Solution Overview

Problem

Existing aircraft designs require complex systems with numerous moving parts to achieve both vertical and forward motion, increasing manufacturing costs and operational complexity.

Innovation Solution

The aircraft incorporates fixed-position lift propellers for vertical motion and a separate forward-motion propeller, controlled independently by a local controller, reducing the need for angularly rotating parts and simplifying the wing structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex systems with numerous moving parts are used to achieve both vertical and forward motion, then the aircraft can perform multiple functions, but the manufacturing costs and operational complexity increase

Engineering Contradiction:

Improvemulti-functionalityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The aircraft system is segmented into independent functional modules: vertical lift propellers mounted on wings for vertical motion, and a separate pusher propeller at the rear for forward motion. This segmentation allows each component to be optimized independently and simplifies the overall system architecture by eliminating the need for complex rotating mechanisms that would otherwise be required to achieve both motion types with a single system.

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By dividing the propulsion system into separate vertical lift propellers and a forward motion pusher propeller, each component can be manufactured independently using simpler, more cost-effective processes. The fixed-position propellers eliminate the need for complex rotating mechanisms and angularly rotating parts, reducing manufacturing complexity and costs while maintaining multi-functionality.

3Adaptability or versatility

If angularly rotating parts are used to achieve both vertical and forward motion, then the aircraft can perform multiple functions, but the wing structure becomes more complex

Engineering Contradiction:

Improvemulti-functionalityVSAvoidwing structure complexity

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The wing structure is simplified by mounting fixed-position vertical lift propellers directly on the wings rather than using angularly rotating mechanisms. This segmentation of functions allows the wings to maintain their primary aerodynamic shape without complex rotating joints, while the vertical lift propellers provide the necessary vertical motion capability independently of the wing structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of rotating the entire wing or propeller assembly angularly to achieve both vertical and forward motion, the invention inverts the approach by using fixed-position propellers that rotate only in their designated direction (vertical lift propellers rotate vertically, pusher propeller rotates horizontally), eliminating the need for complex angular rotation mechanisms in the wing structure.

AI summary

One variation of an aircraft includes: a fuselage; a set of wings; a set of lift motors integrated into the set of wings; a set of batteries housed within the fuselage and electrically coupled to the set of lift motors; a set of lift propellers mechanically coupled to the set of lift motors; a forward-motion propeller; an engine mechanically coupled to the forward-motion propeller; and a controller. The controller is configured to: supply power to the set of lift motors to actuate the set of lift propellers to drive vertical motion of the aircraft in a take-off state; trigger actuation of the forward-motion propeller via the engine to drive forward motion of the aircraft in a forward-flight state.
