Solution Overview

Problem

Existing jet engine designs require multiple interfaces and complex arrangements to maintain alignment with storage chambers and pipelines, making it difficult to position jet engines flexibly on an aircraft fuselage, especially for lateral connections.

Innovation Solution

A jet engine with a connection device that allows for easy attachment to various aircraft positions using a single attachment device, featuring fluid areas with interchangeable functionalities, and a design with symmetrically arranged engine attachment points and support struts for optimal line routing, enabling quick rotation and alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple interfaces are used to maintain engine orientation with bearing chambers and piping, then the engine can be mounted at different attachment points, but the device complexity increases

Engineering Contradiction:
Improvemounting position flexibilityVSAvoidnumber of interfaces
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single mounting interface that can accommodate multiple mounting positions (left side, right side, rear) of the aircraft. Instead of creating separate interfaces for each position, the invention uses one universal interface structure that maintains engine orientation and connects to bearing chambers and piping regardless of where the engine is attached on the aircraft fuselage.

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

Solution Approach 2:

The mounting interface is segmented into multiple mounting points that can be selectively used depending on the desired engine position. The interface structure includes distinct attachment locations that allow the engine to be mounted at different positions while maintaining proper orientation through the segmented design of the connection elements.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the engine is designed for lateral mounting on different sides of the aircraft fuselage, then mounting flexibility is improved, but the difficulty of implementing identical bearing chamber and piping arrangements increases

Engineering Contradiction:
Improvelateral mounting flexibilityVSAvoidimplementation difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies asymmetry by designing the mounting interface with asymmetric characteristics that allow the same interface structure to accommodate symmetric mounting positions (left and right sides). The asymmetric design of the interface elements enables proper orientation and connection regardless of which side of the aircraft the engine is mounted on, simplifying manufacturing while maintaining lateral flexibility.

Inventive Principle:
Principle #4Asymmetry

3Ease of operation

If a single attachment device is used for different mounting positions, then ease of operation is improved, but the ability to maintain proper fluid circuit functionality decreases

Engineering Contradiction:
Improvemounting effortVSAvoidfluid circuit functionality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies dynamics by designing fluid circuit connections that can dynamically adapt to different mounting positions. The fluid circuits are arranged and configured to automatically maintain proper functionality whether the engine is mounted on the left side, right side, or rear of the aircraft, allowing the same static interface structure to support dynamic mounting configurations without compromising reliability.

Inventive Principle:
Principle #15Dynamics
