Sliding Door Carriage with Adjustable Guide Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Larger sliding walls with multiple panels require multiple parking spaces, leading to inflexibility in panel placement due to fixed guide channel engagement, and current solutions for adjustable systems are costly and require rotating end sashes.
Innovation Solution
A switching device allows guide elements to be adjusted between engagement and release positions, enabling manual selection of parking spaces without modifying the existing track system, using a common switching device for both guide elements to ensure continuous guidance and reduce production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide element is fixed in engagement with the guide channel, then lateral forced guidance is ensured, but flexibility in selecting parking spaces is lost
Solution Approach 1:
The guide element is made dynamically adjustable between two positions: engaged with the guide channel for forced lateral guidance, and disengaged from the guide channel for flexible parking space selection. This dynamic switching capability resolves the contradiction by allowing the system to adapt its guidance characteristics based on operational requirements.
Solution Approach 2:
The position parameter of the guide element is changed between two discrete states (engaged/disengaged) to switch between forced guidance mode and flexible parking mode. This parameter change enables the system to overcome the contradiction between reliability of guidance and adaptability of parking space selection.
2Adaptability or versatility
If adjustable points are provided on the support and guide rail arrangement to access multiple parking spaces, then flexibility is improved, but outlay increases undesirably
Solution Approach 1:
The adjustment capability is extracted from the fixed support and guide rail arrangement and concentrated into a single movable guide element on the carriage. Instead of making the entire support system adjustable, only the guide element is made adjustable, significantly reducing the complexity and outlay while maintaining the ability to access multiple parking spaces.
Solution Approach 2:
The adjustable guide element acts as an intermediary between the carriage and the multiple parking spaces. It provides the necessary adaptability for accessing different parking spaces without requiring the entire support structure to be complex and adjustable, thus resolving the contradiction between flexibility and cost.
3Ease of manufacture
If a common switching device controls multiple guide elements, then production costs are reduced, but coordination of guide element positioning becomes more complex
Solution Approach 1:
Multiple guide elements are merged under the control of a single common switching device. This consolidation reduces the number of independent control mechanisms needed, lowering production costs and simplifying manufacturing while the mechanical design ensures proper coordination of the guide elements.

AI summary
A sliding wall or sliding door system comprises at least one leaf (11) which is movably suspended on a support and guide rail arrangement (14) by means of at least one carriage (12), wherein the carriage or a further carriage (12) has at least one guide element (27) for lateral forced guidance, which is provided for engagement in a guide channel (36) of the support and guide rail arrangement (14). The guide element (27) is movably mounted on a base body (19) of the carriage (12) and is adjustable by means of a switching device (39, 40) between a guide position engaging in the associated guide channel (36) and a release position moved out of the associated guide channel (36).
