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

VSEngineering 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

Engineering Contradiction:
Improvetool accessibilityVSAvoiddevice configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvetool manoeuvrabilityVSAvoidinstallation position adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveshoulder position adaptabilityVSAvoiddevice configuration variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #13The other way round (Inversion)

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.
