Piston Stop Shock Absorption for Simulation Gun Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Simulation guns face durability issues due to impact on the piston mechanism during air current ejection, which is not effectively addressed by existing solutions that complicate the mechanism and require expensive materials.
Innovation Solution
A shock-absorption device is introduced, comprising a piston stop and a coil spring between the piston stop and the cylinder, allowing the piston stop to move relative to the piston mechanism and absorb impact forces, thereby reducing kinetic energy and enhancing durability without significant changes to the existing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a piston mechanism is used to eject air current to fire a bullet, then the simulation gun can achieve firing function, but impact force is generated causing durability problems
Solution Approach 1:
A shock-absorption means (coil spring or rubber cushion) is provided in advance between the piston stop and cylinder to cushion the impact force that occurs when the piston mechanism operates. This beforehand cushioning prevents direct impact transmission to the cylinder and piston stop, thereby improving durability without changing the basic piston mechanism structure.
2Object-affected harmful factors
If existing shock-absorption solutions are implemented, then impact can be reduced, but the mechanism structure becomes complicated
Solution Approach 1:
The shock-absorption function is extracted as a separate component (shock-absorption means) positioned between the piston stop and cylinder. This extraction allows the basic piston mechanism to remain simple while adding a dedicated shock-absorption element that does not interfere with the core firing function.
Solution Approach 2:
A piston stop is introduced as an intermediary component between the piston and cylinder, with the shock-absorption means positioned between them. This intermediary structure absorbs impact forces while allowing the piston mechanism to maintain its original simple structure and firing function.
3Reliability
If expensive materials are used for colliding members, then durability can be improved, but material cost and machining complexity increase
Solution Approach 1:
The shock-absorption means (particularly the rubber cushion option) uses inexpensive, easily manufactured materials to absorb impact forces. This approach protects more expensive components like the cylinder and piston from damage, effectively extending their service life without requiring expensive materials for the shock-absorption component itself.
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 shock-absorption device effectively attenuates impact on the piston mechanism, improving durability and allowing for reduced size and weight of the bolt, while maintaining the simplicity of the existing structure.
Implementation Method 1
the shock-absorption means is a coil spring provided to be arranged between a spring holder in the cylinder and the piston stop
