Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of building specialized conference rooms and acquiring advanced audio equipment makes it difficult to conduct effective meetings across various technical fields, as professionals often require high-quality voice enhancement solutions that are not readily available.
Innovation Solution
A voice enhancement method for distributed systems, where multiple picking devices communicate with each other to receive, transmit, and enhance voice signals through operations like beamforming, echo cancellation, and noise reduction, using wired or wireless transmission methods, including Bluetooth, Wi-Fi, and acoustic positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specialized conference rooms with sound-absorbing walls or microphone arrays with beamforming technology are built, then voice enhancement quality is improved, but cost increases
Solution Approach 1:
The system divides the voice enhancement function across multiple independent picking devices (mobile phones, tablets, or dedicated microphones) distributed in the space, rather than requiring a single specialized conference room setup. Each device independently captures and transmits voice information, which is then processed collectively to achieve enhancement without needing specialized infrastructure
Solution Approach 2:
The patent enables ordinary picking devices with standard communication capabilities to perform voice enhancement functions previously reserved for specialized equipment. By using widely available devices that everyone already possesses, the system eliminates the need for expensive specialized conference rooms while achieving comparable voice enhancement through distributed processing
2Manufacturing precision
If advanced audio equipment with beamforming technology is acquired, then voice signal quality is improved, but device complexity increases
Solution Approach 1:
The complex voice enhancement task is segmented across multiple simple picking devices, each performing basic voice capture and transmission. The sophisticated beamforming and noise reduction operations are distributed across the network of devices rather than concentrated in a single complex system, reducing the complexity burden on individual devices while maintaining overall system performance
Solution Approach 2:
The patent introduces a coordinate system and positioning mechanism as an intermediary layer that simplifies the interaction between multiple picking devices. By establishing spatial coordinates and device positions, the system enables straightforward coordination for voice enhancement without requiring complex direct device-to-device negotiation, thus reducing overall system complexity while achieving advanced audio processing
3Manufacturing precision
If specialized conference room equipment is deployed, then voice enhancement capability is improved, but adaptability to different locations decreases
Solution Approach 1:
The system dynamically adapts to different locations and environments by allowing flexible placement of picking devices wherever participants are located. The coordinate system and positioning mechanisms enable the system to automatically adjust to new spatial configurations, making the voice enhancement capability portable and adaptable to any meeting location rather than being fixed to specialized rooms
Solution Approach 2:
By using ordinary picking devices that participants already have (mobile phones, tablets), the system achieves voice enhancement capability in any location without requiring specialized infrastructure. The same devices can be used in conference rooms, home offices, coffee shops, or outdoor settings, providing universal adaptability across different environments
