Solution Overview

Problem

Users need to pre-know and set optimal print settings to avoid wasting paper during printing, as existing technologies lack a mechanism to automatically determine and notify more efficient settings.

Innovation Solution

A print processing system that includes a printer driver and user interface, which determines whether paper can be saved by analyzing print settings and providing options to rotate images or remove margins, allowing users to set paper-saving functions through a user-friendly interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If the user manually sets print settings to save paper, then paper waste is reduced, but the user needs to pre-know optimal settings which increases operational complexity

Engineering Contradiction:
Improvepaper wasteVSAvoidsetting complexity
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The system automatically determines optimal print settings without user intervention. The determining unit analyzes the print job and autonomously selects settings that minimize paper waste, eliminating the need for users to manually optimize settings while achieving paper conservation goals.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The notification unit provides feedback to the user about the determined print settings and their paper-saving benefits. This feedback mechanism informs users about automatic optimizations made, allowing them to review and accept the suggested settings, thereby reducing paper waste without requiring expert knowledge.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the system automatically determines optimal print settings, then ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvesetting simplicityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The determining unit serves multiple functions: it analyzes print jobs, evaluates different print settings, calculates paper usage for each option, and determines the optimal settings. By consolidating these multiple functions into a single multi-functional component, the system achieves automatic optimization without proportionally increasing overall system complexity.

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

Solution Approach 2:

The system performs preliminary determination of optimal print settings before the actual printing process. By pre-calculating and pre-determining the best settings based on the print job characteristics, the system simplifies the user interface while the complexity is contained in the background processing phase.

Inventive Principle:
Principle #10Preliminary action

3Loss of substance

If print settings are automatically optimized, then paper waste is reduced, but loss of information about user preferences occurs

Engineering Contradiction:
Improvepaper wasteVSAvoiduser preference information
Core Design Contradiction:
Loss of substanceVSLoss of information

Solution Approach 1:

The notification unit provides feedback to users about the automatically determined settings, explaining how they save paper. This feedback loop maintains information transparency by informing users about the optimizations made, allowing them to understand the trade-offs and maintain awareness of their printing behavior patterns.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adapts to user responses to notifications. By monitoring whether users accept or modify the suggested settings, the system can learn and adapt to user preferences over time, maintaining both paper efficiency and user preference information through dynamic adjustment of its determination criteria.

Inventive Principle:
Principle #15Dynamics

AI summary

When a printer apparatus is allowed to execute a printing of a document using paper based on a print setting set by the user, the following processes are executed in order to allow the user to recognize a paper saving print setting. Whether or not there is a print setting which can save an amount of paper compared to the print setting set by the user is determined. If it is determined that a paper saving print setting exists, the user is notified of such a paper saving print setting.
