Solution Overview

Problem

The existing flying apparatuses lack a satisfactory support structure for heavyweight engines, which are prone to instability and potential damage.

Innovation Solution

The flying apparatus incorporates a framed main body assembled from multiple pipes, with adjustable engine mounts supporting the engine and oil pan, and a configuration that includes parallel output shafts for rotors to enhance stability and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the engine is mounted on a conventional single-piece frame, then the structure is simple, but the engine support stability is insufficient for heavyweight engines

Engineering Contradiction:
Improveengine support stabilityVSAvoidframe structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The frame is divided into multiple separate pipes (first pipe, second pipe, third pipe, fourth pipe) instead of using a single-piece structure. Each pipe is positioned at specific locations to support different parts of the engine, distributing the load and improving stability while maintaining manageable complexity through modular construction.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the engine mount position is fixed, then the manufacturing is simple, but the adaptability to different engine positions is poor

Engineering Contradiction:
Improveengine mount position adjustabilityVSAvoidmount structure complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The engine mount is designed with adjustable positioning capabilities along the pipes. The mount can be positioned at different locations and secured using fastening mechanisms, allowing adaptation to various engine positions and configurations while maintaining a relatively simple base structure of pipes and mounting brackets.

Inventive Principle:
Principle #15Dynamics

3Strength

If the engine weight is concentrated at one point, then the mounting is simple, but the structural load distribution is poor

Engineering Contradiction:
Improveframe load distributionVSAvoidmount configuration complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The engine support function is segmented across multiple pipes positioned at different locations (first pipe at front, second pipe at rear, third pipe at left side, fourth pipe at right side). This distributes the engine weight and structural loads across multiple support points, improving overall frame strength and load distribution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple pipes and engine mounts work together as an integrated support system. The pipes are connected to form a cohesive frame structure that collectively bears the engine load, combining individual simple elements into a stronger unified system capable of supporting heavyweight engines.

Inventive Principle:
Principle #5Merging (Combining)
