Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conveyor is used to transfer radical units, then the transfer process can be automated, but the facility configuration becomes complicated and individual position and speed control of objects is not achieved
Solution Approach 1:
The conveyor system is segmented into multiple independent suction cups that can be individually controlled. Each suction cup acts as an independent module capable of separate position and speed control, allowing precise manipulation of individual radical units while maintaining overall system automation.
Solution Approach 2:
The suction cups are designed with dynamic control capabilities, where the position and speed of each suction cup can be independently adjusted during operation. This dynamic control enables precise placement of radical units at different locations and speeds, resolving the contradiction between automation and control precision.
2Productivity
If a conveyor is used for transferring radical units, then continuous transfer is possible, but stable adsorption of objects cannot be ensured
Solution Approach 1:
Different regions of the conveyor system have different adsorption characteristics. The suction cups are designed with varying suction forces and contact areas depending on their specific function and position, allowing optimized adsorption for each local requirement while maintaining continuous operation.
Solution Approach 2:
The suction cups establish preliminary contact with the radical units before full transfer begins. This preliminary action ensures stable adsorption is achieved before the transfer process commences, preventing instability during the transition while maintaining continuous productivity.
3Manufacturing precision
If the loading part moves toward the object using elastic force, then the adsorption plate can make close contact with the object, but additional components are required
Solution Approach 1:
The elastic member provides self-service by automatically pushing the loading part toward the object using stored elastic force. This eliminates the need for separate actuators or motors for each loading action, achieving precise contact while minimizing additional components through the self-propelled mechanism.
