Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single circuit control structure is used, then the device structure is simple, but the adaptability to control multiple circuits is poor
Solution Approach 1:
The rocker switch is designed with dual functionality: it can switch between different circuits (first circuit and second circuit) through its movable contact that can connect to different fixed contacts, and it can also adjust light intensity through the potentiometer. This multi-functional design allows a single device to control multiple circuits without requiring separate control devices for each circuit.
Solution Approach 2:
The control device is segmented into distinct functional modules: the rocker switch portion for circuit selection, the potentiometer portion for intensity adjustment, and the push button portion for auxiliary control. Each module operates independently but integrates into a unified control system, allowing the device to handle multiple circuits while maintaining operational simplicity.
2Adaptability or versatility
If a rocker button with side plates and grooves is used, then the switch control is achieved, but the multi-device centralized control capability is limited
Solution Approach 1:
The invention merges the circuit switching function and the light intensity adjustment function into a single integrated control unit. The rocker switch and potentiometer are combined such that one control device can select between multiple circuits and adjust their intensity, eliminating the need for separate control devices for each lighting device and enabling centralized control.
3Adaptability or versatility
If the rocker and spring mechanism is used, then the circuit switching is achieved, but the structural complexity increases
Solution Approach 1:
The spring mechanism automatically returns the rocker to its original position after switching, and the movable contact automatically connects to the appropriate fixed contact based on rocker position. This self-service mechanism reduces the need for additional control components and simplifies the overall structure while maintaining the circuit switching capability.

AI summary
A light adjusting device includes a housing, a light adjusting assembly and a circuit switching mechanism. The circuit switching mechanism is connected to the light adjusting assembly. The light adjusting assembly can be in communication with a first circuit and a second circuit respectively by means of the circuit switching mechanism, so as to control light-emitting elements in the first and second circuits by one light adjusting device.
