Remote Access Warning with Proximity Sensing for Local Operator Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote access to automated processing systems for biological specimen testing can lead to workflow interference and potential collisions with local operators due to the lack of awareness of the remote operator's presence, as they may not be aware of people near the equipment during operations like maintenance or loading.
Innovation Solution
A Remote Control Warning Device (RCWD) is introduced, which includes a proximity sensor, warning devices, and a user interface to detect the presence of local operators within a safety zone, provide audible and visual warnings, and allow local operators to reject or suspend remote control sessions, ensuring safety and awareness during remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote access to automated processing system is enabled, then operational flexibility and remote control capability are improved, but safety and awareness of local operators are worsened due to lack of notification
Solution Approach 1:
The system performs preliminary action by notifying the local operator before the remote operator takes control of the automated processing system. The notification is displayed on the local operation device, allowing the local operator to prepare for the upcoming remote operation and avoid potential workflow interference or safety issues.
Solution Approach 2:
The system implements feedback by providing real-time notification to the local operator when a remote operator requests or establishes control. This feedback loop ensures that the local operator is aware of the remote operation status and can take appropriate actions to maintain safety and workflow efficiency.
2Productivity
If remote operator takes control without notification, then operational efficiency is improved, but safety awareness of local operators deteriorates
Solution Approach 1:
The system performs preliminary notification to the local operator before the remote operator takes control, ensuring that safety awareness is maintained while still enabling efficient remote operation. The notification is displayed in advance, allowing the local operator to prepare appropriately.
3Device complexity
If local operator is not notified of remote access, then device complexity is reduced, but harmful effects from workflow interference increase
Solution Approach 1:
The notification module integrated into the local operation device serves multiple functions: it displays remote operator notifications, provides safety warnings, and maintains workflow coordination. This multi-functionality approach adds minimal complexity while effectively preventing workflow interference.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The RCWD effectively prevents collisions and workflow interference by alerting local operators of impending or active remote control sessions, allowing them to take necessary precautions, thereby enhancing safety and operational efficiency in automated processing systems.
