Our Product: Fuji Quick Snap Disposable Camera


Contents

Executive Summary

  • This page is dedicated entirely to the Fuji Film Quick Snap Outdoor camera. This camera, which was first introduced in 1986, was a bench mark for other companies. Competition and environmental needs lead to the development of the modern Quick Snap Outdoor Camera. Our objective was to gain intrinsic knowledge on the inner workings of the Quick Snap camera. How was it manufactured? Why was it done this way? How does it work? Does the camera seem recyclable? In order to meet this objective, we initially observed our product and made some basic speculations as to the number of components and their function.
  • After that, we completely disassembled our camera. The disassembly was fairly smooth, and no tools were needed. The snap fits on the camera allowed us to just pry the camera apart. The rest of the inner pieces were pretty easy to remove. Keep in mind this is a disposable camera and these parts were not made to endure much. Once the camera was completely disassembled, we could evaluate each piece to see how it was made, what it was made from, and what each part’s function was. This is all listed below.
  • We then proceeded to put our camera back together with the goal of having it be functional again. However, whether or not our camera truly works properly will be unknown since we had to use all of the film in order to get it into the film cartridge. Without doing this, the film would have proved to be an obstruction.
  • To conclude the project, we took what we learned to make a few suggestions and deductions on our product. These are listed in the After Assembly section. Overall we found our product to be well made. It was apparent that Fuji made this design with their budget and the environment in mind. On the back of the outer casing of our camera was a warning for electric shock. After opening our camera we realized that there was no power source, and concluded that Fuji used this casing for various styles of camera. This is smart since it saves them money; they have fewer molds to make. Also, Fuji is working to perfect the “inverse manufacturing” process which means that they either re-use or recycle all of their parts. The camera, although simple, had a lot of thought behind it.

Introduction

The Fuji QuickSnap Camera Outdoor is the most basic Fuji model consumers can buy. This camera has no flash, no special lens, but only the latest in technology for film, the ISO 800. Obviously technology has advanced since then, but this camera was the first of its kind. This camera was built for people that don’t want to pay for extra features they don't need. This lightweight simple to use camera comes with 4 easy steps right on the cardboard cover.

Before Disassembly Section

  • The purpose of this product is for the consumer to easily capture images. The consumer takes their 27 shots, then brings it to a place that develops photos, and in as little as an hour they have their pictures! This product was designed to be simple and easy to use. Along with function ability, the disposable camera was made so that it could be sold at an inexpensive price. This way it targets most consumers. These features allow the disposable camera to compete with the digital world. Consumers who are concerned about breaking their digital cameras, or who can't afford one can easily turn to the disposables.
  • Since this camera is so inexpensive we have to believe that all of the energy conversions are mechanical. Also, since there is no flash feature there is no need for electrical energy. When the consumer advances the film, they transfer their energy to the wheel which in turn mechanically transfers its energy to another device in the camera. However, since we have yet to disassemble the camera, it is hard to know for sure what exactly happens.
  • We received a completely brand new camera and it worked perfectly. To use the camera, all we had to do was advance the film wheel, point and shoot. When you advance the wheel it makes a clicking sound. When you push down on the button to take the picture it makes a click sound. It was simple and easy to use and appeared to have no issues.
  • By knowing the basics of how a camera works, we can make an assumption on how many components make up the camera. We know there must be the advancement wheel, the film, the two outer casings which make the camera, a track for the film to follow, the lens, a shutter, the button, a device that transfers the kinetic energy from the wheel to the film, and a device from the button to the shutter. Overall we can approximate about 14 components. This is making the assumption that each of the inner "devices" are composed of at least 2 parts each.
  • By looking at this product we can tell that it is mostly made out of plastic. The basis of the camera is made of a thick black plastic while the lens and the view finder appear to be made of a clear plastic. Also, there is a cheap cardboard cover over the camera that serves the purpose of aesthetics, advertisement, and liability protection.

Disassembly

Before beginning, check to ensure the film count reads "0". This will guarantee the film is enclosed in the canister and will not interfere with the disassembly.

  • Note: Only human hands were used as tools for this disassembly. There was no need for anything else.
  • Disassembly took about an hour, this could have been done faster but care was taken to prevent breaking the components.

After Disassembly

  • The marking on the plastic casing indicates that the product is made of Polystyrene. This is plausible since PS is naturally colorless by nature and can be used in molds of fine detail. However, we found a sustainabilty report from Fuji saying that Polyethylene was a material that they used. This too is possible since this is commonly used and is very similar to PS. This is why we listed Thermoplastics for all of our plastic parts.
  • Also, since music wire is one of the most common, and cheapest wires to use for springs, we used this as our material.
  • We were able to tell how each piece was made mostly by just appearance. Most of the plastic pieces had the "dot" where the injection process would occur. Also, for small, thin, intricate parts it makes sense that some of these pieces were injection molded. Some of the pieces had a little tab left on them. This indicates that they were inevestment casted. This way the company could make multiple pieces at one time. For the film canister, a basic metal tube is normally extruded. Then the ends have to be attached somehow. Since this needs to be a tight seal in order for light not to enter, we assumed that ultrasonic welding was used. This also concurred with one of our fathers who works for a film company.

  • The only major modification to the disassembly steps was to wait until the end to resecure the back casing. This provided additional working room while performing the other steps.

After Assembly

  • After completely disassembling the Fuji Quick Snap Camera and evaluating each piece we now have a clearer view as to how this camera works. 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. Not only does this wheel advance the film, it also has
  • 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.
  • There are various computer programs available that could be used to develop accurate models of our camera. If we want a model to see how our pieces fit together, Solid Works, Inventor or AutoCAD are a few programs. Various types of stress strain data loggers could be used to test the stress on the picture button.
  • These models would have to be pretty accurate. Not only would an accurate model save you money when you are designing your parts, but it could be the difference between your part failing or passing. Since we are working with small pieces, we want their shape, their material, and their exact forces. If you estimate too much with the model, you may make a design that fails completely in real life.
  • The disassembly and the reassembly were basically a reverse of each other. No additional tools were needed for either. The only difference was that during the reassembly, we waited to put the back casing on. Since the back casing didn't hold any parts, it only took away space. Obviously we were not able to pull the film back out. Aside from the fact that we would have to break the canister open, the film would have been exposed already. The only other thing that did not go back on perfectly was the cardboard casing around the camera. This casing had the 4 easy steps instructions along with the Fuji film advertisement. If we were to use some glue I'm sure we could attach it back on.
  • Since it has been a while since this camera first came out, there has already been many advancements in the disposable camera world. First off, companies don't even call these "disposable cameras" anymore. They call them "one time use cameras." This is due to the fact that Fuji along with other companies are working on making the one time use camera completely re-usable. The lenses are examined and re-used if possible. If not, they are turned back into pellets ready to be molded again. The black plastic parts are either sold or turned back into pellets as well. This allows the company to save tons of money by re-using their parts along with reducing their emissions. These parts are already made of cheap plastic so we can't suggest a change in material. The lay out of the pieces inside the camera is pretty good. They are located right by each other so they don't waste parts material. Also most of their parts are multifunctional, so we can't compact their systems.
  • Our next step would be to look at the design. We would suggest that a flash be added so that the camera could be used indoors. This has already been done. Also, we would say reduce the shape of the camera since there appears to be a lot of wasted space, but then you would not be able to interchange this camera "base" with other styles of cameras. There are many other features that we would suggest to add that have already been done. This would be underwater ability, a disposable digital camera, a panoramic feature, special customized films such as black and white, and even different casing colors. When it comes to the film, we suggest that there be more pictures available. Sometimes 27 exposures is not enough. Also, since these cameras are mostly used by tourists, they should come on a carrying case. This case could have a clip so that it could easily attach to a belt loop or purse strap. The case would also serve as a means of protection from particles like sand.
  • Overall, we would make the recommendation that a lens wheel be added. This wheel would have various lenses of different magnifications. This way, the consumer could choose various "zooms." This would obviously increase the cost of production, but would add appeal to the consumer. We would also suggest that a small more compact model be made. Even though you won't be able to interchange the base camera molds, this product would be very attractive to the consumer. Everyone wants the most compact objects they can buy. This is so that they can keep these objects in purses or pockets. There is at least about 1/2" that could be take off the camera's length. As for environmental issues, Fuji has been consistently working on improving the amount of their cameras that they recycle. Today the new QuickSnap 1000 is over 90% reused or recycled when returned to the company. In 2002 Fuji developed the FUJIFILM Group Green Policy. This policy ensures that Fuji is working to consistently improve their factories and products to better help the environment.
