Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cloud printing technologies face inefficiencies and misuse, such as wasteful and unauthorized printing, due to lack of physical presence verification, leading to decreased adoption and enjoyment of cloud printing services.

Innovation Solution

Implementing a print server system that requires a presence code for users to verify their physical presence at the printer before releasing print jobs for printing, using a combination of mobile devices and cloud-aware printers to ensure legitimate and efficient use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cloud printing allows users to print from any device using any authorized printer, then printing accessibility and versatility are improved, but unauthorized and wasteful printing increases

Engineering Contradiction:

Improveprinting accessibilityVSAvoidunauthorized printing

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a presence verification system as an intermediary between the print job submission and actual printing. The system requires users to provide a presence code (generated via mobile device or printer display) and physically interact with the printer before printing occurs. This intermediary verification layer maintains printing accessibility while preventing unauthorized use.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If physical presence verification is implemented through presence codes, then unauthorized printing is reduced, but user convenience and ease of operation deteriorates

Engineering Contradiction:

Improvewasteful printingVSAvoiduser convenience

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The system enables self-service verification where users independently generate and provide presence codes through their mobile devices without requiring manual intervention from printer operators or administrators. The automated verification process maintains user convenience while effectively preventing wasteful printing.

Inventive Principle:

Principle #25Self-service

3Loss of energy

If presence code verification is required before printing, then printing security and resource efficiency are improved, but printing speed and productivity deteriorates

Engineering Contradiction:

Improveresource wasteVSAvoidprinting speed

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The presence code is generated and validated before the actual printing process begins. By performing the verification action preliminarily, the system ensures that only authorized users initiate printing, preventing resource waste while allowing rapid processing of legitimate print jobs without repeated verification delays.

Inventive Principle:

Principle #10Preliminary action

AI summary

A print server may include an application manager configured to receive a print job from a user and associate the print job with a printer. The print server may include a presence manager configured to provide a presence code for the print job and the printer, and to receive the presence code from the user in conjunction with a physical presence of the user at the printer, and a print job router configured to release the print job for printing by the printer, based on the receipt of the presence code.
