Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for conveying information to electronic devices, such as using Quick Response codes, face challenges like image-sensor displacement, focusing difficulties, poor lighting, and obscured codes, making the process cumbersome and time-consuming for users.
Innovation Solution
The technique involves using an audio signal with an audio sensor to receive an identifier from a remote device, which is then analyzed and sent to a pre-defined location via a network, allowing the device to perform an operation without user explicit action, using frequencies outside human auditory range and potentially including Universal Unique Identifiers or Quick Response codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual code capture methods (Quick Response codes) are used to convey information to electronic devices, then information can be transmitted, but the process becomes cumbersome and time-consuming due to image-sensor displacement, focusing difficulties, poor lighting, and obscured codes
Solution Approach 1:
The patent replaces the optical/mechanical image capture system with an acoustic signal reception system. Instead of using an image sensor to capture visual codes, the system uses an audio sensor to receive acoustic signals containing encoded information. This substitution eliminates the problems of image-sensor displacement, focusing difficulties, and lighting requirements, as acoustic signals are not affected by these factors.
Solution Approach 2:
The patent introduces an acoustic signal as an intermediary carrier for information transmission. Rather than direct visual code capture, the system uses acoustic signals to convey identification information from a first electronic device to a second electronic device. This intermediary approach allows information to be transmitted reliably without requiring precise visual alignment or optimal lighting conditions.
2Loss of information
If visual code capture methods are used, then information can be transmitted, but the process is time-consuming due to focusing and alignment requirements
Solution Approach 1:
The patent replaces the time-consuming mechanical focusing and alignment process with acoustic signal reception. The audio sensor can capture acoustic signals containing identification information without requiring focusing adjustments or precise alignment, significantly reducing the time needed to complete the information capture process while maintaining complete information transmission.
3Extent of automation
If audio signals outside human auditory range are used for information encoding, then information can be conveyed without user awareness, but the technique becomes more complex
Solution Approach 1:
The patent utilizes acoustic signals at frequencies outside the human auditory range (ultrasonic or subsonic frequencies) to encode identification information. This parameter change in frequency allows the system to automatically transmit information without user awareness or interaction. The receiving device processes these frequencies using standard audio signal processing techniques, managing the complexity through existing technology while achieving automatic operation.

Data Source
AI summary
During a communication technique, an electronic device receives an audio signal from a remote electronic device, such as another electronic device that is proximate to the electronic device. This audio signal may include information that specifies an identifier. The electronic device may analyze the audio signal to extract the identifier, and may provide the identifier to a pre-defined location via a network, such as a web page on the Internet. In response to providing the identifier, the electronic device receives the operation from the pre-defined location via the network. For example, the operation may include an instruction to open a document (such as a web page) on the network.
