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 supply various voltages required by different loads
Solution Approach 1:
The power supply unit is segmented into multiple independent power supply circuits: a first power supply circuit for the heater, a second power supply circuit for the display, and a third power supply circuit for the vibration motor. Each circuit can be independently configured to provide the appropriate voltage for its specific load, enabling versatile voltage supply while maintaining clear functional separation.
Solution Approach 2:
The power supply unit is designed as a multi-functional system that can simultaneously provide different voltages to multiple loads. The controller selectively activates different power supply circuits based on the operational requirements, allowing the same power supply unit to serve multiple functions (heating, display, vibration) with different voltage requirements.
2Adaptability or versatility
If multiple power supplies are used for different loads, then various voltages can be supplied, but the device structure becomes complex
Solution Approach 1:
Multiple power supply circuits are merged into a single integrated power supply unit housed in one casing. The controller, which manages multiple power supply circuits, is also integrated into the same unit. This merging approach allows the system to provide various voltages to different loads while avoiding the complexity of having completely separate power supply devices.
Solution Approach 2:
The controller dynamically selects and activates specific power supply circuits based on the operational mode and voltage requirements. This dynamic control mechanism allows the system to adapt its power supply configuration in real-time, providing voltage versatility without requiring all power supply circuits to be permanently active or complexly interconnected.
