Innovation Solution
A data communication method where data packets are formatted according to a network access protocol with a header including a data length field, allowing data to be assigned and encrypted, then sent over a wireless network to a receiver device, which can decrypt and retrieve the data using the same format, enabling efficient data transfer without the need for additional communication modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peripheral communication components (Bluetooth, NFC) are integrated into electronic devices, then communication capability is improved, but device cost increases
Solution Approach 1:
The patent makes the existing wireless network interface card perform multiple functions: not only standard network communication but also direct data transmission to receiver devices. By encoding data in packet headers and utilizing the existing wireless interface, the system eliminates the need for separate peripheral communication components while maintaining communication capability.
2Adaptability or versatility
If peripheral communication components are added to enable data transfer, then data transfer capability is improved, but device complexity increases
Solution Approach 1:
The existing wireless network interface card is made multi-functional by implementing a data transfer method that uses packet header fields for direct communication. This approach allows the same hardware component to handle both traditional network traffic and direct device-to-device data transfer, thereby improving data transfer capability without increasing device complexity.
3Ease of manufacture
If data is transmitted using existing wireless networks without peripheral components, then device cost is reduced, but data delivery efficiency may be worsened
Solution Approach 1:
The patent segments data into multiple packets and utilizes header fields (such as data length fields) to encode additional information. This segmentation approach allows efficient data delivery by leveraging existing network infrastructure while maintaining cost-effectiveness through the intelligent use of packet structure.
Solution Approach 2:
The patent changes the parameter usage of existing data packets by repurposing header fields (like data length fields) to carry additional data. This parameter change enables more efficient data delivery through existing wireless networks without requiring additional hardware, thereby maintaining cost-effectiveness while improving delivery efficiency.
Data Source
AI summary
This application discloses a data communication method implemented at an electronic device. The electronic device obtains a sequence of data packets. Each data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective data packet. Data are then assigned to the data length fields of the sequence of data packets according to a second data format. The electronic device encrypts the sequence of data packets including the assigned data. The encrypted data packets are then sent to a receiver device that is communicatively coupled to the electronic device via a wireless network. The receiver device is configured to retrieve the assigned data from the data length fields of the data packets according to the first and second data formats and perform operations in accordance with the retrieved data.
