Solution Overview
Problem
Gas springs used in sheet shaping processes face horizontal oscillations due to floating plates or die vibrations, which existing solutions like spherical surfaces or sliding elements either deform the die or reduce operational stroke.
Innovation Solution
A gas spring design featuring a hollow cylindrical body with a piston rod and a laterally displaceable sliding element connected via a connection means, allowing absorption of perpendicular movements while maintaining force direction and facilitating maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spherical surface is used on the end of the mobile axis to permit slope oscillation and reduce friction, then the absorption of perpendicular movements is improved, but the die surface is deformed and operational stroke is reduced
Solution Approach 1:
The connection between the piston rod and die is segmented into two independent functional elements: a spherical surface for absorbing perpendicular movements and oscillations, and a separate guidance mechanism (rails or guides) for maintaining precise vertical alignment. This segmentation allows each element to perform its specific function without interfering with the other, preventing die surface deformation while maintaining adaptability.
Solution Approach 2:
An intermediary guidance mechanism (rails or guides) is introduced between the spherical surface and the die to mediate the interaction. The spherical surface freely absorbs perpendicular movements, while the intermediary guidance element ensures that the vertical movement remains precise and does not deform the die surface, thus resolving the contradiction between adaptability and manufacturing precision.
2Ease of operation
If spherical surfaces are used to reduce friction and permit oscillation, then the ease of operation is improved, but the operational stroke is reduced due to surface deformation
Solution Approach 1:
The connection system is segmented into a spherical surface component for friction reduction and oscillation absorption, and a separate guidance component for maintaining stroke length. The spherical surface provides ease of operation by reducing friction, while the guidance mechanism ensures that the full operational stroke is maintained without loss due to surface deformation.
Solution Approach 2:
An intermediary guidance mechanism is introduced to mediate between the spherical surface and the moving components. This intermediary ensures that the spherical surface can reduce friction and permit oscillation without compromising the operational stroke, as the guidance element maintains the correct geometric relationship and prevents stroke reduction.
3Stability of the object's composition
If sliding elements are inserted into a mechanized box to absorb perpendicular movements, then the stability is improved, but the device complexity increases
Solution Approach 1:
The complex mechanized box with sliding elements is replaced by a simple spherical surface at the end of the piston rod. The spherical geometry inherently provides the ability to absorb perpendicular movements and oscillations through its curved contact, achieving the same stability function with much simpler construction and fewer moving parts.
Solution Approach 2:
The design changes from a complex mechanized box structure to a simple spherical surface by changing the geometric parameter of the connection element. This parameter change (from box-like structure to sphere) maintains the ability to absorb perpendicular movements while dramatically reducing device complexity.
