Solution Overview

Problem

Current wireless transceiving device systems face challenges in synchronizing data across multiple devices, leading to uneven load distribution and power consumption issues, particularly in scenarios like Bluetooth audio devices, where data transmission and synchronization are affected by the need for retransmission and unequal status among devices.

Innovation Solution

Establishing a wireless transceiving device group with a unified device group identifier allows for bidirectional connections between devices and a data source, ensuring equal status and balanced power consumption, even if one device fails, and enabling efficient data synchronization without the need for retransmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple wireless transceiving devices are connected to a data source device, then data synchronization capability is improved, but load distribution becomes uneven and power consumption increases

Engineering Contradiction:
Improvedata synchronization capabilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the wireless transceiving devices into a structured group with designated roles (group owner, group members) and establishes individual bidirectional connections between each device and the data source. This segmentation allows independent connection management and load distribution, preventing uneven power consumption patterns while maintaining synchronization capability across all devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements equipotentiality by establishing bidirectional connections between the data source and each wireless transceiving device, ensuring that all devices have equal status and communication rights. This eliminates hierarchical dependencies that cause uneven load distribution, allowing each device to consume power independently and efficiently without affecting others.

Inventive Principle:
Principle #12Equipotentiality

2Adaptability or versatility

If multiple wireless transceiving devices are connected to a data source device, then data synchronization capability is improved, but connection reliability decreases due to potential failures

Engineering Contradiction:
Improvedata synchronization capabilityVSAvoidconnection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the connection architecture into independent bidirectional links between the data source and each wireless transceiving device. This segmentation ensures that connection failures in one device do not propagate to other devices, as each has its own dedicated connection path, thereby maintaining overall system reliability while supporting multiple synchronized devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By implementing equal status for all wireless transceiving devices through bidirectional connections, the patent ensures that no single device acts as a critical bottleneck. Each device can independently establish and maintain connections, so the failure of one device does not compromise the connection reliability of others, thus improving overall system robustness.

Inventive Principle:
Principle #12Equipotentiality

3Device complexity

If traditional wireless connection methods are used, then device complexity is reduced, but data retransmission is required leading to synchronization delays

Engineering Contradiction:
Improveconnection method simplicityVSAvoidsynchronization delay
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent establishes bidirectional connections between the data source and each wireless transceiving device before data transmission begins. This preliminary connection setup ensures that all devices are ready to receive and synchronize data simultaneously, eliminating the need for retransmission and reducing synchronization delays without significantly increasing device complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms within the bidirectional connections to monitor data transmission status and ensure synchronization. This feedback allows the system to detect and correct synchronization issues in real-time without requiring retransmission, thereby reducing time loss while maintaining connection simplicity through standardized bidirectional communication protocols.

Inventive Principle:
Principle #23Feedback
