End-Face Hinge Integration for Collision-Free Furniture Door Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges with integrated linear and pivot guides protrude into the furniture body, limiting the free design of the interior and causing collisions with adjacent furniture parts during opening and closing.
Innovation Solution
A furniture board with an integrated or inserted hinge where the linear guide and pivot guide are positioned between two parallel planes defined by the side surfaces of the board, ensuring that hinge components remain within the board's surface, allowing for a combined lifting and pivoting movement without protrusions, and incorporating a damping device and adjusting mechanism for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the linear guide and pivot guide are integrated into the furniture board, then the hinge takes up less space inside the furniture body, but the guide levers still protrude into the body requiring openings in the side wall
Solution Approach 1:
The patent repositions the hinge mechanism from a lateral integration (side wall mounting) to an end-face integration. By moving the linear guide and pivot guide to the end face of the furniture board, the guide levers can be contained within the board's thickness dimension rather than protruding laterally into the furniture body. This dimensional shift allows the hinge to remain compact while eliminating the need for openings in the side walls.
2Ease of operation
If the hinge components protrude into the furniture body, then the hinge can achieve combined lifting and pivoting movement, but it hinders the free design of the interior and causes collisions with adjacent furniture parts
Solution Approach 1:
The patent extracts the protruding guide levers from the furniture body interior by repositioning them to the end face of the board. This extraction removes the harmful protrusion that caused collisions with adjacent furniture parts while preserving the essential lifting and pivoting functions. The guide levers are taken out from the problematic lateral position and relocated to a non-intrusive end-face position.
3Ease of operation
If the hinge is designed with traditional mounting on inner side wall, then the door can be guided by mounted hinges, but it requires additional mounting plates or hinge cups that increase device complexity
Solution Approach 1:
The patent merges the hinge components (linear guide, pivot guide, and guide levers) directly into the furniture board structure at the end face. This integration eliminates the need for separate mounting plates or hinge cups, as the board itself becomes the mounting substrate. The merging of these previously separate components into a unified end-face integration reduces the overall device complexity while maintaining the door guidance function.

AI summary
A furniture board includes an integrated or inserted hinge for guiding a movable furniture part. The furniture board has two side faces, an end face, and an end-face recess for receiving a hinge. The hinge includes a basic element, a linear guide and a pivot guide hinged thereto. The linear guide has forcibly guided movable elements, to which the pivot guide is hinged at a distance from the basic element. Two side faces of the furniture board lie one in a first and one in a second plane. The linear guide and the hinged connection of the pivot guide to the linear guide lie between the first and the second plane, at least in a closed state of the hinge.
