Work Area Interference Monitoring for Assignment Status Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to efficiently monitor the work assignment status of workers or designated tasks with a minimal amount of information, requiring detailed movement analysis.
Innovation Solution
A work assignment status monitoring system that detects the presence of workers or mobile bodies in defined areas, determining work performance based on interference with these areas, and generates information on work assignments using sensors and a monitoring apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed movement analysis is used to monitor work assignment status, then measurement precision is improved, but device complexity and information processing requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for work assignment status monitoring - specifically whether the monitoring target is present in a work area - rather than analyzing all movement details. The determination unit simply checks if the monitoring target area interferes with work areas, extracting minimal sufficient data to resolve the contradiction between precision and complexity.
Solution Approach 2:
The monitoring space is segmented into distinct work areas, each with defined boundaries. The system divides the monitoring task into checking presence in each segmented area rather than continuous detailed movement analysis, reducing overall system complexity while maintaining monitoring precision.
2Measurement precision
If continuous detailed monitoring of worker movement is implemented, then work assignment status is accurately tracked, but loss of time and processing overhead increase
Solution Approach 1:
The system extracts only presence/absence information from continuous movement data, rather than processing detailed movement trajectories. This extraction approach maintains accurate tracking of work assignment status while dramatically reducing processing time and computational overhead.
Solution Approach 2:
The patent applies partial action by monitoring only the essential aspect (presence in work area) rather than complete movement analysis. This partial monitoring approach provides sufficient information for work assignment status while minimizing time loss and processing requirements.
3Device complexity
If minimal information is used for monitoring, then device complexity is reduced, but measurement precision of work assignment status decreases
Solution Approach 1:
The patent extracts the critical presence information that is sufficient for accurate work assignment status determination. By taking out only the essential data element (whether the target is in the work area), the system achieves both minimal complexity and adequate measurement precision.
Solution Approach 2:
The system preliminarily defines work area boundaries and monitoring target areas before monitoring begins. This preliminary setup enables accurate status detection using minimal real-time information, as the framework for determination is already established.
