Functional Components
 Contains three different
processes:
 Energy Processing
 Material Processing
 Signal Processing
 Each process contains
different components
that enable the camera
to function accordingly.

Energy Processing
 Divided into three components:
 Light
 Electrical
 Mechanical
 Each lower component can be subdivided further

Flash charging
 Flash discharge
Mechanical
 Divided into three components:
 Cock shutter
 Advance film by one frame
 Open shutter
Material Processing
 Operates by:
 Advance film and wind up shutter
 Frame counting
Signal Processing
 Operates trigger by:
 Trigger shutter open
 Trigger flash discharge
 Operates flash by:
 Turn on flash charging
 Flash ready signal
Materials Used for Parts
 Camera unit as a system:
 Previously used components
 New Injection molded plastic parts
 New Metal components
 New Printed Circuit Board Assembly of the Flash unit
 New Batteries for the Flash subassembly
 Film rolls in canisters
 Packaging
Disassembly Procedure
 Take apart the plastic housing covers. Use a small
screwdriver to pry rear and front sections off. Be firm,
but gentle. The pieces should come apart without
breaking. In the rear of camera body you will see the
film chamber and the flash battery, in the front you’ll
see the lens with shutter and the flash circuitry-do not
touch it yourself.
Removal of AA energy cell
 Identify and remove the AA energy cell from the
camera. Remove the exposed film cassette and put it
away for processing later.
Assembly Procedure
 Wind the shutter up by turning the sprocket whelel (above film
window) until you hear a firm click. Turn the front of the camera
away from yourself and others. Press the shutter to discharge the
remaining power in flash circuit.
Final Disassembly
 Take apart the camera mechanism as far as possible in
order to discover principal compents.

Assembly Procedure
 Reverse the process you took in taking the camera
apart.
 Carefully put each component back into the camera.
 Lastly, put the plastic cover back on the camera.
How does the camera work?
 When the user is ready to take a picture, she simply
aims the camera at the desired subject and presses the
shutter-release button. This button activates a springloaded shutter in the side of the camera which flicks
open for a fraction of a second; the exact length of
exposure depends upon the shutter speed of the
camera

Recycling
 Ironically, disposable cameras are anything but
disposed of. In fact, the recycling industry for
disposable cameras has surpassed that of aluminum
beverage cans. Retailers are incentivized and provided
with services to increase their willingness and desire to
help Kodak recycle the single use camera. Among
these services is a silver management service that
includes refining, recovery, and recycling. This service
is primarily concerned with recovering the silver from
developed and therefore unnecessary film.

The Circuit Board
 One of the most important components recycled is the circuit board. The
ability to reuse this piece is fundamental in making the recovery process
economically viable. These boards are tested to ensure quality, and then
reused. Being that the camera components are tested to ensure quality,
Kodak no longer considers tracking the number of times they have been
reused relevant. It is not unheard of for this component to be reused ten
times.

Other Reusable Components
 Like the circuit board, the plastic frame, and associate plastic components,
are also reused after quality has been assured. The frames are reused and
average of three times, and have been specifically designed to be reused. In
fact operating instructions are printed on recyclable polystyrene panels,
which subverts the need to augment decals. The only plastic component not
regularly reused is the lens, which is ground up, and designed using easily
recycled plastics.

Packaging
 The recycling process for single use cameras is so
developed that they are also associated with specific
facilities dedicated to recycling the paper packaging.

Reduce Waste
 Improving the durability of the circuit board itself, the
key component in making the recycling process
commercially viable, would lead to increased reuse
and overall minimization of input materials
 Fewer, in terms of reconstitution, more durable items
would lead to increased lifetime of the component,
and minimized expenditures for the corporation.
