Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual torque adjustment is used to control paddle movement, then the system can be operated with simple mechanics, but the operation speed and resistance vary due to mechanical wear and age
Solution Approach 1:
The system performs self-learning by automatically measuring actual paddle movement characteristics and using machine learning models to adapt control parameters, eliminating the need for manual torque adjustments and compensating for mechanical wear and age variations
Solution Approach 2:
The system implements feedback loops where sensor data from actual paddle movements is captured, compared with desired movements, and used to continuously train and improve the machine learning model, ensuring consistent and reliable operation despite mechanical degradation
2Adaptability or versatility
If fixed control parameters are used for gate operation, then the system is simple to program, but it cannot adapt to different user behaviors and interactions
Solution Approach 1:
The system automatically adapts to different user behaviors by capturing sensor data, formulating training data from actual versus desired movements, and self-training the machine learning model without requiring manual reconfiguration or complex programming for each scenario
Solution Approach 2:
The machine learning model dynamically adjusts control parameters based on learned patterns from sensor data, allowing the system to adapt to varying user behaviors and interactions while maintaining a relatively simple underlying control structure
3Productivity
If the paddles close quickly to prevent fare evasion, then fare compliance is improved, but the risk of injury to transit users increases
Solution Approach 1:
The system uses machine learning to predict safe closing speeds and timing based on learned patterns from sensor data about user interactions, allowing the paddles to close quickly when safe while preventing injuries by anticipating potentially harmful situations before they occur
Solution Approach 2:
The control system dynamically adjusts paddle movement parameters based on real-time sensor data and learned patterns, varying the closing speed and timing to maximize throughput while minimizing injury risk根据不同用户交互模式动态优化
