Solution Overview

Problem

Existing systems do not adequately allow users to select their preferred method of outputting electronic data, particularly in shared output apparatuses, and do not support touchless printing of reserved jobs.

Innovation Solution

An information processing system that allows users to register print jobs remotely through a user terminal, associate them with a unique identifier, and authenticate the output apparatus using short-range wireless communication to print reserved jobs without direct interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users directly operate the shared output apparatus to select and print electronic data, then printing functionality is achieved, but user convenience deteriorates due to required physical contact and interaction with shared device

Engineering Contradiction:
Improveuser convenienceVSAvoidoperational interaction requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a portable terminal as an intermediary device between the user and the shared output apparatus. The terminal displays a list of reserved print jobs and allows users to select which job to print without touching the shared output apparatus. The terminal acts as a mediator that handles the selection interface, while the output apparatus only needs to receive the selection result and execute printing, thus improving user convenience while maintaining system simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by having users reserve print jobs in advance through their portable terminals before approaching the shared output apparatus. When users arrive at the output apparatus, they only need to authenticate and select from pre-loaded job lists displayed on their terminals, rather than managing the entire printing workflow at the shared device. This preliminary preparation reduces the complexity of interaction required at the shared apparatus

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If users authenticate and select jobs at the shared output apparatus, then printing is enabled, but user convenience worsens due to lack of touchless operation capability

Engineering Contradiction:
Improvetouchless operationVSAvoidauthentication and job selection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The portable terminal serves as an intermediary that enables touchless operation at the shared output apparatus. Users can view job lists and make selections on their personal terminals using familiar interfaces, then transmit the selection result to the output apparatus wirelessly. This separates the complex interaction requirements from the shared apparatus, allowing touchless operation while maintaining reliable job selection through the terminal's display and input interface

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a copy of the job selection interface on the user's portable terminal, mirroring the functionality needed for job selection without requiring physical interaction with the shared output apparatus. The terminal displays a replicated view of available print jobs and selection controls, allowing users to complete the selection process remotely and wirelessly, thus enabling touchless operation while preserving the reliability of the selection process

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If the system provides comprehensive job selection interface at the output apparatus, then job selection flexibility is improved, but device complexity increases due to additional display and input requirements

Engineering Contradiction:
Improvejob selection flexibilityVSAvoidoutput apparatus structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex job selection interface functionality from the shared output apparatus and relocates it to the user's portable terminal. The output apparatus is reduced to providing authentication capabilities and receiving selection results, while the terminal handles displaying the complete job list, allowing users to view job details, and managing the selection process. This extraction maintains full job selection flexibility while significantly simplifying the output apparatus structure

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The portable terminal leverages its existing multi-functional capabilities (display, wireless communication, input interface) to provide the comprehensive job selection interface that would otherwise require dedicated hardware at the output apparatus. By using the terminal's universal functions for job selection, the system achieves flexible job selection without adding specialized components to the output apparatus, thus avoiding increased device complexity

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