Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current wireless and wired voice communication systems are unable to maintain communication when network conditions are poor, leading to dropped calls and loss of voice media, as they rely on sufficient usable bit rate for real-time conversations, with no persistent storage of voice media.

Innovation Solution

Implementing a module for persistent storage of voice media on communication devices, allowing transmission at reduced bit rates when network conditions are inadequate, enabling communication beyond conventional range and capacity limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If persistent storage of voice media is implemented, then communication can continue when network conditions are poor, but device complexity increases

Engineering Contradiction:

Improvecommunication continuityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by storing voice media locally in persistent storage before network transmission is needed. This allows the voice media to be ready for transmission even when network conditions are poor or unavailable, ensuring communication continuity without requiring complex real-time network monitoring and dynamic switching mechanisms.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If voice media is transmitted at reduced bit rates, then network capacity is extended, but communication quality deteriorates

Engineering Contradiction:

Improvenetwork capacityVSAvoidcommunication quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system applies partial action by transmitting only essential portions of voice media at reduced bit rates when network capacity is constrained. The persistent storage contains the complete high-quality voice media, and the system transmits sufficient data to maintain communication functionality while accepting reduced quality, thereby extending network capacity utilization without requiring complex quality adjustment algorithms.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If live real-time communication is required, then communication quality is maintained, but network dependency increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidnetwork independence

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system extracts the dependency on real-time network connectivity by storing voice media locally in persistent storage. This allows the communication system to function independently of network conditions, as the voice media can be retrieved and transmitted from local storage even when network availability is poor or intermittent, thereby reducing network dependency while maintaining communication quality.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An application for gracefully extending the range and/or capacity of voice communication systems. The application includes a module for the persistent storage of voice media on a communication device as the voice media is created. When the usable bit rate on the network is poor and below that necessary for conducting live communication of the voice media, a transmit module transmits the voice media out of storage at or below the available usable bit rate on the network. Although latency may be introduced, the storage of transmitted media provides the ability to extend the useful range and/or capacity of the network when conditions on the network otherwise make live communication impossible or impractical.
