Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single robotic hand is used for battery assembly, then the device complexity is reduced, but the adaptability and versatility for multiple assembly procedures deteriorates
Solution Approach 1:
The robotic hand is designed with multi-functionality to perform multiple assembly procedures including gripping, screwing, welding, and sealing operations. By integrating multiple end effectors with different functions into a single robotic hand system, the patent achieves universal applicability across various assembly tasks while maintaining relatively simple device architecture
Solution Approach 2:
The robotic hand employs dynamic switching between different end effectors based on assembly requirements. The system can dynamically select and switch between gripping mechanisms, screwing mechanisms, welding mechanisms, and sealing mechanisms to adapt to different assembly procedures, thereby achieving high versatility without permanent structural complexity
2Adaptability or versatility
If multiple end effectors are integrated into the robotic hand, then the adaptability for multiple assembly procedures improves, but the device complexity increases
Solution Approach 1:
The robotic hand system is segmented into multiple independent end effectors (gripping mechanism, screwing mechanism, welding mechanism, sealing mechanism) that can be selectively activated. Each end effector is designed as a modular unit with specific functionality, allowing the system to achieve high adaptability while managing complexity through functional segmentation and selective deployment
3Ease of manufacture
If a single robotic hand performs all assembly actions, then the production cost is reduced, but the assembly precision and quality for different procedures deteriorates
Solution Approach 1:
Different end effectors are designed with specialized structures optimized for their specific functions. The gripping mechanism has finger structures adapted for different battery components, the screwing mechanism has precision positioning for screw holes, the welding mechanism has focused energy delivery for precise welding, and the sealing mechanism has conformal contact surfaces. This local optimization of quality for each function ensures high assembly precision while maintaining cost-effectiveness through targeted design
