Foamcore aperture, Spring 2013

After completing a rubber band cart project in E28 (introduction to engineering graphics), I was left with a fair amount of unused foamcore.

This project was conceived of during the summer, after I moved into an apartment with a window on the door. However, it was put on pause as iterating the kinetics of various aperture blade designs by hand proved to be very time consuming. It was completed during winter break, after I was introduced to Solidworks in the engineering design graphics course.

Despite this being a totally random project, it allowed me to really appreciate the power and iterative speed of solid modeling softwares.

Completed and mounted on the apartment door.

Iterating the movements of aperture blades of varying sizes. Some initial blade shapes on trace paper.

Into the digital world! Final model in Solidworks.

'Templates' of aperture blades printed out directly from solid model drawing files. The sharp corners were later rounded out for a smoother opening/closing action.

Almost there. I initially intended to sandwich the aperture assembly with another sheet of foamcore, but decided on extending the guides for the 'ring' (circular piece that actuates the blades) to constrain the components in the plane.
