Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simulated sensor data is processed through standard graphics interfaces (HDMI, DVI, DisplayPort), then the data can be transmitted to the test environment, but processing latency and delay increase
Solution Approach 1:
A dedicated processing device with bus interface and output interface is introduced as an intermediary component between the host system and test environment. This device includes a processing circuitry that directly accesses simulated sensor data through the bus interface and outputs processed data through the output interface, eliminating the need to route data through standard graphics interfaces and thereby reducing processing latency while maintaining simulation accuracy.
2Adaptability or versatility
If simulated sensor data is converted through multiple interfaces (graphics interface to sensor interface), then compatibility with test environment is achieved, but processing complexity increases
Solution Approach 1:
The processing device merges multiple functions into a single integrated component: the bus interface for data access, the processing circuitry for data conversion and processing, and the output interface for data transmission. This consolidation eliminates the need for separate conversion steps between graphics interfaces and sensor interfaces, reducing processing complexity while maintaining compatibility with the test environment through direct interface support.
3Productivity
If direct bus access is implemented for simulated sensor data, then processing speed increases, but hardware integration complexity increases
Solution Approach 1:
The processing device is designed with universal functionality to interface with standard bus architectures (PCIe, PCI, USB, SATA, SAS, NVLink) and provide standardized output interfaces (MIPI, FPD-Link, GMSL, LVDS). This multi-functionality allows the device to achieve high processing speeds through direct bus access while maintaining ease of integration through support for industry-standard interfaces, reducing hardware integration complexity.
