Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LTE-based protocols are used for device discovery in V2X communication, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the V2X communication system into distinct functional components: discovery messages for device identification, resource allocation messages for resource management, and separate protocol layers for handling different communication aspects. This segmentation allows complex LTE-based protocols to be implemented in a structured manner, improving reliability while managing device complexity through modular design.
Solution Approach 2:
The patent implements universal resource allocation mechanisms that can handle multiple V2X scenarios (vehicle-to-vehicle, vehicle-to-infrastructure, vehicle-to-pedestrian) using the same LTE-based protocol framework. This multi-functionality approach improves communication reliability across diverse applications while avoiding the need for separate complex protocols for each scenario.
2Productivity
If enhanced modulation schemes and dynamic carrier aggregation are implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic carrier aggregation where carriers are aggregated and configured based on real-time communication needs and channel conditions. This dynamic approach enables the system to achieve high productivity when needed while reducing complexity by activating only necessary carriers, rather than maintaining fixed complex configurations.
Solution Approach 2:
The patent employs enhanced modulation schemes that can adapt modulation parameters (such as QPSK, 16-QAM, 64-QAM) based on channel quality and communication requirements. This parameter adaptation allows the system to achieve high communication efficiency when conditions permit while reducing complexity by using simpler modulation when channel conditions are poor.
3Adaptability or versatility
If visibility configurations are used to optimize communication, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements visibility configurations that allow different levels of device visibility and accessibility in different communication contexts. For example, certain devices may be fully visible to all other devices in a platoon, while others may have restricted visibility based on their role or security requirements. This local quality approach enables adaptability for different V2X scenarios while managing complexity through context-specific configurations rather than universal complexity.
