Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a platform is designed according to formats of specific sensor and driving device, then the platform can be applied to that specific vehicle, but it cannot be applied to vehicles with different sensors due to diversified data formats
Solution Approach 1:
The patent introduces a data converting unit as an intermediary component between diverse sensors/driving devices and the driving control algorithm platform. This unit receives data in various formats from different manufacturers and models, converts it to a standardized internal format, and enables the platform to process data uniformly without requiring separate platform designs for each device type.
Solution Approach 2:
The driving control algorithm platform is designed with universal functionality to handle multiple types of sensors and driving devices through a unified data processing architecture. The platform can process data from LIDAR, cameras, GPS, and various driving devices regardless of manufacturer or model, achieving multi-functionality without increasing design complexity.
2Reliability
If different platforms are designed according to specifications of sensors and driving devices, then each platform can support specific devices, but significant difficulty occurs in implementing the platforms and replacement time and cost increase
Solution Approach 1:
The data converting unit serves as a mediator that decouples the dependency between specific device specifications and the control platform. When devices need replacement or upgrading, only the data converting unit needs to be reconfigured to recognize new device formats, while the core driving control algorithm platform remains unchanged, significantly reducing replacement time and cost.
3Productivity
If a platform is designed for specific sensor and driving device formats, then the driving control algorithm can work for that configuration, but the algorithm cannot be reused for vehicles with different hardware and software protocols
Solution Approach 1:
The data converting unit and driving control message generating unit act as intermediaries that standardize data formats before they reach the driving control algorithm. This allows the same driving control algorithm to be reused across different vehicle configurations, as all incoming data is normalized to a common format that the algorithm can process universally.
Solution Approach 2:
The system separates the format conversion functionality from the driving control algorithm itself. The data converting unit handles format diversity, while the driving control algorithm focuses on decision-making. This segmentation allows the algorithm to remain simple and reusable while the conversion layer handles the complexity of multiple formats.
