Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing threshold designs for sliding doors are complex and require numerous sealing measures and assembly components, complicating the installation process and drainage functionality.
Innovation Solution
A threshold profile with a substantially flat, horizontally oriented top for easy mounting of sliding doors, incorporating a drainage chamber below the top with concealed drainage openings, and grooves for running rails and adapter profiles, allowing for simple assembly and efficient drainage without additional adapter pieces or sealing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threshold profile with inclined upper side is used for drainage, then drainage function is improved, but mounting complexity increases due to need for adapter pieces and sealing measures
Solution Approach 1:
The patent combines the drainage function and the mounting surface into a single integrated threshold profile. The U-shaped cross-section profile includes an inclined upper side for drainage and a horizontal lower side for mounting, eliminating the need for separate adapter pieces and reducing sealing requirements.
Solution Approach 2:
The patent introduces a vertical dimension solution by creating a stepped configuration with the inclined upper side and horizontal lower side at different elevations. This allows the mounting surface to be horizontal while the drainage surface remains inclined, resolving the contradiction between drainage effectiveness and mounting simplicity.
2Adaptability or versatility
If multiple components are used for threshold and cover profile, then drainage and mounting functions are improved, but assembly complexity increases
Solution Approach 1:
The patent merges the threshold profile and cover profile into a single integrated component with a U-shaped cross-section. The profile includes side walls, an inclined upper side for drainage, and a horizontal lower side for mounting, consolidating multiple functions into one piece that simplifies assembly.
Solution Approach 2:
The single threshold profile performs multiple functions: it provides the mounting surface for the fixed panel, enables drainage through its inclined upper side, and integrates the cover profile functionality. This multi-functional design reduces the number of components and simplifies assembly.
3Reliability
If adapter pieces and sealing elements are added to threshold profile, then mounting reliability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the mounting surface directly into the threshold profile's horizontal lower side, eliminating the need for separate adapter pieces. The sealing function is incorporated into the profile design itself, reducing the number of separate sealing elements required.

AI summary
A threshold for a sliding door (1) comprises a threshold profile (5) designed as a hollow profile, on the upper surface (50) of which at least one guide rail (10) for a sliding leaf (3) is provided, along which the sliding leaf (3) can be moved from a closed position to an open position in front of or behind an adjacent sliding leaf or a fixed panel (2), wherein the threshold profile (5) has a substantially flat, horizontally oriented upper surface (50) in the installed state and a drainage chamber (54) is formed below the upper surface (50). The invention further relates to a sliding door with such a threshold.
