Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If short-range communication (Bluetooth) is used to send initialization data to smart home, then initialization can be completed, but strict requirements for hardware version and transmission distance are imposed
Solution Approach 1:
The patent replaces the mechanical/protocol-based Bluetooth short-range communication system with an acoustic wave-based communication system. The initialization data is transmitted through audio signals that can be received by the smart home device's microphone, eliminating the need for Bluetooth hardware compatibility and expanding adaptability to devices with varying hardware versions.
Solution Approach 2:
The patent changes the transmission medium parameter from electromagnetic waves (Bluetooth) to acoustic waves (audio signals). This parameter change allows the system to bypass hardware version requirements and distance limitations, as acoustic signals can be transmitted through the air to devices within audible range without requiring specific radio frequency compatibility.
2Reliability
If short-range communication (Bluetooth) is used to send initialization data to smart home, then initialization can be completed, but transmission distance is limited
Solution Approach 1:
The patent substitutes the electromagnetic wave transmission system (Bluetooth) with an acoustic wave transmission system. Acoustic waves can propagate through air over longer distances compared to Bluetooth signals, especially when transmitted through structured audio signals that can be amplified and directed, thereby increasing the effective transmission distance for initialization data.
3Adaptability or versatility
If voice recognition is used for initialization, then hardware and distance requirements are reduced, but voice recognition accuracy must be ensured
Solution Approach 1:
The patent applies local quality by preprocessing the audio signal to enhance the specific characteristics of the initialization voice command. The system focuses on extracting and analyzing only the relevant portions of the audio signal that contain the encoded initialization data, filtering out background noise and irrelevant sounds to ensure accurate recognition despite the reduced hardware requirements.
Data Source
AI summary
The disclosure relates to an initialization method for the smart home and the device thereof. The method includes receiving an initialization audio signal played by a target device, wherein the initialization audio signal is an audio signal of target characters obtained by encoding source data of initialization data for the smart home; decoding the initialization audio signal based on pre-stored correspondences between pre-set characters and source data of the pre-set characters so as to obtain the source data of the initialization data, wherein the pre-set characters include at least the target characters; and initializing the smart home based on the source data of the initialization data.
