Solution Overview

Problem

Existing TWS earphones face challenges in synchronizing data reception between the main and secondary earphones, leading to high power consumption and bandwidth usage due to inefficient Bluetooth connections and latency.

Innovation Solution

A communication method where the main earphone sends acknowledgment or interference information in specific slots to the audio source based on correct or incorrect data packet reception, allowing the secondary earphone to receive data without interaction, thereby optimizing power consumption and bandwidth usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the main earphone forwards audio data to the secondary earphone, then the secondary earphone can receive audio data, but the power consumption of the main earphone increases significantly

Engineering Contradiction:
Improvedata reception reliabilityVSAvoidmain earphone power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the audio data reception function into two independent paths: the main earphone receives data directly from the audio source, and the secondary earphone also receives data directly from the audio source. This segmentation eliminates the need for the main earphone to forward data to the secondary earphone, thereby reducing the main earphone's power consumption while ensuring both earphones receive audio data reliably.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The audio source is designed to perform multiple functions: it directly transmits audio data to both the main earphone and the secondary earphone simultaneously. This multi-functionality allows the secondary earphone to receive data independently without relying on the main earphone as an intermediary, reducing the main earphone's data processing burden and power consumption.

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

2Reliability

If the main earphone forwards audio data to the secondary earphone, then the secondary earphone can receive audio data, but excessive bandwidth is consumed

Engineering Contradiction:
Improvedata reception reliabilityVSAvoidbandwidth consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent segments the data transmission path into two direct connections: audio source to main earphone, and audio source to secondary earphone. This eliminates the intermediate forwarding step that would consume additional bandwidth, while ensuring both earphones receive complete audio data directly from the source.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the main earphone forwards audio data to the secondary earphone, then the secondary earphone can receive audio data, but there is a large latency

Engineering Contradiction:
Improvedata reception reliabilityVSAvoiddata transmission latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates two independent direct transmission paths from the audio source to each earphone, eliminating the intermediate forwarding step. This segmentation removes the additional time required for the main earphone to process and forward data to the secondary earphone, thereby reducing latency while ensuring both earphones receive data reliably.

Inventive Principle:
Principle #1Segmentation

4Reliability

If both earphones send acknowledgment information when data is received correctly, then the audio source can confirm successful reception, but the communication complexity increases

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidcommunication protocol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the acknowledgment function into a unified mechanism where the main earphone sends acknowledgment information on behalf of both earphones when both receive data correctly. This combining of acknowledgment functions simplifies the communication protocol by reducing the number of separate acknowledgment messages needed, thereby reducing communication complexity while maintaining transmission reliability.

Inventive Principle:
Principle #5Merging (Combining)

5Reliability

If the secondary earphone sends interference information when data is not received correctly, then the audio source can resend data, but the communication protocol becomes more complex

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidcommunication protocol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses the main earphone as an intermediary in the acknowledgment process. When the secondary earphone fails to receive data correctly, it sends interference information that is processed through the established protocol framework. This intermediary approach allows the system to handle errors systematically without requiring complex peer-to-peer error handling between earphones, thereby managing protocol complexity while ensuring transmission reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present disclosure provides a TWS earphone communication method and system, and TWS earphones. The method includes: when an audio source sends a data packet and a main earphone correctly receives the data packet, the main earphone sends acknowledgment information in an acknowledgment information slot; when the data packet is incorrectly received by the main earphone, no information is sent in the acknowledgment information slot; and when the data packet is received correctly by a secondary earphone, the secondary earphone does not send any information in the acknowledgment information slot. When the data packet is not received correctly by the secondary earphone, it sends interference information in the acknowledgment information slot.
