Carabiner Divider Layout for Multi-Anchor Fall Arrest Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall arrest systems face challenges in securely connecting users to multiple anchor points while maintaining ease of operation and preventing accidental detachment or injury during activities at heights.
Innovation Solution
A carabiner divider with a frame and openable gate, featuring a central body portion and multiple connection portions that divide the carabiner into distinct areas for secure attachment and detachment of harness components and fall arrest devices, including a collar for swiveling and C-shaped clip members for frictional engagement, preventing accidental gate opening or sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carabiner divider is used to connect to multiple anchor points, then the reliability of the fall arrest system is improved, but the device complexity increases
Solution Approach 1:
The carabiner divider is divided into multiple independent connection portions (first, second, third connection portions) that can be separately attached to different anchor points. Each connection portion functions as an independent attachment point, allowing the system to connect to multiple anchors while maintaining modular simplicity.
Solution Approach 2:
The carabiner divider serves multiple functions simultaneously: it divides the carabiner into distinct connection areas, provides multiple attachment points for different anchor points, and maintains structural integrity. This multi-functional design improves reliability without proportionally increasing complexity.
2Ease of operation
If the gate is made openable for attachment and detachment, then the ease of operation is improved, but the risk of accidental detachment increases
Solution Approach 1:
The stop formation is positioned to prevent the gate from opening accidentally by providing a physical barrier that must be deliberately overcome. This preliminary protective measure counteracts the potential harmful action of accidental gate opening while preserving the ability to intentionally open the gate when needed.
Solution Approach 2:
The gate is designed with a specific opening mechanism (twisting motion) that must be performed before the gate can actually open. This preliminary action ensures that the operator intentionally initiates the opening process, reducing the risk of accidental detachment while maintaining ease of operation.
3Adaptability or versatility
If the carabiner is divided into multiple areas for multiple connections, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The carabiner body is segmented into multiple distinct connection areas (first, second, and third connection portions) that can be independently utilized. This segmentation allows the same device to adapt to different connection configurations without requiring multiple separate devices, thereby improving versatility while managing complexity through modular design.
