Work Support Apparatus for Plant Worker State Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to dynamically adjust the operating environment of plant workers based on their physical or psychological states, leading to potential safety hazards and inefficiencies, as they do not effectively utilize biological data to adapt the work environment or provide appropriate feedback to workers and devices.
Innovation Solution
A work support system that acquires biological data from workers, analyzes their states, and determines necessary interventions to adjust the operating environment, including feedback to both humans and devices, to ensure safer and more efficient operations by combining operation data with biological data for accurate judgments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional feedback techniques are used, then workers receive basic feedback on operation data, but the operating environment cannot be dynamically adapted to workers' physical or psychological states
Solution Approach 1:
The operating environment is made dynamic by continuously adjusting it based on real-time biological data from workers. The system modifies work conditions such as notification timing, operation permissions, and environmental parameters according to workers' changing physiological states, transforming a static environment into an adaptive one.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where biological data from workers is continuously monitored, analyzed, and used to adjust the operating environment. This feedback loop ensures that work conditions automatically adapt to workers' physical and psychological states, improving safety and efficiency.
2Reliability
If biological data is collected and analyzed to estimate worker states, then appropriate work environment adjustment becomes possible, but data processing complexity increases
Solution Approach 1:
The data analysis process is segmented into distinct functional modules: biological data collection, state estimation, and environment adjustment. Each module handles specific tasks independently, making the complex overall system more manageable and maintainable while improving the reliability of worker state assessment.
Solution Approach 2:
An intermediary analysis unit is introduced between data collection and environment adjustment. This intermediary layer processes biological data into meaningful state estimates, acting as a mediator that translates raw physiological data into actionable insights for environment modification.
3Speed
If real-time monitoring of biological data is implemented, then timely intervention can be made, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic sampling of biological data at optimized intervals. The monitoring frequency is adjusted based on work intensity, worker state, and safety requirements, achieving timely intervention while minimizing energy consumption through strategic rather than continuous data collection.

AI summary
A work support server is a work support apparatus and acquires biological data on plural workers who engage in shared work for operation of a plant, estimates a state of each of the plural workers on the basis of the biological data on the plural workers, makes an analysis of a state of each of the plural workers, and determines, on the basis of a result of the analysis, whether or not intervention in the shared work by the work support apparatus is necessary.
