Work Management Apparatus for Multi-Process Time Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work management techniques struggle to accurately acquire work time for each process in multi-step work operations, as they primarily focus on overall work time rather than individual process times.
Innovation Solution
A work management apparatus with detecting units and an information acquiring unit that tracks operator hand movements within defined work and component areas, allowing for the precise measurement of work time for each assembly process by distinguishing between different components and processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If work management focuses on overall work time measurement, then it is simple to implement, but it cannot acquire work time for each individual process in multi-step operations
Solution Approach 1:
The patent divides the work area into multiple component areas (first component area, second component area, etc.), each corresponding to a specific process. By detecting hand movements in each segmented area separately, the system can measure work time for each individual process while maintaining a manageable detection framework.
2Loss of information
If the system detects hand movements in multiple component areas to measure each process time, then detailed process information is acquired, but the detection and measurement complexity increases
Solution Approach 1:
The patent employs a universal detection approach where the same hand movement detection mechanism is applied across multiple component areas. This multi-functional detection system uses consistent algorithms and criteria for each area, reducing the overall difficulty of detection and measurement while ensuring complete work information is captured.

AI summary
A work management apparatus includes a first detecting unit, a second detecting unit, a third detecting unit, and an information acquiring unit. The first detecting unit detects that work was executed in a work area. The second detecting unit detects that the work in the work area ended. The third detecting unit detects that a hand of an operator entered an article area where an article relating to the work is placed. The information acquiring unit acquires information relating to the work in the work area if, from when the third detecting unit detects that the hand of the operator entered the article area until when the second detecting unit detects that the work in the work area ended, the first detecting unit detects that the work was executed in the work area.
