Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many wireless devices lack an interface and display to facilitate configuration for wireless communication, making it difficult to connect to wireless local area networks (WLANs), especially when multiple WLANs overlap and require unique identifiers and authentication keys.
Innovation Solution
A method and device using a mobile device with an audio port to transmit wireless configuration data, including a unique identifier and authentication key, to a wireless device via an audio cable, enabling the wireless device to connect to a WLAN without a display or input interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wireless device is designed without a display and input interface to reduce complexity and cost, then manufacturing cost and device simplicity are improved, but the ability to configure the device for wireless communication deteriorates
Solution Approach 1:
The patent uses a mobile device as an intermediary to perform the configuration function. The mobile device displays WLAN information and receives user input, while the wireless device without display/interface only needs to send and receive data through audio ports. This mediator approach allows the simple wireless device to be configured indirectly through the mobile device's interface.
Solution Approach 2:
The patent replaces the traditional mechanical/display-based configuration interface with an acoustic/audio-based communication system. Instead of using a display and physical input interface, the system uses audio ports and sound wave modulation to transmit configuration data, substituting a mechanical/optical system with an acoustic one.
2Adaptability or versatility
If configuration data is transmitted through audio ports instead of dedicated data ports, then device versatility is improved, but transmission reliability deteriorates
Solution Approach 1:
The patent changes the operational parameters of the audio port by using different audio frequencies to encode different types of data. Configuration data is transmitted using specific frequency ranges, while audio playback uses different frequency ranges. This parameter differentiation allows a single audio port to reliably handle multiple functions without interference.
Solution Approach 2:
The system uses periodic audio signals with specific timing patterns to transmit configuration data. By using structured, periodic transmissions rather than continuous signals, the system can reliably distinguish configuration data from other audio operations and ensure accurate data reception despite using a shared audio port.
Data Source
AI summary
Described herein are methods and devices for configuring a wireless device using audio data that is transmitted from a mobile device to the wireless device via a wired connection. For example, wireless configuration data may be sent from an audio port of the mobile device to an audio port of the wireless device while the mobile device and the wireless device are temporarily connected via an audio cable. According to an example method, a mobile device may determine wireless configuration data associated with a wireless local area network. The mobile device may then send the wireless configuration data to a wireless device via an audio port of the mobile device, such that the wireless device may be configured to access the wireless local area network.
