Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional display interfaces are used for temperature setpoint adjustment, then the device structure remains simple, but the visual feedback precision and user interaction efficiency deteriorate
Solution Approach 1:
The user interface is segmented into multiple independent indicator lights, each representing a specific temperature setpoint level. This segmentation allows the system to display temperature adjustments with fine granularity using discrete visual elements, achieving high resolution without requiring a complex continuous display device.
Solution Approach 2:
The indicator lights utilize color changes to represent different temperature setpoint states. By assigning specific colors to different temperature levels or adjustment directions, the system provides intuitive visual feedback with simple binary light states, maintaining interface simplicity while enhancing information conveyance.
2Manufacturing precision
If detailed visual feedback is provided for temperature adjustment, then user control precision improves, but the energy consumption of the display device increases
Solution Approach 1:
The indicator lights operate in a periodic manner, activating only when temperature setpoint adjustment is needed or when users interact with the control interface. This periodic operation significantly reduces energy consumption compared to continuous display, while still providing detailed visual feedback for precise temperature control during active use.
