Remote Work Support System for On-Site Worker Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial and maintenance settings, wearable terminals used by workers do not effectively facilitate cooperation between on-site workers and remote managers, as simply transmitting data does not allow for adequate coordination of work situations.
Innovation Solution
A remote work-support system comprising a wearable display device, a surrounding imaging device, and an information processing device that enables two-way communication and image capture, allowing managers to view work sites and worker perspectives, with features like image transmission, resolution adjustment, and user input for real-time support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is simply transmitted from wearable terminal to manager, then communication is established, but effective cooperation and coordination cannot be achieved
Solution Approach 1:
The system implements bidirectional communication where the manager can view the worker's perspective through the wearable terminal's camera and send instructions, while the worker receives guidance and can report status. This feedback loop enables effective cooperation by ensuring both parties have awareness of the work situation and can coordinate actions, resolving the information loss problem.
2Measurement precision
If high-resolution images are transmitted in real-time from work site, then detailed site awareness is achieved, but data transmission load increases
Solution Approach 1:
The system transmits high-resolution images only when the worker activates the camera function or when specific detailed viewing is required, rather than continuously transmitting all sensor data at maximum quality. This selective high-quality transmission reduces overall data load while maintaining image quality when needed, balancing measurement precision with energy loss.
3Adaptability or versatility
If multiple sensors and imaging devices are integrated in wearable terminal, then comprehensive work site monitoring is achieved, but device complexity increases
Solution Approach 1:
The wearable terminal integrates multiple sensors (acceleration, angular velocity, position) and imaging devices (camera, microphone) into a single multi-functional device that can perform various monitoring tasks including motion tracking, location tracking, visual documentation, and audio recording. This universal design achieves comprehensive monitoring capability while managing device complexity through integration rather than separate components.
