Wireless Mobile Microphone Access via Back-End Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing public address systems in large conference or auditorium settings are inefficient as audience members have to wait for a wireless microphone to be passed manually, leading to time delays and potential oversight by the moderator.
Innovation Solution
A public address system utilizing wireless mobile communication devices as microphones, where a back-end system and wireless mobile communication devices with a microphone application enable access and transmission of audio signals through wireless protocols like Bluetooth or Wi-Fi, allowing audience members to request and receive connection authorization for speaking without manual microphone handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual microphone passing is used, then the moderator can control who speaks, but time delays are introduced and audience members may be overlooked
Solution Approach 1:
The patent replaces the mechanical system of manual microphone passing with an electronic/wireless system. Audience members use mobile devices to request microphones, and the system automatically manages allocation and audio transmission, eliminating the need for physical microphone handoff while maintaining moderator control through software-based arbitration.
Solution Approach 2:
The system enables audience members to self-serve by initiating microphone requests through their own mobile devices. The arbitration and allocation process occurs automatically without requiring manual intervention from conference assistants, reducing wait time while preserving moderator oversight capabilities.
2Ease of operation
If manual microphone passing is used, then equipment can be controlled, but the process becomes complex and inefficient
Solution Approach 1:
The patent makes audience members' existing mobile devices serve dual purposes: as communication devices and as wireless microphones. This eliminates the need for separate dedicated wireless microphone equipment while simplifying the access process, as users already possess and are familiar with using their mobile devices.
Solution Approach 2:
The patent extracts the microphone functionality from the physical wireless microphone device and relocates it to the audience member's mobile device. This separation allows the original wireless microphone system to be eliminated entirely, simplifying both the equipment inventory and the operational process.
3Productivity
If wireless mobile devices are used as microphones, then access time is reduced, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing communication channels between mobile devices and the audio system before speaking is needed. Connection authorization tokens are obtained in advance, and the arbitration system is pre-configured to handle requests, enabling instant microphone access without ad-hoc setup delays.
Solution Approach 2:
The patent introduces a back-end arbitration system as an intermediary that manages the complexity of wireless device integration. This intermediary handles connection authorization, audio signal routing, and conflict resolution between multiple users, shielding end users from the underlying system complexity while enabling rapid access.
