Solution Overview

Problem

Current wireless headphones lack the ability to efficiently share audio content among multiple devices while maintaining connectivity with a single audio source, and they do not offer advanced features for controlling the aural environment effectively.

Innovation Solution

The development of HEDphone technology, which utilizes the HEDtech protocol to create a wireless mesh network (HEDmesh) allowing multiple HEDphones to connect to a single audio source via Bluetooth or cable, and incorporates Super Human Hearing (SHH) features that enable users to control their aural environment by selectively amplifying or attenuating frequencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple wireless headphones connect to a single audio source simultaneously, then audio sharing capability is improved, but connection complexity and signal management become problematic

Engineering Contradiction:
Improveaudio sharing capabilityVSAvoidconnection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the audio distribution system into a master headphone unit and slave headphone units. The master unit maintains the primary connection to the audio source and manages the audio stream, while slave units connect to the master unit rather than directly to the audio source. This segmentation resolves the contradiction by enabling multiple headphones to share audio without each unit needing to independently manage complex connections to the audio source.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If wireless headphones provide advanced aural environment control, then user control capability is improved, but device complexity increases

Engineering Contradiction:
Improveaural control capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The master headphone unit serves multiple functions: it acts as a wireless headphone for the user, serves as an audio distribution hub for slave units, and functions as a control node for the HEDmesh network. By consolidating these multiple functions into a single device, the patent enables advanced aural control capabilities without requiring each individual headphone unit to be independently complex.

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

3Productivity

If a wireless mesh network is created for audio sharing, then audio sharing efficiency is improved, but network management complexity increases

Engineering Contradiction:
Improveaudio sharing efficiencyVSAvoidnetwork management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The master headphone unit acts as an intermediary in the HEDmesh network, receiving audio from the audio source and redistributing it to slave units. This intermediary role simplifies network management because slave units only need to communicate with the master unit rather than managing direct connections to the audio source or coordinating with each other. The master unit handles all network management complexity centrally.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention provide a method and system of audio sharing aimed to revolutionize the way people listen and share music and to give multiple uses to a wireless headphone referred to as HEDphone. A communication protocol referred to as HEDtech protocol is used in a HED system to allow users to share music amongst a plurality of HEDphones while using a single audio source. A wireless connection is established between the HEDphone and a mobile device including an audio source while simultaneously having the capability of allowing other HEDphone users to join wirelessly and listen to the same audio source. A feature of Super Human Hearing (SHH) goes beyond conventional ANR (ambient noise reduction) with additional features that allow the user to control their aural environment by being able to directionally increase or decrease selective frequencies.
