Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If CAN signals are transmitted without driving video, then signal transmission is simple, but user understanding of vehicle parameter signals in different scenarios is not intuitive
Solution Approach 1:
The patent combines CAN signal transmission with driving video output into a unified simulation device. The device simultaneously outputs vehicle body parameter signals and external motion images, merging previously separate functions into one integrated system that provides both data and visual context.
Solution Approach 2:
The simulation device is designed to handle multiple vehicle models from different brands with unified signal specifications. It can process and output signals for various vehicle types while maintaining consistent data formats, enabling the device to serve multiple purposes across different automotive applications.
2Manufacturing precision
If vehicle body parameter signals are not synchronized with driving video, then device operation is simple, but accuracy of design for vehicle system is reduced
Solution Approach 1:
The device establishes a synchronous relationship between CAN signal output and driving video playback. By using the video timestamp as a reference, the system ensures that vehicle parameter signals are accurately timed and correlated with corresponding driving scenarios, providing feedback alignment between data and visual context.
Solution Approach 2:
The system pre-processes and stores driving video with embedded timestamp information before signal synchronization. This preliminary preparation of video data with time references enables accurate subsequent synchronization of vehicle parameter signals without requiring complex real-time processing during operation.
3Ease of manufacture
If output signals and specifications of various vehicle models are not unified, then each model can be obtained individually, but design costs increase significantly
Solution Approach 1:
The simulation device implements unified signal specifications that work across multiple vehicle brands and models. By standardizing output formats and signal definitions, the device can generate compatible signals for different manufacturers without requiring separate acquisition processes, enabling universal application in vehicle system design.
Solution Approach 2:
The device adjusts signal parameters according to different vehicle models while maintaining unified output specifications. It transforms model-specific signal variations into standardized formats through parameter mapping and conversion, allowing the same device to serve multiple vehicle types with consistent data structures.
