allows the system to optimize power distribution to multiple loads adaptively, achieving high versatility without requiring complex fixed circuit configurations for each possible load state.
