Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base station communication is used for M2M communication, then communication infrastructure is established, but latency time increases and transmission capacity is limited
Solution Approach 1:
The patent introduces a V2X communication system as an intermediary that enables direct peer-to-peer communication between vehicles and infrastructure without relying on base stations. This mediator architecture allows vehicles to exchange position and movement information directly, eliminating the latency introduced by base station relay while maintaining communication reliability through dedicated short-range communication protocols
2Measurement precision
If object position estimation is performed using existing technologies, then position information is obtained, but measurement precision is insufficient for accurate direction recognition
Solution Approach 1:
The patent combines multiple positioning technologies (GPS, IMU, UWB) into a unified position estimation system that achieves high measurement precision. By merging these complementary technologies, the system overcomes the limitations of individual methods and achieves accurate position and direction recognition without requiring overly complex standalone systems
Solution Approach 2:
The system implements real-time feedback mechanisms where position estimation results are continuously updated and verified through mutual information exchange between objects. This feedback loop enables the system to refine position estimates and improve measurement precision dynamically while maintaining manageable system complexity through iterative optimization
3Reliability
If real-time position and movement path information is exchanged between objects, then accident risk is reduced, but communication transmission capacity requirements increase
Solution Approach 1:
The patent extracts and transmits only the essential elements needed for safety - position coordinates, movement direction, and speed information - rather than transmitting complete object state data. This selective extraction of critical information reduces the data transmission volume while maintaining sufficient information for real-time collision avoidance and safety monitoring
