Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for analyzing work performance statuses of workers in factories do not effectively visualize actions forming a work step in association with the objects handled by the worker, limiting the detail and clarity of the analysis.
Innovation Solution
A work analyzing device and method that utilize video recordings to recognize target objects and actions performed by workers, outputting analysis result information as a time series representation of action statuses associated with each type of object, enabling detailed visualization of work performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video recordings are analyzed to visualize worker actions in units of process steps using Gantt charts, then users can easily grasp overall work performance status, but users cannot grasp detailed actions associated with specific components and work tools
Solution Approach 1:
The patent segments the visualization into two levels: process step level (using Gantt charts) and action level (using timeline graphs). This segmentation allows users to first grasp overall work performance through process steps, then drill down into detailed actions associated with specific components and work tools, resolving the contradiction between ease of operation and information detail.
Solution Approach 2:
The patent adds a new dimension to the visualization by introducing timeline graphs that display actions in chronological order with associations to components and work tools. This dimensional addition allows simultaneous presentation of both macro-level process status and micro-level action details, overcoming the limitation of traditional single-dimension Gantt charts.
2Device complexity
If traditional Gantt charts are used to display work performance by process steps, then visualization is simple and easy to understand, but detailed action information associated with objects is not provided
Solution Approach 1:
The patent merges Gantt charts and timeline graphs into a integrated visualization system. The Gantt chart displays process step progress while the timeline graph displays detailed actions with object associations. Both visualizations work together to provide both simplicity and detailed information, resolving the contradiction between device complexity and information completeness.
Solution Approach 2:
The patent introduces an intermediary mechanism that links process steps to detailed actions. The system identifies and associates actions with specific components and work tools, acting as a mediator between the high-level process view and the low-level action details, thereby preserving information without overwhelming the user with complexity.
3Productivity
If analysis focuses on process step level, then overall work efficiency can be assessed, but detailed performance metrics for specific actions and objects are lost
Solution Approach 1:
The patent implements a dynamic visualization system that can switch between different levels of detail. Users can dynamically adjust the view to focus on either process step level for overall efficiency assessment or action level for precise measurement of specific actions and objects, resolving the contradiction between productivity assessment and measurement precision.

AI summary
Provided is a system configured to analyze and visualize a worker's actions forming a work in association with an object handled by the worker such as a component or a work tool, thereby enabling a user to easily grasp a work performance status of the worker in detail. The system recognizes types of objects handled by the worker, while recognizing types of the worker's actions associated with each object; and outputs, as a visualized analysis result, a time series representation of a status of the actions associated with each object. Specifically, action fields extending along a horizontal time axis are provided in a row for respective types of objects. Shown in each action field is action bars, each of which extends horizontally to a length representing a time period during which a corresponding action is performed.
