Interlocking Pipe Clip Structure to Prevent Accidental Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe fasteners often unintentionally detach from each other when attempting to remove a pipe, leading to instability in securing pipes parallel to a fastening base.
Innovation Solution
A pipe fastener design featuring identical connecting and counter-connecting devices that engage in a form-fitting manner, allowing for rigid connection and release through a pivoting motion, eliminating the need for rotational disconnection and ensuring secure attachment to a fastening base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a laterally protruding hook and recess connection is used to join pipe clips, then the pipe clips can be connected in a straight row, but the connection can be inadvertently released when attempting to unclip a pipe
Solution Approach 1:
The connecting device features an L-shaped finger that engages with an undercut in a specific orientation. The asymmetric geometry of the L-shaped finger relative to the undercut creates a directional engagement where the finger can slide into the undercut during connection but cannot disengage without a deliberate pivoting motion. This asymmetric design prevents inadvertent release while maintaining ease of connection.
2Strength
If a bayonet lock-style connecting device is used, then rigid connection is achieved, but the release mechanism requires complex rotational movement
Solution Approach 1:
Instead of requiring a complex multi-rotation bayonet lock mechanism to release the connection, the invention inverts the approach by designing a simple single-pivot motion that disengages the L-shaped finger from the undercut. The release mechanism is simpler than the engagement mechanism, allowing easy operational release while maintaining strong connected state through the geometric interlocking of the finger and undercut.

AI summary
The invention proposes to form a pipe clip (2) with identical L-shaped fingers (8) as connecting devices (13) on opposite sides (7), which can be connected by pivoting with pipe clips (2) whose sides (7) are abutting each other, so that a series of pipe clips (2) can be formed, of which only every second, third or fifth has to be screwed onto, for example, a wall or ceiling.
