Cable Tie With Cut Guide Grooves for Tool-Free Free End Removal

Solution Overview

Problem

Conventional cable ties require a separate cutting tool to remove the free end, posing safety risks and increasing the number of ties needed for larger diameters, leading to reduced binding effectiveness and increased accident risks.

Innovation Solution

A cable tie design featuring cut guide grooves on the tie band that allow the free end to be cut using a rotating force, eliminating the need for a cutting tool, and an auxiliary latching member to separate cables into bundles, enhancing binding force and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cutting tool is used to remove the free end of the tie band, then the free end can be removed cleanly, but the user may be injured or clothes may be damaged

Engineering Contradiction:

Improvefree end removalVSAvoiduser injury risk

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The tie band structure enables self-cutting through the interaction between the cut guide groove and the rotating force generated when the free end is twisted. The system uses its own components (the free end itself generates the cutting force) rather than requiring an external cutting tool, thereby eliminating the safety risks associated with knife usage while achieving clean free end removal.

Inventive Principle:

Principle #25Self-service

2Strength

If two or more cable ties are used to bind large diameter cables, then binding force is sufficient, but working steps and the number of necessary cable ties are significantly increased

Engineering Contradiction:

Improvebinding forceVSAvoidnumber of cable ties

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The tie band is divided into multiple independent binding portions along its length, each capable of providing binding force. This segmentation allows a single tie band to effectively bind large diameter cables by distributing the binding force across multiple sections, eliminating the need to use multiple separate cable ties and thereby reducing device complexity while maintaining sufficient binding strength.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the free end of the tie band is left intact, then no cutting tool is needed, but it disfigures the appearance of the cable organization

Engineering Contradiction:

Improveoperation simplicityVSAvoidappearance

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The tie band structure enables self-cutting through the interaction between the cut guide groove and the rotating force generated when the free end is twisted. The system uses its own components (the free end itself generates the cutting force) rather than requiring an external cutting tool, thereby eliminating the safety risks associated with knife usage while achieving clean free end removal.

Inventive Principle:

Principle #25Self-service

4Device complexity

If only one cable tie is used for binding, then device complexity is low, but binding effectiveness is reduced when cable diameter is large

Engineering Contradiction:

Improvenumber of cable tiesVSAvoidbinding effectiveness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The tie band is divided into multiple independent binding portions along its length, each capable of providing binding force. This segmentation allows a single tie band to effectively bind large diameter cables by distributing the binding force across multiple sections, eliminating the need to use multiple separate cable ties and thereby reducing device complexity while maintaining sufficient binding strength.

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

Enables easy cutting of the free end without tools, reduces the risk of injury or damage, and improves binding effectiveness by allowing cables to be sorted and held securely in two bundles, minimizing the risk of short circuits.

AI summary

Disclosed is a cable tie including a tie band which is formed in a shape of a strap to bind cables, and is provided with a plurality of serrated grooves continuously formed on a one surface thereof in a longitudinal direction, and a tie holder which is connected to one end of the tie band and includes a tie band passage, through which the other end of the tie band passes, and a serrated locking protrusion formed on an inner surface of the tie band passage and interference-latched to the serrated grooves. The tie band is provided with a cut guide groove formed on one or both widthwise edges thereof, so that a free end of the tie band remaining when the tie band binds the cables together is cut off by a rotating force generated when the free end is twisted, without using a cutting tool.
