Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users often fail to notice changes in notification details or methods related to home appliances and services due to lack of effective notification mechanisms.

Innovation Solution

A voice notification system that includes a change detector, notifier, and person detector to provide voice notifications when changes in notification targets, devices, or voice settings occur, ensuring users are informed of these changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If notification changes are made regarding notification details or methods, then the system can provide updated information, but users may not notice the changes

Engineering Contradiction:

Improvenotification accuracyVSAvoiduser awareness of changes

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system implements a feedback mechanism where the notification management device actively detects notification changes and sends notifications to talking devices, which then announce these changes to users. This closed-loop feedback ensures users are informed of updates to notification details or methods, resolving the issue of users not noticing changes.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces traditional silent notification updates with acoustic communication through talking devices. Instead of relying on users to check for changes, the system uses voice announcements to communicate notification changes, making them audible and noticeable to users in their environment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If the system provides detailed notification information, then information completeness is improved, but device complexity increases

Engineering Contradiction:

Improvenotification detail completenessVSAvoidsystem structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The notification management device performs multiple functions: detecting notification changes, managing notification targets, controlling talking devices, and providing voice announcements. By consolidating these functions into a single universal device, the system achieves detailed notification information without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The talking device serves as an intermediary between the notification management device and the user. It receives notification change information from the management device and translates it into voice announcements, simplifying the interaction architecture while maintaining information completeness.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A voice notification system (1) is a system that causes a talking device to provide a voice notification of information about a notification target that is an information source device about which information is notified by the talking device or an information source service about which information is notified by the talking device. The system includes: a change detector (11) that detects a change regarding notification details or a change regarding a notification method; and a notifier (12) that causes the talking device to provide a voice notification of information about the change regarding the notification details or the change regarding the notification method when the change regarding the notification details or the change regarding the notification method is detected.
