Solution Overview

Problem

Existing mobile aeroengine washing systems are inflexible and cumbersome, struggling to accommodate various engine sizes and heights, and are not compact enough for efficient transportation and operation.

Innovation Solution

A mobile washing system with a platform, drip tray, and lateral walls that can be automatically adjusted and deployed using actuation means, such as rotation and elongation, to accommodate different engine configurations, featuring a control system programmed for optimal positioning and a droplet separator for efficient effluent collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the height adjustment mechanism lifts the whole frame to accommodate different engine sizes, then the system can adapt to various engine heights, but the mechanism becomes necessarily heavy and complex

Engineering Contradiction:
Improveaccommodation of different engine sizesVSAvoidheight adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lateral walls are divided into fixed and movable segments. The movable segments can be independently adjusted to different positions using actuation means, allowing adaptation to different engine sizes without requiring the entire frame to be lifted or reconfigured.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lateral walls are designed with actuation means that enable them to move between fixed and movable states. This dynamic configuration allows the walls to adapt their position and orientation based on the specific engine being serviced, providing versatility without permanent structural changes.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If lateral walls and droplet separator are made fixed size for structural simplicity, then the device is easier to manufacture, but they cannot easily accommodate larger engine nozzles diameters

Engineering Contradiction:
Improvefixed size structureVSAvoidaccommodation of different engine nozzle diameters
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The lateral walls incorporate actuation means that allow them to transition between different positions and orientations. This enables the same fixed-structure walls to dynamically adapt to different engine nozzle diameters, maintaining ease of manufacture while achieving versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lateral walls are designed to perform multiple functions: they can be positioned to accommodate different engine sizes, orientations, and configurations. The actuation means enable the same structural elements to serve various purposes across different washing scenarios.

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

3Ease of operation

If the washing system is made compact for efficient transportation, then the system is easier to transport and store, but it may lack the flexibility to accommodate various engine configurations

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidaccommodation of different engine configurations
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The lateral walls are designed with actuation means that allow them to be repositioned and reconfigured. When not in use, the walls can be moved to compact positions for efficient transportation and storage. When needed, they can be deployed to accommodate various engine configurations, providing both compactness and versatility.

Inventive Principle:
Principle #15Dynamics

4Productivity

If automatic control system is implemented for wall positioning, then the operation efficiency is improved and precision is increased, but the device complexity and cost increase

Engineering Contradiction:
Improvewall positioning efficiencyVSAvoidcontrol system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system is designed to automatically determine the required wall positions based on engine parameters and autonomously actuate the walls to the correct configurations. This self-service capability eliminates the need for manual positioning, improving productivity while the automated decision-making reduces the complexity of human-machine interfaces.

Inventive Principle:
Principle #25Self-service
