Universal Sliding Door Rail for Ceiling and Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding door rails require on-site drilling for installation, leading to increased installation effort and error risk, especially for end customers, and result in aesthetically compromised products with visible holes when not used for assembly.
Innovation Solution
A rail design featuring a main profile with a first leg having a carriage track and a second leg with an alternative track, allowing the rail to be rotated for universal ceiling and wall mounting without the need for on-site drilling, ensuring an aesthetically perfect surface and simplifying production, storage, and logistics by using a single product for both applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If holes are pre-drilled in both legs at the factory, then installation ease is improved, but manufacturing cost and product variety increase
Solution Approach 1:
The rail is designed with two legs where either leg can serve as the mounting leg for ceiling or wall installation. The first leg has a carriage track and the second leg has an alternative track, allowing the rail to be rotated and mounted in different orientations. This universal design eliminates the need for different pre-drilled versions for ceiling vs. wall mounting, reducing product variety while maintaining installation ease.
2Manufacturing precision
If drilling aids are attached to both legs, then drilling precision is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The invention extracts the drilling aid function from visible surfaces by providing drilling aids only on the first leg (which has the carriage track). The second leg, which serves as the mounting leg when the rail is rotated for ceiling or wall mounting, does not require external drilling aids because the carriage track on the first leg provides sufficient guidance. This eliminates visible drilling aids on the aesthetic surface while maintaining drilling precision.
3Ease of manufacture
If the rail is designed for specific ceiling or wall mounting only, then manufacturing cost is reduced, but adaptability deteriorates
Solution Approach 1:
The rail incorporates both a carriage track on the first leg and an alternative track on the second leg, allowing the same rail product to be mounted on either ceiling or wall by rotation. This universal design enables a single product to serve multiple mounting applications, maintaining manufacturing cost efficiency while achieving full adaptability for different installation scenarios.

AI summary
A track (1) for a sliding door, in particular for a glass sliding door, is designed for both ceiling and wall mounting. The track (1) comprises a main profile (2), the main profile (2) having in cross-section a first leg (3) and a second leg (4). The two legs (3, 4) are arranged together in cross-section in an arrangement area (5) and form a leg groove (6) with an angle α. The first leg (3) has a carriage track (7), the carriage track (7) being designed such that a carriage (8) for a door leaf (9) can be moved on the carriage track (7). The second leg (4) comprises an alternative track (10) for the carriage (8).
