Sliding Door System With Displacement Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door systems for building walls are not easily accessible for repair and servicing, making maintenance cumbersome and time-consuming.
Innovation Solution
A sliding door system with a housing that allows the sliding door to be displaced into a third position, where at least one component to be serviced is accessible from outside the housing, and the sliding door can be removed without extensive disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sliding door is mounted in the housing to be displaceable for closing door openings, then the door can effectively seal the building wall, but the components become inaccessible for servicing from the outside
Solution Approach 1:
The sliding door is designed to be displaceable between a first position (for sealing) and a third position (for servicing). The door can be moved horizontally along the displacement axis to expose components for maintenance while maintaining the ability to effectively seal the door openings when closed
Solution Approach 2:
The sliding door is mounted to be displaceable not only for opening/closing operations but also along a displacement axis that enables access to components. This additional degree of freedom allows the door to move into a third position where components become accessible from outside the housing through the door openings
2Reliability
If the sliding door system is designed with a pivoting mechanism for converting displacement movement into pivoting movement of door leaves, then the door can properly close the door openings, but the structure becomes more complex and harder to service
Solution Approach 1:
The pivoting mechanism is extracted and made accessible for servicing by displacing the sliding door into the third position. This allows the complex pivoting mechanism to be removed and replaced from the outside of the housing without requiring disassembly of the entire door system
Solution Approach 2:
The sliding door system incorporates a pivoting mechanism that converts horizontal displacement movement into pivoting movement of the door leaves. This dynamic mechanism enables the door to properly close the door openings by rotating the leaves into the correct position while maintaining structural integrity
3Loss of time
If the sliding door is made easily removable from the housing for servicing, then maintenance time is reduced, but the installation security and stability may be compromised
Solution Approach 1:
The sliding door system is segmented into the door assembly and the housing, allowing the door to be independently removed from the housing for servicing. The door can be completely detached from the housing by reversing the installation steps, enabling quick maintenance while maintaining installation stability when properly assembled

AI summary
A sliding door system includes a sliding door having a first door leaf, a second door leaf and a pivoting mechanism, and a housing for installing into a building wall. The sliding door mounted in the housing is displaceable beyond opposed first and second door openings of the housing. The pivoting mechanism converts a displacement movement of the sliding door into a pivoting movement of the first and second door leaves so that the first and second door leaves expose the first and second door openings respectively in a first position of the sliding door and close the openings in a second position of the sliding door. Deactivating the pivoting mechanism allows the sliding door to be moved beyond the door openings into a third position to service a component of the sliding door and/or to remove the sliding door the first and/or second door opening.
