Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Air purifiers with voice reporting functions face challenges in prioritizing and effectively communicating high-priority state information to users when multiple utterance texts are available.

Innovation Solution

An air purifier equipped with an apparatus state detection unit, an utterance text extraction unit, and an utterance control unit that extracts and utters high-priority utterance texts in descending order of priorities assigned to categories, ensuring that critical information is reliably communicated to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple utterance texts are used to report different states of the air purifier, then the information completeness is improved, but the reliability of reporting high-priority information deteriorates due to lack of prioritization

Engineering Contradiction:

Improveinformation completenessVSAvoidreliability of high-priority information reporting

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The utterance texts are segmented into multiple categories (e.g., alarm category, notification category, information category), each assigned a different priority level. This segmentation allows the system to maintain comprehensive information coverage while enabling prioritized processing through category-based classification.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A priority parameter is introduced to categorize and rank different utterance texts. By assigning priority values to different categories of utterance texts, the system transforms the unprioritized set of multiple utterance texts into a structured hierarchy, ensuring high-priority information is reliably reported first.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If multiple utterance texts are uttered simultaneously, then the information delivery speed is improved, but the user's ability to understand critical information deteriorates due to information overload

Engineering Contradiction:

Improveinformation delivery speedVSAvoiduser understanding

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary sorting and prioritization of utterance texts before delivery to the user. By pre-organizing multiple utterance texts according to their priority levels and categories, the system ensures that critical information is delivered first, maintaining fast information delivery while preventing user confusion through structured presentation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The utterance delivery is made dynamic through sequential output based on priority levels. Instead of simultaneous delivery, the system adaptively sequences the utterance texts from high priority to low priority, allowing the delivery speed to be optimized while maintaining user comprehension through hierarchical presentation.

Inventive Principle:

Principle #15Dynamics

AI summary

An uttered utterance text that is a high priority text to be reported to a user is uttered reliably. The air purifier (10) includes an utterance text extraction unit (11a) that extracts an utterance text associated with an apparatus state and an utterance control unit (11b) that causes the utterance text extracted by the utterance text extraction unit (11a) to be uttered in descending order of priorities assigned to categories including the utterance text according to one of the priorities that is assigned to one of the categories that includes the utterance text.
