Unmanned Delivery Vehicle Authentication Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple unmanned ground vehicles (UGVs) deliver packages to an apartment building, recipients face difficulty in identifying the correct UGV for authentication, leading to a burdensome process of repeatedly performing authentication operations.
Innovation Solution
A package delivery method and system where a first UGV receives user authentication information and instructs a second UGV to unlock the storage containing the package, allowing the user to authenticate and retrieve the package from any UGV, reducing the need for multiple authentication attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple UGVs deliver packages to the same destination, then delivery capacity is improved, but recipient operation complexity increases
Solution Approach 1:
The patent introduces a communication system that acts as an intermediary between the recipient and multiple UGVs. The recipient inputs authentication information into one UGV, and this information is transmitted through the communication system to other UGVs, enabling coordinated unlocking without requiring the recipient to manually interact with each vehicle.
Solution Approach 2:
The authentication information received by one UGV is made universally applicable to all UGVs in the system. A single authentication input by the recipient can trigger unlocking sequences across multiple vehicles, making the authentication mechanism multi-functional rather than vehicle-specific.
2Productivity
If multiple UGVs wait for recipients at delivery destination, then delivery efficiency is improved, but authentication burden on recipient increases
Solution Approach 1:
The system performs preliminary coordination among multiple UGVs before the recipient arrives. Authentication information is prepared and transmitted in advance, and unlocking sequences are pre-coordinated so that when the recipient provides authentication input, the correct UGV is already positioned and ready to unlock, eliminating the need for repeated authentication attempts.
Solution Approach 2:
The communication system provides feedback mechanisms where UGVs transmit their status and location information to the recipient and to each other. This feedback loop enables the recipient to identify which UGV to input authentication into, and allows the system to coordinate unlocking responses efficiently without requiring multiple authentication attempts.
3Reliability
If recipient must find correct UGV for authentication, then security is improved, but operation complexity increases
Solution Approach 1:
The communication system serves as an intermediary that bridges security requirements and operational simplicity. It transmits authentication information between UGVs and coordinates unlocking actions, maintaining security through controlled information distribution while simplifying the recipient's task to a single authentication input regardless of which UGV is ultimately unlocked.

AI summary
In order to reduce a burden of receiving a package for a recipient, provided is a package delivery method including: receiving, by a first unmanned delivery vehicle, authentication information input by a user; and unlocking, by a second unmanned delivery vehicle, a key of a storage of the second unmanned delivery vehicle, which stores a package addressed to the user, based on the authentication information received by the first unmanned delivery vehicle.
