Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luminaires in large facilities require significant effort and time for pairing operations with terminals, as these operations necessitate electric power from the grid, making it impossible to perform before power is supplied, thus reducing installation efficiency and increasing the workload for installers.
Innovation Solution
A luminaire with a built-in power generator that generates electricity when mounted, allowing wireless communication and identification information transmission, enabling pairing operations without grid power, along with a method that involves obtaining installation states, selecting luminaires, mounting the lighting device, receiving identification information, and pairing the terminal, all while no electric power is supplied from the grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pairing operation is performed using conventional luminaire with grid power, then wireless communication can be established, but significant effort and time are required for the pairing operation
Solution Approach 1:
The luminaire performs preliminary actions by automatically transmitting its identification information and entering pairing mode immediately upon detection of the terminal device, eliminating the need for manual pairing operations. The controller automatically activates the wireless communicator and initiates the pairing process before the user completes the installation, thus resolving the technical contradiction by making the pairing operation effortless and instantaneous.
2Productivity
If pairing operation requires grid power supply, then wireless communication can be performed, but pairing cannot be performed before power is supplied
Solution Approach 1:
The luminaire serves itself by using its internal power generator to provide the necessary power for wireless communication and pairing operations. The power generator, integrated into the lighting device, automatically generates electricity when the luminaire is installed, enabling the controller to activate the wireless communicator and transmit identification information without requiring external grid power. This self-powered mechanism allows pairing operations to be performed immediately upon installation, regardless of grid power availability, thus resolving the technical contradiction by enhancing both installation efficiency and adaptability to different power conditions.
3Reliability
If manual pairing operation is required, then terminal and luminaire can be paired, but workload for installers increases
Solution Approach 1:
The system implements feedback by having the terminal device detect the identification information transmitted by the luminaire and automatically confirm the pairing status. The controller monitors whether the terminal has successfully received the identification information and completes the pairing process automatically. This feedback mechanism ensures reliable pairing while eliminating manual intervention, thus resolving the technical contradiction by maintaining pairing reliability while significantly reducing installer workload.
