Wall Cupboard Holder with Shear-Resistant Flanges for Loaded Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall cupboard holders, particularly those with plastic box-shaped bodies, fail to provide effective and safe anchoring due to shear forces when cupboards are loaded, leading to instability and potential falls or breaks.
Innovation Solution
A visible adjustable wall cupboard holder group with a hooking element, regulation mechanisms for depth and height, and side flanges with shear-resistant elements that protrude from the central portion, ensuring stable positioning through screws or expansion pegs with gripping teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional plastic box-shaped wall cupboard holders are used, then the assembly is simple and the structure is compact, but the holder cannot resist shear forces effectively when the cupboard is loaded
Solution Approach 1:
The holder is divided into a central portion and two side flanges, with the shear-resistant elements located on the side flanges. This segmentation allows the holder to resist shear forces through the side flanges while maintaining a compact central portion for simple assembly.
Solution Approach 2:
The invention introduces shear-resistant elements that protrude from the side flanges in a lateral direction, adding a new dimensional aspect to the holder structure. This allows the holder to resist shear forces through lateral protrusions rather than relying solely on the main body structure.
2Stability of the object's composition
If the cupboard thickness is reduced to meet modern design trends, then the cupboard becomes more sleek and modern, but the coupling between cupboard and holder becomes less effective and safe
Solution Approach 1:
The shear-resistant elements are designed to protrude from the side flanges and engage with the cupboard panel in advance, creating preliminary mechanical interlocking that prevents misalignment before the cupboard is fully loaded. This preliminary action ensures stability even with thinner panels.
Solution Approach 2:
The side flanges with shear-resistant elements act as intermediary structures between the holder body and the cupboard panel. These intermediaries provide additional anchoring points that enhance the coupling stability without requiring thicker cupboard panels.
3Reliability
If the holder is designed to resist high shear forces, then the coupling becomes safe and durable, but the assembly becomes more complex and difficult to install
Solution Approach 1:
The shear-resistant elements are integrated into the side flanges of the holder body, merging the shear-resistance function with the existing structural components. This integration allows the holder to resist high shear forces while maintaining a unified structure that is relatively simple to assemble.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a firm and easy assembly on any type of wall cupboard, effectively resisting shear forces and preventing misalignment or falls, even when the cupboard is loaded, by using shear-resistant elements that collaborate with fixing means like screws or pegs for stable positioning.
Implementation Method 1
expansion pegs with gripping teeth, which are inserted in holes (41) situated in the internal side wall (12) of the wall cupboard (11), for a stable positioning of the wall cupboard holder group (10) on the internal wall (12) of the wall cupboard (11)

AI summary
An adjustable wall cupboard holder group (10) for anchoring a cupboard (11) to the wall having a hook (15) situated at the free end of a hooking element (14) extending externally from the wall cupboard holder group. A regulation mechanism of the positions in depth and height of the hook (15) is associated with the hooking element (14). The wall cupboard holder group includes a central section or portion (16) containing the hooking element (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, where at least the other section includes at least one fixing device (19, 19′).
