Fluid Pressure Cylinder Damper Retention via Segmented Elastic Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid pressure cylinders face issues with damper detachment and assembly complexity due to the use of elastic materials and gaskets, which compromise the sealing and ease of assembly.
Innovation Solution
A fluid pressure cylinder design featuring a cylinder body with a piston and cover members, where dampers are mounted with retaining members that engage with the cylinder body's side surfaces, preventing detachment and simplifying assembly by using a combination of elastic materials and metallic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dampers are formed from elastic materials and disposed on ends of head cover and rod cover, then shock absorption ability is improved, but the dampers may become detached and fall off from the covers
Solution Approach 1:
The damper is divided into a main body portion and a retaining member portion. The retaining member extends perpendicularly from the main body and is engaged with the side surface of the cover member, creating a segmented structure that prevents detachment while maintaining shock absorption capability.
Solution Approach 2:
The retaining member extends in a direction perpendicular to the main body portion of the damper, adding a dimensional element that engages with the side surface of the cover member. This perpendicular extension prevents the damper from falling off while allowing it to maintain its shock absorption function.
2Stability of the object's composition
If gaskets are sandwiched between ends of cylinder body and covers, then falling off is prevented, but assembly ease is reduced
Solution Approach 1:
The damper structure is segmented into a main body and a retaining member. The retaining member is specifically designed to engage with the side surface of the cover member, allowing for easier assembly compared to sandwiching gaskets between multiple components.
Solution Approach 2:
The retaining member acts as an intermediary element that connects the damper to the cover member's side surface. This intermediary structure simplifies the assembly process by providing a clear engagement path, unlike the complex sandwiching method requiring precise alignment between multiple components.
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 design enhances damper retention and assembly ease, preventing falling off and maintaining effective sealing while absorbing shocks, thus improving the overall performance and usability of the fluid pressure cylinder.
Implementation Method 1
the retaining member is gripped between the side surface of the cover member and an inner wall surface of the cylinder body
Implementation Method 2
a damper disposed on the cover member, which absorbs shocks when the piston abuts against the cover member
Implementation Method 3
the dampers, which are formed from elastic materials, are compressed and deformed

AI summary
A fluid pressure cylinder including a first damper and a second damper provided respectively on a head cover and a rod cover, which are disposed on both ends of the fluid pressure cylinder so as to face toward a piston. The first damper and the second damper are formed from an elastic material, and are made up from a main body portion against which the piston abuts, and a plurality of legs that project from the main body portion and which are gripped between the head cover and the rod cover and an inner wall surface of the cylinder tube.
