Independent Cable Pulling Device for Sliding Door Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for guiding sliding or folding-sliding doors on furniture walls are bulky, complex, and require extensive installation efforts due to the need for multiple deflection rollers and precise adjustments, leading to large package sizes and alignment challenges.
Innovation Solution
The use of a cable pulling device with at least two separate pulling cables, each associated with one guide system and not connected to the other, allows for independent mounting and adjustment of guide systems, reducing space requirements and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable pulling device is provided to compensate for the tilting moment, then the sliding door can be guided stably without tilting, but the device becomes bulky and complex with large package sizes
Solution Approach 1:
The cable pulling device is segmented into two independent cable systems, with each cable associated with a separate guide system. This segmentation allows each cable to independently compensate for tilting moments in its respective guide system, eliminating the need for a single complex interconnected cable system and reducing overall device complexity while maintaining stable door guidance.
Solution Approach 2:
The cable pulling device extracts its function from a single integrated system and distributes it across two separate cable-guide system combinations. By taking out the cable compensation function from a unified structure and assigning it to individual guide systems, the patent reduces the complexity and package size of the overall device while preserving the tilting moment compensation capability.
2Reliability
If multiple deflection rollers are required and fixed on exact predetermined positions, then the cable pulling device can produce its effect, but the installation effort increases substantially
Solution Approach 1:
The installation process is segmented into independent steps for each guide system, with each cable system requiring its own deflection rollers positioned at predetermined locations. This segmentation allows installers to work on one guide system at a time, reducing the complexity of coordinating multiple rollers across the entire door assembly and simplifying the overall installation process.
Solution Approach 2:
The patent specifies that deflection rollers should be fixed on exact predetermined positions during the installation process. By establishing these preliminary positions correctly, the cable pulling device can function reliably without requiring subsequent complex adjustments or readjustments, thereby reducing the overall installation effort despite the precision required for initial positioning.
3Reliability
If the guides of the guide systems need to have a distance exactly adjusted from one other, then the cable pulling device can produce its effect, but alignment errors must be precluded
Solution Approach 1:
The guide distance adjustment is segmented into independent adjustments for each guide system rather than requiring precise coordination between multiple guides across the entire door assembly. Each guide system can be adjusted and aligned independently, reducing the propagation of alignment errors and simplifying the manufacturing and installation processes while maintaining the necessary precision for cable pulling device functionality.
4Ease of manufacture
If a frame is provided on which the cable pulling device is mounted, then the cable pulling device can be installed, but the package size becomes large and extends almost over the entire furniture wall
Solution Approach 1:
The patent extracts the cable pulling device from the need for a large supporting frame that extends across the entire furniture wall. By designing the cable system to be directly integrated with the guide systems and utilizing the existing guide structure for mounting, the patent eliminates the need for a separate extensive frame, thereby reducing the occupied area while maintaining ease of manufacture and installation.

Function Achieved in This Case
This configuration enables easier assembly, smaller package sizes, and universal applicability, while maintaining stable door guidance without tilting, by allowing independent adjustment of guide systems without requiring readjustment of the other system.
Implementation Method 1
a cable pulling device for compensating for a tilting moment of the carrier or of the sliding door or folding sliding door arranged thereon, respectively, about a tilting axis by a return moment

AI summary
An arrangement includes a first guide system to be fixed to a furniture wall and a second guide system to be fixed to the furniture wall a vertical distance from the first guide system. Each of the two guide systems has a guide and a guide body displaceably arranged on the guide, a carrier to which the sliding door or folding-sliding door can be fixed, and a cable pulling device for compensating for a tilting moment of the carrier. The cable pulling device includes a first pulling cable arranged between the guide body of the first guide system and an end of the guide of the first guide system and without connection to the second guide system. A second pulling cable is between the guide body of the second guide system and an end of the guide of the second guide system and without connection to the first guide system.
