Rotatable Carabiner Connecting Device Prevents Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carabiner connecting devices often result in entanglement and excessive force transfer when handling multiple items, such as dog leashes or during mountain climbing, due to limited freedom of movement and entanglement of connected items.
Innovation Solution
A connecting device with rotatable and tiltable connection parts, including concave sockets and convex bodies, allows for a high degree of freedom and prevents entanglement by providing a secure yet detachable coupling system between the base member and carabiners, enabling 360° rotation and tilt angles up to 20°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carabiner is connected to a hand grip using a fixed connection, then the connection is stable and secure, but the items connected become entangled and forces are transferred excessively to the user's hand
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connection into a rotatable connection. The connection device includes a rotatable body that can rotate 360 degrees around the carabiner, allowing the connected items to move freely and prevent entanglement while maintaining secure connection. This dynamic capability resolves the contradiction between connection stability and entanglement prevention.
2Adaptability or versatility
If multiple items are connected to a single carabiner, then the user can handle multiple items, but the items easily become entangled
Solution Approach 1:
The patent applies segmentation by providing multiple independent rotatable connection devices, each connected to the base member through its own rotatable body. This allows multiple items to be connected simultaneously while each item can rotate independently, preventing entanglement between items while maintaining the ability to handle multiple items concurrently.
3Reliability
If a fixed connection is used between the carabiner and base member, then the connection is secure, but the user experiences large forces on their hand and reduced freedom of movement
Solution Approach 1:
The patent applies dynamics by enabling the rotatable body to rotate freely around the carabiner, which absorbs and redistributes forces generated during use. This dynamic rotation capability reduces force transfer to the user's hand while maintaining secure connection, resolving the contradiction between connection security and force reduction.
