Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LED light panel uses fixed color temperature LEDs, then the manufacturing and operation are simple, but the adaptability to market requirements deteriorates
Solution Approach 1:
The LED light panel is divided into multiple groups of LEDs with different color temperatures (first group with first color temperature, second group with second color temperature). Each group can be independently controlled through separate control circuits, allowing the system to segment the color temperature output and mix different proportions to achieve variable color temperatures, thereby improving adaptability without requiring complete redesign of the entire panel.
Solution Approach 2:
The patent implements dynamic color temperature adjustment by enabling the LED light panel to change color temperature based on different working conditions or user needs. The control circuit dynamically adjusts the conduction state of different LED groups, allowing the color temperature to transition from fixed to variable, thus resolving the contradiction between simplicity and adaptability.
2Adaptability or versatility
If the LED light panel has fixed color temperature, then the device structure is simple, but the ability to respond to changing market requirements deteriorates, causing inventory pressure
Solution Approach 1:
The patent makes a single LED light panel universal by enabling it to produce multiple color temperatures. By incorporating both first and second color temperature LED groups with independent control, one panel can serve multiple market requirements (different color temperature preferences), replacing the need for multiple separate fixed-color-temperature panels, thus improving flexibility while maintaining manufacturing simplicity.
Solution Approach 2:
The patent changes the color temperature parameter of the LED light panel from fixed to variable. By controlling the proportion of different color temperature LEDs that are conducted, the system can adjust the overall color temperature output to match different market demands, allowing manufacturers to respond flexibly to changing requirements without creating inventory pressure.
3Ease of operation
If all LEDs are conducted or disconnected at the same time, then the control system is simple, but the ability to adjust color temperature deteriorates
Solution Approach 1:
The control system is segmented into multiple independent control circuits, each responsible for controlling a specific group of LEDs with a particular color temperature. This allows different segments (LED groups) to be controlled independently, enabling color temperature adjustment while maintaining relatively simple control logic for each segment.
Solution Approach 2:
The patent merges multiple LED groups with different color temperatures into a single integrated light panel that can be controlled together or separately. By combining the first and second LED groups in one panel with coordinated control, the system achieves color temperature adjustment capability while maintaining ease of operation through unified control interfaces.
