Worker Line of Sight Detection for Industrial Maintenance Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective methods to ensure that workers in industrial plants focus on the correct areas during maintenance tasks, leading to potential errors and inefficiencies due to inadequate line of sight detection and work area monitoring.
Innovation Solution
An apparatus and method that includes a detection unit to monitor the worker's line of sight, a storage unit to store attention-requiring areas for each task, and a determination unit to verify if these areas are being viewed correctly, with notification and input control units to manage task completion and alert workers to undetected areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If line of sight detection is implemented to monitor worker attention areas, then work safety and accuracy are improved, but system complexity and cost increase
Solution Approach 1:
The determination apparatus integrates multiple functions including area detection, line of sight tracking, work status verification, and notification delivery into a single unified system. This multi-functional integration improves work safety through comprehensive monitoring while managing system complexity by consolidating components rather than adding separate systems for each function.
2Manufacturing precision
If real-time area detection and verification are performed for each work task, then work accuracy is improved, but processing time and system resource consumption increase
Solution Approach 1:
The system pre-stores the required attention areas for each work task in advance before the worker begins the task. This preliminary preparation allows the determination apparatus to quickly verify whether the worker is viewing the correct areas during task execution, improving work accuracy without requiring complex real-time analysis or excessive processing time.
3Measurement precision
If comprehensive monitoring of all work areas is performed, then detection accuracy is improved, but ease of operation and worker convenience deteriorate
Solution Approach 1:
The determination apparatus provides feedback to the worker through notifications when the required attention areas are not being viewed. This feedback mechanism maintains high detection accuracy by monitoring all necessary areas while improving ease of operation by guiding the worker's attention rather than requiring constant manual verification or complex worker actions.
Solution Approach 2:
The system automatically monitors and verifies whether the worker is viewing the required areas without requiring manual input or continuous worker intervention. The determination apparatus independently performs detection, comparison, and notification functions, maintaining high detection accuracy while preserving worker convenience by eliminating the need for manual self-reporting or complex worker-system interactions.

AI summary
[ABSTRACT] [Means for solving the problem] There is provided an apparatus including: a storage unit configured to store, for each of a plurality of pieces of work to be performed by a worker, an area to be seen by the worker when the work is performed; a detection unit configured to detect each area seen by the worker; and a determination unit configured to determine whether each area stored by the storage unit is detected by the detection unit.
