Solution Overview

Problem

High voltage power transmission and distribution systems face insulator failure due to dirt or dust accumulation, which forms conductive paths and leads to premature mechanical failure, and existing cleaning methods struggle to efficiently access and clean the inter-disc regions of insulator stacks.

Innovation Solution

A handheld cleaning device with multiple prongs, using solvent and spongiform and rubber bladed attachments, designed to operate safely at high voltages, effectively cleans multiple insulator discs at once, including inter-disc regions, with extendable and retractable support prongs to cover all surfaces without physical clearance issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional cleaning methods are used for insulator discs, then the cleaning process is simple, but the cleaning efficiency is low and inter-disc regions cannot be completely cleaned

Engineering Contradiction:
Improvecleaning efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cleaning device is divided into multiple prongs (typically 3-5), each equipped with cleaning attachments, allowing simultaneous cleaning of multiple insulator discs and inter-disc regions. This segmentation enables the device to handle complex cleaning tasks efficiently while maintaining manageable structural complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support prongs are designed with telescoping capability, allowing them to extend and retract like nested dolls. This enables the prongs to be compact during transport and storage, yet extend to sufficient length during operation to reach and clean inter-disc regions effectively

Inventive Principle:
Principle #7Nested doll (Nesting)

2Area of stationary object

If cleaning attachments extend far to cover inter-disc void regions, then complete coverage is achieved, but physical clearance issues occur during cleaning movements

Engineering Contradiction:
Improvecleaning coverage areaVSAvoidease of operation
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The support prongs are designed as telescoping structures that can dynamically adjust their length. During cleaning operations, the prongs extend to provide sufficient coverage of inter-disc regions, then retract to avoid physical clearance issues when maneuvering around insulator stacks, enabling complete coverage without operational constraints

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If maintenance personnel work close to insulator discs for cleaning, then direct access is improved, but safety from high voltage and protection of fragile discs is reduced

Engineering Contradiction:
Improveaccess to insulator discsVSAvoidsafety and protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cleaning attachments utilize soft, deformable materials such as spongiform structures and rubber blades. These flexible elements provide effective cleaning contact with insulator surfaces while being gentle enough to prevent damage to fragile glass discs, and the device structure maintains electrical insulation to protect personnel from high voltage

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The cleaning device acts as an intermediary between the maintenance personnel and the insulator discs. It provides the necessary physical contact for cleaning while maintaining electrical insulation barriers, thereby protecting both the personnel from high voltage exposure and the fragile discs from direct human contact that could cause damage

Inventive Principle:
Principle #24Intermediary (Mediator)
