Solution Overview

Problem

Prior art cable ties fail to effectively clamp hoses of varying diameters, leading to leaks and faulty connections due to the inability to conform to the hose's outer contour, especially near the head of the tie.

Innovation Solution

A cable tie design featuring a separate head and strap with a lug, where the head is configured to move relative to the lug, allowing for deformation and improved contact pressure to conform to the object's shape, reducing the likelihood of leaks and faulty connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the cable tie is formed as an integral one-piece structure, then the manufacturing is simple and robust, but the head cannot move relative to the strap to conform to varying hose diameters

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidadaptability to varying hose diameters
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The cable tie is divided into two separate components: a head and a strap with lug, allowing independent movement and deformation of each part while maintaining functional integration during use

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The head is designed to be moveable relative to the lug during tightening, enabling dynamic adaptation to different hose diameters and contours through controlled deformation

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the head is fixed relative to the strap, then the structure is stable and simple, but contact pressure cannot be introduced to deform the strap for better conforming

Engineering Contradiction:
Improvestructural stabilityVSAvoidconforming precision to hose contour
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The head-lug connection allows relative movement during tightening, enabling the strap to deform and conform precisely to the hose contour while maintaining structural integrity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The physical state of the strap changes from rigid to deformed through controlled movement of the head relative to the lug, allowing adaptation to different contours

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If the cable tie uses a one-piece design, then there are fewer parts to assemble, but it creates regions with no contact between the cable tie and hose near the head

Engineering Contradiction:
Improvenumber of partsVSAvoidconnection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

Separating the head and strap allows the strap to deform and eliminate gaps near the head, ensuring continuous contact with the hose for reliable sealing

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable tie is designed as a disposable component where the head and strap can be separately manufactured and assembled, accepting limited reuse

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

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 cable tie effectively conforms to the object's shape, reducing leaks and faulty connections by introducing controlled movement and deformation, enhancing its adaptability to various hose diameters.

Implementation Method 1

a contact pressure can be introduced via the moveable head onto the lug that brings about a deformation of the lug in the direction of the object to which the cable tie is attached

Methodology Applied
Scientific EffectDeformation: Deformation
