Solution Overview

Problem

Existing electric toothbrush systems connected via BLUETOOTH often experience synchronization issues between displayed parameters and actual device settings, leading to inefficient control and a poor user experience when the BLUETOOTH connection is disconnected and then re-established.

Innovation Solution

An interactive control method that obtains connection information when the BLUETOOTH connection is established and displays the current operating parameters of the oral care device based on this information, ensuring that the user is informed of the actual device state and can control it efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the terminal displays operating parameters set when BLUETOOTH connection is disconnected, then the terminal can show parameters even without connection, but the displayed parameters are not synchronized with actual device parameters

Engineering Contradiction:

Improveparameter synchronizationVSAvoidcontrol efficiency

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The terminal establishes BLUETOOTH connection with the oral care device to obtain real-time operating parameters and displays these parameters to the user. This feedback mechanism ensures the displayed information accurately reflects the actual device state, resolving the synchronization issue between displayed and actual parameters.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The terminal proactively establishes BLUETOOTH connection with the oral care device before the user needs to control or view parameters, thereby obtaining and displaying the current operating parameters in advance. This preliminary action ensures parameter synchronization is maintained without waiting for user requests.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If the terminal establishes BLUETOOTH connection to obtain real-time parameters, then parameter synchronization is improved, but connection establishment time and system complexity increase

Engineering Contradiction:

Improveparameter accuracyVSAvoidconnection management

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The oral care device automatically sends its operating parameters to the terminal through BLUETOOTH connection without requiring manual intervention from the user. The device serves itself by maintaining connection and pushing parameter updates, reducing the complexity of connection management while ensuring accurate parameter display.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If the terminal displays outdated operating parameters, then display stability is maintained, but user control accuracy deteriorates

Engineering Contradiction:

Improvedisplay stabilityVSAvoidparameter accuracy

Core Design Contradiction:

Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The terminal periodically establishes BLUETOOTH connection with the oral care device to refresh and update the displayed operating parameters. This periodic action maintains display stability by systematically updating information at regular intervals while ensuring parameter accuracy through repeated synchronization cycles.

Inventive Principle:

Principle #19Periodic action

AI summary

An interactive control method includes: obtaining, by a terminal, connection information in a case that an oral care device and the terminal are connected to each other via BLUETOOTH; and displaying, by the terminal, current operating parameters of the oral care device based on the connection information. The connection information includes operating parameters of the oral care device when terminal is connected to the terminal via the BLUETOOTH.
