Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional kinematic methods are used for mechanical arm control, then the control system is simple and easy to implement, but the system cannot adapt to complex and dynamically changing environments
Solution Approach 1:
The patent replaces conventional kinematic control methods with a reinforcement learning-based control system. The TD3 algorithm learns optimal control policies through interaction with the environment, enabling the mechanical arm to adapt to complex and dynamically changing environments without requiring explicit programming of kinematic models for each scenario.
Solution Approach 2:
The patent employs a twin model architecture where one model is used for simulation and the other for actual control. This allows the system to learn from simulated environments and transfer the learned policies to the physical mechanical arm, improving adaptability while managing computational complexity through model-based learning.
2Adaptability or versatility
If conventional kinematic methods are used, then the control approach is straightforward, but the system lacks flexibility for multiple tasks
Solution Approach 1:
The patent implements dynamic adaptation through reinforcement learning, where the control policy is continuously updated based on task requirements and environmental feedback. This allows the mechanical arm to flexibly switch between multiple tasks by retraining or fine-tuning the TD3 model for different task scenarios, providing both adaptability and ease of operation.
3Extent of automation
If conventional control methods are used, then the system is simple to implement, but it cannot complete tasks autonomously in real-time complex environments
Solution Approach 1:
The patent enables autonomous task execution by implementing a reinforcement learning system that learns optimal control policies through self-interaction with the environment. The TD3 algorithm automatically adjusts control parameters based on task feedback, allowing the mechanical arm to complete tasks autonomously in real-time complex environments without human intervention.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors task performance and environmental conditions, using this information to update the reinforcement learning model. This feedback loop enables the system to learn from past experiences and improve its autonomous control capabilities over time, managing complexity through data-driven learning.
