Aim of the Project
The aim of this project is to disassemble a Polaroid disposable camera and to then reassemble the parts while reporting observations. Cad drawings are going to be used to show certain, important parts of the camera. After observing how the different components work in the camera, improvements will be suggested.
Description
The product is a one-time use disposable, camera with flash manufactured by Polaroid. Majority of its parts, being made of ABS Plastic and by injection molding.
Disassembly
The following where the main features noticed during the disassembly process.
•Remove the cardboard covering.
•Remove 1 screw which held the back and the casing together. The screw was located beneath the view finder.
•Then we seperated the back and the front covers, which were fastened by Plastic fasteners.We also observed that these plastic fasteners were used extensively throughout the camera to keep components locked to each other. We figured it was a good way to reduce production cost.
•We had to take out the battery to prevent short circuit, and for safety purposes.
•We then took out the cover which protected the film housing, and then took out the film.
•Then we popped out the view finder.
•To have a closer look at the circuit board, we had to remove it by unscrewing the smaller screws were used to keep the circuit board in place
•After taking out the circuit board we could have a closer look at the spring amd sprocket component in the camera. which rolled the film and changed the film count, using gears.
•Black Plastic cover was used to keep light out, so that it wouldn't damage the film.
Outer Components
The Front Exterior of The Camera
The outer casing is made of ABS plastic, and manufactured thru Injection Molding. As shown in the picture, The front exterior houses 7 major components, namely:
•View Finder: The user sees the scene for the picture thru this.
•Flash: It is powered by the battery.
•Flash Button: It charges the Flash with the power from the battery.
•Lens: It lets the light in, and the shutter, placed behind the lens, exposes that light to the film.
•Lens Holder: It keeps the lens in place
•Film Casing: the lid for the film
•Film Advance Wheel: it rolls up film into the "Film Canister" and clicks off numbers on the "Frame Counter."
The Back Exterior of The Camera
The outer casing is made of ABS plastic, and manufactured thru Injection Molding. As shown in the picture, The back exterior houses 2 major components, and 1 feature.
•View Finder: The user sees the scene for the picture thru this.
•Film Advance Wheel: it rolls up film into the "Film Canister" and clicks off numbers on the "Frame Counter."
•Grip: Its a feature in the back cover, which allows users to have a better grip on the camera.
The Upper Exterior of The Camera
•Frame Counter: Gives the number of frames (Pictures) taken
•Shutter Button: Activates the shutter, which exposed the light to the film, hence taking that picture.
•Flash Ready Button: Shows when then flash is charged and ready.
•Vent: For ventilation of heat.
The Lower Exterior of The Camera
•Film Casing Cover: It is the cover for the film compartment.
•Film Swindle: It it rolls the Film.
