Sliding Door Driver Rotation for Universal Roller Carrier Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door or window systems with integrated roller carriers and drivers are complex and costly to produce, store, and assemble, requiring specific designs for left and right cantilevered drivers, and are not easily adaptable to different closing directions without replacing the entire roller carrier.
Innovation Solution
The driver can be rotated and attached to the roller carrier with a 180° rotational offset, allowing for universal usability and simplifying production, storage, and assembly by using symmetrical designs that can be easily adapted to different closing directions without replacing the roller carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If drivers are formed integrally with roller supports or permanently connected thereto, then structural strength is improved, but device complexity and manufacturing cost increase due to requiring separate right- and left-hand designs
Solution Approach 1:
The driver is designed with asymmetric geometry that allows it to function in both orientations. The driver has a specific shape with a head portion and a body portion that creates functional asymmetry, enabling it to engage with the roller support in either right-hand or left-hand configuration without requiring different designs.
Solution Approach 2:
The driver is designed as a universal component that can serve both right-hand and left-hand applications. By making the driver capable of functioning in both orientations through its asymmetric geometry and reversible attachment mechanism, a single design replaces the need for separate right- and left-hand drivers, reducing device complexity while maintaining structural strength.
2Adaptability or versatility
If separate right- and left-hand roller carrier designs are used, then functional requirements are met, but manufacturing cost and storage requirements increase
Solution Approach 1:
The driver is designed as a universal component that can serve both right-hand and left-hand applications. By making the driver capable of functioning in both orientations through its asymmetric geometry and reversible attachment mechanism, a single design replaces the need for separate right- and left-hand drivers, reducing manufacturing cost and storage requirements while maintaining functional adaptability.
3Reliability
If the entire roller carrier must be replaced to change closing direction, then reliability is maintained, but loss of time and productivity decrease
Solution Approach 1:
The driver is designed as a separable component that can be independently removed and reattached to the roller support. This segmentation allows the driver to be detached and rotated to a different orientation without affecting the roller support or other components, enabling quick direction changes while maintaining system reliability through proven component integrity.
Solution Approach 2:
The driver attachment system is designed to be dynamically reconfigurable, allowing the driver to be easily detached, rotated, and reattached in different orientations. This dynamic capability enables the system to adapt to different closing directions without requiring complete roller carrier replacement, reducing downtime while maintaining reliability.
4Strength
If drivers are permanently connected to roller supports, then structural integrity is improved, but ease of operation and adaptability worsen
Solution Approach 1:
The driver is designed as a separable component that can be independently removed and reattached to the roller support. This segmentation maintains structural integrity when assembled while enabling easy reconfiguration for different operating directions, resolving the contradiction between permanent connection strength and adaptability.
Solution Approach 2:
The driver is pre-designed with asymmetric geometry and attachment features that facilitate easy removal and reattachment in different orientations. This preliminary design consideration enables quick adaptation without compromising structural integrity, as the connection mechanism is inherently designed for both strength and reconfigurability.

AI summary
In a device for closing building openings, in particular sliding doors or windows, etc., with several sliding leaves (2, 3, 4), each having a carriage (7) guided on a track (5), which are provided with drivers (10) at their ends facing each adjacent sliding leaf for mutual engagement at least in the closing direction, wherein the carriage (7) is provided on the track side with roller carriers (13) for each roller (8) assigned to the leaf ends and containing a driver (10), the need for differently designed roller carriers (13) can be avoided by designing the driver (10) as a separate part from the assigned roller carrier (13), which is symmetrical to its central transverse plane and can be attached to the assigned roller carrier (13) by means of a holding device that is symmetrical to the central longitudinal plane of the roller carrier (13).
