Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing acoustic data transmission methods are impractical for legacy devices lacking network connectivity and are unsuitable for time-sensitive situations, such as transmitting receipts for payment transactions and delivering advertisements, due to the need for real-time network connections and the inability to implement audible content transfer.

Innovation Solution

The method involves superimposing relevant information onto an interfacing audio or video signal output by a source electronic device, allowing transfer to a recipient device without requiring a network connection, using ultrasonic sound signals or video modifications detectable by the recipient device but imperceptible to humans, and optimizing timing based on the content of the interfacing signal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If acoustic data transmission methods are used, then data can be transmitted between devices, but the method is impractical for legacy devices lacking network connectivity and unsuitable for time-sensitive situations

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoiddevice compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system enables data transmission through multiple interfaces (audio output, video output, display) that work across different device types including legacy devices without network connectivity. The source device can broadcast data through any available interfacing signal, making the system universally applicable across diverse electronic devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses an interfacing signal (audio, video, or display output) as an intermediary carrier to transmit data between devices. This intermediary approach allows data to be transmitted through signals that already exist in the system, avoiding the need for dedicated communication hardware and enabling compatibility with legacy devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If data is transmitted through audible content modification, then information can be conveyed to users, but it cannot be implemented for time-sensitive situations such as transmitting receipts for payment transactions

Engineering Contradiction:

Improveinformation delivery capabilityVSAvoiddata transmission time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system uses periodic modulation of the interfacing signal to encode data. By modulating the signal at specific frequencies and time intervals, data can be transmitted efficiently within time-sensitive contexts while maintaining synchronization with the original content flow.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system prepares and transmits data in advance within the interfacing signal before the user needs it. By embedding data in the outgoing signal stream proactively, the system ensures data is available immediately when needed, reducing perceived transmission time for time-sensitive operations.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If ultrasonic sound signals or video modifications are used, then data transfer is imperceptible to humans, but the complexity of the system increases

Engineering Contradiction:

Improveuser perceptibility of data transferVSAvoidsignal processing complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system changes parameters of existing interfacing signals (frequency, amplitude, timing) to encode data in ways that are imperceptible to humans. By modifying parameters within acceptable ranges for the original content, the system achieves invisible data transmission without requiring fundamentally new hardware or overly complex processing.

Inventive Principle:

AI summary

Introduced here are approaches to transferring relevant information from a first electronic device (also called a “source electronic device”) that is presently outputting an interfacing signal that is detectable by a second electronic device (also called a “recipient electronic device”) via modification of the interfacing signal. Such modification causes the relevant information to be appended to the interfacing signal and then transferred to the recipient electronic device. This can be accomplished by superimposing another signal that is representative of the relevant information onto the interfacing signal. Thus, the relevant information can be transferred from the source electronic device to the recipient electronic device by superimposing a signal onto the interfacing signal that is output by the source electronic device.
