Group 12 - Fuji Waterproof Camera

Revision as of 01:36, 7 December 2006

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

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	The Reason why it looks the way it does	Image
1	Paper Case	1	Paper	Fairly cheap, easy to produce, More durable and stronger than plastic	Printing and Folding	Rectangular boxes are easy to stack up or storeIn boxes. Also one side of the box being longerthan the other 3 helps the product easy to bedisplayed in shops.
2	Plastic Packing	1	Plastic	Very cheap, easy to produce, since outter box already had durability, no need to have thick wall for inner one		It is in a such shape that it’s good enough to Make secondary barrier for the cameraAs well as is easy for the customers to open
3	Waterproof Strap	1	Plastic	Light and Waterproof	Plastic Shaping	Long strap so that people can wrap around handMultiple times to get a good grip on it
4	Front Waterproof Cover	1	Plastic	Light, Waterprrof and gives good transparent feeling as well. If Glass was used, it would be more costy, heavy and fragile.	Injection Molding	Middle is nearly fully transparent so that it providesOpen view for the lens, the rest is semi-transparentSo that customer would know the Camera’s in the Cover without actually opening up.
5	Back Waterproof Cover	1	Plastic	Light, Waterprrof and gives good transparent feeling as well. If Glass was used, it would be more costy, heavy and fragile.	Injection Molding	Need to be fully transparent because there areMany things to be read from the camera such asHow many shots are left.
6	Waterproof Seal	1	Rubber	Best material since it has low production price yet provides more than enough force to tighten things together.	Injection Molding	So that they can fill up the gaps between the coversAnd keeps camera under the waterproof condition.
7	Shutter Release Arm	1	Plastic	Cheap and easy to produce since Plastic is very easy to be used in Injection Molding	Injection Molding	So that it’s easy for users to open and close withIndex finger.
8	Film Spindle	1	ABS Plastic	Cheap and easy to produce since Plastic is very easy to be used in Injection Molding	Injection Molding
9	Shutter Release Clip	1	Plastic	Cheap and easy to produce since Plastic is very easy to be used in Injection Molding	Injection Molding	It’s exact size to be used more easily
10	Shutter Release Seal	1	Rubber	Seals and insulates well after tightened	Injection Molding	Fits necessary size. It it were too big, it would beToo loose.
11	Shutter Release Spring	1	Steel	Gives strong enough force to function as a spring when shaped.	Steel Shaping	With this shape, it can function as a SpringAnd always provide reaction force to put the Shutter up whenever it is pressed down.
12	Outer Film Spindle	1	Plastic	Easy to mold to produce massive amount of same part	Injection Molding	Can close tight when assembled
13	Outer Film Spindle Seal	1	Rubber	Seals very well after tightened	Injection Molding	Rubber is elastic but still, you cannot have too bigOr too small of a required size.
14	Front Chasis	1	Plastic	maintains its own shape well, fair weight and durability	Injection Molding	Minimum amount so that it just maintains the Shape is needed.
15	Camera Lens	1	Plastic	One of the best material to make transparent parts, less easy to be broken compared to glass, light weight.	Injection Molding	Transparent and curved so that it refracts light wellWhich is the most important part of a Camera
16	Front Viewfinder	1	Plastic	One of the best material to make transparent parts, less easy to be broken compared to glass, light weight.	Injection Molding	Transparent so that user can see through
17	Back Viewfinder	1	Plastic	One of the best material to make transparent parts, less easy to be broken compared to glass, light weight.	Injection Molding	Transparent so that user can see through
18	Magnifier	1	Plastic	One of the best material to make transparent parts, less easy to be broken compared to glass, light weight.	Injection Molding	Transparent so that user can see through
19	Frame Counter	1	Plastic	Provides good grip with high enough friction force when spun with fingers. (Not slippery)	Injection Molding	Transparent so that user can see through
20	Top Film Advance Lock	1	Plastic	Stretches fair amount in order to open and shut. Also creates good "clicking" noise when shut	Injection Molding	It can smudge into exact places to keep parts together
21	Film Advance Lock Spring	1	Steel	Has strong spring constant when shaped into springs which will provide large force to maintain lock	Steel Shaping	Need very strong force to keep locked.
22	Bottom Film Advance Lock	1	Plastic	Stretches fair amount in order to open and shut. Also creates good "clicking" noise when shut	Injection Molding	Elastic plastic is needed to keep it in position
23	Film Advance Gear Trigger	1	Plastic	Easy to be molded, easy and cheap to mass produce	Injection Molding	It must fit into Film Advance gear
24	Film Advance Gear	1	Plastic	Easy to be molded, easy and cheap to mass produce	Injection Molding	Has teeth so that it creates good friction so thatIts is easy for the users to spin
25	Lens Mount	1	Plastic	Easy to be molded, easy and cheap to mass produce	Injection Molding	Once lens goes in the right place, it saves lens

32	Tools used for Disassembly	1	Misc

The camera was convenient and easy to used how ever, there were few changes which could have improved the product.

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.
