Cable Tie Buckle Slot for Obstacle-Adjacent Belt Insertion

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cable ties face challenges in the structure or shape of the buckle, making it difficult to efficiently introduce the belt into the belt insertion hole, particularly when the bundle of tied articles is positioned adjacent to an obstacle.

Innovation Solution

The buckle features a slot that is gradually widened outward, allowing the belt to be laterally introduced into the belt insertion hole, and a vertical slot that allows lateral entry, combined with a design that enables the belt to be easily wrapped around the bundle and secured by an engagement claw.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the buckle has a conventional slot structure, then the belt can be laterally introduced into the belt insertion hole, but the belt introduction process is difficult and not smooth

Engineering Contradiction:

Improveease of belt introductionVSAvoidbuckle structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The slot structure is modified by changing its geometric parameters - specifically making the slot gradually wider from the belt insertion hole toward the inlet opening. This parameter change allows the belt to be easily introduced laterally into the belt insertion hole through the slot, resolving the contradiction between ease of operation and device complexity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of making the belt conform to a narrow slot, the slot is designed to widen outward, effectively inverting the traditional approach. This allows the belt to naturally guide itself into the correct position as it enters through the wider inlet opening and tapers toward the insertion hole

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If the belt is introduced through the inlet end of the belt insertion hole, then the belt can be fastened, but it is difficult to introduce the belt when the bundle is positioned adjacent to an obstacle

Engineering Contradiction:

Improveadaptability to positioning conditionsVSAvoidease of belt introduction

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention adds a lateral dimension for belt introduction through the slot, in addition to the conventional longitudinal introduction through the inlet end. This dimensional addition allows the belt to be introduced from the side when the bundle is positioned near obstacles, improving adaptability to different positioning conditions

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The slot acts as an intermediary structure that facilitates belt introduction from the lateral direction. It serves as a mediating pathway between the external environment and the belt insertion hole, enabling belt introduction when direct longitudinal access is blocked by obstacles

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A cable tie may include a desired length of belt, and a buckle connected to a proximal end portion of the belt. The buckle has a belt insertion hole and a slot continuous with the belt insertion hole. The belt insertion hole is configured such that the belt is longitudinally introduced thereinto. The slot is configured such that the belt is laterally introduced into the belt insertion hole therethrough. The slot includes an inlet opening that is gradually widened outward.
