Solution Overview

Problem

Unmanned aerial vehicles (UAVs) face challenges in package delivery due to susceptibility to high winds, making delivery impossible or difficult in windy environments, and existing design enhancements to overcome weight and air resistance issues increase drone costs.

Innovation Solution

A method and apparatus that utilize a wind model to identify windy conditions and dispatch additional drones to assist in package delivery, allowing multiple drones to collaborate and share the load, reducing the burden on individual drones and improving delivery precision and cost-effectiveness by using smaller, more efficient drones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single UAV tows a package, then the delivery system is simple and cost-effective, but the UAV becomes susceptible to high winds and delivery may be impossible or difficult in windy environments

Engineering Contradiction:
Improvedelivery reliability in windy conditionsVSAvoiddelivery system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The delivery system is segmented into multiple independent UAVs that can operate individually or in coordination. Instead of relying on a single large-capability UAV, the system divides the delivery task among multiple smaller UAVs, each capable of independent flight but collectively able to overcome environmental challenges like high winds through coordinated operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple UAVs are merged into a collaborative delivery system where they work together to transport a single package. The UAVs can combine their lifting and propulsion capabilities to counteract wind forces, effectively merging their individual capabilities to achieve reliable delivery in conditions that would defeat a single UAV.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If design enhancements are made to overcome weight and air resistance issues, then the UAV can handle heavier loads and better resist wind, but the drone costs increase

Engineering Contradiction:
Improvewind resistance capabilityVSAvoiddrone manufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of manufacturing expensive, heavily-enhanced single UAVs, the system segments the payload capacity requirement across multiple smaller, less expensive UAVs. Each UAV uses standard, cost-effective components, but the collective system achieves the required wind resistance and payload capability through coordinated operation of multiple units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs multiple smaller, more economical UAVs rather than investing in expensive, heavily-modified single units. These smaller UAVs can be manufactured at lower cost using off-the-shelf components, and the system achieves reliability through redundancy and coordination rather than through expensive individual unit enhancements.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
