Solution Overview

Problem

Existing aerial vehicles face challenges in efficiently supplying driving power to work devices installed on them without interference with flight and ground work, particularly when relying on external power sources.

Innovation Solution

The aerial vehicle is integrated with a power source, rotor, and power transmission unit to transmit power to the work device, eliminating the need for external power supply, and allowing for efficient power transmission through mechanical, electrical, or wireless means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If driving power is supplied from outside the aerial vehicle, then the work device can be operated, but the supply means such as cable may interfere with flight and ground work

Engineering Contradiction:
Improvework device operationVSAvoidinterference with flight and ground work
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the power supply function from external sources and relocates it inside the aerial vehicle. The power source is integrated into the aerial vehicle's structure, and the power transmission unit transmits power internally to the work device, eliminating the need for external cables and their associated interference problems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the power source with the aerial vehicle's existing structure. The power source is combined with the rotor system, where the rotor serves dual purposes: generating lift for flight and transmitting power to the work device. This integration eliminates separate power supply components and their interference.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a separate power supply source is provided for the work device, then driving power can be supplied, but the configuration of the aerial vehicle becomes complex

Engineering Contradiction:
Improvedriving power supplyVSAvoidaerial vehicle configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The rotor is designed to serve multiple functions: it generates lift for aerial vehicle flight and simultaneously transmits power to the work device. This multi-functionality eliminates the need for separate power supply components, simplifying the overall configuration while ensuring reliable power supply to the work device.

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

Solution Approach 2:

The power transmission unit is integrated with the rotor system rather than being a separate component. The rotor's rotational motion is directly utilized to drive the work device, merging the propulsion function with the power transmission function and reducing structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If external power supply is used, then the work device can be driven, but uninterrupted power supply cannot be ensured

Engineering Contradiction:
Improvework device drivingVSAvoidpower supply continuity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The power source is merged with the aerial vehicle's flight propulsion system. Since the rotor must be operating continuously for flight, it simultaneously provides continuous power to the work device, ensuring uninterrupted operation without dependence on external power sources that may be disconnected or interrupted.

Inventive Principle:
Principle #5Merging (Combining)
