Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional learning support systems do not effectively handle the sharing of multiple files or assignments between terminals, leading to usability issues.

Innovation Solution

The learning support server facilitates the sharing of multiple files by displaying a notification for each file distribution and providing a highlighted list of unread files, allowing users to easily identify and open specific files.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple files are shared through conventional learning support systems, then file distribution capability is improved, but usability and ease of operation deteriorate due to lack of effective handling mechanisms

Engineering Contradiction:

Improvefile distribution capabilityVSAvoidusability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the file sharing process into distinct phases: notification phase (when files are shared) and access phase (when files are opened). By separating these functions and providing different display modes for single files versus multiple files, the system improves usability while maintaining versatile file distribution capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic display behavior that adapts based on the number of shared files. When one file is shared, it displays the file content directly; when multiple files are shared, it displays a file list with thumbnails. This dynamic adaptation resolves the contradiction by adjusting the interface to match the operational context

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If file sharing functionality is added to learning support systems, then functionality and versatility are improved, but system complexity increases

Engineering Contradiction:

Improvefile sharing functionalityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the existing display unit serve multiple functions: it displays both notification messages and file content or file lists depending on the context. This multi-functionality approach adds file sharing capability without requiring separate dedicated display components, thereby limiting the increase in system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The notification message serves as an intermediary element that bridges the file sharing function and the display function. It contains references to shared files and triggers appropriate display actions, allowing the system to handle file sharing through existing communication and display infrastructure without significant complexity increase

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A server according to an embodiment includes a processor that performs a process of, in response to an operation for sharing one or more files in a terminal connected via a network being detected, displaying, in response to one file of the one or more files being determined to be shared, the one file on a display of another terminal connected via the network 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 containing the two or more files on the display of another terminal.
