Group 12 - Fuji Waterproof Camera

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.

After Disassembly

3 changes that could have been made for the improvements are...

1. On the Front Waterproof Cover, it would have been very convenient if there were a thin sheet of rubber stuck on the places where you hold with your hands so that it provides good grip. It would have users life much easier by them being able to hold the camera more easily.

2. Shutter Cover Spring is not very necessary since shutter cover could have a bar, which sticks out through the camera which user can control by pushing in or out. It is true that if it’s got springs, it’s more convenient but since it is a Disposable camera, it will be thrown away after single use. It could have been a wiser choice to make it less fancy and drop the cost.

3. Front and back view finder could have been combined instead of being two separate components which makes life harder.

Due to the lack of space, other files such as Table for parts and CAD drawings are listed below separatly so that it is easier to read.

Table for Parts

The table belows lists the Bill of Materials for the disposable camera:

Table 3.1: Disposable Camera Bill of Materials

Part #	Part Name	# Req'd	Mat'l	Reason of Material Used	Manufacturing Process	Method or Tools Used and Ease or Difficulty of Disassembly	Image
