Floor Guide with Removable Central Web for Sliding Door Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor guides for sliding doors require removal of fixedly installed floor coverings for maintenance access, leading to high costs and aesthetic issues due to unsightly stripe-shaped floor elements.
Innovation Solution
A floor guide design featuring a removable central web that allows access to running gears without lateral floor covering removal, enabling the sliding door to be uninstalled and reinstalled without damaging the floor coverings, using either screw-release or tool-free mechanisms with latchable central web parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If floor coverings are fixedly installed laterally to the guide channel, then the floor covering stability and aesthetic appearance are improved, but the accessibility to roller bearings for maintenance is worsened
Solution Approach 1:
The floor covering is divided into two segments: lateral floor coverings that are fixedly installed for stability and aesthetics, and a central floor covering that is removable for maintenance access. This segmentation allows each part to serve its specific function without compromising the other.
Solution Approach 2:
The central floor covering is extracted as a separate removable component from the overall floor covering system. This extracted central portion can be removed to provide access to roller bearings while the lateral floor coverings remain fixed to maintain floor stability and aesthetic appearance.
2Ease of manufacture
If the gap width above the rails is kept narrow, then the aesthetic appearance is improved, but the access to roller bearings for maintenance is worsened
Solution Approach 1:
The floor covering system transitions from a static fixed installation to a dynamic configuration where the central floor covering can be removed. This dynamic capability allows the system to switch between aesthetic mode (with narrow gap) and maintenance mode (with access to roller bearings).
3Stability of the object's composition
If lateral floor coverings engage across the interior of the floor guide, then the floor covering stability is improved, but the removal of running gears for servicing is prevented
Solution Approach 1:
The floor covering is segmented into lateral portions that engage with the guide channel for stability and a central portion that can be removed for maintenance. This segmentation resolves the conflict between stability and accessibility.

AI summary
A floor guide for sliding doors (19) is provided with a guide channel (1). A center piece (39) is arranged in the guide channel (1) and is detachably fastened to the floor of the guide channel (1) so that the profiled flange (21) at the lower edge of the sliding door (19) can be introduced and removed.
