Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If built-in temperature sensors are used in LED lighting devices, then color temperature adjustment function is provided, but the detected temperature may not be close to the real environmental temperature
Solution Approach 1:
The system separates the temperature detection function from the lighting device itself. A standalone mobile temperature signal transmitting device is used to detect environmental temperature, while the lighting device only receives and processes the transmitted temperature signal to adjust its color temperature.
Solution Approach 2:
A mobile temperature signal transmitting device acts as an intermediary between the environmental temperature source and the lighting device. This intermediary accurately detects environmental temperature and transmits it wirelessly to the lighting device, ensuring accurate temperature information transfer without the limitations of built-in sensors.
2Extent of automation
If color temperature is adjusted using built-in temperature sensors, then automatic temperature-based control is achieved, but the color temperature may not match the real environmental temperature
Solution Approach 1:
The system divides the temperature control function into two independent components: a mobile device that accurately detects and transmits environmental temperature, and a lighting device that receives the signal and adjusts color temperature accordingly. This segmentation ensures both automation and accuracy.
Solution Approach 2:
The system establishes a feedback loop where the mobile temperature signal transmitting device continuously monitors environmental temperature and sends real-time signals to the lighting device, which automatically adjusts its color temperature to match the detected environmental conditions.
3Measurement precision
If special tools are used to adjust color temperature, then precise color temperature control is achieved, but the ease of operation is reduced
Solution Approach 1:
The lighting system performs self-adjustment of color temperature based on environmental temperature detection. The mobile temperature signal transmitting device automatically detects temperature and sends control signals, eliminating the need for manual intervention or special adjustment tools.
Solution Approach 2:
The system uses automatic feedback control where environmental temperature is continuously monitored and directly translates to color temperature adjustment, removing the need for manual precision control while maintaining accurate temperature matching.
