Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch-sensitive operating element is continuously energized to enable user operation, then the ease of operation is improved, but the energy consumption increases
Solution Approach 1:
The touch-sensitive operating element is activated periodically only when needed through the proximity switch detection, rather than remaining continuously energized. When a hand approaches within the detection range, the proximity switch activates the operating element temporarily, allowing user interaction. This periodic activation significantly reduces energy consumption while maintaining ease of operation when required.
2Use of energy by moving object
If the touch-sensitive operating element remains switched off to save power, then energy consumption is reduced, but the ease of operation deteriorates
Solution Approach 1:
The proximity switch performs preliminary detection of the user's presence before activating the touch-sensitive operating element. By detecting the hand approach in advance, the system prepares the operating element for imminent use, ensuring it is activated just in time for interaction. This eliminates delays and maintains ease of operation while avoiding continuous energization.
3Adaptability or versatility
If a large number of colors and brightnesses are made available for selection, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The color and brightness selection is segmented into discrete, predetermined options rather than continuous adjustment. The memory unit stores specific color values and brightness levels that can be selected through simple touch operations. This segmentation provides sufficient adaptability for different lighting scenarios while keeping the control interface simple and the device complexity manageable.
