Solution Overview

Problem

Existing techniques for assembling and maintaining aircraft engines are satisfactory but seek improvements for enhanced efficiency and versatility in supporting various engine configurations.

Innovation Solution

An aircraft engine stand with a rotatable mount and interchangeable adaptors that allow for secure mounting of different engine types, providing easy access and adaptability through multiple axes of rotation and a coupler system for precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed, single-purpose engine stand is used, then the structure is simple and stable, but it cannot accommodate multiple engine configurations

Engineering Contradiction:
Improvecompatibility with multiple engine configurationsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The engine stand is designed with a universal mount that can accommodate multiple engine configurations through interchangeable adaptors. The mount includes a plurality of apertures distributed around a central axis, allowing different adaptor arrangements to secure various engine types (e.g., turbofan, turboprop, turbojet) to the same stand structure, eliminating the need for multiple dedicated stands.

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

Solution Approach 2:

The system is divided into modular components: a fixed support structure, a rotatable mount, and interchangeable adaptors. Each adaptor is designed to mate with specific engine types and can be independently attached or removed from the mount, allowing flexible reconfiguration without modifying the main stand structure.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the engine is fixed in a single position, then the mounting is stable, but access for maintenance operations is limited

Engineering Contradiction:
Improveaccess for maintenance operationsVSAvoidmounting stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mount is designed to be rotatable relative to the support about a transverse axis, allowing the engine to be positioned at different orientations during maintenance operations. This dynamic positioning capability provides improved access to various engine components while the mount includes locking mechanisms to ensure stability when positioned.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple dedicated stands are used for different engine types, then each stand is optimized for its specific engine, but the overall system complexity and cost increase

Engineering Contradiction:
Improveengine type compatibilityVSAvoidnumber of stands required
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single engine stand with universal mount and interchangeable adaptors replaces multiple dedicated stands. The mount can accommodate turbofan engines with large diameters, turboprop engines with different mounting patterns, and turbojet engines with varying configurations by simply changing the adaptors, eliminating the need to maintain separate stands for each engine type.

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

Solution Approach 2:

Adaptors can be quickly removed and replaced depending on the engine type being serviced. This allows the same physical stand to be reused for different engine configurations, reducing the total number of stands needed in the facility and lowering overall system cost.

Inventive Principle:
Principle #34Discarding and recovering
