Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If simulation results are only informed without displaying learning status, then the system is simple, but the information completeness about operational efficiency learning is insufficient
Solution Approach 1:
The information display is segmented into multiple components: simulation results display, learning status display, and learning effect display. This segmentation allows comprehensive information presentation while maintaining clear organization and manageable system complexity.
Solution Approach 2:
The display control unit acts as an intermediary that processes and coordinates information from the simulation unit and learning unit, then presents it through the information display device. This intermediary component manages the complexity of presenting comprehensive information without overwhelming the system.
2Loss of information
If learning status and simulation results are displayed, then the information completeness is improved, but the device complexity increases
Solution Approach 1:
The information display device is designed with multi-functionality to display various types of information including simulation results, learning status, and learning effects. This universal display capability reduces the need for separate dedicated display devices for each information type, thereby managing complexity while improving information completeness.
Solution Approach 2:
The system implements feedback mechanisms where the display control unit continuously updates the information display device with current learning status and simulation results. This feedback loop provides comprehensive information about operational efficiency learning while using a centralized control approach to manage system complexity.
3Measurement precision
If the system only informs simulation results, then the device complexity is low, but the ability to evaluate learning effect on operational efficiency is insufficient
Solution Approach 1:
The patent replaces physical measurement instruments with information processing and display mechanisms. The simulation unit virtually runs the car based on learned policies and evaluates operational efficiency through computational simulation rather than physical measurement, reducing hardware complexity while improving evaluation precision.
Solution Approach 2:
The simulation unit serves as an intermediary between the learning unit and the evaluation process. It virtually executes the learned car running policies and measures operational efficiency, providing precise evaluation without requiring complex physical testing infrastructure.
