Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door systems face high assembly costs and instability during the closing process and in the closed state, leading to a shorter service life and potential safety risks.
Innovation Solution
A sliding door system with a compact unit featuring a frame of detachably connected profile rods, where the weight and tilting moments are distributed between two identical C/U/V/L-shaped guide profiles mounted on guide rods via heavy-duty recirculating ball or roller bearings, allowing for modular assembly and reduced on-site installation complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single guide system is used to support the door leaf, then the device complexity is reduced, but the stability during closing and in closed state deteriorates
Solution Approach 1:
The single guide system is segmented into two separate linear guide systems (first linear guide and second linear guide) that are spaced apart from each other. Each guide independently supports the door leaf, distributing the load and improving stability during closing and in the closed state without significantly increasing overall device complexity.
2Ease of operation
If the door leaf is mounted laterally to the guide system, then the ease of operation is improved, but the tilting moment absorption capability deteriorates
Solution Approach 1:
The tilting moment absorption is segmented and distributed between two linear guides spaced apart from each other. Each guide absorbs a portion of the tilting moment, allowing the door leaf to be mounted laterally for easy operation while maintaining sufficient strength to absorb tilting moments without requiring additional counter bearings.
3Adaptability or versatility
If assembly is performed at the installation site, then the adaptability to different locations is improved, but the assembly work requirement increases
Solution Approach 1:
The guide system is divided into modular linear guide units that can be independently assembled and adjusted at the installation site. This segmentation allows for easy adaptation to different locations while reducing the overall assembly work requirement through standardized modular components.
4Device complexity
If weight and tilting moments are concentrated on one guide, then the device complexity is reduced, but the reliability deteriorates
Solution Approach 1:
The load support function is segmented and distributed across two linear guides spaced apart from each other. Each guide carries a portion of the door leaf weight and tilting moments, improving reliability by avoiding concentration of all loads on a single guide while maintaining reasonable device complexity.

AI summary
The invention relates to a sliding door system disposed on at least one side of an opening of a building, comprising at least one sliding door wing (2) that can be displaced in a linear manner in two linear guides (8a, 8b) that are parallel to the guide profiles (10a, 10b) having C-/U-N-/L-shape. One arm of the guide profile (10a) of one of the two linear guides (8a) supports the weight of the sliding door wing (2). The invention is characterised in that one arm of the guide profile (10b) of the other linear guide (8b) also supports the weight of the sliding door wing (2). The guide profile (10a, 10b) is mounted on the guide bar (9a, 9b) by means of a high-duty ball circuit bearing, roller guide or sliding guide. Also, double linear system supports all loads for example, weight and drive and tilting moments. Due to the compact structure, the transport costs and mounting work on the construction area of the sliding door system are kept to a minimum, enabling the complete sliding door system to be premounted or preadjusted on the workplace. Additionally, the door leaf has an essentially higher stability at least counter to the exerted load in the depth direction (opening direction) and as a result has a higher service life.
