Self-Locking Hook Connection Assembly for Secure Tension Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook connection systems, such as rigging plates and connecting hooks, face challenges in securely attaching objects or tensioning devices under tensile forces without additional locking mechanisms, especially when subjected to mechanical stress.
Innovation Solution
A hook connection unit comprising two hook connection parts that form a closed-edge hook eyelet when stacked, allowing secure attachment of objects or tensioning devices, with a self-locking mechanism activated by tensile forces, and featuring a Y- or T-shaped design with aligned attachment and connection eyes for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hook connection part uses an open edge opening for inserting tensioning devices, then ease of operation is improved, but reliability deteriorates under tensile forces
Solution Approach 1:
The edge opening transitions from an open state during insertion to a closed state under tensile force. The hook connection part dynamically changes its configuration based on the applied load, being open for ease of insertion and automatically closing to provide security under tension.
Solution Approach 2:
The hook connection part automatically closes the edge opening when subjected to tensile forces without requiring external intervention. The design enables the component to self-lock through the action of the tensioning device itself, eliminating the need for separate locking mechanisms.
2Reliability
If additional locking mechanisms are added to secure attachment under tension, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking function is merged with the basic hook structure. The edge opening and the hook body are integrated into a single component, where the hook's geometry itself provides the locking action when closed, eliminating the need for separate locking mechanisms.
Solution Approach 2:
The hook connection part automatically closes the edge opening when subjected to tensile forces without requiring external intervention. The design enables the component to self-lock through the action of the tensioning device itself, eliminating the need for separate locking mechanisms.
3Reliability
If the hook connection part is designed for self-locking under tension, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The edge opening transitions from an open state during insertion to a closed state under tensile force. The hook connection part dynamically changes its configuration based on the applied load, being open for ease of insertion and automatically closing to provide security under tension.

AI summary
The invention relates to a hook connection assembly (3). The hook connection assembly (3) comprises a traction element (16) and a hook connection unit (2). The hook connection unit (2) has two identical hook connection parts (1a, 1b) which are rotated 180° about a longitudinal axis (4) and rest against each other. The hook connection parts (1a, 1b) form a closed-edge hook eye (15). The hook connection parts (1a, 1b) each have connecting eyelets (8) and stop eyelets (9, 10) through which the traction element (16) is threaded. The hook connection assembly (3) can provide a self-locking connection. The hook connection assembly (3) is used, for example, in outdoor applications, particularly for climbing belays, camping, bicycles, or backpacks and bags.
