First, the consumer has to advance the wheel so that the film will be in its proper place. When you spin the wheel, the gear design embedded in the bottom part aligns with the gear pattern in the film cartridge. Spinning the wheel advances the film into the cartridge. The film has small squares cut into the side of it.  Inside the camera is a small white gear that the film runs on.  We were unable to take this gear out since it appears to be molded in there.  When the film runs over this gear, it turns which rotates our spindle.  The spindle has a notch cut into the top piece so that it lines up with the counter wheel.  The ratio of diameters from the gear to the spindle is made so that when one complete square of film has passed, the counter counts down one picture.  The spindle also cocks the shutter.  Below the notch for the counter wheel is another notch which is for the advance lock.  When this notch lines up with the lock, it slides into places and prevents the consumer from advancing more film.  There is a torsion spring which is constantly pushing the advance lock against the spindal so that it always locks.  This sping also puts force on the shutter trigger.  The spring keeps the shutter trigger from hitting the shutter release.  Now, when the consumer pushes the button, there is a cantilever attached to it.  When the button is pushed down, a lever pushes to the left (holding the camera as if taking a picture).  This lever pushes the shutter trigger over.  This trigger quickly goes over the shutter piece which opens the shutter, and the tension spring that holds the shutter closed, quickly closes it.  The shutter trigger is push back into place by the spring, and the camera is ready to go again.
 *Our product appears to work the same as it did when we started. However, since all of the film was wound into the cartridge, we can't tell for sure. When we spin the film advancement wheel it rotates and makes the same clicking sound.
 *We could use the analysis steps for various parts of our camera system. We could use analysis to figure out the stress in each mechanical part, the approximate cost for our materials, what force is needed to set our system off, and so forth. The seven general analysis steps would guides us in our investigation (1.Problem Statement, 2.Diagram, 3.Assumptions, 4.Governing Equations, 5.Calculations, 6.Solution Check, and 7.Discussion). We could use these steps to test the maximum strength in our springs and see what their life cycle would be. Obviously, as the manufacturer you would have to make assumptions based on what you think your consumers will do. We would have to assume that the consumer isn't going to push the picture button as hard as they can, every time they rake a picture. Also, we would have to assume what kind of wear and tear was going to be inflicted on our camera so that we could see what kind of plastic to use and how thick it should be.
