Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional vehicle simulation systems use a single model for each vehicle behavior influence factor, then the simulation system is simple to operate, but it cannot accurately simulate vehicle performance with different battery types and manufacturers
Solution Approach 1:
The patent segments the vehicle simulation into multiple independent behavior influence factors (acceleration, braking, steering, etc.), each with its own set of models. This allows the system to selectively apply different models for each factor based on the specific simulation needs, improving accuracy without overwhelming complexity.
Solution Approach 2:
The patent creates a universal simulation framework that can handle multiple battery types, manufacturers, and vehicle behaviors through a standardized interface. The system accommodates various battery characteristics (weight, capacity, output) within a single multi-functional platform, enabling accurate simulation across different scenarios.
2Adaptability or versatility
If the simulation system incorporates multiple battery models with different performance characteristics, then it can simulate various battery scenarios, but the system becomes more complex to operate
Solution Approach 1:
The patent implements a dynamic model selection mechanism that automatically chooses appropriate battery models based on the simulation parameters and requirements. The system can dynamically adjust which battery models are applied without requiring manual reconfiguration, maintaining ease of operation while supporting multiple battery types.
Solution Approach 2:
The patent uses parameter-based model selection where different battery models are chosen based on specific performance parameters (weight, capacity, output characteristics). This allows the system to handle diverse battery types through a unified parameter-driven approach, maintaining operational simplicity.
