Solution Overview

Problem

Users face difficulties in selecting files for printing when multiple files are shared via communication tools like chat or web conferencing, requiring extensive searching and review of chat screens to find the desired file for printing.

Innovation Solution

An information processing system with a management unit to manage accessible files, a display unit to show a list of files based on access time, and an output unit to facilitate printing of user-selected files, enhancing the efficiency of file selection for printing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If files are shared via chat function or web conferencing function, then information sharing between users is enabled, but user effort and time required to select a file for printing increases

Engineering Contradiction:
Improvefile sharing capabilityVSAvoidtime to search and select file
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments the file selection process by creating a dedicated print candidate file list that separates printable files from other chat files. This list is displayed in a dedicated area, allowing users to quickly identify and select files for printing without searching through the entire chat history or message list.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by automatically generating and displaying a list of print candidate files before the user needs to print. The file list is prepared in advance with print buttons attached to each file, so when the user wants to print, the selection work is already done and presented in an organized manner.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If files are shared by multiple users via communication tools, then collaboration is enabled, but complexity of file selection process increases

Engineering Contradiction:
Improvemulti-user collaborationVSAvoidease of file selection
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the interface into distinct functional areas: a chat area for communication and a dedicated print candidate file list area for file selection. This segmentation allows users to focus on file selection in the dedicated area without the visual clutter and complexity of the multi-user chat interface, making the operation simpler despite multi-user collaboration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The print candidate file list acts as an intermediary between the chat function and the printing function. It mediates the complex multi-user file sharing by presenting a simplified, curated list of printable files with direct print buttons, bridging the gap between collaborative file sharing and individual printing needs.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If chat screen is reviewed to find file for printing, then file selection is possible, but operation time and user effort increase

Engineering Contradiction:
Improvefile selection capabilityVSAvoidtime to review chat screen
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-processing chat files to identify printable files and organizing them into a dedicated print candidate list before the user needs to print. This eliminates the need for users to manually review the chat screen, as the selection work is already completed by the system.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent adds another dimension to the interface by creating a separate spatial area for the print candidate file list, distinct from the chat area. This dimensional separation allows users to access file selection functionality without navigating through or reviewing the chat screen, significantly reducing the time and effort required for file selection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
