Solution Overview

Problem

Existing rope wedge structures have a short sliding stroke due to closed ends, limiting their adaptability to various rope sizes and compromising strength and stability.

Innovation Solution

A rope fastener with a sliding channel featuring a first opening, allowing for increased sliding stroke and accommodating different rope sizes, combined with a spring-loaded fastening member that applies force to side walls to secure the rope.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the sliding channel ends are closed to form a complete sliding stroke, then the structural strength and stability are improved, but the sliding stroke becomes short and adaptability to various rope sizes is reduced

Engineering Contradiction:
Improveadaptability to various rope sizesVSAvoidstructural strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The sliding channel is divided into two parts: a closed sliding stroke portion that provides structural strength, and an open extension portion that increases sliding distance. The fastening member can slide along the entire length including both the closed channel and the open extension, allowing adaptation to different rope sizes while maintaining structural integrity of the main body.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the sliding channel ends are closed to form a complete sliding stroke, then the structural stability is improved, but the sliding stroke becomes short

Engineering Contradiction:
Improvesliding stroke lengthVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The sliding channel is segmented into a closed portion for stability and an open extension for increased stroke. The fastening member travels through both sections, gaining extended sliding capability while the closed main channel maintains structural stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sliding channel extends beyond the closed ends in a linear dimension, adding length to the sliding stroke without compromising the stability of the main structural body. The open extension provides additional sliding space in the same directional dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the sliding channel ends are closed, then the rope fastener maintains compact structure, but only specially designed small ropes can be used

Engineering Contradiction:
Improvecompatibility with different rope typesVSAvoidstructure design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The structure is segmented into a simple closed sliding channel and an open extension. This segmentation allows the fastening member to accommodate different rope types and sizes by sliding along the extended path, increasing versatility without significantly complicating the overall structure.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The rope fastener provides a larger space to accommodate various rope sizes, enhances tensile resistance through a bag mouth-type base body, and improves stability while maintaining effective rope fastening.

Implementation Method 1

a spring, which is arranged in the sliding channel, is located between the support portion and the fastening member, and is supported on the support portion to cause, by the elastic force thereof, the fastening member to apply force to the two side walls

AI summary

A rope fastener, comprising a base body (100) and a fastening member (200). A sliding channel (160) is formed on the base body (100), and the sliding channel (160) is provided with a first opening (161); two side walls (120) located on two sides of the sliding channel (160) on the base body (100) gradually become closer to each other towards the first opening (161); a support portion (140) is formed in the sliding channel (160) of the base body (100); and the fastening member (200) is slidably arranged in the sliding channel (160). The rope fastener further comprises a spring (300), which is arranged in the sliding channel (160), is located between the support portion (140) and the fastening member (200), and is supported on the support portion (140) to cause, by the elastic force thereof, the fastening member (200) to apply force to the two side walls (120), so as to fasten a rope (400) located between the fastening member (200) and the side walls (120). By means of the first opening (161), the two ends of the stroke of the sliding channel (160) are not completely closed, such that the sliding stroke of the fastening member (200) in the base body (100) is increased, thereby yielding a relatively large space to adapt to various ropes (400), and further simplifying the assembly of the rope fastener.
