Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual driver inputs and basic control systems are used, then device complexity is reduced, but electric motor performance and adaptability deteriorate
Solution Approach 1:
The control system continuously receives feedback from sensors monitoring motor operating conditions, battery state, and environmental factors. This feedback loop enables the machine learning model to dynamically adjust motor control parameters, achieving adaptive performance while maintaining manageable system complexity through integrated sensor-controller architecture.
Solution Approach 2:
The machine learning model autonomously determines optimal motor control strategies without requiring manual driver intervention. The system self-adjusts power delivery, torque, and operational modes based on real-time data, enabling the vehicle to serve itself in optimizing performance while reducing the complexity of manual control interfaces.
2Productivity
If aggressive power delivery strategies are used, then productivity is improved, but loss of energy and wear on components increase
Solution Approach 1:
The system dynamically changes operational parameters including power delivery rate, torque output, and motor speed based on real-time conditions. The machine learning model optimizes these parameters to achieve maximum productivity while minimizing energy loss, adjusting the balance between performance and efficiency according to battery state, driving conditions, and environmental factors.
Solution Approach 2:
The control system transitions from static power delivery strategies to dynamic adjustment mechanisms. Power delivery characteristics continuously adapt based on real-time sensor data, enabling the system to optimize the trade-off between productivity and energy consumption by modulating motor output in response to changing operational conditions.
3Adaptability or versatility
If real-time sensor data processing is implemented, then adaptability is improved, but use of energy and device complexity increase
Solution Approach 1:
The system processes sensor data at varying levels of detail based on operational context. Rather than continuously processing all sensor inputs at maximum computational intensity, the machine learning model selectively processes data at appropriate granularity, reducing energy consumption while maintaining necessary adaptability for real-time motor control adjustments.
