Polygonal Fastener Locking Chain With Flexible Anti-Detachment Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for fasteners with polygonal heads are prone to unintentional detachment from flanges or similar connecting parts, posing safety risks due to potential uncontrolled movement and injury.
Innovation Solution
A flexible securing means, such as a wire rope, is circumferentially integrated along the fixing device, with adjustable ends that can be releasably connected, ensuring secure attachment to the polygonal heads and preventing unintended detachment by resting against the chain members and spacing components, and utilizing neodymium magnets and quick-release fasteners for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixing device uses a chain with spaced members to attach to polygonal fastener heads, then the fixing device can be installed and removed easily, but the connection between the chain ends is not secured against unintentional detaching
Solution Approach 1:
The fixing device employs a dynamic locking mechanism where the flexible securing means can be easily adjusted and positioned during installation, but automatically locks into a secure state that prevents unintentional detachment. The system transitions from a flexible, easily manipulated state to a locked, secure state through simple operational actions.
Solution Approach 2:
A flexible securing means (such as a wire rope or flexible element) is introduced as an intermediary component between the chain ends. This flexible element can be easily manipulated for installation but provides secure connection when properly positioned, mediating between the ease of operation and reliability requirements.
2Device complexity
If the fixing device is made with a simple chain structure, then the device complexity is reduced, but the fixing device becomes vulnerable to unintentional detachment and safety risks
Solution Approach 1:
The invention merges the simple chain structure with a flexible securing means to create a composite fixing device. The chain provides the basic structural framework while the flexible securing means adds the necessary security feature, combining simplicity with reliability without significantly increasing overall complexity.
Solution Approach 2:
A flexible securing means (wire rope or flexible element) is integrated into the chain structure. This flexible component adds security against detachment while maintaining the overall simplicity of the device. The flexible element can be easily positioned and locked into place without requiring complex mechanical structures.
3Reliability
If a flexible securing means is added to prevent unintentional detachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The flexible securing means is designed as a simple, easily replaceable component that can be quickly installed and removed if needed. This approach prioritizes reliability through a simple additive component rather than integrating complex permanent security mechanisms into the chain structure.

AI summary
A fixing device for fasteners having a polygonal head for the detachable connection of flanges which can be connected to one another and clamped against one another by a screw connection includes a chain which encompasses at least some regions of the lateral surface of the polygonal heads in a form-fitting manner and inhibits the rotation of said fasteners. The chain comprises a plurality of spaced members, each having at least one receptacle, the inner profile of which corresponds to the lateral surface of the polygonal heads. The chain comprises at least one releasable tensioner for detachably joining two ends of the chain. A flexible securing means is provided, which extends circumferentially along the chain, wherein at least two ends of the securing means can be releasably connected to one another.
