Fitting Mounting Body Coupling for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture fittings with multiple adjustment devices often suffer from instability and rattling due to three-dimensional play within the assembly, which can lead to undefined movement behavior of pivoting elements.
Innovation Solution
The coupling of two adjustment devices in such a way that adjustments in one direction also result in partial adjustments in the other direction, significantly reducing the play of the bearing body within the base body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional play of the coupling part within the mounting part is provided to enable adjustable coupling, then the coupling part can be adjusted three-dimensionally with respect to the mounting part, but this leads to instability and rattling of the coupling part
Solution Approach 1:
The adjustment mechanism is divided into two independent adjustment devices: a first adjustment device for adjusting in a first direction (e.g., depth adjustment) and a second adjustment device for adjusting in a second direction (e.g., lateral adjustment). This segmentation allows each adjustment device to operate independently in its specific direction, providing necessary adjustability while preventing unwanted movement and instability in other directions.
Solution Approach 2:
Each adjustment device is designed with specific local qualities tailored to its adjustment direction. The first adjustment device has adjustment features optimized for depth adjustment, while the second adjustment device has adjustment features optimized for lateral adjustment. This localized optimization ensures stable adjustment behavior in each specific direction without compromising overall stability.
2Manufacturing precision
If multiple adjustment devices are provided for multi-directional adjustment, then the fitting can achieve precise positioning in multiple directions, but the device complexity increases
Solution Approach 1:
The complex multi-directional adjustment function is segmented into two independent adjustment devices, each responsible for one adjustment direction. This segmentation simplifies the design and manufacturing of each individual adjustment device while achieving the overall goal of precise multi-directional positioning through their combined operation.
Solution Approach 2:
The mounting part is designed with universal adjustment capabilities that can accommodate both the first adjustment device and the second adjustment device. The mounting part structure integrates multiple functions (supporting bearing body, accommodating both adjustment devices, providing adjustment features) into a single component, reducing overall system complexity.

AI summary
The invention relates to a fitting (4) for movably mounting a pivoting element (3), in particular a furniture part (3a), a door or a window, relative to a stationary support (2), comprising: - a first fitting part (6) which is designed to be secured to a preferably substantially horizontally oriented panel (5a-5e) of the support (2), - a second fitting part (7) for securing to the pivoting element (3), said second fitting part (7) being pivotally connected to the first fitting part (6) via at least one articulated lever (8a, 8b), wherein - the first fitting part (6) has at least one main part (12) and at least one mounting body (32) which can be adjusted relative to the main part (12) and on which the at least one articulated lever (8a, 8b) is supported, - a first adjusting device (27) by means of which the at least one mounting body (32) can be adjusted relative to the main part (12) in a first adjustment direction (M1), preferably transversely to an end face (33) of the first fitting part (6), and - at least one second adjusting device (28) by means of which the at least one mounting body (32) can be adjusted relative to the main part (12), preferably substantially parallel to the end face (33) of the first fitting part (6), in a second adjustment direction (M2) which is transverse to the first adjustment direction (M1). The two adjusting devices (27, 28) are coupled together such that the mounting body (32) can also be at least partly moved in the second adjustment direction (M2) when the mounting body (32) is adjusted in the first adjustment direction (M1) by means of the first adjusting device (27).
