Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a vertical type vacuum gripper device is used, then installation space is reduced and compactness is improved, but the design for generating and breaking vacuum becomes complex and operation becomes cumbersome
Solution Approach 1:
The device is divided into separate functional modules: a cylindrical body housing the ejector, a detachable pad assembly, and separate valve components. This segmentation allows each component to be optimized independently while maintaining compact overall dimensions, resolving the contradiction between compactness and operational simplicity
Solution Approach 2:
The breaking valve is extracted from the main body and positioned externally on the cylindrical surface, allowing it to be easily accessible for operation while maintaining a compact internal structure. This extraction simplifies the internal vacuum generation design while preserving space efficiency
2Volume of moving object
If a vertical type vacuum gripper device is used, then installation space is reduced, but it becomes very difficult to install and operate air valves inside the device
Solution Approach 1:
The breaking valve is extracted from the internal structure and positioned on the external cylindrical surface of the body, making it easily accessible for installation and operation while maintaining compact dimensions
Solution Approach 2:
A connector piece is introduced as an intermediary component that facilitates valve installation and operation. The connector provides external access points for valves while maintaining the compact cylindrical structure, serving as a mediator between the compact design requirement and ease of valve operation
3Ease of manufacture
If the number of ejectors is fixed, then manufacturing is simplified, but it becomes difficult to respond to diverse grip characteristics required in actual fields
Solution Approach 1:
The ejector configuration is made dynamic and adjustable rather than fixed. The device allows for varying the number and arrangement of ejectors based on specific application requirements, enabling adaptation to diverse grip characteristics while maintaining relatively simple manufacturing through modular components
Solution Approach 2:
The cylindrical body design with standardized mounting interfaces creates a universal platform that can accommodate different numbers and types of ejectors. This multi-functional design allows a single base structure to serve multiple gripping applications with varying requirements

Function Achieved in This Case
Simplifies manufacturing and operation, facilitates easy valve placement, and enables adaptable grip characteristics by varying ejector numbers, enhancing device flexibility and efficiency.
Implementation Method 1
when compressed air passes through the ejector at a high speed, air inside the pad is induced into the ejector and then discharged to the outside together with the compressed air, and in this process, a vacuum and negative pressure are generated inside the pad

AI summary
The present invention relates to a vertical type vacuum gripper device. The vertical type vacuum gripper device includes a cylindrical body provided with a built-in air ejector mounted in a longitudinal direction, a connector coupled to a lower end of the body, and an adsorption pad connected to the connector. Particularly, the body includes an upper cover in which a plurality of air supply ports are provided, a breaking tube which is provided as a tube parallel to the ejector on a lower bottom surface and in which the inside of the tube communicates with an inner space of the adsorption pad, an air outlet provided in a lower portion of a side surface, and a passage provided in the bottom surface to allow the upper body and the inner space of the lower adsorption pad to communicate with each other. Thus, a vacuum passing extending from a first supply port → the ejector → the outlet and a breaking passage extending from a second supply port → the breaking tube → the inner space of the pad are defined.
