Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are fixed using screw bolts, then the connection strength and reliability are improved, but the assembly complexity and time increase
Solution Approach 1:
The actuator is divided into modular components (motor assembly, lead screw assembly, nut assembly, end cover assembly) that can be independently manufactured and assembled. Each module is designed with standardized interfaces using pin-based fixation instead of traditional screw bolt connections, enabling rapid assembly while maintaining structural integrity and reliability.
2Stability of the object's composition
If screw bolts are used to fix components, then the structural stability is improved, but the labor cost and assembly time increase
Solution Approach 1:
The traditional screw bolt fixation method is extracted and replaced with a pin-based fixation system. Pins are inserted through aligned holes in modular components to achieve rapid connection, significantly reducing assembly time and labor costs while maintaining sufficient structural stability for the actuator application.
3Productivity
If modular design with pins is used, then the assembly speed and labor efficiency are improved, but the fixation strength may be reduced
Solution Approach 1:
Multiple pins are used in combination with the modular component design to distribute and aggregate the fixation strength across multiple connection points. This merging of multiple weak pin connections creates an overall strong and stable assembly, achieving both rapid assembly and sufficient fixation strength.
