Solution Overview

Problem

Conventional rope binding tools for flexible container bags face issues with easy untying during storage or movement, and inefficient release of closing ropes during discharge, leading to reduced working efficiency and potential content leakage or accidents.

Innovation Solution

A rope fixture with a plate-shaped body featuring through-holes and slits that securely lock the closing rope, ensuring it does not easily come loose, comprising a configuration with strategically placed through-holes and rope locking portions to maintain binding strength and facilitate easy release during discharge operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the closing rope is firmly tightened, then the binding strength is improved, but the time required to loosen the rope increases and working efficiency drops

Engineering Contradiction:

Improvebinding strengthVSAvoidtime to loosen rope

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The closing rope is divided into multiple segments that pass through separate through-holes in the plate-shaped body, with each segment independently locked by rope locking portions. This segmentation allows the rope to be securely held while enabling quick release by simply pulling one end, resolving the contradiction between strong binding and easy release.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rope fixture transitions from a static binding state to a dynamic release state through the interaction between the closing rope and the plate-shaped body. The rope can be quickly transitioned from a tightly bound state to a released state by pulling, making the binding strength adjustable and the release process efficient.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the closing rope is loosely tightened, then the ease of untying is improved, but contents may leak out due to the discharge opening widening

Engineering Contradiction:

Improveease of untyingVSAvoidprevention of content leakage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The closing rope is segmented and passed through multiple through-holes, with each segment independently secured by rope locking portions. This segmentation provides multiple friction points that collectively maintain strong binding, preventing the discharge opening from widening and ensuring content security while keeping the rope easy to untie.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The plate-shaped body acts as an intermediary between the closing rope and the bag opening. It provides a structured interface with through-holes and rope locking portions that distribute the binding force evenly, maintaining reliable closure without requiring excessive rope tension, thus preventing leakage while ensuring ease of untying.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If a conventional rope fixture is used, then the device complexity is reduced, but the reliability of binding during storage and movement deteriorates

Engineering Contradiction:

Improvestructure simplicityVSAvoidbinding reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The plate-shaped body serves multiple functions: it guides the closing rope through its through-holes, secures the rope segments via rope locking portions, and maintains binding reliability during storage and movement. This multi-functional design achieves reliable binding without increasing device complexity, as the single plate structure integrates all necessary features.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The rope fixture is designed to maintain its own binding reliability through the inherent friction between the closing rope and the plate-shaped body's through-holes and rope locking portions. The structure self-regulates the binding force without requiring additional components or complex mechanisms, ensuring reliable binding during storage and movement while keeping the device simple.

Inventive Principle:

Principle #25Self-service

4Device complexity

If manual work is used to loosen the closing rope, then the device complexity is minimized, but the productivity decreases due to substantial time consumption

Engineering Contradiction:

Improvemechanism simplicityVSAvoidworking efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The closing rope is segmented and passed through multiple through-holes in the plate-shaped body, with each segment independently locked. This segmentation enables quick release by simply pulling one end of the rope, which simultaneously loosens all segments. This simple mechanical design dramatically reduces the time required to loosen the rope compared to conventional manual untying methods, thereby improving productivity without increasing device complexity.

Inventive Principle:

Principle #1Segmentation
