Light Device Positional Information Management via End-Mounted Wireless Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positional information management systems require new power supply installations, increasing costs, and may obstruct light sources due to integrated wireless communication modules in light devices.
Innovation Solution
A light device with a light emitting module, caps for mounting on a lighting fixture, and a positional information transmission part that transmits predetermined information without obstructing the light, using a wireless communication module positioned to avoid interference with the light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a wireless communication module is incorporated in the light device to transmit positional information, then the system can determine and manage the position of wireless terminals, but the wireless communication module may obstruct the light irradiated from the light source depending on its placement
Solution Approach 1:
The patent applies dimensional positioning by placing the wireless communication module at the end of the light device rather than in the central light path. This spatial repositioning moves the module to a different dimension (end position vs. central position), allowing it to transmit positional information without obstructing the light irradiation from the light source.
Solution Approach 2:
The patent introduces the cap as an intermediary component that houses the wireless communication module. The cap serves as a mediator that allows the module to be integrated into the light device structure while preventing it from obstructing the light path, as the module is positioned within the cap at the end of the light device.
2Loss of information
If new power supply installation work is carried out to supply power to transmitters for positional information, then the transmitters can transmit positional information to wireless terminals, but the introduction cost increases
Solution Approach 1:
The patent applies multi-functionality by enabling the light device to serve dual purposes: providing illumination through its light source and transmitting positional information through the integrated wireless communication module. The light device's existing power supply is used to power both functions, eliminating the need for separate power supply installations that would be required if dedicated transmitters were used.
Solution Approach 2:
The patent combines the positional information transmission function with the existing light device structure. By integrating the wireless communication module into the light device and using the light device's existing power supply, the system merges two functions (illumination and position transmission) into a single device, avoiding the need for separate power supply infrastructure.
