Solution Overview

Problem

ADSS optical cables in power systems are vulnerable to damage from small animals like squirrels and mice, which affects their service life and the stability and safety of the power grid due to complex terrains and frequent animal bites.

Innovation Solution

An all-dielectric self-supporting ADSS optical cable line protective device featuring a positioning mechanism with a baffle plate and fastening system that prevents animals from climbing and biting by securely mounting to the cable via a positioning sleeve and using spines and notches for enhanced stability and prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protective device is added to prevent animal damage, then the service life and safety of the optical cable is improved, but the device complexity increases

Engineering Contradiction:
Improveservice life and safety of optical cableVSAvoidstructure complexity of protective device
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protective device is divided into multiple independent components: a positioning mechanism with upper and lower positioning blocks, a protective mechanism with upper and lower baffle pieces, and fastening components. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and installation process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The positioning mechanism and protective mechanism are nested together, with the baffle plate mounted on the positioning sleeve. The upper and lower positioning blocks are positioned within the overall structure, creating a compact integrated device that reduces space occupation while maintaining functional complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If spines are densely arranged on the baffle plate to prevent animal climbing, then the protective effect is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveanimal climbing preventionVSAvoidspine arrangement precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

Spines are densely arranged only on specific local areas of the baffle plate - specifically on the arcuate edges of the upper and lower baffle pieces - rather than uniformly across the entire surface. This localized application of spines provides effective animal deterrents at the critical climbing contact points while reducing overall manufacturing complexity and precision requirements.

Inventive Principle:
Principle #3Local quality

3Device complexity

If the positioning mechanism and protective mechanism are integrated, then the device complexity is reduced, but the adaptability to different cable positions decreases

Engineering Contradiction:
Improveoverall structure simplicityVSAvoidadjustability to different cable positions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The positioning blocks are designed with movable and adjustable features, allowing them to be positioned at different locations along the optical cable. The fastening mechanism enables dynamic adjustment of the device to accommodate various cable diameters and mounting positions, providing adaptability while maintaining an integrated simple structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The integrated positioning and protective mechanism is designed to perform multiple functions: positioning the device on the cable, securing it firmly, and providing animal protection. The same structural components serve both positioning and protective roles, reducing overall device complexity while maintaining versatility through proper design of the positioning blocks and fastening systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)
