Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate wireless communication system is added to the automotive radar system, then communication capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the wireless communication transceiver with the radar transceiver into a single integrated unit. The communication transceiver shares the same antenna, signal processing resources, and hardware components with the radar system, eliminating the need for separate communication hardware and reducing overall system complexity while maintaining both radar detection and wireless communication capabilities
Solution Approach 2:
The radar transceiver is designed to perform multiple functions: it operates as a radar system for detection and ranging, and simultaneously functions as a wireless communication transceiver for V2X communication. The same hardware infrastructure supports both radar signaling and communication signaling, making the system multi-functional and adaptable to different operational modes
2Productivity
If the same frequency range is used for both detection/ranging and communication, then spectrum efficiency is improved, but signal interference increases
Solution Approach 1:
The system employs time-division multiplexing where the transceiver alternates between radar modes (detection and ranging) and communication modes (V2X signaling). By periodically switching between these functions in the same frequency band, the system achieves spectrum efficiency while preventing continuous interference through temporal separation of operations
Solution Approach 2:
The system dynamically adjusts its operational mode based on real-time requirements, switching between radar-only, communication-only, or combined modes. This dynamic adaptability allows the system to optimize spectrum usage while managing interference levels according to current operational needs, traffic conditions, and communication priorities
3Object-generated harmful factors
If separate antennas are used for communication and radar, then signal isolation is improved, but device complexity increases
Solution Approach 1:
The patent utilizes a single shared antenna for both radar transmission/reception and wireless communication transmission/reception. The antenna is designed to handle both signal types, and the system employs signal processing techniques to separate and isolate radar signals from communication signals, eliminating the need for multiple separate antennas while maintaining adequate signal isolation
Solution Approach 2:
The system employs signal processing circuits and filters as intermediaries between the shared antenna and the transceiver components. These intermediary elements selectively process and route signals, isolating radar signals from communication signals in the shared antenna system, thereby achieving signal separation without requiring separate physical antennas
