Solution Overview
Problem
Hidden hanging brackets for furniture assembly face difficulties in actuation and regulation due to installation position, requiring complex mechanisms and precise manufacturing tolerances, limiting accessibility and increasing production complexity.
Innovation Solution
A shoulder-centre hanging bracket with a box-shaped body featuring multiple radial access holes for direct engagement of a toothed crown by a tool, allowing actuation from various directions, including above and both sides, eliminating the need for pinions and simplifying production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pinions are used to actuate regulation screws, then the device can be actuated from one side, but the manufacturing complexity increases and accessibility is limited
Solution Approach 1:
The patent removes the pinion component from the mechanism, extracting the intermediary element that caused complexity. The regulation screw head is directly exposed through access holes in the body, allowing the tool to engage the toothed crown without requiring a pinion for transmission. This eliminates the pinion-screw engagement interface and simplifies the overall mechanism.
Solution Approach 2:
The body is designed with multiple access holes positioned at different locations (front, rear, sides) that all provide radial access to the toothed crown. This multi-functional access system allows the same regulation mechanism to be actuated from multiple directions, making the device versatile for different installation positions and accessibility requirements.
2Ease of operation
If pinions are positioned in the body to allow side actuation, then regulation is possible, but manufacturing tolerances must be tightly controlled to prevent premature wear or breakage
Solution Approach 1:
The pinion is completely removed from the design. The tool engages directly with the toothed crown on the regulation screw head through access holes, eliminating the intermediate pinion component. This removes the need for precise positioning of a pinion relative to the screw head and eliminates the risk of tooth wear or breakage at the pinion-screw interface.
Solution Approach 2:
The regulation screw head with its toothed crown serves its own actuation function directly, without requiring a separate pinion component. The access holes in the body provide the necessary pathway for the tool to reach and engage the screw head, allowing the screw to be actuated from various positions without complex positioning requirements.
3Adaptability or versatility
If the device is installed in the thickness of a shoulder, then it provides hidden assembly, but accessibility for tool maneuvering is hindered
Solution Approach 1:
The patent provides access to the regulation mechanism through multiple spatial dimensions by positioning access holes at different locations on the body (front, rear, and sides). This multi-directional access system allows the tool to reach the toothed crown from various angles and directions, overcoming the accessibility limitations imposed by the hidden installation position within the shoulder thickness.

AI summary
A hidden device (20) for the wall assembly of a structural component (21) of a piece of furniture, comprising a box-shaped body (22) which houses a first (27) and second (28) regulation mechanism, in height and depth respectively, provided with a first (33) and second regulation screw (46), respectively, each having a head (35,49) comprising a toothed crown. According to the invention, the box-shaped body (22) comprises, for each screw (33,46), at least one access hole (91,92,93,95,96,97) which develops radially with respect to the toothed crown and ends in correspondence with the same, so that the toothed crown is suitable for allowing a direct radial engagement with a tool (U).
