Solution Overview

Problem

Current home appliances with voice control and Bluetooth functions cannot be uniformly operated and controlled, limiting user convenience as they typically use traditional Bluetooth instead of MESH technology, preventing collaboration between voice and MESH technologies.

Innovation Solution

Integration of voice control technology with Bluetooth MESH network technology allows for remote control of all devices through voice instructions, using both local and online recognition for higher accuracy and faster responses, with only a WIFI device connected to the router, reducing router burden and enabling infinite propagation through broadcast packets, and employing automatic frequency hopping for adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional Bluetooth is used for device control, then device connectivity is achieved, but unified control of multiple home appliances cannot be realized

Engineering Contradiction:
Improveunified control capabilityVSAvoidmulti-device control scope
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent combines voice control technology with Bluetooth MESH network technology to create a unified control system. The voice control module receives voice instructions and converts them to control signals, while the Bluetooth MESH module enables multi-device connectivity through mesh networking, allowing single voice commands to control multiple appliances simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control system is designed with universal functionality to control various types of home appliances through a single interface. The system can handle different device types (lights, appliances, entertainment systems) through standardized voice commands and Bluetooth MESH communication protocols, making the control mechanism applicable across diverse device categories.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If all target devices are connected to the router, then comprehensive control is possible, but router burden increases significantly

Engineering Contradiction:
Improvecontrol accessibilityVSAvoidnetwork connection load
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent segments the network architecture into multiple components: a gateway device connected to the router, intermediate relay devices forming a Bluetooth MESH network, and target appliances. This segmentation allows devices to communicate through the mesh network without direct router connections, reducing router burden while maintaining control accessibility through the gateway.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gateway device serves as an intermediary between the router and the Bluetooth MESH network. It receives control commands from the router and relays them through the mesh network to target devices. Conversely, it collects device status information and forwards it to the router, eliminating the need for direct router connections to all devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If voice control instructions are processed locally only, then response speed is fast, but recognition accuracy is limited

Engineering Contradiction:
Improveresponse speedVSAvoidvoice recognition accuracy
Core Design Contradiction:
SpeedVSMeasurement precision

Solution Approach 1:

The system performs preliminary voice processing locally to extract key features and generate initial recognition results quickly. Simultaneously, it prepares and transmits voice data to the server for comprehensive analysis. This preliminary local action enables fast initial response while the server processing enhances accuracy, combining both speed and precision.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous dual-path processing: local voice recognition operates continuously for immediate response, while server-based recognition processes the same voice data continuously for high-accuracy verification. Both recognition paths operate simultaneously and continuously, with results integrated to provide both fast response and high accuracy.

Inventive Principle:
Principle #20Continuity of useful action
