Solution Overview

Problem

The widespread adoption of e-commerce has led to parcels being left unattended, making them vulnerable to theft, causing a burden on e-commerce businesses, delivery companies, and consumers.

Innovation Solution

A lockbox system with multiple compartments controlled by an access device using access codes, allowing secure package storage until the user arrives home, with features like compartment-specific codes, network connectivity, and integrated security measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If parcels are left unattended at homes or places of business for e-commerce delivery, then delivery convenience and efficiency are improved, but vulnerability to theft increases

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidtheft risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The lockbox is divided into multiple compartments, each capable of being independently locked and unlocked. This segmentation allows different access codes to control different compartments, enabling selective access control while maintaining overall security against theft.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lockbox acts as an intermediary secure storage solution between the deliverer and the user. It receives parcels from deliverers under controlled access conditions and holds them securely until the user retrieves them, eliminating the need for unattended parcel placement while maintaining delivery efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If access codes are made unique for each compartment to enhance security control, then access control precision is improved, but system complexity increases

Engineering Contradiction:
Improveaccess control securityVSAvoidaccess code management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The access device is designed to handle multiple access codes and control multiple compartments through a single unified interface. This multi-functionality allows the system to maintain high security with unique compartment codes while simplifying user interaction through a universal access device that manages all compartments.

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

3Object-affected harmful factors

If the lockbox is physically secured to structure to prevent movement, then security against theft is improved, but installation complexity increases

Engineering Contradiction:
Improvetheft preventionVSAvoidinstallation ease
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The lockbox incorporates multiple attachment mechanisms (such as wall mounting brackets, floor anchors, or both) that provide more security than a single method would offer. This partial or excessive action approach ensures secure installation while maintaining flexibility in installation locations and methods.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A lockbox and parcel management system is implemented in which a lockbox having multiple compartments is controllable via an access device that locks and unlocks respective compartments upon receiving a proper access code input. A user may place an order with an e-commerce service using an e-commerce application or website. The e-commerce service, upon receiving the order, may transmit order information to a lockbox remote service which can communicate with a user device associated with the user who placed the order, the access device for the lockbox, and a deliverer's device from the delivery company. The lockbox remote service or authorized user/owner may set access codes for the deliverer to open and place a parcel in a lockbox's compartment for safe and secure storage until the user arrives home.
