Dual-Ring Locking Carabiner to Prevent Accidental Gate Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current climbing and belay tools, such as carabiners and figure 8 instruments, often inadvertently open during use, leading to safety risks due to interactions between the tool, harness, and ropes, causing friction, jamming, and unintended unlocking, which can be dangerous.
Innovation Solution
A climbing tool with a figure 8-like design featuring two separate rings connected by an intermediate portion, a pivoted gate with locking mechanisms, and an integrated pulley system, along with reinforced structural elements to maintain integrity when carrying heavy loads, allowing for safer engagement of ropes and harnesses with reduced risk of accidental opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional carabiner with a single ring and gate is used, then the device is simple and easy to operate, but it inadvertently opens during use due to interactions with harness and ropes causing friction and jamming
Solution Approach 1:
The single ring structure is divided into two separate rings (first ring and second ring) connected by an intermediate portion. The gate is associated with the second ring while the first ring remains separate. This segmentation isolates the gate mechanism from direct contact with ropes and harness, eliminating friction and jamming that cause inadvertent opening, while maintaining overall structural simplicity.
2Adaptability or versatility
If a pulley system is integrated into the climbing tool, then the utility and versatility are improved, but the structural integrity may be compromised under heavy loads
Solution Approach 1:
The device separates climbing functions into two distinct rings: the first ring optimized for strength and load-bearing, and the second ring with the gate and pulley system optimized for versatility and rope management. This segmentation allows each ring to be specialized for its specific function without compromising the overall structural integrity.
Solution Approach 2:
The intermediate portion connecting the two rings acts as a mediator that transfers and distributes loads between the first ring (stronger structure) and the second ring (with pulley system). This allows the pulley system to be integrated while maintaining structural integrity through proper load distribution.
3Reliability
If the gate and locking mechanism are made straight for triple-lock mechanism, then the locking reliability is improved, but the ease of operation is reduced due to additional manipulation steps
Solution Approach 1:
The gate mechanism is segregated from the main load-bearing ring structure. The straight gate and locking mechanism are positioned on the second ring, separated from the first ring that handles primary loads. This segmentation reduces interference between locking operations and load forces, making the triple-lock mechanism more reliable while requiring minimal manipulation steps.

Function Achieved in This Case
The tool enables safer and more convenient performance of climbing-related functions by minimizing unwanted interactions between equipment components, preventing accidental opening and maintaining structural integrity under heavy loads.
Implementation Method 1
an elongated cylinder that transverses at least a portion of the second ring in such a way that the elongated cylinder faces toward the center of the second aperture

AI summary
A climbing instrument that comprises a first ring, a second ring that is larger than and engaged with the first ring. The second ring may comprise a gate that traverses a portion of the second ring and a rotatable cylinder that is positioned opposite the first ring and integrated within the second ring. The climbing instrument may also comprise a plurality of curved protrusions connected to and extending out and away from at least one of the first ring and the second ring.
