Pivoting Locking Arm Connection Fitting for Tool-Free Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection fittings for panel-shaped furniture parts, such as partitions, either require tools for detachment and reconnection or provide unstable angles due to the use of angle elements or Velcro fasteners, limiting flexibility and stability in adjusting the angle between connected partitions.
Innovation Solution
A connecting fitting system comprising a mounting base section, a pivotable locking arm with a locking pin, and a recess, allowing for 180° pivoting and radial movement of the locking pin, enabling tool-free and stable attachment and detachment of furniture parts with adjustable angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If angle elements with fastening screws are used to connect partitions, then a stable connection at a predetermined angle is achieved, but the partitions cannot be detached and reconnected without tools
Solution Approach 1:
The connection fitting is divided into separate components: a mounting base section that attaches to the furniture part and a locking arm with locking means that can engage with a recess. This segmentation allows the locking arm to be pivoted into position and locked without tools, while still providing a stable connection when engaged.
Solution Approach 2:
The locking arm is designed to be pivotable about an axis of rotation, transitioning between locked and unlocked positions. The locking means can move radially to engage or disengage from the recess, enabling tool-free operation while maintaining connection stability when locked.
2Adaptability or versatility
If Velcro fasteners are used to attach partitions, then the partitions can be connected at any angle and the angle can be changed, but the connection is not stable and may loosen unintentionally
Solution Approach 1:
The locking arm can be pivoted to different angular positions to accommodate various angles between partitions, providing adaptability. When the desired angle is achieved, the locking means engages with the recess to secure the connection, preventing unintentional loosening while maintaining angle adjustability.
Solution Approach 2:
The system allows changing the angular parameter between partitions by pivoting the locking arm to different positions. The locking means can engage at any angular position, providing both angle variability and connection stability without the reliability issues of Velcro fasteners.
3Reliability
If angle elements are used to connect partitions at a predetermined angle, then connection stability is achieved, but changing the angle requires exchanging the angle element
Solution Approach 1:
The locking arm is designed to be pivotable about an axis of rotation, allowing it to be repositioned to different angular positions without replacing any components. This enables angle changes by simply pivoting the locking arm, eliminating the time-consuming process of exchanging angle elements while maintaining connection stability through the locking means.
