Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of built-in cupboards is complex due to limited accessibility of assembly means and aligning the user-accessible front with the surrounding wall surface, making it difficult to install correctly.
Innovation Solution
A built-in cupboard arrangement featuring stationary bearing braces with adjustably mounted fastening elements having stop and clamping surfaces, allowing for easy alignment and secure mounting by a clamping screw that displaces the cupboard relative to the fastening elements, facilitating simple and accurate installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional mounting hardware is used for built-in cabinets, then the cabinet can be installed in wall niches, but the assembly process becomes very complex due to limited accessibility of assembly means
Solution Approach 1:
The mounting system is divided into separate functional components: bearing struts that provide structural support, fastening elements that enable adjustment and positioning, and clamping screws that secure the cabinet. This segmentation allows each component to be optimized independently and simplifies the overall assembly process by allowing parts to be installed in a logical sequence rather than requiring complex simultaneous alignment.
Solution Approach 2:
The fastening elements are designed to be adjustable on the bearing struts, allowing their positions to be modified during installation. This dynamic adjustment capability enables installers to adapt to varying wall niche dimensions and alignment requirements, significantly reducing assembly complexity while maintaining secure mounting.
2Ease of operation
If the front of the built-in cabinet is aligned with the wall surface, then user accessibility is improved, but the installation becomes more difficult due to precision alignment requirements
Solution Approach 1:
The bearing struts are pre-installed on the wall surface at the desired final position of the cabinet front. This preliminary action establishes the correct alignment reference before the cabinet is mounted, eliminating the need for complex post-installation adjustments and ensuring the cabinet front aligns perfectly with the wall surface for optimal user accessibility.
Solution Approach 2:
The fastening elements act as intermediaries between the cabinet and the bearing struts, providing adjustable positioning that facilitates precise alignment. By allowing the fastening elements to be moved along the bearing struts, the system enables easy adjustment of the cabinet's horizontal and vertical position to achieve perfect alignment with the wall surface.

AI summary
A built-in cabinet arrangement (1) comprises at least two fixed and spaced-apart bearing struts (2) which laterally define a receiving space (3) between the bearing struts (2), at least one fastening element (4) adjustable on each of the bearing struts (2) with a front-facing stop surface (5) and a rear-facing clamping surface (6), and a built-in cabinet (7) that can be inserted into the receiving space (3) between the bearing struts (2) with at least one stop surface (8) which can be brought into contact with the stop surface (5) of the fastening elements (4), and with at least one threaded opening (9) with a clamping screw (10) mounted therein, the screw tip (11) of which acts on the clamping surface (6) of the fastening element (4), wherein the stop surfaces (5) of the fastening elements (4) define a bearing plane (E), and wherein the clamping surface (6) is oriented at an angle (α) to the bearing plane (E).such that when the clamping screw (10) is actuated, the built-in cabinet (7) is displaced relative to the fastening element (4), and the stop surface (8) of the built-in cabinet (7) is moved onto the stop surfaces (5) of the fastening elements (4) such that the stop surfaces (5, 8) can be brought into contact with each other, whereby when the clamping screw (10) is actuated further, the built-in cabinet (7) is clamped against the fastening element (4).
