Solution Overview

Problem

Current drone delivery systems face challenges in securely loading and unloading payloads due to exposed payloads and difficulties in positioning drones for delivery to or retrieval from vertical structures, such as storage racks or multi-story buildings.

Innovation Solution

A delivery drone equipped with a dynamic support surface, such as a conveyor belt, and a docking station with coupling elements that align and secure the drone for efficient loading and unloading of packages, allowing for precise positioning and secure exchange of packages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If overhead grippers are used to secure payload, then the drone can carry packages, but the payload becomes exposed and insecure

Engineering Contradiction:
Improvepayload securityVSAvoidloading and unloading complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the payload handling function into separate components: the drone carries the payload in a contained area rather than using exposed grippers, and the docking station provides the secure containment structure. This segmentation allows the payload to be protected during transfer while keeping the drone design simpler.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The docking station acts as an intermediary between the drone and the final delivery location. The payload is transferred from the drone to the docking station's contained area, providing secure containment during the handoff process without requiring the drone itself to have complex secure containment mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If drones are positioned for open location delivery, then loading and unloading is simple, but delivery to vertical structures becomes difficult

Engineering Contradiction:
Improvedelivery location adaptabilityVSAvoidpositioning difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The docking station is designed as a universal interface that can be deployed on various structures including vertical surfaces. The coupling elements and contained area design allow the same docking station to work on different geometries, making the system adaptable to multiple delivery scenarios without requiring drone reconfiguration.

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

Solution Approach 2:

The system transitions from horizontal open-location delivery to vertical structure delivery by introducing docking stations that can be mounted on vertical surfaces. The coupling elements are designed to interface with the drone from different orientations, enabling operation in multiple spatial dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If coupling elements are used to mate drone with docking station, then package exchange is secure, but the system becomes more complex

Engineering Contradiction:
Improvepackage exchange reliabilityVSAvoiddocking system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The coupling system is segmented into separate male and female coupling elements that can be independently designed and manufactured. This segmentation simplifies the design of each individual component while providing secure mechanical interlocking when mated, reducing overall system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling elements combine multiple functions into a single mechanical interface: structural attachment, alignment guidance, and payload transfer coupling. This merging of functions reduces the number of separate components needed while maintaining secure and reliable package exchange.

Inventive Principle:
Principle #5Merging (Combining)
