Solution Overview

Problem

Conventional carabiners are difficult to use and prone to allowing ropes or objects to undesirably slide between their ends, lacking effective mechanisms for simultaneous opening and closing of enclosures.

Innovation Solution

A carabiner design featuring a frame with a movably attached gate that bisects the internal space into two enclosures, allowing for simultaneous opening and closing with a single gate, which is biased towards a closed position to prevent object slippage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional carabiner uses a single gate to open and close the loop, then the device is simple in structure, but it is difficult to use and allows objects to undesirably slide between the ends

Engineering Contradiction:
Improveease of useVSAvoidprevention of object slippage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The internal space of the carabiner is divided into two separate enclosures by the gate when closed. This segmentation prevents objects from sliding from one end to the other, as the gate acts as a physical barrier dividing the space into distinct compartments that are both openable and closable with a single gate operation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the gate is biased towards a closed position, then object slippage is prevented, but the gate requires more force to open

Engineering Contradiction:
Improveprevention of object slippageVSAvoidforce required to open gate
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The spring-loaded gate mechanism provides automatic biasing towards the closed position, ensuring that the gate remains closed and prevents object slippage without requiring active user intervention. The spring force continuously pushes the gate toward closure, making the carabiner self-regulating and reliable while maintaining ease of operation through quick-release functionality.

Inventive Principle:
Principle #25Self-service

AI summary

Systems and methods for providing a carabiner are discussed herein. While the carabiner can have any suitable component, in some cases, it includes a frame that extends between a first end and a second end, with the frame being defining an internal space, and with the frame defining a gap between the first and second end. Additionally, the carabiner includes a gate that is movably connected to the frame such that the gate is movable between a closed position (in which the gate closes the gap) and an opened position (in which it the gap is open). In some cases, a portion of the gate is configured to divide the internal space into a first and a second enclosure when the gate is in the closed position. Additionally, in some cases, the gate defines an aperture that receives the second end when the gate is closed. Other implementations are described.
