Concealed Furniture Panel Joint Without Base Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joining devices for furniture parts, such as shoulders and bases, are aesthetically unpleasing due to visible holes and protrusions, and can weaken the base due to intersecting holes, making them prone to breakage and obstructing the surface.
Innovation Solution
A joining device with a blocking group inserted inside a seat within the thickness of the shoulder, using a pin connection group assembled in the base, which is activated by a tool to create a stable and invisible coupling without visible holes or protrusions on the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holes are provided in the base for the joining device, then the joining function is achieved, but the base is weakened and becomes prone to breakage
Solution Approach 1:
The invention relocates the blocking group from the base to the shoulder, changing the spatial dimension of the joining mechanism. The blocking group is now positioned in a vertical hole in the shoulder rather than requiring holes in the base, thus achieving the joining function without compromising base strength.
2Reliability
If holes and closing caps are used in the base, then the joining device functions, but the aesthetic appearance is degraded and the surface is obstructed
Solution Approach 1:
The invention extracts the blocking group from the base and relocates it to the shoulder. This removes the need for visible holes and closing caps in the base surface, eliminating the aesthetic degradation and surface obstruction while maintaining the joining function through the shoulder-mounted blocking group.
3Ease of manufacture
If multiple intersecting holes are made in the base, then the joining device is assembled, but the base structure is weakened
Solution Approach 1:
The invention moves the blocking group to the shoulder, changing the assembly dimension from base-centered to shoulder-centered. This allows the blocking group to be positioned in a vertical hole in the shoulder that intersects with horizontal holes, achieving easy assembly without requiring multiple intersecting holes in the base that would weaken its structure.

AI summary
A joining device with minimum visibility for parts of furniture and furnishing items, in particular connecting a first panel to a second panel, which must be moved towards each other in an approach direction to bring the edge of one panel buffered in a tightening position against a surface of the other panel, includes a blocking group and a connection group assembled on the panels. The blocking group is inserted inside a seat contained in the thickness of the panel on which the blocking group is applied, and the seat has a longitudinal axis perpendicular to the approach direction, and extending from an edge towards the inside of the panels.
