Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic locking carabiners are cumbersome to operate and prone to unintended unlocking due to complex multi-step mechanisms and vulnerability to forces, failing to provide reliable and efficient operation.
Innovation Solution
An automatic locking carabiner system featuring a set of rotatable latching sleeves that independently rotate between locked and unlocked states, allowing intuitive two-finger disengagement and reliable automatic relocking without requiring hand repositioning, utilizing a dual-rotation mechanism for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional screw type locking mechanism is used, then the gate can be locked in the closed configuration, but the mechanism becomes cumbersome to operate and may accidentally become unlocked
Solution Approach 1:
The locking mechanism is divided into two independent rotatable latching sleeves instead of a single complex screw mechanism. Each sleeve can rotate independently to engage or disengage from the gate frame coupling region, simplifying operation while maintaining reliable locking through dual independent latching points
Solution Approach 2:
Instead of requiring a multi-step screwing motion to lock, the invention uses rotation in the opposite direction to unlock. The latching sleeves are biased toward the locked state, so unlocking requires active rotation against the bias, preventing accidental unlocking while maintaining simple operation
2Reliability
If a multi-step locking mechanism is used, then the gate can be securely locked, but the operation requires high dexterity and becomes overly cumbersome
Solution Approach 1:
The locking function is segmented into two independent rotatable latching sleeves that operate separately. Each sleeve provides independent latching security, eliminating the need for complex multi-step operations while maintaining high locking security through redundant independent latching points
Solution Approach 2:
The two latching sleeves are combined in an internested rotational configuration where one sleeve rotates within the other. This merging of components into a compact nested structure reduces overall mechanism complexity while maintaining the security benefits of dual independent latching
3Reliability
If a conventional locking mechanism is used, then the gate can be locked, but it is vulnerable to obstruction and failure under certain forces
Solution Approach 1:
The latching sleeves are designed with rotational bias toward the locked state, creating preliminary counter-action against unintended unlocking forces. The biasing system pre-positions the sleeves in the locked configuration, requiring external force to overcome this bias and rotate the sleeves to the unlocked state
Solution Approach 2:
The internested rotational design of the two latching sleeves provides beforehand cushioning against obstruction forces. The nested configuration allows the sleeves to absorb and distribute mechanical stresses, preventing single-point failure under lateral obstruction forces or vibration

AI summary
An automatic carabiner gate locking system and method of operation. The system (100) includes a frame (120), a gate (140), a gate biasing system, and a gate locking system (160). The gate locking system (160) further includes a set of rotatable latching sleeves (162,164) disposed over the gate (140). When the gate (140) is in the closed state, the latching sleeves (162,164) independently rotate between an unlocked state in which the gate (140) is free to pivot and a locked state in which the gate (140) may be prevented from pivoting with respect to the frame (120). The locked state further includes rotationally orienting the latching sleeves (162,164) over the gate frame coupling region (124). The unlocked state further includes rotationally separating the latching sleeves (162,164) to expose a locking recess (170) over the gate recess (146), thereby allowing the gate (140) to pivot. A second embodiment of the present invention relates to a method of automatically locking a carabiner gate including automatically engaging a locking system and selectively disengaging the locking system.
