Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used between anchors, then communication reliability is ensured, but device complexity and power consumption increase
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system between anchors. The wireless communication module transmits data frames using electromagnetic waves instead of physical cables, eliminating the need for complex cabling while maintaining communication functionality. This substitution resolves the contradiction by removing the mechanical connection requirement that caused device complexity.
Solution Approach 2:
The patent extracts the communication functionality from the wired system and implements it as an independent wireless communication module within each anchor. By taking out the communication function and implementing it separately through wireless means, the system eliminates the need for external cabling and power supply connections, thereby reducing device complexity while preserving reliability through protocol-level error handling.
2Stability of the object's composition
If wired communication with continuous power supply is used, then anchor operation is stable, but power consumption increases
Solution Approach 1:
The patent implements periodic action by allowing anchors to operate in sleep modes and wake up only when needed for communication or detection tasks. Instead of continuous power supply, anchors can enter low-power states and activate periodically or event-driven, significantly reducing power consumption while maintaining operational stability when active.
Solution Approach 2:
The patent enables anchors to be self-sufficient by integrating wireless communication modules that do not require external power supply connections. Each anchor can independently manage its power consumption through internal power management, eliminating the need for continuous external power supply while maintaining stable operation during active periods.
3Speed
If wireless communication is implemented without channel coding, then transmission speed is fast, but transmission reliability decreases
Solution Approach 1:
The patent applies preliminary action by performing channel coding on data frames before transmission. The encoding process adds redundancy bits to the data in advance, preparing the information for reliable transmission over the wireless channel. This preliminary processing ensures that even if transmission errors occur, the original data can be recovered, thus maintaining both speed and reliability.
Solution Approach 2:
The patent implements feedback mechanisms through acknowledgment frames and error detection codes. The receiving anchor sends feedback to the transmitting anchor to confirm successful reception or request retransmission. This feedback loop ensures transmission reliability while minimizing the impact on overall transmission speed through efficient error handling.

AI summary
Embodiments of this application relate to the vehicle field, and provide a communication method for anchors on a vehicle, an apparatus, and a computer-readable storage medium. The plurality of anchors are disposed on the vehicle, wireless communication is performed between the plurality of anchors, and the plurality of anchors include a first anchor and a second anchor. The communication method for the anchors on the vehicle includes: after a wireless connection is established between the first anchor and the second anchor, the first anchor transmits a first data frame with the second anchor, where channel coding is performed on the first data frame; and the first anchor transmits a first acknowledgement frame with the second anchor, where the first acknowledgement frame indicates whether the first data frame is correctly transmitted. The channel coding is performed on the data frame transmitted between the anchors, to ensure reliability of the wireless communication between the anchors. In addition, because the wireless communication is performed between the anchors, a power supply of the vehicle does not need to continuously supply power to the anchors, thereby reducing costs and power consumption of the vehicle.
