Laboratory Workstation Door for Safe Access During Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laboratory workstations face challenges in protecting the working area from user interference while allowing controlled access, especially when automated processes are ongoing.
Innovation Solution
A movable door for laboratory workstations that transitions between safety, access, and loading positions, controlled by a processing unit, allowing limited manual access without disrupting automated processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protection screen is used to separate the working area from user interference, then user safety is improved, but user access to the working area is restricted
Solution Approach 1:
The protection screen is designed as a movable door that can dynamically change its position between a closed state (providing protection) and an open state (providing access). The door is controlled by a processing unit that receives user input to transition between these states, allowing the system to adapt its protective function based on operational needs.
Solution Approach 2:
The door structure includes an access opening that is separated from the main door body. This segmentation allows the access opening to be independently positioned or sized to provide limited access while the main door remains closed for protection, resolving the contradiction between safety and access.
2Ease of operation
If the protection screen is removed to allow user access, then ease of operation is improved, but protection from user interference is lost
Solution Approach 1:
Instead of removing the protection screen entirely, the system dynamically positions the door and access opening based on operational requirements. The processing unit controls the door's movement to provide access only when needed, while maintaining protection during automated operations.
Solution Approach 2:
The access opening provides localized access to specific areas of the working area without compromising the overall protective function of the door. This allows users to access specific zones while the rest of the working area remains protected during automated operations.
3Productivity
If automated processes are running continuously, then productivity is improved, but user access to load equipment is restricted
Solution Approach 1:
The door system dynamically adjusts its position to accommodate both continuous automated operations and periodic user access requirements. The processing unit coordinates door movement with automated process timing, allowing users to load equipment during appropriate intervals without disrupting overall productivity.
Solution Approach 2:
The system can be configured to pause or slow down automated processes before user access is required, allowing equipment loading to occur without interrupting the overall automated workflow. This preliminary coordination maintains productivity while enabling necessary user access.

AI summary
A door for a laboratory workstation is disclosed. The laboratory workstation has a horizontally extending work surface for providing a working area. The door is movable in relation to the work surface in a vertical direction perpendicular to the work surface between a safety position, in which the door closes the working area for manual access of a user, an access position in which the working area is open for manual access of a user, and a loading position.
