Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption mechanisms and secure protocols are implemented for automobile data transmission, then data security and integrity are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent introduces a network entity (such as a base station or server) as an intermediary that performs encryption and security functions. Instead of requiring complex encryption mechanisms within the automobile device itself, the network entity handles these security operations, thereby reducing the complexity burden on the vehicle's communication module while maintaining data security.
Solution Approach 2:
The system employs authentication mechanisms where the automobile device presents identification information to the network entity, which automatically verifies credentials and establishes secure connections. This self-service authentication approach simplifies the device requirements while ensuring security through automated network-side verification.
2Reliability
If dynamic modulation and coding schemes are used to adapt to changing radio conditions, then transmission reliability is improved, but device complexity and control requirements increase
Solution Approach 1:
The patent implements feedback mechanisms where the network entity receives information about radio conditions from the automobile device and dynamically adjusts modulation and coding schemes accordingly. This feedback-based adaptive modulation allows the system to optimize transmission reliability while centralizing the control logic in the network entity, reducing the complexity burden on the vehicle.
Solution Approach 2:
The system dynamically selects modulation and coding schemes based on real-time radio conditions rather than using fixed configurations. This dynamic adaptation enables the system to respond to changing environmental conditions, improving transmission reliability while the network entity manages the complexity of multiple modulation modes.
3Adaptability or versatility
If multiple sensors and communication protocols are integrated for comprehensive data collection, then data completeness and system functionality are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs a universal communication protocol framework that can handle multiple types of data from various sensors (e.g., GPS, vehicle sensors, environmental sensors) through a standardized interface. This multi-functional communication layer simplifies the integration of diverse sensors by providing a unified approach to data collection and transmission, reducing the complexity of managing multiple separate systems.
