Project 1: Form and Function

The aim of the project is to create a bridge with an adjustable opening for a 30ft x 40ft object to pass through. There must be a mechanism that has to be incorporated which will change the final bridge design. Alterations to the form of the bridge can only be made if there is a functional requirement. Symmetry is not allowed in the final design. My prototype was altered to take out a section of the arch bridge which allowed for a moveable part to be raised when the object passed. The mechanism will be within the tower. It must have a 190 ft spawn, no supporting structures on the water, with road 10ft above water, and all membranes of the bridge must not pass 20ft.

Preliminary Designs:

The Preliminary Prototype designs consisted of both having an arch bridge foundation, however, one being based on a magnetic clip while the other being based on the BB gun loader.

Arch Bridge with Magnetic Clip | Arch bridge with BB gun loader

Transformation Process:

However, at the end I combined both prototype, resulting in a wine opener as its main idea

Elevations:

Open Position | Closed Position

Conceptual Applications:

BB Gun Loader/Movable Portion

The movement of the gears and counterweight would make the movable portion of the bridge to rise and fall, just a BB gun loader handle would move in and out of its base.

Magnetic Clip/ Lever

This part would count as a counterweight for the function of the gears as it raises and lowers the bride.

Wine Opener/ Gear

This part would count as a stopper as it will slowly but safely raise and lower the movable portion.
