Solution Overview

Problem

Conventional anchoring devices for overhead line cables, particularly those with optical fibers, are complex to use due to the association of drums with holding elements, making it difficult to place the cable correctly and requiring additional components that complicate the installation process.

Innovation Solution

An anchoring device featuring an immobilizing member with an annular groove and a connecting member, where the groove has a holding sector and a transition sector, allowing the cable to be securely fastened without a cleat, enabling easy installation and compact design, allowing multiple devices to be arranged side-by-side on a support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional anchoring devices use drums with holding elements, then the cable can be immobilized, but the device becomes complex to use and difficult to install

Engineering Contradiction:
Improvecable immobilizationVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent removes the drum and holding elements from the anchoring device, retaining only the essential groove structure in the immobilizing member. This extraction of unnecessary components simplifies the device while maintaining cable immobilization capability through the groove geometry alone

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The groove structure in the immobilizing member is designed to automatically secure the cable through its geometric configuration, eliminating the need for additional holding elements or complex mechanisms. The cable itself serves to tighten and secure within the groove structure

Inventive Principle:
Principle #25Self-service

2Reliability

If conventional anchoring devices use drums with associated holding elements, then the cable can be secured, but the device size increases and multiple devices cannot be arranged side-by-side

Engineering Contradiction:
Improvecable securityVSAvoiddevice compactness
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

By removing the drum and associated holding elements, the device volume is dramatically reduced. The groove structure requires minimal space while maintaining effective cable security, enabling compact arrangement of multiple devices on a single support

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The functions of the drum, holding elements, and cable securing mechanism are merged into a single integrated groove structure in the immobilizing member, eliminating the need for separate components and reducing overall device volume

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional anchoring devices use multiple components, then the cable can be immobilized, but the number of parts increases and installation becomes more difficult

Engineering Contradiction:
Improvecable immobilizationVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the drum and holding elements from the system, reducing the number of components to just the immobilizing member with an integrated groove structure and the connecting member, thereby simplifying the overall device complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The immobilizing member integrates the groove structure directly into its body, combining what were previously separate components (drum, holding elements, immobilizing member) into a single unified component, reducing assembly steps and complexity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

This device comprises a locking member (16) and a connecting member (17). The locking member (16) has an annular groove (30) for receiving the cable (11), oriented radially and opening onto the periphery of the locking member (16). This groove (30) includes a retaining sector (35) and a transition sector (34). Between a slack end (19) and a tensioned end (18), the cable successively has a first portion that passes through the transition sector (34) and joins the retaining sector (35), then a second portion making a complete turn around a hub (20) while against a bottom surface in the retaining sector (35), then in the retaining sector (35) a third portion (39) covering the second portion (38), and finally a fourth portion leaving the locking member (16).
