Connection fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection fittings for plate-shaped furniture parts, such as partition walls and movable screens, either require tools for assembly and disassembly or lack stability in angle adjustment, leading to unintended changes in the angle between connected components.
Innovation Solution
A connection fitting system comprising a mounting base, a pivotable locking arm with a recess and a fixing pin, allowing for adjustable and secure attachment of two plate-shaped furniture parts without tools, enabling stable and variable angle adjustments between connected components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If angled elements with fixation screws are used to connect partition walls, then a stable connection is achieved, but tools are required for assembly and disassembly and the angle cannot be adjusted
Solution Approach 1:
The connection fitting is divided into separate components: a mounting base portion that attaches to the furniture part, and a locking arm with a fixing means that can be independently manipulated. This segmentation allows the locking arm to be operated without tools while the mounting base provides stable attachment.
Solution Approach 2:
The locking arm is designed to be pivotable about a rotation axis, enabling dynamic adjustment of the connection angle. The fixing means can be moved in radial direction to lock at different angular positions, providing both stability and adjustability.
2Adaptability or versatility
If hook-and-loop connections are used to allow arbitrary angle adjustment, then angle variability is achieved, but connection stability is lost and inadvertent release occurs
Solution Approach 1:
The locking arm can be rotated to different angular positions to achieve arbitrary angle adjustments between furniture parts. The pivotable design allows continuous angle variation while maintaining a stable locked position at each setting.
Solution Approach 2:
The fixing means acts as an intermediary between the locking arm and the mounting base portion. It provides a positive locking mechanism that prevents inadvertent release while allowing intentional adjustment by moving the fixing means in radial direction.
3Reliability
If angled elements are used to connect furniture parts, then a fixed predetermined angle is achieved, but replacement of the angled element is required for angle variation
Solution Approach 1:
The locking arm is designed to be pivotable about a rotation axis, enabling dynamic adjustment of the connection angle. The fixing means can be moved in radial direction to lock at different angular positions, providing both stability and adjustability.
Solution Approach 2:
The connection fitting serves multiple functions: it provides stable attachment through the mounting base portion, enables angle adjustment through the pivotable locking arm, and allows locking at various positions through the movable fixing means. This multi-functionality eliminates the need for different angled elements for different angles.

AI summary
A connection fitting is provided for releasably attaching a first plate-shaped furniture part at a second plate-shaped furniture part. The connection fitting comprises a mounting base portion for attaching the connection fitting at one of the two furniture parts, a locking arm with a first end portion and a second end portion facing the first end portion, and a fixing means. The locking arm at the first end portion is arranged pivotably about a rotation axis (DA) at the mounting portion, and the fixing means is arranged at the second end portion of the locking arm such that it is movable in radial direction relative to the locking arm. Further, a connection fitting system with at least two connection fittings and a furniture part with a connection fitting are provided.
