Wall Cabinet Fitting With Support Element for Damage-Free Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During height adjustment of wall-mounted furniture pieces, unwanted contact with the wall can occur, leading to potential damage to both the furniture and the wall.
Innovation Solution
A fitting system with a length-adjustable drive unit and a support element, such as a rolling or sliding element, is used to prevent contact between the furniture and the wall, allowing for vertical adjustment while minimizing friction and enabling tilt adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wall-mounted furniture piece is adjusted vertically to change height, then the mounting height is variable and suitable for different users, but unwanted contact with the wall occurs causing damage
Solution Approach 1:
A support element is introduced as an intermediary component between the furniture piece and the wall. This support element acts as a mediator that prevents direct contact between the furniture and the wall during vertical adjustment, thereby eliminating damage while preserving height adjustability.
Solution Approach 2:
The support element is positioned in advance between the furniture piece and the wall to provide protective cushioning before any contact can occur. This preventive measure ensures that even during extreme vertical adjustment positions, the furniture and wall remain separated, preventing damage beforehand.
2Object-affected harmful factors
If a support element is introduced to prevent contact, then damage is prevented, but the device complexity increases
Solution Approach 1:
The support element is applied locally only at the specific contact point between the furniture piece and the wall, rather than throughout the entire structure. This localized approach provides the necessary protection while minimizing the addition of components and maintaining overall structural simplicity.
Solution Approach 2:
The support element is designed as a simple, inexpensive component that can be easily replaced if needed. This approach keeps the overall device complexity low by using a basic protective element rather than a complex mechanical system.
3Ease of operation
If the support element is designed as a rolling element, then friction is reduced for smooth movement, but the manufacturing precision requirements increase
Solution Approach 1:
The rolling element is designed as a simple, inexpensive component with basic geometric features that can be manufactured using standard machining processes. This approach achieves the desired low-friction movement while avoiding the need for high-precision manufacturing that would be required for more complex rolling element designs.
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 system effectively prevents damage by allowing smooth height adjustment and tilt of wall-mounted furniture pieces, ensuring safe and secure mounting without harming the wall or the furniture.
Implementation Method 1
the support element is designed as a sliding element or rolling element, in particular as a rolling element. This enables a low-friction movement of the wall-mounted furniture piece to adjust its height.
Implementation Method 2
the support element is designed as a sliding element or rolling element, in particular as a rolling element. This enables a low-friction movement of the wall-mounted furniture piece to adjust its height.

AI summary
A fitting for securing a wall-mounted furniture piece, in particular a wall-mounted cabinet, on a wall is provided. The wall-mounted furniture piece has a furniture body with at least one base, a lateral wall, and a rear wall. The fitting has a first fitting part that can be secured to the wall, a second fitting part that can be secured to the wall-mounted furniture piece, and a drive unit having an adjustable length and via which the first fitting part and the second fitting part are interconnected. A support element is arranged between the first fitting part and the rear wall or a contact surface situated towards the rear of a wall-mounted furniture piece.
