Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple vehicle communication networks with different protocols are used to support diverse vehicle components, then the system can handle more fault conditions and improve reliability, but the device complexity increases due to protocol conversion and message routing requirements
Solution Approach 1:
The patent introduces a gateway as an intermediary device that mediates communication between vehicle components on different communication networks. The gateway receives health codes from components via their native protocols, converts them to a standardized format, and routes them appropriately. This intermediary approach enables multi-protocol support without requiring each component to handle multiple protocols directly, thus improving reliability while managing complexity through centralized protocol conversion.
Solution Approach 2:
The patent segments the communication system into distinct layers: component level (health code generation), network level (protocol-specific transmission), and gateway level (standardization and routing). Each layer handles specific protocols or formats independently, allowing the system to support diverse communication protocols without creating monolithic complexity. The segmentation enables independent development and maintenance of each communication layer.
2Reliability
If health codes are broadcasted on multiple communication networks simultaneously, then fault information can be detected more reliably through redundancy, but the loss of information increases due to potential duplicate processing and protocol conversion errors
Solution Approach 1:
The gateway implements feedback mechanisms to track health code transmissions across multiple networks. It monitors which networks have successfully received and processed health codes, and can request retransmission if information is lost or corrupted. This feedback loop ensures reliable fault information detection while maintaining information consistency by verifying successful delivery before considering the transmission complete.
Solution Approach 2:
The patent creates standardized copies of health codes for transmission across different communication networks. Instead of directly converting between protocols (which may lose information), the gateway creates a standardized intermediate representation of the health code that preserves all essential information, then generates protocol-specific copies for each target network. This copying approach maintains information consistency while enabling multi-network broadcast.
3Reliability
If the system processes multiple fault conditions simultaneously from different components, then comprehensive vehicle safety can be ensured, but the difficulty of detecting and measuring increases due to prioritization and conflict resolution requirements
Solution Approach 1:
The patent assigns different priority levels and processing qualities to different fault conditions based on their local characteristics and impact on vehicle safety. Critical faults (e.g., braking system failures) receive immediate high-priority processing, while less critical faults (e.g., non-safety sensor failures) are processed with lower priority. This local quality differentiation enables comprehensive safety monitoring while simplifying detection and measurement by applying context-appropriate processing rules to each fault type.
Solution Approach 2:
The system performs preliminary classification and prioritization of fault conditions as they are received, before full processing occurs. The gateway pre-sorts incoming health codes by priority level and routes them to appropriate processing queues. This preliminary action reduces the complexity of simultaneous fault processing by organizing work in advance, allowing the system to handle multiple fault conditions efficiently based on their predetermined priority levels.

AI summary
Described herein are systems, methods, and non-transitory computer-readable media for self-detection of fault conditions experienced by vehicle components, generation of device health codes indicative of the fault conditions, and broadcasting of the device health codes over mixed vehicle communication networks. The device health codes can be parsed to identify fault information, and the fault information can be assessed along with current vehicle operational data to determine a recommended vehicle response measure to one or more fault conditions experienced by one or more vehicle components.
