Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for connecting means with polygonal heads are prone to unintentional loosening, posing safety risks due to the potential for serious injuries from the size and weight of the devices if the connection is released.
Innovation Solution
A flexible securing means that runs circumferentially along the fixing device, with reversible connections at both ends, is integrated to prevent unintentional detachment from flanges or similar connecting parts, utilizing a chain design with spacers and neodymium magnets for secure attachment, and a quick-release fastener for easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a chain fixing device with reversible connecting elements is used to secure flanges, then the ease of operation for joining and separating flanges is improved, but the reliability against unintentional loosening deteriorates
Solution Approach 1:
A flexible locking element in the form of a strap or chain runs circumferentially along the fixing device, providing continuous security against loosening while allowing easy reversible connection at the ends through a locking mechanism
Solution Approach 2:
The fixing device is divided into modular chain links that can be easily connected and disconnected, while the flexible locking element provides continuous circumferential security throughout the entire structure
2Strength
If the fixing device is made with larger size and weight to secure flanges more firmly, then the strength of connection is improved, but the harmful factors such as safety risks from potential injuries worsen
Solution Approach 1:
The flexible locking element distributes the securing force circumferentially along the entire fixing device, providing strong connection through distributed pressure rather than concentrated heavy components
Solution Approach 2:
The circumferential arrangement of the flexible locking element follows the curved contour of the fixing device, optimizing the distribution of securing forces around the flange connection
