Telescoping Door Swing Clear Hinge Breakout Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescoping door systems in intensive care units lack the ability to create large enough openings for oversized equipment and furniture, as their breakout functionality is limited by the positioning of pivot axes and the size of pivot openings.
Innovation Solution
The telescoping door system employs a swing clear hinge that positions the pivot axes closer to the trailing jamb, allowing the sidelite and slide panels to pivot out of the header, creating a larger breakout opening by positioning the pivot axes closer to the trailing jamb and enabling the sidelite panel to swing substantially clear of the clear opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the pivot axes are positioned closer to the trailing jamb, then the breakout opening size is increased, but the door structure becomes more complex
Solution Approach 1:
The door system is divided into multiple independent panels (sidelite panel, slow slide panel, fast slide panel) that can pivot and slide independently. Each panel has its own pivot axis positioned close to the trailing jamb, allowing them to break out separately to create a large opening without requiring the entire door structure to be redesigned as a complex single unit
Solution Approach 2:
The door system transitions from a static fixed-position pivot axis design to a dynamic system where panels can pivot at multiple positions. The swing clear hinge enables panels to pivot approximately 90 degrees from the header, creating dynamic breakout configurations that maximize opening size while maintaining structural integrity through controlled movement
2Area of stationary object
If the sidelite panel is coupled to the trailing jamb by a swing clear hinge, then the pivot opening is increased, but the hinge mechanism complexity increases
Solution Approach 1:
The swing clear hinge acts as an intermediary mechanism between the sidelite panel and the trailing jamb. This specialized hinge component enables the panel to pivot approximately 90 degrees clear of the clear opening while maintaining a relatively simple connection point at the trailing jamb, rather than requiring complex support structures throughout the door assembly
Solution Approach 2:
The swing clear hinge enables movement in an additional rotational dimension, allowing the sidelite panel to pivot approximately 90 degrees from its normal position. This dimensional change creates a large pivot opening without requiring the panel to translate significantly in the horizontal plane, thus avoiding interference with other door components
3Area of stationary object
If the panels are configured to pivot out of the header in a breakout position, then the breakout opening size is increased, but the difficulty of operation increases
Solution Approach 1:
The door system operates in distinct periodic phases: normal sliding operation for routine access, and breakout pivoting operation for emergency or oversized item passage. The swing clear hinge and pivot mechanism are designed to engage naturally when breakout is required, allowing the system to transition between operational modes without complex control systems or detailed procedural knowledge
Solution Approach 2:
The breakout functionality is designed to be self-activating through natural door interaction. When force is applied to the door during a breakout event, the swing clear hinge and pivot mechanism automatically engage to rotate the panels outward, eliminating the need for operators to follow specific steps or activate complex control sequences

AI summary
A telescoping door system includes a header that spans across a doorway. A trailing jamb and a lead jamb disposed a clear opening distance from the trailing jamb defines a clear opening of the doorway. A sidelite panel is coupled to the trailing jamb by at least one swing clear hinge; the swing clear hinge comprises a fixed gear portion intermeshed with a revolving gear portion. A slow slide panel and a fast slide panel move linearly within the header. The slow and fast slide panels are configured to create a first-sized opening when positioned in the header. The sidelite panel, the slow slide panel, and the fast slide panel are configured to pivot out of the header in a breakout position such that a trailing rail of the sidelite panel is disposed at least partially outside the clear opening and in front of the trailing jamb.
