Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual donning is used in twisting and weaving factories, then operators can directly handle the winding packages, but the labor intensity is high and donning efficiency is low
Solution Approach 1:
The patent replaces the manual mechanical donning operation with an automated robotic system. The robot equipped with a specialized end effector automatically grasps, lifts, and positions winding packages onto bobbins, eliminating the need for operators to manually handle heavy packages. This substitution of manual mechanical operations with automated robotic mechanics directly resolves the contradiction by improving productivity while reducing labor intensity.
Solution Approach 2:
The patent introduces an intermediary robotic system that acts as a mediator between the winding packages and the bobbins. Instead of operators directly transferring packages, the robot serves as an intermediate agent that receives packages from conveyors, processes them, and places them on bobbins. This intermediary system enables automated high-speed donning while keeping operators out of the direct handling path, thus improving efficiency and reducing physical strain.
2Extent of automation
If robotic donning with AGV is implemented, then automation level increases, but control difficulty increases and the robot has weak ability to dodge operators causing disruptions
Solution Approach 1:
The patent implements feedback mechanisms through sensors and control systems that continuously monitor the robot's position, speed, and surrounding environment. The system receives real-time feedback about operator presence and adjusts robot operations accordingly, enabling smooth pausing or resumption of donning operations. This feedback loop makes the automated system responsive and easier to control during operator interactions, resolving the contradiction between high automation and control difficulty.
Solution Approach 2:
The patent employs dynamic control capabilities that allow the robot to adapt its behavior in real-time based on operational conditions. The system can dynamically pause, resume, or adjust its donning operations when operators need to intervene or pass through the workspace. This dynamic responsiveness enables the highly automated system to accommodate human operators smoothly, reducing control difficulty while maintaining high automation levels.
3Extent of automation
If existing automatic donning and doffing systems are used, then some automation is achieved, but manual donning is still required after doffing
Solution Approach 1:
The patent implements a continuous automated donning system that operates without interruption throughout the production cycle. The robotic system maintains continuous operation from package reception through donning, eliminating the breaks and manual interventions required by existing systems. The conveyor-fed automated system ensures uninterrupted donning operations, achieving both high automation level and sustained productivity without requiring manual donning after doffing events.
