Solution Overview

Problem

Conventional learning support systems do not facilitate the efficient sharing of multiple files or assignments between terminals, lacking a clear method for simultaneous distribution and display of multiple files on student terminals.

Innovation Solution

A server system that processes file sharing by displaying one file upon detection of an operation, listing multiple files when determined for sharing, and allowing selection and display of these files on connected terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple files are shared simultaneously from the staff terminal, then the productivity of file distribution is improved, but the device complexity of the system increases

Engineering Contradiction:
Improvefile distribution efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the file sharing process into distinct phases: file selection phase where multiple files are chosen, transmission phase where files are sent, and display phase where files are presented individually or as a list. This segmentation allows the system to handle multiple files efficiently without overwhelming complexity, as each phase manages a specific aspect of the multi-file sharing process

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension in file display by providing two distinct display modes: individual file display and file list display. This dimensional change allows the system to accommodate different user needs when receiving multiple files, improving productivity while maintaining manageable system complexity through flexible presentation options

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

2Ease of operation

If one file is displayed immediately upon sharing, then the ease of operation is improved, but the loss of information occurs when multiple files need to be shared

Engineering Contradiction:
Improvefile access convenienceVSAvoidfile selection context
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements dynamic display behavior that adapts based on the number of files being shared. When one file is shared, the system displays it immediately for easy access. When multiple files are shared, the system dynamically switches to list display mode to preserve context. This dynamic adaptation resolves the contradiction by making the system flexible rather than static

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides feedback to the user about the sharing state by displaying a file list when multiple files are shared, giving users context about what files are available. This feedback mechanism prevents information loss while maintaining ease of operation, as users can see the complete set of shared files and select what they need

Inventive Principle:
Principle #23Feedback

AI summary

A server (10) according to an embodiment includes a processor (11) that performs a process of, in response to an operation for sharing one or more files in a terminal (20T) connected via a network (N) being detected, displaying, in response to one file of the one or more files being determined to be shared, the one file (NBs2) on a display unit (27) of another terminal (20S) connected via the network (N) with the one file opened, and displaying, in response to two or more files of the one or more files being determined to be shared, a file list (LNBs) containing the two or more files on the display unit (27) of another terminal (20S).
