Solution Overview

Problem

Existing security systems fail to effectively secure delivered packages when recipients are not home, leading to increased theft and financial loss.

Innovation Solution

An AI-powered entry management system with a device comprising a camera, microphone, and speaker, capable of processing visual and audio data to authenticate authorized individuals or images, controlling access points, and interacting with network devices like drones, robots, and smart home systems to enhance security and manage package delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If packages are left unsecured by the door for delivery, then delivery convenience is improved, but package security deteriorates leading to theft

Engineering Contradiction:
Improvedelivery convenienceVSAvoidpackage security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an intermediary access point (such as a locked compartment or secure drop-off location) between the delivery vehicle and the recipient's interior space. This intermediary structure allows packages to be delivered without direct access to the recipient while maintaining security, resolving the contradiction between delivery convenience and package security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If access control is tightened to prevent theft, then package security is improved, but delivery convenience deteriorates

Engineering Contradiction:
Improvepackage securityVSAvoiddelivery convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements self-service mechanisms where the access point automatically authenticates and releases packages without requiring manual intervention from security personnel or the recipient. The system autonomously verifies delivery credentials, unlocks the access point, and secures the package, maintaining both security and convenience.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical access control (physical keys, locks requiring human operation) with automated electronic or optical authentication systems. This substitution enables secure access without requiring physical presence or manual manipulation, resolving the contradiction between tightened access control and delivery convenience.

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

3Reliability

If AI authentication is implemented to verify authorized individuals, then access security is improved, but system complexity increases

Engineering Contradiction:
Improveaccess securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex manual authentication procedures with AI-driven automated verification systems using biometric recognition (facial, fingerprint, or voice recognition). This substitution enhances access security while reducing operational complexity by eliminating the need for manual credential verification, security personnel, or physical key management.

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

AI summary

An artificial intelligence (AI) entry management (EM) security system includes a camera, a microphone, a motion detector, a speaker, and a software platform. Geofences are utilized to create boundaries around physical areas, such as locations for package delivery or property boundaries. The EM device and other devices connected to the software platform are configured to monitor the geofences and detect a presence of an activity, an event, an object, or a device. At least one license plate reader is utilized to read license plate characters. Voice recognition and voice identification are used to grant or deny permissions for individuals on a property.
