Solution Overview

Problem

The final mile delivery of physical items to user-specified locations is inefficient, relying on human-operated vehicles which can be slow and labor-intensive, lacking the capability for autonomous and rapid delivery solutions.

Innovation Solution

An unmanned aerial vehicle (UAV) system that autonomously retrieves items from a source location, computes a route, and delivers them to a specified location, using communication with other UAVs and environmental data to navigate and avoid obstacles, and can land safely at attended or unattended locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If human-operated vehicles are used for final mile delivery, then delivery can be completed with simple technology, but delivery speed and efficiency are slow

Engineering Contradiction:
Improvedelivery speedVSAvoiddelivery system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent replaces human-operated mechanical vehicles with an unmanned aerial vehicle (UAV) system that uses autonomous navigation, GPS guidance, and automated control systems. This substitution of mechanical human-driven delivery with automated aerial delivery directly addresses the contradiction by dramatically increasing delivery speed while accepting the necessary complexity of autonomous systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The UAV is equipped with autonomous navigation capabilities, including GPS receivers, inertial measurement units, and onboard computing systems that enable it to independently compute routes, navigate to delivery locations, and complete deliveries without human intervention. This self-service capability resolves the contradiction by enabling rapid autonomous delivery while managing system complexity through automation.

Inventive Principle:
Principle #25Self-service

2Productivity

If human drivers are used for delivery, then operation is simple and familiar, but labor costs are high and productivity is low

Engineering Contradiction:
Improvedelivery productivityVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The UAV performs the complete delivery task autonomously, from receiving delivery parameters to navigating and completing the delivery. The system includes onboard computers that automatically compute routes, sensors that detect environmental conditions, and control systems that execute deliveries without human operation. This eliminates labor costs and increases productivity while the complexity is managed through integrated autonomous systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The UAV incorporates sensors, cameras, and communication systems that continuously monitor environmental conditions, track position, and provide feedback to the control system. This feedback loop enables the UAV to adapt to changing conditions, avoid obstacles, and complete deliveries accurately, resolving the contradiction by enabling high-productivity autonomous operation with intelligent control.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If UAVs navigate through complex environments, then delivery precision is improved, but safety risks from obstacles increase

Engineering Contradiction:
Improvedelivery precisionVSAvoidobstacle hazards
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The UAV employs onboard sensors, cameras, and detection systems that continuously scan the environment before and during flight to identify potential obstacles such as birds, other aircraft, or ground objects. The system takes preliminary protective actions by computing alternative routes or adjusting flight parameters to avoid detected hazards, thereby maintaining delivery precision while mitigating safety risks through advance obstacle detection and avoidance.

Inventive Principle:
Principle #9Preliminary anti-action
