Integrated Tensioning Cable Tie for One-Sided Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable ties require looping around both the object and component for secure attachment, which can be difficult in confined spaces and leads to inconsistent clamping force due to individual worker variations.
Innovation Solution
A cable tie with a tensioning device integrated into the band, allowing insertion from one side and featuring pivotable locking heads and elastic sections to ensure consistent clamping force without looping, using film hinges for defined movement and locking projections for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional cable tie is used that requires looping around both the object and component, then the cable tie can provide secure attachment, but the installation becomes difficult or impossible in confined spaces
Solution Approach 1:
The cable tie is divided into two separate regions (first band region and second band region) that can be independently inserted into cable locks from one side, eliminating the need to form a complete loop around the component and object. This segmentation allows installation in confined spaces where traditional looping is impossible.
2Manufacturing precision
If manual insertion force is used to tension the cable tie, then the cable tie can be installed without tools, but the clamping force becomes inconsistent due to individual worker differences
Solution Approach 1:
The cable tie incorporates an elastic section that can be stretched to a defined extent during insertion. This elastic deformation serves as a physical parameter change that automatically ensures consistent tension and clamping force, regardless of individual worker strength or insertion technique.
3Ease of manufacture
If the cable tie is designed as a single integrated component, then production and handling are simplified, but the ability to achieve precise tension control is reduced
Solution Approach 1:
The cable tie is produced as a single injection-molded part but is functionally segmented into distinct regions: a first band region, an elastic section, and a second band region. This segmentation is built into the monolithic structure, maintaining production simplicity while enabling precise tension control through the elastic section's defined stretch characteristics.
4Productivity
If the cable tie requires looping around the component and object, then the attachment can be secure, but the installation time increases due to the additional maneuvering required
Solution Approach 1:
Instead of requiring the cable tie to be looped around the component and object from the outside, the invention inverts the approach by allowing both ends to be inserted into cable locks from one side. This reversal of the installation sequence eliminates the time-consuming maneuvering required for traditional looping while maintaining secure attachment.
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 secure attachment without looping, ensuring consistent clamping force and quality by compensating for insertion depth variations, suitable for difficult installation situations and reducing the need for tools.
Implementation Method 1
The first or second region of the band has an elastic section which is stretchable in a longitudinal direction of the band. The clamping force with which the object is held to the component is essentially defined by the elastic section, so that deviations in the insertion depth of the cable tie ends into the cable locks are compensated for by a greater or lesser stretching of the elastic section.
Implementation Method 2
The two resilient tabs ensure that the locking hook is elastically deformable and can therefore be inserted into a corresponding opening in the first band and locked there.

AI summary
A cable tie is proposed, consisting of a strap and an integrated tensioning device that divides the strap into a first and a second section, each featuring a toothed section. A cable duct or component to which an object, such as a cable harness, is to be attached can remain in its mounting position because both ends of the cable tie can be inserted into cable locks from one side. No tools are required for installation.
