Abstract

There are a variety of methods to assemble an actuation button to a valve assembly. Typically they are configured as a press fit. The usage of interference between the male feature and female feature, make it susceptible to breakage if the alignment between the 2 features are misaligned. The process to press a post feature into a hex feature, make the process more expensive with assembly fixtures, complex tooling, and inefficient labor ergonomics. These are several ideas that describe simpler features to aid in the assembly of the button to the valve assembly, some without expensive assembly fixtures, or the need for more complex tooling.

Improved Button to Valve Attachment

Summary

Problem statement:

There are a variety of methods to assemble an actuation button to a valve assembly. Typically they are configured as a press fit. The usage of interference between the male feature and female feature, make it susceptible to breakage if the alignment between the 2 features are misaligned. The process to press a post feature into a hex feature, make the process more expensive with assembly fixtures, complex tooling, and inefficient labor ergonomics.

These are several ideas that describe simpler features to aid in the assembly of the button to the valve assembly, some without expensive assembly fixtures, or the need for more complex tooling.

Description

One solution, the valve could be configured to have a t-shape head, which would mate with a ribbed pocket. This can be assembled manually, without the need for a press.

The shrouds will keep the engagement by not allowing the button to shift in a direction that would allow the button to disengage.

Another solution is to mold a snap feature into the button. This would require holes in the inside of the button to allow molding of the undercut. A receiving slot for the snap would be molded into the valve, as well as a clocking feature in the bottom surface. The clocking feature can be a non-symmetric shape of the bottom surface, or a shape molded into the valve.

Another solution is to mold a headed pin onto the valve. The but...
