Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional control node according to NEMA standards is used, then power transmission and basic brightness adjustment are achieved, but adjustment of multiple light shapes and color temperatures is not possible
Solution Approach 1:
The control node is enhanced to perform multiple functions beyond basic power transmission and brightness adjustment. By integrating a voltage dividing circuit and microprocessor, the same control node structure can now adjust brightness, light shape, and color temperature, making it a multi-functional control device that eliminates the need for separate control systems.
Solution Approach 2:
The control system is segmented into functional modules: the voltage dividing circuit that processes input voltage, the microprocessor that generates control signals, and multiple light-emitting element groups that produce different light shapes and color temperatures. This modular segmentation allows independent optimization of each function while maintaining overall system versatility.
2Adaptability or versatility
If multiple light-emitting element groups are used to adjust light shape and color temperature, then lighting flexibility is improved, but control signal generation complexity increases
Solution Approach 1:
The microprocessor serves as an intermediary between the voltage dividing circuit and the multiple light-emitting element groups. It receives the operating voltage, processes it to determine the desired lighting configuration, and automatically generates the appropriate control signals for each light-emitting element group, simplifying the overall control architecture despite the multiple output channels.
Solution Approach 2:
The control system is designed to automatically generate control signals based on the operating voltage without requiring external intervention for each lighting configuration change. The microprocessor self-manages the signal generation for different light shapes and color temperatures, reducing the need for complex external control circuitry.
