Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a light-controlled human induction LED is adopted to replace the ordinary LED, then power consumption is decreased, but lights are not available between staircases or for insufficient time delays
Solution Approach 1:
The system performs preliminary action by turning on lights before people actually arrive at a location. The motion detector triggers lights at the current staircase, and through relay network, lights at the next staircase are pre-turned on, ensuring continuous lighting availability and eliminating dark zones between staircases.
Solution Approach 2:
The system uses feedback through motion detection to dynamically control lighting. When motion is detected, the system activates lights and uses relay functionality to propagate the signal to adjacent areas, creating a feedback loop that ensures lights remain on in previously lit areas while extending illumination to new areas, thus maintaining reliability while managing energy consumption.
2Ease of operation
If the conventional remote control system through internet is used, then remote control capability is achieved, but the system becomes complex and installation and commissioning become difficult
Solution Approach 1:
The patent introduces a simple relay mechanism as an intermediary between motion detection and light control. This relay network operates locally without requiring complex internet infrastructure, yet still enables remote-like control functionality. The relay acts as a mediator that simplifies the system architecture while maintaining ease of operation through automatic scene-based control.
Solution Approach 2:
The system implements self-service through automatic scene recognition and control. The motion detector and relay network automatically identify different scenes (single staircase, multiple staircases, aisles) and adjust lighting accordingly without requiring complex remote configuration. This automation reduces system complexity while maintaining ease of operation, as the system adapts to different scenarios autonomously.

AI summary
The application discloses a smart illuminating controller which comprises transmitters and receivers. The transmitter comprises a PCB, a battery case and a shell. A Fresnel lens is at the bottom of the shell; motion detectors, light sensors and a Bluetooth module with a microcontroller are integrated on the PCB. The controller set the lights with a certain brightness according to the environment, which save the energy while provide sufficient lightings. The lightings are controlled automatically under different scenes by setting the sensitivity, distance and time delay. The demand for lightings is determined by the number of triggering signals sent by the motion detectors (5) received by the CPU at a given time. The application adopts the Bluetooth module. The time delay is able to be set infinite. The brightness for how long after the time delay is able to be set separately to meets different requirements of the scenes.
