Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual design and editing methods are used to create simulation scenes, then the quality and precision of scene design can be maintained, but the productivity and time consumption are severely limited
Solution Approach 1:
The system enables automatic generation of simulation scenes by having the computer execute algorithms that self-organize traffic elements, vehicles, and road structures based on map data, eliminating the need for manual design while maintaining scene quality through automated parameter optimization
Solution Approach 2:
The patent transforms the scene generation process by changing parameters from manual control to automated control through algorithms that adjust traffic element positions, vehicle trajectories, and scene configurations based on input map data and predefined rules, thereby improving both efficiency and consistency
2Ease of manufacture
If manual design methods are used for simulation scenes, then detailed control over scene elements is possible, but the quantity and diversity of scenes that can be created are limited
Solution Approach 1:
The patent segments the scene generation process into independent modular components including traffic element generation modules, vehicle trajectory generation modules, and scene assembly modules, allowing parallel processing and rapid generation of multiple diverse scenes through systematic combination of standardized elements
Solution Approach 2:
The system creates universal scene generation capabilities that can handle multiple types of intersections and traffic scenarios through a single automated framework, enabling the same system to generate diverse scenes ranging from simple crossroads to complex multi-lane intersections with various vehicle types and traffic patterns
3Productivity
If automated methods are introduced to increase scene generation efficiency, then productivity improves, but the complexity of the generation system increases
Solution Approach 1:
The patent introduces an intermediary computer system that acts as a mediator between the input map data and the output simulation scenes, executing predefined algorithms and rules to automatically generate scene elements, thereby simplifying the overall process while maintaining high productivity through centralized automated control
