Double Carabiner Sliding Lock to Prevent Gate Dislodgment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carabineers often detach undesirably due to gate dislodgment during movement, leading to the opening of the gate and detachment from attachment points.
Innovation Solution
A locking mechanism featuring sliding locks that can move between locked and unlocked positions, positioned in notches on the carabineer body, prevents the gate from opening by pressing against a notch, ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional carabineer gate is used, then the device is simple and easy to operate, but the gate may dislodge during movement causing unwanted detachment
Solution Approach 1:
The sliding lock mechanism transitions between static locked and unlocked states dynamically. The lock slides along the gate structure, providing a secure locked position during movement and an accessible unlocked position when needed, resolving the contradiction between security and operability.
Solution Approach 2:
The sliding lock acts as an intermediary element between the gate and the carabineer body. It mediates the connection by providing an additional securing mechanism that prevents direct gate-dislodgment while maintaining the simplicity of the original gate structure.
2Reliability
If a sliding lock mechanism is added to prevent gate dislodgment, then gate security is improved, but the device complexity increases
Solution Approach 1:
The locking function is segmented from the main gate structure into a separate sliding lock component. This allows the gate to remain simple for opening/closing operations while the distinct sliding lock provides the security function, reducing operational complexity despite added security features.
Solution Approach 2:
The sliding lock mechanism is designed to be self-latching when in the locked position, requiring only a simple sliding motion to engage or disengage. The mechanism serves itself by maintaining security automatically once locked, minimizing the operational effort required from the user.
