Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual speed adjustment is used, then the water pump can be operated, but it consumes manpower and is difficult to adjust multiple pumps simultaneously
Solution Approach 1:
The water pump system performs speed adjustment automatically through the control module and timer module, eliminating the need for manual intervention. The system serves itself by automatically timing and adjusting speeds according to preset intervals, resolving the contradiction between ease of operation and automation extent
Solution Approach 2:
The patent replaces manual mechanical speed adjustment with an electronic control system comprising control modules, timer modules, and relay groups. This substitution of mechanical manual operation with electronic automation systems resolves the contradiction by providing automatic control while maintaining operational effectiveness
2Productivity
If manual speed adjustment is used, then the water pump can be operated, but it is difficult to adjust the speed of multiple pumps on time for a long time
Solution Approach 1:
The timer module enables periodic automatic speed adjustments at predetermined time intervals. The control module automatically cycles through speed adjustments for multiple pumps according to the timing settings, significantly improving productivity while eliminating time loss associated with manual adjustments. This periodic automated action directly resolves the contradiction between productivity and time loss
3Ease of operation
If automatic speed adjustment is implemented, then operational complexity is reduced, but the circuit structure becomes more complex
Solution Approach 1:
The control system is segmented into distinct functional modules: timer modules for timing control, control modules for logic processing, and relay groups for execution. This modular segmentation manages circuit complexity by organizing functions into separate units while maintaining ease of operation through standardized interfaces and automated processes
