Improvements to a hidden device for the wall assembly of a piece of furniture and structural component of a piece of furniture comprising said device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hidden hanging brackets for furniture assembly face difficulties in actuation and regulation due to their installation position within the furniture shoulder, particularly when the cupboard is close to the wall, limiting tool accessibility and requiring different configurations for left or right shoulders.
Innovation Solution
A shoulder-centre hanging bracket with a movable hooking arm and dual regulation mechanisms, featuring radially engaged screw control elements with toothed crowns and imprints, allowing activation from multiple sides, enabling independent height and depth adjustments regardless of the shoulder's position or obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hanging bracket is installed in the housing of the shoulder, then it provides hidden assembly function, but it limits tool accessibility for actuation and regulation
Solution Approach 1:
The control element is segmented into two functional parts: a screw mechanism for depth regulation and a toothed crown for height regulation. This segmentation allows each control element to be actuated independently from different sides, resolving the accessibility problem without requiring multiple device configurations
Solution Approach 2:
The control element serves multiple functions: it regulates both depth and height of the arm, and can be actuated from multiple sides (front, rear, left, right) depending on installation position. This multi-functionality eliminates the need for different device configurations for left or right shoulders
2Ease of operation
If the cupboard is close to the wall, then it achieves compact assembly, but it hinders the manoeuvring of the tool for actuation
Solution Approach 1:
The toothed crown extends radially from the screw axis, creating a new dimension for tool engagement. This allows the tool to approach from multiple directions (front, rear, left, right) rather than being constrained to a single access point, solving the problem of tool manoeuvrability in compact installations
3Adaptability or versatility
If different configurations are used for left or right shoulders, then it ensures proper actuation, but it increases device complexity and reduces versatility
Solution Approach 1:
The control element with radially arranged toothed crown provides universal actuation capability for all shoulder positions (left, right, front, rear). This single design replaces the need for multiple configurations, achieving both adaptability and reduced complexity
Solution Approach 2:
Instead of adapting the device configuration to the shoulder position, the solution inverts the approach by making the control element accessible from all directions. This allows the same device configuration to work for all installation scenarios

AI summary
A hidden device (1) for the wall assembly of a structural component wherein shaped engagement means (15,16) for the assembly tool extend at least on two opposite sides of a respective control element (13,14) of a specific regulation mechanism in height or depth, so as to be activated in correspondence with opposite sides of the body (2); a further object of the invention relates to a structural component of a piece of furniture which comprises said device.
