Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices face inefficiencies in initialization due to strict hardware and distance requirements for short-range communication methods like Bluetooth, often resulting in failed data transmission and incomplete initialization.
Innovation Solution
An initialization method that uses an initialization audio signal encoded with source data, which is decoded using pre-stored correspondences to automatically initialize the smart device, eliminating the need for strict hardware and distance requirements.

Engineering Contradiction Analysis
1Reliability
If short-range communication (Bluetooth) is used to send initialization data, then initialization can be completed, but strict requirements on hardware version and transmission distance are imposed
Solution Approach 1:
The patent replaces the mechanical/electronic short-range communication system (Bluetooth) with an acoustic communication system using audible sound waves. The initialization data is transmitted through sound signals that can be captured by the device's microphone, eliminating the need for Bluetooth hardware compatibility and extending transmission distance beyond typical Bluetooth range limitations.
Solution Approach 2:
The patent changes the transmission medium parameter from electromagnetic waves (Bluetooth) to acoustic waves (sound). This parameter change allows the system to bypass Bluetooth protocol version requirements and distance limitations, as acoustic waves can propagate over longer distances and do not require specific hardware version compatibility.
2Reliability
If short-range communication is used to send initialization data, then data can be transmitted, but transmission distance is limited
Solution Approach 1:
The patent substitutes Bluetooth electromagnetic communication with acoustic wave transmission. Sound waves can travel much farther than typical Bluetooth range, allowing initialization data to be transmitted from distant locations without requiring the user to be within close proximity of the device.
3Reliability
If manual input of initialization data is used, then data can be entered, but input efficiency is low
Solution Approach 1:
The system automatically receives, decodes, and processes initialization data through acoustic signal capture. The device autonomously completes the initialization process by receiving sound waves containing encoded data, eliminating the need for manual typing or configuration input from the user, thereby dramatically improving input efficiency.
Solution Approach 2:
The patent replaces manual data input operations with automatic acoustic signal reception and decoding. Instead of requiring users to manually enter initialization parameters, the system captures sound waves containing the data and automatically processes them through pre-stored correspondence relationships, achieving rapid automated initialization.

AI summary
The disclosure relates to an initialization method for the smart device and the device thereof. The method includes: receiving an initialization audio signal played by a target device (S101), wherein, the initialization audio signal is the audio signal of the target characters obtained by encoding the source data of the initialization data for the smart device; decoding the initialization audio signal according to the pre-stored correspondences between the pre-set characters and a source data of the pre-set characters, so as to obtain the source data of the initialization data (SI02), wherein, the pre-set characters at least includes said target character; initializing the smart device according to the source data of the initialization data (S103). The technical solution can improve the input efficiency of the initialization data and automatically complete the initialization of the smart device through initializing the audio signal, without extra requirements on the hardware of the smart device and the target device as well as the communication distance.
