Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems struggle to display utterance histories in a manner that is easily viewable by users, especially when there are many histories, making it difficult for users to find the information they need.

Innovation Solution

A management apparatus and system that extracts relevant utterance histories based on user interests or device types and displays them in a distinguishable manner using a display device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all utterance histories are displayed by the display device, then the user can access complete information, but it becomes difficult for the user to check a specific utterance history when there are many histories

Engineering Contradiction:

Improvecompleteness of utterance history informationVSAvoidease of checking specific utterance history

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent segments the large set of utterance histories into smaller groups based on predetermined conditions such as device type, time period, or user interest. This segmentation allows the display device to present manageable portions of information rather than overwhelming the user with all histories at once, while still providing access to complete information through the management apparatus.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The management apparatus extracts specific utterance histories that match predetermined conditions from the complete set of all utterance histories. This extraction process identifies and presents only the relevant histories to the user, making it easier to find specific information without losing access to the complete dataset through the management system.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If utterance histories are filtered based on predetermined conditions, then specific histories become easier to find, but the quantity of information displayed is reduced

Engineering Contradiction:

Improveease of finding specific utterance historyVSAvoidquantity of displayed utterance histories

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The management apparatus acts as an intermediary between the complete utterance history database and the user's display device. It applies predetermined conditions to filter and select relevant histories, then transmits only those matching the conditions to the display device. This intermediary role enables efficient information retrieval while maintaining access to the full dataset through the management system.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Different sets of utterance histories are displayed with different qualities or characteristics based on local conditions. The system applies predetermined conditions to create customized views of utterance histories tailored to specific contexts, device types, or user interests, rather than presenting a uniform display for all histories.

Inventive Principle:

Principle #3Local quality

AI summary

A management apparatus includes: an extractor that extracts, on the basis of a predetermined condition, one or more utterance histories from a plurality of utterance histories each indicating the content of a voice caused to be output by a first device (e.g., utterance device); and a display controller that causes a second device (e.g., display device) to display information indicating the one or more utterance histories.
