Introduction

• Why make a credit card organizer?
• - easy access to several credit cards and/or
  I.D. cards.
• - useful at airports during security checks,
  places of business where I.D. cards are regularly
  checked, and for everyday shopping.

Design ProcessPreliminary Design Concepts

• Original idea involved a mechanism in which a
  button was pressed and moved in the direction of
  the card motion, thus pushing the card out. This
  design required the user to apply all the force.
• - This design also involved the part which held
  the card in place to move along a track with
  wheels.
• Another idea involved pulling on a lever on the
  side of the cardholder, which would supply a
  force that would push the card out. This design
  required the user to apply some of the force
  needed to dispense the card.

Final Design

• The mechanism to release the card is
  spring-loaded.
• The part which holds the card moves along a track
  without wheels.
• Holds two cards, each one controlled by a
  different spring-loaded push button.
• The cardholder part is held in place by a
  platform consisting of a vertical triangular lip
  which is released when the button is depressed.

Design AspectsRelease Mechanism

• The card is held in place by a part that slides
  along tracks on each side.
• Springs behind the holder part push it out when a
  button is pressed.

6
Design AspectsButton Mechanism

• The button is spring-loaded as well.
• Depressing the button will force the shaft down a
  small amount, allowing the cardholder part to pop
  out.
• The spring forces the button back to its normal
  position.

7
Design AspectsLocking Mechanism

• A triangular tooth on the bottom of the button
  part prevents the card from moving until the
  button is pressed down.
• When holder is pushed back in, it slides over the
  tooth and then clicks back into place.

Design AspectsHolder

• The holder houses the card in a similar manner to
  how money clips work.
• On the back of the holder are two hollow
  cylindrical pieces that house the springs used to
  push the part out.

Design Issues and ImprovementsButton Sleeves

• The original design of the button sleeves (top)
  were simple hollow cylinders that were very
  fragile and broke easily.
• During the manufacturing process, the design was
  improved (bottom) by attaching the sleeves to the
  main part.

10
Design Issues and ImprovementsBack Spring
Constraints

• These parts (top), which keep the back springs in
  place, were also built too thin and broke easily.
  
• A better design (bottom) is to simply use
  cylindrical pegs that can constrain the springs
  from moving laterally.

The Next Step

• Possible applications involve making a similar
  device that could be built into a briefcase or
  purse.
• Perform a patent search to determine if invention
  is unique and could qualify for a patent.
