Pin-Type Gripper Single Cylinder Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pin-type grippers are complex, large, and require intricate control systems due to their dual-cylinder design, leading to high production and operating costs and a higher likelihood of malfunctions.
Innovation Solution
A pin-type gripper with a single cylinder unit that controls two slide members with obliquely disposed pins, using a piston and 'V'-shaped links to transmit movement and adjust pin extraction range, simplifying the structure and control while reducing production and operating costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two cylinders are used to control the pin-type gripper, then the gripping function is achieved, but the structure becomes complex and the size becomes excessively large
Solution Approach 1:
The patent merges two separate cylinders into a single cylinder that controls both slide blocks simultaneously. The single cylinder receives air supply through multiple holes and uses a common piston to actuate both slide blocks, reducing structural complexity while maintaining the gripping function.
Solution Approach 2:
The single cylinder serves multiple functions by controlling both slide blocks through a common piston mechanism. The piston's movement simultaneously actuates the left and right slide blocks, making the single cylinder a multi-functional control element.
2Reliability
If two cylinders are used to control the pin-type gripper, then the gripping function is achieved, but the size of the gripper becomes excessively large
Solution Approach 1:
The patent combines two cylinder assemblies into one compact cylinder unit, significantly reducing the overall volume of the gripper. The single cylinder housing contains all necessary components including multiple air supply holes, a common piston, and linkages to both slide blocks, creating a more compact arrangement.
3Reliability
If two cylinders are used to control the pin-type gripper, then the gripping function is achieved, but special detailed design for controlling the two cylinders is required resulting in high possibility of malfunction or error
Solution Approach 1:
The patent merges the control functions into a single cylinder, eliminating the need for separate control mechanisms for two cylinders. This single control unit reduces the complexity of control systems and minimizes the risk of malfunction or operational errors.
Solution Approach 2:
The single cylinder serves as a universal control element that simultaneously actuates both slide blocks through the common piston and linkages, simplifying the control architecture and reducing operational complexity.
4Reliability
If two cylinders are used to control the pin-type gripper, then the gripping function is achieved, but a lot of time and effort are required to manufacture and operate the gripper
Solution Approach 1:
The patent consolidates multiple components into a single cylinder assembly, reducing the number of parts that need to be manufactured, assembled, and maintained. This merging of functions leads to shorter manufacturing cycles and easier operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The single-cylinder design simplifies the gripper's structure and control, reduces the risk of malfunctions, and allows for flexible handling of targets of varying materials and sizes, enhancing operational efficiency and cost-effectiveness.
Implementation Method 1
the piston may reciprocate by a means of the pressure of compression air which is supplied into the cylinder
Implementation Method 2
each of the links may include a 'v'-shaped member having a vertex as a rotating axis, wherein the first end and the second end of the link may respectively form opposite ends of the V-shaped member other than the vertex

AI summary
A pin-type gripper adapted for holding and transferring a target made of soft material. The pin-type gripper includes: a cylinder unit; a pair of slide blocks which are obliquely disposed at the left and right sides of the end of a piston rod and extend in a skirt shape; and links which transmit the piston motion to the slide blocks. A pin which pegs a target is installed on an end of each slide block. One cylinder unit controls two slide members at the same time. Thus, the pin-type gripper is superior in structure, control, and economic performance to a typical gripper that requires two cylinders and a complicated design.
