Solution Overview

Problem

Current payload engagement systems for vehicles, such as UAVs, require human intervention for coupling and uncoupling payloads, leading to downtime and inefficiencies, especially when interacting with untrained users, as they often necessitate the UAV to land and power off between delivery runs.

Innovation Solution

A payload engagement system that includes a vehicle-supported portion and a payload-mounted portion with an insert component and a receptor component, allowing for secure coupling and uncoupling of payloads while the vehicle remains in flight through rotational and translational transitions between disengaged and engaged configurations, utilizing multiple insert arms and receptor units for stability and securement mechanisms to maintain engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If human interaction is required to couple and uncouple payloads, then safety of human users is ensured, but downtime between delivery runs increases and delivery efficiency decreases

Engineering Contradiction:
Improvesafety of human usersVSAvoiddelivery efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The payload engagement system performs coupling and uncoupling operations autonomously without human intervention. The insert component automatically engages with the receptor component through rotational and translational transitions, enabling the system to service itself and eliminating the need for human operators during payload changes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical coupling operations with an automated mechanical system. The engagement system uses controlled rotational and translational movements of the insert component relative to the receptor component to achieve secure coupling, substituting human-operated mechanical processes with automated actuation mechanisms.

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

2Reliability

If the UAV lands and powers off to couple or uncouple payloads, then secure engagement is achieved, but delivery turnaround time increases

Engineering Contradiction:
Improvesecure engagementVSAvoiddelivery turnaround time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The engagement system employs dynamic rotational and translational transitions of the insert component relative to the receptor component. These controlled movements enable secure payload engagement while the UAV remains in flight, eliminating the need for landing and power-off procedures between deliveries.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system maintains continuous operational capability by enabling payload coupling and uncoupling during flight operations. The UAV can perform multiple delivery runs without interruption for landing, maintaining continuous useful action and maximizing delivery turnaround efficiency.

Inventive Principle:
Principle #20Continuity of useful action

3Stability of the object's composition

If multiple insert arms and receptor units are used for stable engagement, then payload security is improved, but device complexity increases

Engineering Contradiction:
Improvepayload securityVSAvoidengagement system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The engagement system is divided into distinct modular components: multiple insert arms on the vehicle-supported portion and corresponding receptor units on the payload-mounted portion. Each insert arm can independently engage with its corresponding receptor unit, providing segmented but coordinated payload securement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert arms and receptor units are designed as universal components that can engage multiple payloads of different types and weights. The same basic engagement mechanism serves multiple functions: securing payloads during flight, enabling rapid payload changes, and maintaining system stability across various operational conditions.

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