Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If developers test synthetic sensors on real vehicles with access to live data, then testing accuracy and reliability are improved, but accessibility and ease of operation deteriorate due to limited access to real vehicle hardware
Solution Approach 1:
The patent creates virtual copies of real vehicle environments, hardware configurations, and sensor data through simulated test nodes. These virtual representations allow developers to test synthetic sensors with the same reliability as real vehicles would provide, while eliminating the accessibility barriers of physical hardware requirements.
Solution Approach 2:
The patent introduces an intermediary testing system that sits between the developer and the actual vehicle hardware. This intermediary provides a configuration catalog and automated test node generation that mediates access to vehicle testing environments, making them accessible without direct hardware access.
2Adaptability or versatility
If developers manually configure test environments for each vehicle configuration, then adaptability to different vehicle configurations is improved, but time consumption and complexity increase
Solution Approach 1:
The patent pre-configures multiple test nodes in advance, each representing different vehicle configurations, hardware setups, and sensor arrangements. These pre-configured test nodes are stored in a configuration catalog, allowing developers to immediately deploy appropriate test environments without manual configuration time.
Solution Approach 2:
The patent creates a universal configuration catalog that contains test node configurations applicable across multiple vehicle types and configurations. A single test node can be adapted to represent different vehicle configurations through parameter selection, eliminating the need to manually configure each specific vehicle setup.
3Reliability
If comprehensive testing across multiple vehicle configurations is performed, then validation accuracy and reliability are improved, but resource requirements and system complexity increase
Solution Approach 1:
The patent segments the comprehensive testing task into multiple independent, pre-configured test nodes, each representing a specific vehicle configuration. This segmentation allows the complex validation task to be divided into manageable, reusable components that can be selected and executed based on testing needs without overwhelming system complexity.
