Solution Overview

Problem

Manual cleaning of road drains is inefficient, exposes operators to biological risks, and increases the likelihood of occupational diseases due to prolonged and physically demanding operations.

Innovation Solution

An automated apparatus mounted on a motor vehicle equipped with an automatic manhole cover removal unit, a scraper tool, suction element, and a remote viewing system, which simplifies and speeds up the cleaning process while minimizing human intervention and exposure to hazards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual cleaning operations are used, then the apparatus complexity is low, but the productivity is low and cleaning time is long

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

Solution Approach 1:

The patent replaces manual mechanical cleaning operations with an automated mechanical system mounted on a motor vehicle. The apparatus includes automatic scraping mechanisms, suction systems, and hydraulic lifting devices that perform cleaning functions without direct human intervention in the drain, thereby increasing productivity while managing complexity through integrated automation.

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

Solution Approach 2:

The cleaning apparatus is designed to perform cleaning operations autonomously once positioned at the drain. The system self-regulates through automated control of the scraping tools, suction equipment, and manhole cover handling, reducing the need for continuous manual operation and improving cleaning efficiency.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual cleaning operations are used, then the device complexity is low, but the biological risk and occupational disease risk are high

Engineering Contradiction:
Improveoperator safetyVSAvoidapparatus complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an automated apparatus as an intermediary between the operator and the contaminated drain environment. The motor vehicle-mounted system performs all functions requiring contact with waste material, including scraping, suction, and manhole cover handling, thereby protecting operators from biological hazards while managing complexity through integrated automation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Manual mechanical operations are replaced with automated mechanical systems that perform cleaning functions from a protected position. The apparatus includes automated scraping mechanisms, suction systems, and hydraulic lifting devices that eliminate direct human contact with contaminants, improving operator safety while managing complexity through integration.

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

3Loss of time

If manual cleaning operations are used, then the apparatus complexity is low, but the cleaning time per drain is long

Engineering Contradiction:
Improvecleaning timeVSAvoidapparatus complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent implements continuous cleaning operations through the motor vehicle-mounted apparatus that can move systematically from drain to drain without interruption. The integrated system performs multiple functions (manhole cover removal, scraping, suction, and cover replacement) in continuous sequence, eliminating the time losses associated with manual repositioning and tool changes, thereby reducing total cleaning time while managing complexity through automation.

Inventive Principle:
Principle #20Continuity of useful action

4Productivity

If automated cleaning apparatus is used, then the productivity is improved, but the device complexity increases

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

Solution Approach 1:

The motor vehicle-mounted apparatus is designed as a universal cleaning system that can handle multiple drain types and configurations. The integrated system performs manhole cover removal, scraping, suction, and cover replacement functions, allowing a single complex apparatus to replace multiple simpler manual tools and operations, thereby improving productivity while consolidating complexity into one multi-functional system.

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