Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing control circuits are used for air pump voltage and speed regulation, then pressure and flow rate can be adjusted, but the control circuit structure becomes complicated and difficult to implement
Solution Approach 1:
The control circuit is segmented into two independent circuits: a chopper power supply circuit for voltage regulation and a full bridge rectifier circuit for speed regulation. Each circuit operates independently with its own control switch, allowing simplified individual circuit design while providing comprehensive regulation capability through circuit selection.
Solution Approach 2:
The system dynamically switches between the chopper power supply circuit and the full bridge rectifier circuit based on operational requirements. A control switch selects which circuit connects to the motor, enabling adaptive regulation of pressure and flow rate without requiring a single complex circuit to handle all functions.
2Ease of manufacture
If a single control circuit is used for both voltage and speed regulation, then the circuit design becomes complex, but using separate circuits simplifies implementation
Solution Approach 1:
The control system achieves multi-functionality by providing two separate circuits that can be switched between. The chopper power supply circuit handles voltage regulation for pressure control, while the full bridge rectifier circuit handles speed regulation for flow rate control. Together they provide universal regulation capability across different operating conditions.
Solution Approach 2:
A control switch acts as an intermediary between the two circuits and the motor. This switch selectively connects either the chopper power supply circuit or the full bridge rectifier circuit to the motor, enabling simple implementation of each circuit while maintaining the ability to perform both voltage and speed regulation functions.
