Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional ground-operated machinery or airborne machinery is used to clean the electric grid, then cleaning can be performed, but the process becomes laborious and expensive

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidcomplexity of cleaning system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cleaning device is mounted on the electric cable itself and uses the cable's magnetic field to generate power for its own operation. The device autonomously navigates along the cable using the cable's tension and gravity, and performs cleaning without requiring external power supply or complex support infrastructure, thereby achieving self-service operation that eliminates laborious and expensive traditional cleaning methods

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces traditional mechanical cleaning systems (ground-operated machinery, helicopter-mounted equipment) with an electromagnetic-based system. The power supply module extracts energy from the cable's magnetic field to drive the cleaning mechanism, substituting complex mechanical support systems with electromagnetic energy conversion and simple mechanical navigation components

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If distilled water is used for cleaning live grid from ground-operated machinery, then safety is improved, but cost and labor requirements increase

Engineering Contradiction:
Improvesafety of cleaning operationVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device operates autonomously on live cables without requiring human operators to approach high-voltage equipment. The self-powered navigation and cleaning system eliminates the need for safety-conscious manual operations, maintaining reliability while dramatically improving ease of operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning device acts as an intermediary between the power cable and the cleaning function. It interfaces with the cable's electromagnetic field for power and uses this intermediate energy source to perform cleaning without requiring direct human interaction with high-voltage components, thereby ensuring safety while simplifying operation

Inventive Principle:
Principle #24Intermediary (Mediator)
