Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single LED control box is used without multiple independent output control interfaces, then the device complexity is reduced, but the adaptability to different lighting scenarios deteriorates
Solution Approach 1:
The control box is segmented into multiple independent output control interfaces (first output control interface, second output control interface, etc.), each capable of independently controlling different LED lamps. This segmentation allows the system to adapt to different lighting scenarios while maintaining a unified control box structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The control box is designed with multi-functionality by incorporating multiple independent output control interfaces that can work independently or in combination. Each interface can control different LED lamps according to different control signals, enabling the single control box to serve multiple lighting scenarios simultaneously, thus improving adaptability without proportionally increasing complexity.
2Reliability
If physical wire connections are used for LED control, then the connection reliability is improved, but the installation cost and installation time increase
Solution Approach 1:
The patent replaces the mechanical wire connection system with a wireless communication system. Wireless switches communicate with the control box through wireless signals (infrared, radio frequency, etc.), eliminating the need for physical connecting wires. This substitution maintains control reliability through wireless protocols while dramatically reducing installation time and complexity, as no wire routing or physical connections are required.
3Use of energy by moving object
If all LED lamps are controlled uniformly through a single interface, then the device complexity is reduced, but the energy consumption increases due to inability to control individual lamps
Solution Approach 1:
The control interface is segmented into multiple independent output control interfaces, each capable of independently controlling specific LED lamps. This allows the system to activate only the necessary lamps based on actual lighting needs, reducing energy consumption compared to uniform control of all lamps. The segmentation of control interfaces justifies the increased complexity by enabling energy-efficient selective operation.
Solution Approach 2:
Different output control interfaces can be assigned different control characteristics and functions tailored to specific lighting zones or lamps. This local quality approach allows optimized energy management where each interface can independently regulate its controlled LEDs based on local requirements, reducing overall energy consumption while the added complexity is justified by the localized optimization capabilities.
4Adaptability or versatility
If multiple independent output control interfaces are added to the control box, then the adaptability to different lighting scenarios is improved, but the device complexity increases
Solution Approach 1:
The control box is segmented into multiple independent output control interfaces, each capable of independently controlling different LED lamps. This segmentation allows the system to adapt to different lighting scenarios while maintaining a unified control box structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The control box is designed with multi-functionality by incorporating multiple independent output control interfaces that can work independently or in combination. Each interface can control different LED lamps according to different control signals, enabling the single control box to serve multiple lighting scenarios simultaneously, thus improving adaptability without proportionally increasing complexity.
