Solution Overview

Problem

Remote workers face challenges in printing documents securely, as they often lack access to reliable print devices and must connect to potentially unsecure networks to send print jobs, risking exposure of confidential information.

Innovation Solution

A secure document printing and delivery management system that uses a processor and memory to receive print jobs, select appropriate print delivery vehicles, navigate them to designated locations, and verify security tokens before printing, ensuring secure and efficient document delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote workers connect to third party networks or email documents to external parties to access print services, then print accessibility is improved, but security is worsened due to exposure of confidential information

Engineering Contradiction:
Improveprint accessibilityVSAvoidsecurity risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a secure print delivery system as an intermediary between the remote worker and the print device. The system includes a server that receives print jobs, selects appropriate delivery vehicles from a fleet, and manages the secure transport of printed documents to recipients. This intermediary layer eliminates the need for remote workers to connect to unsecure third-party networks while maintaining print accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If print devices are made mobile and delivered via vehicles, then print service availability is improved, but system complexity is worsened

Engineering Contradiction:
Improveprint service availabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal print delivery system where a fleet of vehicles serves multiple functions: transporting print devices to various locations, delivering printed documents to recipients, and potentially providing other support services. The server manages this diverse fleet uniformly, selecting vehicles based on job requirements without needing separate specialized systems for each function.

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

Solution Approach 2:

The patent divides the print service into separate functional components: a central server that manages job routing and vehicle selection, a fleet of independent delivery vehicles, and portable print devices. This segmentation allows each component to be optimized independently while reducing overall system complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If security verification is performed at delivery location, then document security is improved, but delivery time is worsened due to additional verification steps

Engineering Contradiction:
Improvedata exposure riskVSAvoiddelivery time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent performs security verification in advance by requiring recipients to register and receive notifications before delivery. The system pre-validates recipient identities and prepares security credentials, so that when the delivery vehicle arrives, the verification process is streamlined and does not significantly delay delivery.

Inventive Principle:
Principle #10Preliminary action

AI summary

A secure document printing and delivery management system includes one or more print delivery vehicles, each of which includes an onboard print device. When the system receives a print job from a requesting device, it will select a print delivery vehicle instruct the print delivery vehicle to navigate to a delivery location. Upon arrival at the delivery location, the system will detect and verify a security token presented by a recipient. In response to detecting and verifying the token, the system may print the document (if not already printed) and it will present the document to the recipient.
