Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low-frequency magnetic communication is used for range control and authentication, then security and range control are improved, but data transmission rate and access rate deteriorate
Solution Approach 1:
The patent segments the communication process into two distinct phases: low-frequency magnetic communication for authentication and range control, and radio frequency communication for data transmission. This segmentation allows each communication mode to operate in its optimal performance zone, with low-frequency providing secure authentication and high-frequency providing fast data transfer.
Solution Approach 2:
The patent introduces radio frequency communication as an intermediary channel that bridges the authentication phase and data transmission phase. After low-frequency magnetic communication completes authentication, the system switches to radio frequency communication for subsequent data exchange, thereby overcoming the low data transmission rate limitation of low-frequency magnetic communication.
2Adaptability or versatility
If low-frequency magnetic communication is used for authentication, then range control capability is improved, but transaction time increases
Solution Approach 1:
The patent performs authentication and range control checks using low-frequency magnetic communication as a preliminary action before switching to radio frequency communication for the main transaction. By completing the time-consuming authentication process first and then transitioning to faster radio frequency communication, the system minimizes the impact on overall transaction time.
Solution Approach 2:
The patent implements a dynamic communication mode switching mechanism that transitions from low-frequency magnetic communication to radio frequency communication based on the transaction stage. This dynamic adaptation allows the system to leverage the strengths of each communication mode at different phases, optimizing both range control and transaction speed.
3Device complexity
If existing low-frequency magnetic communication systems are used without encryption, then device complexity is reduced, but data security deteriorates
Solution Approach 1:
The patent merges low-frequency magnetic communication and radio frequency communication into a unified hybrid system that leverages the security advantages of low-frequency authentication with the speed advantages of high-frequency data transmission. This combination allows the system to implement encryption and security protocols without significantly increasing overall system complexity.
Solution Approach 2:
The patent changes the communication parameters by switching between low-frequency and radio frequency modes, applying encryption primarily during the radio frequency data transmission phase. This parameter change allows the system to enhance data security without requiring encryption throughout the entire communication process, thereby controlling system complexity.

AI summary
The present invention deals with a method for accessing to radio frequency communication with low-frequency electromagnetic communication. The method includes: a request side sends an activation request including the first random data via a low frequency channel; a requested side receives the activation request, generates an activation response message including the second random data and an identifier of the requested side, and sends the activation response message according to the first radio frequency communication address; the request side receives and verifies the activation response message. If the verification is passed, the request side generates a connection request including the third random data, and sends the connection request according to the second radio frequency communication address; the requested side receives and verifies the connection request. If the verification is passed, the requested side generates a connection response message, and sends the connection response message according to the second radio frequency communication address; the request side receives the connection response message to verify whether the connection is successful. If the connection is successful, the request side trades with the requested side, according to the second radio frequency address, via a radio channel. The present invention accelerates the access speed of the radio frequency communication with low-frequency electromagnetic communication.
