Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile wall systems face challenges in efficiently guiding movable wall parts with minimal constructive effort, particularly in adjusting the alignment and distance of guide rails relative to ceilings and floors to accommodate level differences and ensure stable connection.
Innovation Solution
A rail system featuring a tension-loaded connection between a U-profile base and guide rail, utilizing adjustable screw connections and a variable-distance tensioning device to securely attach the guide rail to the ceiling or floor, allowing for easy adjustment and compensation for level differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide rail is connected to a ceiling or floor base using rigid fixed connections, then structural stability is improved, but adaptability to level differences and adjustment capability deteriorate
Solution Approach 1:
The patent applies the dynamics principle by replacing rigid fixed connections with adjustable screw connections that allow the guide rail to be dynamically positioned at different distances from the base. The screw connection mechanism enables the system to adapt to varying ceiling or floor levels while maintaining stable operation, transforming a static rigid structure into a dynamically adjustable one.
Solution Approach 2:
The patent implements parameter changes by allowing the distance between the guide rail and the base to be varied through adjustable screw connections. This parameter adjustment capability enables the system to accommodate different installation conditions and level differences, while the clamping device maintains structural stability through controlled positioning.
2Adaptability or versatility
If adjustable screw connections are used to accommodate level differences, then adaptability is improved, but connection stability and structural rigidity deteriorate
Solution Approach 1:
The screw connection mechanism provides dynamic adjustability during installation to accommodate level differences, while once positioned, the threaded connection provides rigid structural stability. This dynamic-to-static transition resolves the contradiction between adjustability and stability.
Solution Approach 2:
The adjustable screw connections allow preliminary positioning and alignment before final tightening. This preliminary action enables the system to adapt to level differences initially, and then the tightened screws provide stable, rigid connections for operational use.
3Reliability
If complex mounting structures are used to ensure stable guide rail attachment, then connection reliability is improved, but device complexity and construction effort increase
Solution Approach 1:
The patent merges the mounting function into a simple base structure that can be directly attached to ceilings or floors. By combining the base, adjustable screw connections, and clamping device into an integrated system, the patent achieves reliable guide rail attachment without requiring complex mounting structures or multiple separate components.
Solution Approach 2:
The base structure serves multiple functions: providing attachment to the ceiling or floor, accommodating level differences through adjustable screws, and supporting the guide rail with proper positioning. This multi-functionality reduces the need for additional specialized mounting components, simplifying the overall construction.
4Stability of the object's composition
If the guide rail is rigidly fixed at a predetermined distance from the base, then structural stability is improved, but ease of adjustment and installation flexibility deteriorate
Solution Approach 1:
The system transitions from a rigid predetermined distance to a dynamically adjustable distance through screw connections. During installation, the distance can be easily adjusted, and once set, the connection provides structural stability, resolving the contradiction between stability and ease of adjustment.

AI summary
The system (10) has a base i.e. U-profile body (12), for a guide rail (14) that is connected with the base by a tension-loaded connection (26, 27). A distance-variable tensioning device (38, 39) is provided between the base and the guide rail, where the tensioning device counteracts tensile load. The guide rail has a retainer for an upper-side or lower-side guiding device of a movable wall part (20) e.g. transportation carriage (18). An independent claim is also included for a mobile wall system comprising a mobile wall part.
