Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless headphones are either cumbersome due to cords or large in size, and lack the ability to seamlessly transition between ad hoc and infrastructure wireless networks, limiting their usability and convenience.
Innovation Solution
A wireless earphone design that includes a transceiver circuit capable of receiving streaming audio via ad hoc and infrastructure wireless networks, automatically transitioning between them without user intervention, and connecting to a host server for continuous audio playback when out of range with the data source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless headphones use ad hoc network only, then direct connection is achieved, but connectivity is lost when out of range
Solution Approach 1:
The wireless headphone device is designed to support multiple network communication modes (ad hoc network and infrastructure network) within a single device, enabling it to adapt to different connectivity scenarios. The device can switch between direct peer-to-peer communication and infrastructure-mediated communication, making it universally applicable across various usage situations.
Solution Approach 2:
The system dynamically transitions between different network modes based on availability and suitability. The headphone device monitors network conditions and automatically switches from ad hoc mode to infrastructure network mode when appropriate, providing dynamic adaptability to maintain connectivity reliability.
2Reliability
If wireless headphones support multiple network modes, then connectivity reliability improves, but device complexity increases
Solution Approach 1:
The patent combines multiple network communication functionalities (ad hoc transceiver and infrastructure network transceiver) into a single integrated transceiver circuit. This merging approach maintains connectivity reliability through multi-mode support while reducing overall device complexity by sharing common components and control logic.
3Ease of operation
If cordless headphones are designed, then convenience improves, but audio quality and connectivity stability deteriorate
Solution Approach 1:
The infrastructure network (wireless access point and network server) serves as an intermediary that relays audio data between the data source and the headphone device. This mediator approach maintains audio streaming reliability over extended distances while preserving the convenience of cordless operation, as the infrastructure network handles the complex routing and data transmission.
Data Source
AI summary
Apparatus comprises adapter and speaker system. Adapter is configured to plug into port of personal digital audio player. Speaker system is in communication with adapter, and comprises multiple acoustic transducers, programmable processor circuit, and wireless communication circuit. In first operational mode, processor circuit receives, via adapter, and processes digital audio content from personal digital audio player into which adapter is plugged, and the multiple acoustic transducers output the received audio content from the personal digital audio player. In second operational mode, wireless communication circuit receives digital audio content from a remote digital audio source over a wireless network, processor circuit processes the digital audio content received from remote digital audio source, and the multiple acoustic transducers output the audio content received from the remote digital audio source.
