Solution Overview

Problem

In environments with multiple artificial intelligence devices, users face difficulties in selecting the intended device to control via voice commands, as existing technologies rely on device proximity without considering status information, leading to potential activation of undesired devices.

Innovation Solution

An artificial intelligence device equipped with a microphone for receiving voice commands, a communication unit for wireless communication with slave devices, and a processor to determine the intended device based on the voice command intention and status information of both the device and slave devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple artificial intelligence devices are deployed in a house, then voice recognition coverage and service availability are improved, but device selection accuracy deteriorates because it becomes unclear which device should be controlled

Engineering Contradiction:

Improvevoice recognition coverageVSAvoiddevice selection accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies local quality by making each AI device have unique identifiable characteristics (device names, status information, characteristic information) so that while multiple devices provide broad coverage, each can be precisely identified and selected based on its local properties. This resolves the contradiction by enabling both widespread deployment and precise selection.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces additional dimensions for device identification beyond spatial proximity, including device name dimension, status information dimension, and characteristic information dimension. This multi-dimensional approach allows accurate device selection even when multiple devices are present, resolving the contradiction between coverage and selection accuracy.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If device selection is based only on distance from user, then selection process is simple, but selection accuracy deteriorates because the closest device may not be the desired device

Engineering Contradiction:

Improveselection process simplicityVSAvoiddevice selection accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent changes the selection parameters from solely spatial distance to include device name, status information, and characteristic information. This allows the system to maintain simple operation through automated multi-parameter evaluation while achieving high selection accuracy by considering multiple dimensions of device identification.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system uses feedback from multiple information sources (device names, status information, characteristic information) to determine the most appropriate device. This feedback mechanism enables accurate device selection without increasing operational complexity for the user, as the system automatically processes these parameters.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If device selection considers multiple factors (distance, status information, characteristic information), then device selection accuracy is improved, but processing complexity increases

Engineering Contradiction:

Improvedevice selection accuracyVSAvoidprocessing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by having devices pre-register their names, status information, and characteristic information before selection is needed. This pre-processing of identification data reduces the complexity of the selection process, as the system only needs to query and compare pre-existing information rather than gathering it in real-time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Each AI device maintains its own identification information (device name, status, characteristics) and can provide this information on demand. This self-service approach distributes the information management burden, reducing the processing complexity for the central selection system while maintaining high selection accuracy.

Inventive Principle:

Principle #25Self-service
