Swing Interlock Door Rail for Full-Open Breakout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ICU/CCU door systems lack a mechanism to prevent the door panel from swinging out unless it is fully open, and they do not maintain the door's stiffness when broken out.
Innovation Solution
The door system incorporates a mechanism that prevents the door panel from swinging out unless it is fully open, and includes a slide prevention feature that keeps the door panel from sliding when swung out, enhancing the door's stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door panel is allowed to swing out at any position, then ease of operation is improved, but structural stability deteriorates causing the door panel to sag
Solution Approach 1:
The interlock block assembly with rotational member is positioned in advance to block the guide rail before the door panel can swing out. This preliminary blocking action prevents the door panel from swinging at intermediate positions, thereby maintaining structural stability while still allowing controlled operation when fully open
2Stability of the object's composition
If the door panel is constrained to prevent swinging, then structural stability is improved, but ease of operation deteriorates
Solution Approach 1:
The rotational member of the interlock block assembly is designed to dynamically change position based on door panel movement. It rotates to a blocking position when the door is at intermediate angles, and rotates to an unblocking position when the door is fully open, thereby dynamically adjusting the constraint level to balance stability and operability
3Ease of operation
If the door panel is allowed to slide when swung out, then ease of operation is improved, but manufacturing precision deteriorates due to misalignment
Solution Approach 1:
The interlock block assembly with rotational member is positioned in advance to block the guide rail when the door panel is swung out. This preliminary blocking prevents any sliding movement along the guide rail, thereby maintaining manufacturing precision and alignment while still allowing the door to be swung out for accessibility

AI summary
A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.
