Pivoting Lockable Connecting Ring for Multi-Direction Rope Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting rings for safety equipment are inconvenient to use as they require ropes or safety harnesses to be sewn into a loop before connection, limiting their usage scenarios and making it difficult to connect additional ropes or harnesses in different directions.
Innovation Solution
A lockable connecting ring formed by two pivotally and threadedly connected components, allowing for adjustable insertion and secure connection of ropes or safety harnesses in various directions, with a mechanism for easy opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional integral connecting ring is used, then the structure is simple and strong, but the ropes or safety harnesses can only be sewn to form a loop for fixation after insertion, making it difficult to connect additional ropes or harnesses in different directions
Solution Approach 1:
The connecting ring is divided into two separate components: a first component with a first rod body and a second component with a second rod body. These components can be independently manipulated and connected through pivotal and threaded connections, enabling the ring to be opened and closed while maintaining structural integrity. This segmentation allows ropes to be inserted without pre-forming loops while preserving connection strength.
Solution Approach 2:
The connecting ring transitions from a static integral structure to a dynamic assembly that can be opened and closed. The pivotal connection between components allows the ring to change its configuration state, enabling insertion of ropes in various configurations and directions, then securing them through threaded fastening.
2Ease of operation
If ropes or safety harnesses are sewn to form a loop for fixation in a conventional connecting ring, then the connection is secure, but the operation becomes inconvenient and additional ropes or harnesses cannot be easily connected
Solution Approach 1:
By separating the connecting ring into two components that can be independently opened and closed, the system allows ropes to be inserted without pre-sewing loops. The threaded connection mechanism provides secure fixation equivalent to or exceeding traditional sewn loops, while dramatically improving ease of operation and enabling connection of multiple ropes in different directions.
Solution Approach 2:
The threaded fastening mechanism acts as an intermediary between the two components, providing a reliable connection method that is both easy to operate and secure. This intermediary mechanism replaces the need for sewing operations while maintaining connection reliability through the threaded engagement between components.
3Ease of operation
If a conventional integral connecting ring is used, then the manufacturing is simple, but the operation is inconvenient as ropes must be sewn into loops before insertion
Solution Approach 1:
The connecting ring is segmented into two manufacturable components that can be produced separately using standard manufacturing processes, then assembled through pivotal and threaded connections. This segmentation improves operational convenience by enabling the ring to be opened and closed, while the manufacturing complexity remains manageable through modular production approaches.
4Adaptability or versatility
If the connecting ring is made as an integral body, then the structural strength is maintained, but the adaptability to different usage scenarios is limited
Solution Approach 1:
The connecting ring is divided into two components connected by pivotal and threaded joints. These connections are designed to maintain structural strength equivalent to or exceeding integral designs, while enabling the ring to be opened and closed for versatile rope insertion in various directions and configurations.
Solution Approach 2:
The two components are pre-configured with pivotal and threaded connection mechanisms that enable easy opening and closing operations. This preliminary design allows users to open the ring for rope insertion in various configurations, then securely close it, providing adaptability without compromising structural integrity.

AI summary
A lockable connecting ring includes a first assembly and a second assembly connected to the first assembly. Two opposite ends of a rod body of the first assembly have a male linking portion and a female lockable portion, respectively. Two opposite ends of a rod body of the second assembly have a male lockable portion and a female linking portion, respectively. The male linking portion is pivotally connected to the female linking portion, and the female lockable portion is detachably connected to the male lockable portion by screwing. When the threaded connection of the lockable connecting ring is unlocked, the lockable connecting ring could be rotated along the pivotal connection to form an opening for allowing the rope to fit around the lockable connecting ring. Then, the female lockable portion is connected to the male lockable portion by screwing again to close the lockable connecting ring, which is convenient for use.
