Problem

Existing wireless communication devices for voice transmission are often one-way, prone to interference, require frequent maintenance, and lack mobility, making them inconvenient and costly for full-duplex communication.

Innovation Solution

A full-duplex wireless voice broadcasting apparatus with channel-changing and interference-resistance capabilities, comprising an emitting device and a receiving device connected through ZigBee modules, which periodically emit and receive data packages, allowing for automatic channel switching and energy-efficient two-way communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If one-way wireless microphones are used, then wireless mobility is achieved, but interference from noise and device reliability worsen

Engineering Contradiction:
Improvewireless mobilityVSAvoidinterference resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines transmitting and receiving functions into a single full-duplex device, merging previously separate one-way transmission and reception systems. This integration enables simultaneous two-way communication while maintaining wireless mobility and improving interference resistance through coordinated channel management.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system dynamically switches between frequency channels to avoid interference. The patent implements automatic channel selection and switching mechanisms that adapt to environmental conditions, allowing the device to maintain reliable communication by transitioning to cleaner channels when interference is detected.

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional microphones are replaced frequently, then voice quality is maintained, but maintenance cost and operational complexity increase

Engineering Contradiction:
Improvevoice qualityVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The full-duplex device performs self-diagnosis and automatic channel switching to maintain voice quality without requiring frequent manual intervention or replacement. The system monitors its own performance and autonomously adjusts operating parameters to preserve communication quality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes operational parameters such as frequency channel and transmission mode to maintain voice quality. By adjusting these parameters dynamically, the device preserves communication reliability without requiring physical replacement of components.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If positioning places for microphones are changed frequently, then coverage is optimized, but installation complexity and time increase

Engineering Contradiction:
Improvecoverage optimizationVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The full-duplex device serves multiple functions including transmission, reception, and automatic channel management in a single unit. This multi-functionality allows the device to adapt to various positioning scenarios without requiring separate equipment for different locations or configurations.

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

4Use of energy by moving object

If batteries are replaced regularly, then energy supply is maintained, but operational cost and downtime increase

Engineering Contradiction:
Improveenergy supplyVSAvoiddowntime for battery replacement
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system maintains continuous communication capability through automatic channel switching and full-duplex operation. By eliminating the need for battery replacement interruptions, the device ensures uninterrupted useful action while managing energy supply efficiently.

Inventive Principle:
Principle #20Continuity of useful action
