Adjustable Wall Cupboard Holder With Shear-Resistant Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall cupboard holders fail to provide effective, long-lasting, and safe anchoring to walls, especially when subjected to shear forces due to reduced panel thicknesses and increased loading, leading to instability and potential falls or breaks.
Innovation Solution
A visible wall cupboard holder group with adjustable hook positioning and side flanges equipped with shear-resistant elements, such as plugs or expansion pegs, for secure attachment to the cupboard's shoulder and wall support, ensuring stability under load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wall cupboard holders use box-shaped plastic bodies with screw or plug fixation, then assembly is simplified, but the coupling cannot resist high shear forces when the cupboard is loaded
Solution Approach 1:
The wall cupboard holder is divided into two separate components: a plate element for mounting to the wall and a hook element for supporting the cupboard. This segmentation allows each component to be optimized independently - the plate element can have large surface area and multiple fixation points for wall attachment, while the hook element can be designed specifically to bear shear loads from the cupboard weight.
Solution Approach 2:
The invention transitions from a single integrated holder to a two-element system where the plate element provides a large mounting surface area dimension that is separate from the hook element's load-bearing function. This dimensional separation allows the plate to distribute fixation forces across the wall while the hook handles the shear forces from the cupboard.
2Adaptability or versatility
If panel thicknesses are reduced to meet design trends, then furniture modernization is achieved, but the stability of wall cupboard coupling deteriorates
Solution Approach 1:
By separating the mounting function (plate element) from the load-bearing function (hook element), the invention compensates for reduced panel thickness. The plate element can be firmly anchored to the wall independently of the thin cupboard panels, while the hook element connects to the cupboard, distributing stresses in a way that does not rely on thick panels.
Solution Approach 2:
The plate element acts as an intermediary between the wall and the hook element. It provides a stable mounting base on the wall that is independent of the cupboard panel thickness, allowing the hook to be positioned and loaded without compromising stability due to thin panels.
3Adaptability or versatility
If cupboards are frequently overloaded, then utility is increased, but the coupling effectiveness and safety of wall cupboard holders deteriorates
Solution Approach 1:
The separation into plate and hook elements allows the hook to be specifically designed for high load-bearing capacity while the plate provides stable wall attachment. The hook can be made from high-strength material with appropriate geometry to handle overloading conditions, while the plate ensures the mounting point remains stable on the wall.
Solution Approach 2:
The plate element is pre-mounted to the wall with appropriate fixation (screws, anchors) to establish a secure base before the hook and cupboard are attached. This preliminary action ensures that the wall mounting can withstand high loads before the cupboard is placed, preventing coupling failure under overload conditions.

AI summary
An adjustable wall cupboard holder group (10) for anchoring a cupboard (11) to the wall comprises a hook (15) situated at the free end of a hooking element or arm (14) extending externally from said wall cupboard holder group. A regulation mechanism of the positions in depth and height of said hook (15) is associated with said arm (14). Said wall cupboard holder group comprises a central section or portion (16) containing said arm (14) and mechanism, and two side sections or flanges (18, 18'), at least one element (20, 20') resistant to shear forces, protruding from at least one of said sections, whereas at least the other section comprising at least one fixing device (19, 19').
