Workwear Light Receiver for Individual Worker Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional worker monitoring systems in factories, such as those in food or pharmaceutical industries, fail to manage worker actions on an individual basis due to workers wearing similar or identical workwear, making it difficult to identify and track specific workers from captured images.
Innovation Solution
A worker management device and system that includes a light receiver on workwear to receive identification information via visible light, a controller to process this information, and a communication unit to communicate with a control device, allowing for proper management of worker actions on a per-worker basis by associating each worker with unique identification through lighting devices and biometric authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cameras are installed to monitor worker actions, then worker monitoring capability is improved, but individual worker identification capability deteriorates
Solution Approach 1:
The system segments worker identification by combining general visual monitoring with individual identification tags. Cameras capture worker images while separate identification systems (tags, RFID, or visual identifiers on workwear) provide individual differentiation, allowing both group monitoring and individual tracking to function simultaneously
Solution Approach 2:
An intermediary identification system is introduced between the camera and the worker. This could be a tag worn by the worker, a distinctive marker on workwear, or a biometric sensor that mediates between the visual capture system and the individual worker, enabling precise identification without compromising monitoring coverage
2Reliability
If workers wear uniform workwear for hygiene management, then hygiene standardization is improved, but worker individuality deteriorates
Solution Approach 1:
The uniform workwear maintains global homogeneity for hygiene purposes, but incorporates local differentiation through individual identification elements. These could be colored patches, numbered tags, or RFID tags positioned on the workwear, allowing the bulk of the clothing to remain standardized while providing unique identifiers for each worker
Solution Approach 2:
The workwear serves multiple functions: it provides hygiene protection through standardized design while simultaneously carrying individual identification information. The identification tag or marker on the workwear performs dual roles of maintaining uniform appearance and enabling worker-specific identification and tracking

AI summary
A worker management device that manages a worker wearing workwear includes: a main body; a light receiver that is provided on a part of the main body that is exposed when the main body is attached to the workwear, and receives light including predetermined identification information; a controller connected to the light receiver; and a communication unit connected to the controller.
