Fitting Assembly Connecting Rod Orientation Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacture and assembly of sliding elements, such as sliding doors and windows, are complicated by space restrictions, particularly when the connecting rod needs to be accommodated in a cavity, often requiring cumbersome machining or additional profile elements due to size mismatches.
Innovation Solution
A fitting arrangement with couplings that have two separate attachment sections allowing the connecting rod to be attached in different orientations relative to a stationary reference plane, enabling flexible mounting either parallel or transverse to the wing plane, thus simplifying assembly and reducing component storage costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connecting rod is accommodated in a cavity formed in a profile element, then the assembly is compact, but the profile element requires cumbersome machining or additional profile elements when the connecting rod is too wide
Solution Approach 1:
The coupling is divided into two separate attachment sections (first and second attachment sections) that are spatially separated. This segmentation allows the connecting rod to be attached in different orientations without requiring complex machining of the profile element, as each attachment section can independently accommodate the rod in its respective orientation.
Solution Approach 2:
The coupling is designed with multi-functionality by incorporating two attachment sections that can each accommodate the connecting rod in different orientations. This universal design allows the same coupling component to serve multiple mounting configurations, eliminating the need for custom-machined profile elements for different orientations.
2Adaptability or versatility
If different profile elements are provided for different orientations of the connecting rod, then the assembly can accommodate various orientations, but the device complexity and storage costs increase
Solution Approach 1:
A single coupling component incorporates two attachment sections that provide multiple mounting orientations, eliminating the need for different profile elements for different orientations. This universal design reduces component variety while maintaining adaptability.
Solution Approach 2:
Two separate attachment functions are merged into a single coupling component. Instead of using separate profile elements for different orientations, both attachment sections are integrated into one coupling, reducing the number of components needed and simplifying storage and assembly.
3Ease of manufacture
If the connecting rod is attached in a fixed orientation, then the assembly is simple, but the adaptability to different assembly situations is reduced
Solution Approach 1:
The coupling design allows for dynamic selection of mounting orientation through its two attachment sections. While each individual attachment section provides a fixed attachment point, the overall coupling system is dynamic in that it can adapt to different assembly situations by selecting which attachment section to use, providing flexibility without complicating the individual attachment mechanisms.

AI summary
The invention relates to a fitting assembly for a sliding element which comprises a displaceable leaf/sash, having at least two carriages and a connecting rod for coupling the carriages to one another, wherein the connecting rod has a flattened cross section and thereby defines a main plane of extent, and wherein at least one of the carriages has arranged thereon a coupling for mounting the connecting rod on the carriage. The coupling has two separate fastening portions to which the connecting rod can be selectively fastened, wherein the fastening portions are configured in such a way that the main plane of extent of the connecting rod has different orientations relative to a positionally fixed reference plane depending on which of the separate fastening portions the connecting rod is fastened to.
