Solution Overview

Problem

Existing wireless communication systems face challenges in managing efficient wireless connections when multiple electronic apparatuses are connected simultaneously, particularly in environments requiring large data transmission and reception, such as voice chat during gaming, where traditional solutions like cable connections are cumbersome and inefficient.

Innovation Solution

A communication device with multiple communication units of the same type, operating as either a master or slave, dynamically controls the operational state of these units based on communication situations to optimize connection management and load distribution, ensuring efficient data transfer and reception across multiple connected devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a plurality of electronic apparatuses are connected simultaneously via wireless communication, then communication capacity and versatility are improved, but communication load and interference between units increase

Engineering Contradiction:
Improvecapability to connect multiple electronic apparatusesVSAvoidcomplexity of managing wireless connections
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication device is divided into multiple independent communication units (first communication unit and second communication unit), each capable of independently establishing wireless connections with external apparatuses. This segmentation allows the system to handle multiple connections simultaneously without overwhelming a single communication unit, thereby improving the capability to connect multiple apparatuses while distributing the management complexity across separate units.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple communication units operate simultaneously, then communication capacity is improved, but frequency channel overlap and interference occur

Engineering Contradiction:
Improvedata transmission and reception capacityVSAvoidfrequency channel overlap and interference
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The control unit continuously monitors the communication situations of both communication units and dynamically adjusts their operational states based on real-time feedback. When interference or frequency channel overlap is detected, the control unit modifies the hopping frequency channels or operational parameters of the affected units to eliminate interference, thereby maintaining high data transmission capacity while preventing harmful frequency overlap.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control unit dynamically changes the operational states of the communication units based on current communication conditions. This includes adjusting hopping frequency channels, switching between master and slave modes, and modifying transmission parameters in real-time to optimize data transmission while avoiding interference with other units, thus resolving the contradiction between productivity and harmful frequency overlap.

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If a communication unit operates as slave continuously, then power consumption is reduced, but communication control flexibility is limited

Engineering Contradiction:
Improvepower consumption of communication unitVSAvoidcommunication control flexibility
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The control unit periodically switches the operational state of communication units between master and slave modes based on communication requirements. Rather than maintaining a fixed state, the system alternates roles as needed, allowing units to consume less power during slave periods while regaining control flexibility when switched to master mode, thus balancing energy efficiency with adaptability.

Inventive Principle:
Principle #19Periodic action

AI summary

A communication device is configured to wirelessly connect to an external apparatus. The communication device comprises a first communication unit and a control unit configured to control the first communication unit. The first communication unit is configured to operate as one of a master and a slave. When the first communication unit is connected to a given external apparatus, the control unit is configured to control a period during which the first communication unit operates as the slave in response to a communication situation of the first communication unit with a different external apparatus from the given external apparatus.
