Solution Overview

Problem

Conventional small drones with rotary propeller systems are limited by the size and weight of their power sources, leading to reduced flying times and altitudes, as they require substantial and heavy batteries for operation.

Innovation Solution

Integration of graphene-based super capacitors or nanopore batteries within the propeller wings, which serve as both a structural component and a power source, providing a compact and lightweight power storage solution that enhances flight duration and altitude capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional batteries are used to power small drones, then the drone can operate, but the battery occupies substantial area and adds significant weight, reducing flight time and altitude

Engineering Contradiction:

Improveflight timeVSAvoidbattery weight

Core Design Contradiction:

Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The patent combines the power storage function with the propeller structure by integrating battery material layers directly into the propeller wings. This merging eliminates the need for separate battery compartments and reduces overall drone weight while maintaining sufficient power capacity for extended flight operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The propeller wings serve dual functions: providing aerodynamic lift/thrust and storing electrical energy. The battery material layers are embedded within the propeller structure, allowing the same component to perform both mechanical propulsion and power storage roles, thereby reducing total system weight.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Weight of moving object

If smaller and lighter batteries are used to reduce weight, then the drone becomes more maneuverable, but flying time and available altitudes are further reduced

Engineering Contradiction:

Improvedrone weightVSAvoidflying time

Core Design Contradiction:

Weight of moving objectVSDuration of action of moving object

Solution Approach 1:

The patent changes the energy density parameter by using advanced battery material layers with higher capacity per unit weight and volume. This allows the drone to maintain lightweight construction while achieving extended flight times, as the improved battery materials provide more energy in a smaller, lighter package.
