Furniture Guide System Cover Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide systems for movably-supported door wings in furniture face challenges in preventing collisions between the door wing and the cover during extension movements, leading to potential jamming issues.
Innovation Solution
The introduction of a coupling device that releasably couples the guiding device to the actuating device in a partial section of the guide rail, allowing the cover to be moved into the second operating position before the guiding device reaches its extended end position, thus preventing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is made movable to allow door wing extension, then the door wing can move from retracted to extended position, but the cover and door wing may collide or jam with each other
Solution Approach 1:
The coupling device is configured to engage the cover with the door wing before the door wing reaches its fully extended position. This preliminary coupling action ensures that the cover is properly positioned and secured to the door wing in advance, preventing any potential collision or jamming that would occur if the cover remained independent during the extension movement.
Solution Approach 2:
The coupling device merges the cover and door wing into a single integrated assembly during the extension process. By combining these two previously separate components, the system eliminates the risk of collision between them, as they become a unified structure that moves together as one unit.
2Reliability
If a coupling device is introduced to prevent collisions, then collision prevention is improved, but the device complexity increases
Solution Approach 1:
The coupling device is designed to automatically engage and disengage based on the relative positions of the door wing and cover during extension and retraction movements. This self-actuating mechanism eliminates the need for external actuators, control systems, or additional power sources, thereby maintaining simplicity while achieving reliable collision prevention.
Solution Approach 2:
The coupling device serves as an intermediary element between the cover and door wing, providing a simple mechanical connection that prevents collision without requiring complex control mechanisms. This intermediary component mediates the interaction between the two moving parts, ensuring safe operation through straightforward mechanical design.

AI summary
A guide system includes a guide rail and a guiding device, and is movably supported between a retracted end position and an extended end position along the guide rail. A cover can cover a front face of the guide rail, and is movable between a first operating position, in which the cover at least partially covers the front face of the guide rail, and a second operating position, in which the cover at least partially reveals the front face. An actuating device can move the cover from the first operating position into the second operating position, and a coupling device can releasably couple the guiding device to the actuating device in a partial section of the guide rail. When coupled, the actuating device can be entrained by the guiding device so as to move the cover from the first operating position into the second operating position.
