Solution Overview

Problem

Existing solutions for removing rubber abrasion from airport runways are expensive and not cost-effective for smaller airfields, and hiring specialized companies increases operational costs.

Innovation Solution

A device comprising a sweeper as a base vehicle with a trailer-mounted high-pressure water system and high-pressure cleaning arrangement, including a nozzle bar and suction mechanism, for mechanically detaching and removing rubber coating from the runway surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specialized cleaning vehicles are used to remove rubber abrasion from runway landing zones, then cleaning effectiveness is improved, but device complexity and cost increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cleaning system is divided into separate functional modules: a sweeper base vehicle, a trailer with high-pressure water arrangement, and a high-pressure cleaning arrangement. This segmentation allows each component to be optimized independently and facilitates easier maintenance and operation while maintaining overall cleaning effectiveness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses a multi-functional configuration where the sweeper base vehicle performs both conventional sweeping operations and serves as a platform for the high-pressure cleaning system. The trailer can be attached to or detached from the base vehicle, allowing the system to adapt between different cleaning modes and reducing the need for separate specialized vehicles

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

2Reliability

If specialized cleaning vehicles are used to remove rubber abrasion from runway landing zones, then cleaning effectiveness is improved, but manufacturing cost increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The system utilizes the airport operator's existing sweeper fleet as the base vehicle, eliminating the need to manufacture entirely new specialized cleaning vehicles. The high-pressure cleaning components are added to existing assets, significantly reducing manufacturing costs while maintaining cleaning effectiveness

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention merges the high-pressure water system and cleaning arrangement with the existing sweeper vehicle and trailer infrastructure. This combination allows the airport operator to leverage existing investments in sweepers and trailers, reducing the need for new manufacturing and lowering overall system cost

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If high-pressure water jet is used to remove rubber abrasion, then cleaning effectiveness is improved, but operational cost increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidoperational cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The high-pressure water arrangement continuously applies cleaning action to the runway surface as the vehicle moves forward, eliminating the need for repeated cleaning passes. The coordinated movement of the water jets and suction system ensures continuous removal of rubber particles, reducing overall operational time and energy consumption

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system extracts loosened rubber particles and excess water from the cleaning zone using the suction arrangement and exhaust duct. This immediate removal prevents re-deposition of particles and allows the high-pressure water system to operate more efficiently, reducing the energy required for repeated cleaning cycles

Inventive Principle:
Principle #2Taking out (Extraction)
