Solution Overview

Problem

Current delivery models leave packages vulnerable to theft and incur additional costs and inconvenience due to the need for signatures and repeated delivery attempts when recipients are absent, lacking secure and efficient package delivery solutions.

Innovation Solution

An automated system that grants delivery personnel access to designated areas within premises while maintaining other access points secure, determines occupant identity, and provides delivery instructions based on preferences or demographics, enabling secure and efficient package delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If delivery personnel are granted access to the entire premises, then package delivery can be completed, but security risks increase and theft vulnerability increases

Engineering Contradiction:
Improvepackage deliveryVSAvoidtheft vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system divides the premises into multiple zones with different access levels. Delivery personnel are granted access only to the specific delivery zone rather than the entire premises. This is achieved through the access control system that identifies the recipient and provides zone-specific access credentials, thereby enabling package delivery while minimizing security risks.

Inventive Principle:
Principle #1Segmentation

2Reliability

If signature requirements are enforced for all deliveries, then security and accountability improve, but delivery time increases and convenience decreases

Engineering Contradiction:
Improvedelivery accountabilityVSAvoiddelivery time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system dynamically adjusts the delivery process parameters based on the recipient's identity and delivery history. For trusted recipients or pre-authorized deliveries, the signature requirement parameter is changed from mandatory to optional or eliminated entirely. This allows the system to maintain accountability for high-risk deliveries while significantly reducing delivery time and improving convenience for routine deliveries.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If repeated delivery attempts are made when recipients are absent, then delivery completion rate improves, but cost increases and inconvenience increases

Engineering Contradiction:
Improvedelivery completion rateVSAvoiddelivery cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system enables recipients to self-manage their deliveries through mobile devices or online portals. When a delivery is attempted and the recipient is absent, the system automatically notifies the recipient who can then select alternative delivery options such as designated drop-off locations, scheduled redelivery times, or authorization for leave-without-signature. This self-service approach eliminates the need for multiple manual delivery attempts, improving completion rates while reducing costs.

Inventive Principle:
Principle #25Self-service

4Object-affected harmful factors

If access control systems are implemented for delivery, then security improves, but system complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The access control system is designed to perform multiple functions beyond just granting physical access. It simultaneously identifies recipients, determines appropriate delivery zones, manages authorization levels, tracks delivery attempts, and integrates with notification systems. By consolidating these functions into a single universal system, the patent reduces overall complexity compared to having separate systems for each function while maintaining high security standards.

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

AI summary

Methods, systems, and apparatuses for occupancy identification for guiding delivery personnel are described. One method for a security or home automation system may include receiving an indication regarding a delivery of a package to a structure associated with the security or home automation system, determining an occupancy of the structure based on the received indication, identifying an identity of an occupant within the structure based on the determined occupancy, and transmitting delivery instructions, to a delivery person associated with the delivery of the package, regarding how to deliver the package based on the identity of the occupant or the determined occupancy.
