Dynamic Prohibited Area Control for Mobile Body Work Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety systems in construction sites and warehouses fail to prevent efficiency reductions when workers and mobile bodies, such as AGVs or forklifts, operate in the same area, leading to potential collisions and work delays.
Innovation Solution
A management system that acquires information on the work carried out by mobile bodies and specifies prohibited areas for human entry based on the work being performed, using control means to regulate human access to these areas in accordance with the scheduled work times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If workers are allowed to enter the attention required area near mobile bodies, then worker accessibility and flexibility are improved, but the risk of collision between workers and mobile bodies increases
Solution Approach 1:
The system dynamically adjusts the prohibited area boundaries and regulatory measures based on the real-time work status of mobile bodies. When mobile bodies are performing work, the system specifies prohibited areas and implements entry regulation. When work is not being performed, the restrictions are lifted, allowing worker access. This dynamic adjustment resolves the contradiction by making the area accessible when safe and restricted when dangerous.
Solution Approach 2:
The system changes the operational parameters of the area (from accessible to prohibited) based on the work status parameter of mobile bodies. By monitoring whether mobile bodies are actively working, the system transitions the area status between accessible and restricted states, thereby managing both worker accessibility and collision risk through parameter variation.
2Reliability
If prohibited areas are enforced to prevent collisions, then safety is improved, but work efficiency decreases due to restricted worker access
Solution Approach 1:
The system implements periodic enforcement of prohibited areas based on the work cycles of mobile bodies. During work periods, entry regulation is enforced to ensure safety. During non-work periods, the regulation is relaxed to allow worker access and maintain productivity. This periodic application of safety measures ensures both safety during critical operations and efficiency during safe periods.
Solution Approach 2:
The prohibited area enforcement is dynamic rather than static. The system activates safety restrictions only when mobile bodies are performing work, and deactivates them when work is completed or paused. This dynamic enforcement maintains safety during high-risk periods while preserving worker accessibility and productivity during low-risk periods.
3Object-affected harmful factors
If workers must avoid contact with mobile bodies during work, then collision prevention is improved, but work efficiency is reduced due to operational constraints
Solution Approach 1:
The management system acts as an intermediary between workers and mobile bodies. It monitors mobile body work status and automatically specifies prohibited areas and entry regulations, eliminating the need for workers to manually avoid mobile bodies. This intermediary control prevents collisions through automated spatial management rather than relying on worker caution, thereby maintaining efficiency.
