Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of lifting a bobbin using a hoist and string is performed, then the lifting function is achieved, but there is a risk of fall accident and dangerous work conditions
Solution Approach 1:
The patent replaces the manual mechanical lifting system (hoist and string) with an automated robotic system featuring a robot arm equipped with sensors and control units. The robot automatically detects the bobbin position using sensors, calculates the lifting trajectory, and executes the lifting operation without human intervention, thereby eliminating fall accidents and dangerous manual operations while maintaining lifting functionality.
2Reliability
If two or more workers perform the lifting work, then the safety risk is reduced, but the complexity of operation increases
Solution Approach 1:
The patent implements a self-service automated system where the robot arm autonomously performs the entire lifting operation. The system includes automatic bobbin detection through sensors, automated trajectory calculation, and self-executed lifting without requiring multiple workers or complex coordination, thereby maintaining safety while reducing operational complexity to a single automated unit.
3Productivity
If automated lifting system is implemented, then worker reduction and safety enhancement are achieved, but the device complexity increases
Solution Approach 1:
The patent employs a multi-functional robotic system that integrates multiple capabilities into a single device: bobbin detection through various sensors, trajectory calculation through control algorithms, lifting execution through the robot arm, and adaptive adjustment based on real-time feedback. This universal system replaces multiple workers and performs all lifting operations autonomously, achieving worker reduction and safety enhancement while consolidating complexity into one integrated automated unit.
