Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single robotic hand is used for battery assembly, then device complexity is reduced, but adaptability and versatility deteriorate because it cannot complete assembly actions for multiple procedures
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 various end effectors (gripper, screw driver, welding tool, sealing tool) that can be quickly exchanged, a single robotic hand system achieves the adaptability of multiple specialized robotic hands while maintaining manageable device complexity through standardized interfaces and control architecture.
2Adaptability or versatility
If multiple end effectors are introduced to perform multiple assembly procedures, then versatility improves, but device complexity increases
Solution Approach 1:
The system implements dynamic adaptability through a quick-change mechanism that allows the robotic hand to exchange end effectors during operation. This dynamic configuration enables the system to adapt to different assembly procedures (gripping, screwing, welding, sealing) by selecting appropriate end effectors, achieving high versatility while managing complexity through on-demand tool replacement rather than permanent multi-tool integration.
Solution Approach 2:
The robotic hand system is segmented into modular components: the main robotic hand unit and interchangeable end effectors (gripper, screw driver, welding tool, sealing tool). This segmentation allows each component to be optimized independently and facilitates quick exchange of tools based on assembly requirements, improving versatility while keeping the overall system complexity manageable through standardized connection interfaces.
3Manufacturing precision
If a single robotic hand performs all assembly procedures, then device complexity is minimized, but manufacturing precision deteriorates due to inability to meet high precision requirements for different procedures
Solution Approach 1:
The robotic hand achieves high manufacturing precision across different assembly procedures by integrating multiple specialized end effectors (gripper for precise positioning, screw driver for torque control, welding tool for joint precision, sealing tool for gasket installation) while maintaining a unified control system. This multi-functional design ensures each procedure receives the appropriate tool for high-precision execution without requiring separate robotic systems.
4Manufacturing precision
If multiple specialized robotic hands are used for different assembly procedures, then manufacturing precision improves, but device complexity and production costs increase
Solution Approach 1:
The system merges multiple specialized robotic hands into a single unified robotic hand platform that can perform gripping, screwing, welding, and sealing operations. By combining these functions into one system with a quick-change mechanism for end effectors, the patent achieves the manufacturing precision of specialized tools while reducing device complexity and production costs compared to using multiple separate robotic hands.
Solution Approach 2:
A single robotic hand is designed to perform multiple assembly procedures with high precision by integrating various end effectors (gripper, screw driver, welding tool, sealing tool). This universal design eliminates the need for multiple specialized robotic hands, reducing overall system complexity and cost while maintaining high manufacturing precision through procedure-specific tool selection.
