Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a large-scale control device and wiring lines are used to control illumination apparatuses, then energy saving and safety enhancement are achieved, but system cost increases
Solution Approach 1:
The system divides the illumination control into independent modular units, where each illumination apparatus operates autonomously based on local sensor detection. This segmentation eliminates the need for a centralized control device and extensive wiring, reducing system cost while maintaining energy-saving functionality through individual apparatus coordination via wireless communication.
Solution Approach 2:
Each illumination apparatus is equipped with its own detection sensor and control unit, enabling it to autonomously detect moving objects and adjust its illumination state without external control. This self-service capability allows the system to achieve energy saving and safety enhancement through decentralized autonomous operation, eliminating complex centralized control infrastructure.
2Reliability
If illumination apparatuses are continuously illuminated at specified illuminance, then safety is enhanced, but energy consumption increases
Solution Approach 1:
The illumination apparatus dynamically adjusts its operating state based on real-time detection of moving objects. When a moving object is detected, the apparatus transitions to high illuminance for safety; when no object is present, it transitions to low illuminance or off state for energy saving. This dynamic adaptation resolves the contradiction between continuous safety illumination and energy conservation.
Solution Approach 2:
The system employs periodic sensing and conditional illumination activation rather than continuous illumination. The detection sensor continuously monitors for moving objects, and the illumination is activated only during periods when movement is detected, creating a periodic on-off pattern that ensures safety when needed while minimizing energy consumption during idle periods.

AI summary
An illumination system includes a plurality of illumination apparatuses, each of the illumination apparatuses including a light source, a detection sensor for sensing presence and absence of a moving object, a wireless communication unit for transmitting a sensing signal of the detection sensor to other illumination apparatuses and for receiving a sensing signal from other illumination apparatuses and a control unit for controlling an output of the light source based on the sensing signal of the detection sensor or the sensing signal transmitted from other illumination apparatuses. If the detection sensor of one of the illumination apparatuses senses the moving object, at least one of remaining illumination apparatuses is controlled together by the sensing signal wirelessly transmitted from said one of the illumination apparatuses.
