Group 12 - Fuji Waterproof Camera

Executive Summary
Introduction
The Fuji Waterproof Disposable Camera is a product designed to be user friendly, simple and easy to use under harsh conditions. The camera works just like any other conventional film camera whereby light enters thru the main lens and the image taken gets exposed on a film. The only difference between a normal camera and the disposable camera is that the latter has no power source and all of the parts work mechanically. The other distinct difference is that it also has waterproofing capabilities up to a specfied depth. The disposable camera is design for a single use with the film providing 27 exposures per use. The design of the whole system makes the camera robust and tough for outdoor activities.

Before Disassembly
Fuji Waterproof Camera is a disposable camera, which is waterproof so that you could take pictures under water. Just like any other film cameras, light reflected by objects enters through lens and when shutter is opened, it is exposed to the film which then image is recorded. Electrical energy is used in order to operate flash. Electrical energy is charged and released as a light form. Mechanical energy provided users are converted to another form of mechanical energy, which opens shutter for set amount of time.
When the product is operated, it gives click sound and the shutter quickly opens and re –shut back to its original position so that it does not let through any more light to the film. After each shot, it is required to spin film spindle for certain amount so that film is moved to new area and another photo could be taken. The mechanism is fairly simple, that is repeated process of taking a shot and reloading.
It is predicted that it consists of at least 30 parts other then the cases. Also, the materials are made out of metal for springs, plastic for majority of components, glass for lens and possibly rubber for seals inside. So the prediction is that there are 30 components, consisting of 4 different materials.
Disassembly Procedure
After Disassembly and Table for Parts
The table belows lists the Bill of Materials for the disposable camera:

Improvements
The camera was convenient and easy to use with a few changes which could have enhanced the product.
1. The Front Waterproof cover has a rubber attachment grip on the right hand side of the camera. The purpose for this, is to avoid slippage. Common practice while taking snapshots, is to hold the camera with two hands and not one. It would be a reasonable improvement to have rubber grips on both sides of this part.
2. The Viewfinder allows the user to see what snapshot is going to take place before the trigger is executed. Unfortunately, the physical photo when developed, is not consistent with what the viewfinder was showing the user before the picture was taken.(according to Amazon.com's Product Evaluation) Inscribing the virtual photo to the viewfinder would give the user more feedback before taking the snapshot.
3. Front and back view finder could have been combined instead of being two separate components which makes life harder.
