Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce the size of air cylinders used in manufacturing and transport devices while maintaining necessary thrust, as size reduction leads to a decrease in cross-sectional area and thrust deterioration.
Innovation Solution
The design incorporates a cylinder, piston rod, piston, and gas controller, with multiple pistons and partition walls to manage compressed gas supply and suction, using a gas discharge device to create vacuum pressure for enhanced thrust, allowing for a smaller air cylinder size without compromising performance.

Engineering Contradiction Analysis
1Volume of moving object
If the size of air cylinder is reduced, then device size can be reduced, but thrust deteriorates due to decrease in cross-sectional area
Solution Approach 1:
The cylinder interior is divided into multiple independent spaces by partition walls, with pistons operating in each space. This segmentation allows multiple thrust-generating surfaces to work simultaneously, increasing total thrust while maintaining a compact overall cylinder volume.
Solution Approach 2:
The invention transitions from a single-piston linear arrangement to a multi-piston multi-space configuration, effectively adding dimensional complexity to the thrust generation mechanism. Multiple pistons operate in parallel across different spaces, multiplying the thrust output without proportionally increasing the cylinder's external dimensions.
2Force
If multiple pistons and partition walls are added to increase thrust, then device complexity increases
Solution Approach 1:
Multiple pistons are integrated onto a single piston rod, and multiple partition walls are combined within one cylinder body. This merging approach allows the system to achieve multiplied thrust capability while minimizing the number of separate components and assembly steps, thereby controlling complexity.
Solution Approach 2:
The piston rod serves multiple functions by supporting several pistons simultaneously, and the partition walls serve dual purposes of space division and thrust multiplication. This multi-functionality reduces the overall component count and simplifies the structural design despite the enhanced thrust capability.

Function Achieved in This Case
This configuration increases thrust and enables the reduction of air cylinder size, maintaining or exceeding the thrust of larger cylinders, thus allowing for more compact devices.
Implementation Method 1
The gas controller supplies gas into one of a space, which is a space in the cylinder directed on the side of the piston rod with respect to the piston, and a space, which is a space in the cylinder opposite to the space with respect to the piston, and sucks gas from the interior of the other of the spaces

AI summary
An air cylinder includes a cylinder, a piston rod, a piston, and a controller. The piston rod has one end disposed in the cylinder and the other end protruding from the cylinder. The piston is provided at the one end of the piston rod and moves the piston rod by moving in the cylinder. The controller supplies gas into one of a space, which is a space in the cylinder directed on the piston rod side with respect to the piston, and a space, which is a space in the cylinder opposite to the space with respect to the piston, and sucks gas from an interior of the other of the spaces.
