Mode Control Token for Material Handling Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Material handling systems often fail to provide adequate safety measures for human operators when used in conjunction with autonomous systems, leading to potential injuries as they lack effective mechanisms to prevent or halt operations quickly in emergency situations.
Innovation Solution
A material handling system incorporating sensing panels that detect a mode control token to enable or disable sub-systems, allowing for safe operation by generating signals based on the token's proximity, enabling automatic, conveyor, traversal, or stop modes, and allowing operators to immediately halt the system by removing the token.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous sub-systems are used to improve productivity, then productivity is improved, but safety for human operators deteriorates
Solution Approach 1:
A mode control token serves as an intermediary device between the human operator and the autonomous sub-systems. The token must be physically present and activated at specific sensing panels to enable or disable sub-systems, creating a manual control layer over autonomous operations that protects human operators while maintaining productivity benefits
2Reliability
If manual intervention is required to halt operations quickly, then safety response time is improved, but ease of operation deteriorates
Solution Approach 1:
The safety control function is extracted from complex system settings and embodied in a simple physical token. Operators can immediately halt operations by simply removing or deactivating the token, eliminating the need to navigate through system menus or perform complex shutdown procedures while maintaining rapid safety response capability
3Adaptability or versatility
If multiple operating modes are implemented to enhance safety control, then safety control capability is improved, but device complexity increases
Solution Approach 1:
The mode control token serves multiple functions: it enables/disables sub-systems, selects operating modes (automatic, semi-automatic, manual), and provides safety control. This single universal control device manages the complexity of multiple operating modes without requiring separate controls for each function, maintaining ease of operation while enhancing safety control capability

AI summary
A material handling system comprising one or more sub-systems and one or more sensing panels is provided. Each sensing panel may determine whether a mode control token is within a vicinity of the respective sensing panel. When the mode control token is within the vicinity of the respective sensing panel, the sensing panel may generate a signal, and when the mode is outside of the vicinity of the respective sensing panel, the generation of the signal is halted. The material handling system may further include a processor that enables at least one of the one or more sub-systems of the material handling system in response to the generated signal and disables each of the one or more sub-systems of the material handling system in response to a halting of the generation of the signal.
