Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If V2X communication is used to transmit data among network-connected vehicles, then mobility services and autonomous driving functionality are enabled, but security threats arise from false location reports and ghost vehicles
Solution Approach 1:
The patent introduces trusted agents as intermediary entities that mediate between vehicles and the MaaS system. These agents verify vehicle locations by detecting physical occlusions (when a vehicle passes between the agent and the target vehicle), thereby filtering out false location reports and ghost vehicles before information reaches the MaaS system.
Solution Approach 2:
The system implements feedback mechanisms where trusted agents continuously monitor and verify vehicle locations, providing corrective information back to the MaaS system when discrepancies are detected. This feedback loop enables real-time detection and correction of false location reports, maintaining reliability while preserving V2X communication versatility.
2Productivity
If MaaS system acts on incorrect vehicle location information, then vehicle dispatch is delayed or not fulfilled, but the system lacks effective detection mechanisms for false locations
Solution Approach 1:
The patent implements preliminary verification actions by deploying trusted agents to check vehicle locations before the MaaS system makes dispatch decisions. The agents proactively detect occlusions and verify actual vehicle positions in advance, preventing incorrect information from reaching the dispatch system and avoiding delays.
Solution Approach 2:
The system replaces reliance on vehicle-reported location data with a physical detection mechanism based on occlusion sensing. Trusted agents use sensors to detect when vehicles physically pass between the agent and the target vehicle, substituting mechanical/physical verification for electronic self-reporting, thereby achieving precise location verification.
3Measurement precision
If trusted agents detect abrupt signal attenuation to identify untrusted vehicles, then misbehavior detection accuracy is improved, but system complexity increases
Solution Approach 1:
The trusted agents use their own sensing capabilities to detect occlusions caused by untrusted vehicles. The system leverages the natural physical phenomenon of signal attenuation when objects block the path between transmitter and receiver, requiring no additional complex detection hardware beyond standard sensors already present in V2X infrastructure.
Solution Approach 2:
The patent converts the harmful effect of signal attenuation (caused by untrusted vehicles attempting to hide or deceive) into a beneficial detection mechanism. By monitoring for abrupt signal attenuation, the system transforms the occlusion that untrusted vehicles create into a detectable signature that reveals their presence and misbehavior.

AI summary
V2X trusted agents provide technical solutions for technical problems facing falsely reported locations of connected vehicles within V2X systems. These trusted agents (e.g., trusted members) may be used to detect an abrupt physical attenuation of a wireless signal and determine whether the attenuation was caused by signal occlusion caused by the presence of an untrusted vehicle or other untrusted object. When the untrusted vehicle is sending a message received by trusted agents, these temporary occlusions allow trusted members to collaboratively estimate the positions of untrusted vehicles in the shared network, and to detect misbehavior by associating the untrusted vehicle with reported positions. Trusted agents may also be used to pinpoint specific mobile targets. Information about one or more untrusted vehicles may be aggregated and distributed as a service.
