Solution Overview

Problem

Bluetooth connections are prone to signal loss or delay due to crosstalk or signal blockage, especially in confined spaces, leading to interrupted connections and adverse user experiences.

Innovation Solution

Establishing a hierarchical communication system that includes both direct and interconnection channels between mobile devices, allowing data to be transmitted through a main channel and a sub channel, with an additional interconnection between slave devices to act as a hub and maintain continuous data transmission even when primary connections are unstable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If signal power is increased to maintain connection, then connection stability is improved, but output power is limited for each Bluetooth version

Engineering Contradiction:
Improveconnection stabilityVSAvoidoutput power limit
Core Design Contradiction:
ReliabilityVSPower

Solution Approach 1:

The patent introduces a relay device as an intermediary component in the communication path. When the direct main channel experiences signal blockage or crosstalk, data can be transmitted through the relay device via sub channels, effectively bypassing the signal interference without requiring increased transmission power.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions from a single-dimensional direct connection to a multi-dimensional communication architecture by establishing both main channels (direct connection) and sub channels (relay connection). This dimensional expansion allows the system to overcome signal blockage by switching to alternative transmission paths in the network topology dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If direct connection is used between master and slave devices, then communication simplicity is improved, but signal blockage or crosstalk occurs in confined spaces

Engineering Contradiction:
Improvecommunication simplicityVSAvoidsignal stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the communication path into multiple independent channels: main channels for direct communication and sub channels for relay communication. This segmentation allows the system to maintain simple direct connections when possible while providing alternative segmented paths when signal blockage occurs, thus preserving both simplicity and reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The relay device performs multiple functions: it acts as a normal slave device for its own communication needs while simultaneously serving as a relay node for other slave devices. This multi-functionality enables the system to maintain communication simplicity without additional dedicated relay infrastructure while improving signal stability in confined spaces.

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

3Adaptability or versatility

If multiple wireless slave devices are connected to a single host device, then connectivity versatility is improved, but crosstalk or signal shadow region occurs

Engineering Contradiction:
Improveconnectivity versatilityVSAvoidsignal quality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces relay devices as intermediaries that mediate communication between multiple slave devices and the host device. When crosstalk or signal shadow regions occur due to multiple simultaneous connections, the relay devices provide alternative transmission paths that isolate interfering signals, thereby maintaining connectivity versatility while improving signal quality.

Inventive Principle:
Principle #24Intermediary (Mediator)
