Air Spring Pin Fixing via Vertical Guide Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air springs face difficulties in securely fixing pins due to obstructed horizontal space, making the operation of using a split pin challenging.
Innovation Solution
The air spring design incorporates a guide member attached to the handle, allowing the positioning member to be inserted vertically, eliminating the need for horizontal pin insertion and providing a more accessible mechanism for securing the pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a split pin is used to prevent pin dislodgment in conventional air springs, then the pin can be secured, but the horizontal space obstruction makes the insertion operation difficult and complex
Solution Approach 1:
The patent changes the insertion direction from horizontal to vertical by introducing a guide member that extends in the vertical direction. The positioning member is inserted vertically through the guide hole in the guide member into the positioning hole in the inner cylindrical member, avoiding the obstructed horizontal space and making the operation easier while maintaining secure fixation
2Stability of the object's composition
If pins are inserted horizontally through the handle in conventional air springs, then the handle can be fixed to the holding body, but the obstructed horizontal space makes the operation challenging
Solution Approach 1:
The guide member extends vertically from the handle and provides a guide hole that directs vertical insertion of the positioning member. This vertical path avoids the horizontal space obstruction caused by the bellows and other components, making the positioning operation easier while maintaining stable handle fixation
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
This design simplifies the operation of preventing pin dislodgment, enhancing the ease and reliability of fixing the pin, thereby improving the overall functionality of the air spring.
Implementation Method 1
an air spring making use of elasticity of compressed air has conventionally been known
Implementation Method 2
a stopper assembly arranged in the internal space as being pivotable over the inner cylindrical member, the stopper assembly allowing suppression of movement of the outer cylindrical member toward the inner cylindrical member
Implementation Method 3
a positioning member attached by insertion in a guide hole in the guide member for positioning of the handle, a positioning hole provided in the inner cylindrical member which can receive the positioning member

AI summary
An air spring includes an outer cylindrical member, an inner cylindrical member, a diaphragm, the diaphragm providing an internal space between the outer cylindrical member and the inner cylindrical member, a stopper assembly arranged in the internal space as being pivotable over the inner cylindrical member, a handle for pivoting the stopper assembly over the inner cylindrical member, a guide member attached to the handle as rising from the handle, a positioning member attached by insertion in a guide hole in the guide member for positioning of the handle, a positioning hole provided in the inner cylindrical member which can receive the positioning member, and a holding mechanism in the inner cylindrical member. A position of the stopper assembly with respect to the inner cylindrical member is determined by inserting the positioning member in the positioning hole.
