Wireless Microphone Mode Switching for Multi-User Voice Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless microphone systems require additional equipment for voice transmission and recording, and are limited to one-to-one configurations, making them impractical for multiple photographers capturing multiple subjects.
Innovation Solution
A wireless microphone system with a transmitter and receiver that alternates between data transmission and reception modes, allowing direct communication and recording without additional equipment, and supports multiple user configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional communication means or recording means are used for voice transmission and recording, then voice transmission and recording functions are achieved, but broadcasting production costs increase and equipment operation becomes complicated
Solution Approach 1:
The patent combines the communication means and recording means into the existing wireless microphone transmitter and receiver system. The transmitter can operate in both microphone mode (receiving voice) and communication mode (transmitting voice to receiver), while the receiver can operate in both receiving mode and recording mode, eliminating the need for separate equipment
Solution Approach 2:
The wireless microphone transmitter and receiver are designed with multi-functional capabilities. The transmitter can function as both a traditional microphone transmitter and a communication device for sending voice to the receiver. The receiver can function as both a traditional receiver and a recording device, allowing a single device to perform multiple roles
2Reliability
If wireless microphone transmitters and receivers are configured in one-to-one or many-to-one correspondence, then stable communication is achieved, but the system cannot be used when multiple photographers need to photograph one person or multiple persons simultaneously
Solution Approach 1:
The patent implements dynamic mode switching capability where the transmitter and receiver can alternately switch between data transmission mode and data reception mode. This dynamic operation allows the system to adapt to different user configurations (one-to-one, many-to-one, one-to-many, or many-to-many) while maintaining stable communication through structured time-division multiplexing
Solution Approach 2:
The system uses periodic time-division multiplexing where data transmission periods and reception waiting periods are alternately repeated. This periodic structure allows multiple transmitters and receivers to share the communication channel efficiently, enabling flexible multi-user configurations while maintaining communication stability through regular time-slot allocation
