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 due to cabling and continuous power supply requirements
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system. Anchors use wireless transceivers to communicate with the control system and each other, eliminating the need for physical cables and connectors. This substitution reduces cabling complexity while maintaining communication functionality through wireless protocols that provide reliable data transmission.
Solution Approach 2:
The patent extracts the power supply requirement from the anchor system. By using wireless communication, anchors no longer need continuous wired power supply connections. The system extracts the power delivery mechanism from the communication infrastructure, allowing anchors to operate with reduced power consumption and greater installation flexibility.
2Reliability
If wired communication interfaces are installed on anchors, then communication stability is improved, but manufacturing cost and installation complexity increase
Solution Approach 1:
The patent replaces mechanical wired interfaces with wireless communication modules on anchors. This eliminates the need for installing physical connectors, cable management systems, and associated hardware. The wireless approach simplifies manufacturing by removing mechanical components while maintaining stable communication through protocol-based error correction and data validation.
3Measurement precision
If anchors are arranged in different positions on the vehicle, then positioning accuracy is improved, but cabling design and installation become more complex
Solution Approach 1:
The patent uses wireless communication to enable anchors to be positioned anywhere on the vehicle without being constrained by cable routing. Anchors can be placed in optimal positions for positioning accuracy, such as on the vehicle body away from interference sources, while maintaining reliable communication through wireless transmission that doesn't require physical cable connections.
4Reliability
If continuous power supply is provided to anchors, then communication reliability is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic power supply to anchors through wireless communication protocols. Instead of continuous power delivery, the system uses periodic wake-up signals and data transmissions that consume power only when needed for communication operations. This periodic action maintains communication reliability while significantly reducing overall power consumption compared to continuous supply.

AI summary
A plurality of anchors are disposed on a vehicle, wireless communication is performed between the plurality of anchors, and the plurality of anchors include a first anchor and a second anchor. A 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.
