Solution Overview

Problem

In public or commercial spaces, audio sources like TVs and radios are often kept at low volumes or turned off to minimize disturbance, making it inconvenient for users to listen to programming without adjusting the volume or moving closer, and existing technologies do not effectively facilitate wireless reception of digital audio streams across personal area networks.

Innovation Solution

A method and device that enable a wireless network mobile computing device to discover and facilitate the reception of digital audio streams from wireless network audio broadcast devices over a wireless personal area network, allowing direct connection or acting as a forwarding agent between the broadcast device and listening devices, based on current operating conditions and device capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If audio sources are kept at low volume or turned off in public spaces, then disturbance to customers is minimized, but user convenience to listen to programming deteriorates

Engineering Contradiction:
Improvedisturbance to customersVSAvoiduser convenience to listen
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system segments the audio reception function by introducing wireless listening devices that can independently receive and play audio streams from broadcast devices, separating the audio output from the display device and allowing individual volume control for each listening device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a wireless personal area network as an intermediary system that enables audio transmission from broadcast devices to listening devices without requiring physical proximity or volume adjustment of the source device, thus resolving the conflict between low-volume operation and user convenience.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If users move closer to the audio source to hear better, then audio quality improves, but user mobility and comfort deteriorate

Engineering Contradiction:
Improveaudio qualityVSAvoiduser mobility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system transitions audio transmission from a spatial proximity-based model to a wireless signal-based model, allowing users to receive audio quality equivalent to being near the source while maintaining freedom of movement throughout the space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If legacy listening devices are used that cannot receive broadcasts directly, then device compatibility is maintained, but wireless reception capability deteriorates

Engineering Contradiction:
Improvedevice compatibilityVSAvoidwireless reception capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The mobile computing device acts as an intermediary that receives the digital audio stream from the broadcast device and retransmits it to legacy listening devices, enabling these devices to function wirelessly without requiring direct broadcast reception capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a universal solution that works with both modern devices capable of direct broadcast reception and legacy devices that cannot, by providing multiple pathways for audio transmission through the wireless network infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)
