Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual analysis of work elements is performed in line work with multiple work processes, then work analysis can be conducted, but the analyst's workload becomes heavy and efficiency decreases
Solution Approach 1:
The system enables automatic work element specification by having the mobile work analysis device automatically detect and specify work elements during movement through work areas, eliminating the need for analysts to manually specify each work element and significantly reducing analyst workload
Solution Approach 2:
The patent replaces manual mechanical analysis with automated image recognition and processing systems that automatically detect work elements, boundaries, and operations from captured images, substituting human effort with automated computational processes
2Measurement precision
If work elements are manually specified for each work process, then detailed analysis is possible, but the time and effort required increases significantly
Solution Approach 1:
The system performs preliminary automatic specification of work elements as the mobile device moves through work areas, preparing analysis data in advance before detailed analysis is required, thereby reducing the time needed for subsequent detailed work element analysis
Solution Approach 2:
The automatic detection and specification system performs work element identification without human intervention, maintaining high precision while dramatically reducing the time and effort required compared to manual specification methods
3Speed
If real-time work analysis is performed during work processes, then immediate feedback is available, but the complexity of simultaneous capture and analysis increases
Solution Approach 1:
The patent combines image capture, work element specification, and work analysis functions into a single integrated mobile work analysis device, allowing simultaneous execution of multiple functions without requiring separate complex systems for each operation

AI summary
A mobile work analysis device is used for work analysis based on a work moving image of a line work while recording the work moving image. The mobile work analysis device includes: a first boundary setting unit configured to receive input of a user operation and set a boundary for each work element on the work moving image; a boundary detector configured to detect recognition information associated with each work process, a boundary between a work of a first work process and a work of a second work process in the line work being recognized by the recognition information; and a second boundary setting unit configured to, when the recognition information associated with the second work process is detected, automatically set the boundary on the work moving image between the work of the first work process and the work of the second work process, based on the recognition information.
