1. Credit Card Organizer Alex Jury David Turner EN100 Spring 2006

2. Introduction Why make a credit card organizer? 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.

3. Design Process: Preliminary 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. 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.

This design required the user to apply some of the force needed to dispense the card.

4. Final Design The mechanism to release the card is spring-loaded. The mechanism to release the card is spring-loaded. The part which holds the card moves along a track without wheels. 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. 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. The cardholder part is held in place by a platform consisting of a vertical triangular lip which is released when the button is depressed.

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

6. Design Aspects Button Mechanism The button is spring- loaded as well. 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. 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. The spring forces the button back to its normal position.

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

8. The holder houses the card in a similar manner to how money clips work. 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.

9. Design Issues and Improvements Button Sleeves The original design of the button sleeves (top) were simple hollow cylinders that were very fragile and broke easily. 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 Improvements Back Spring Constraints These parts (top), which keep the back springs in place, were also built too thin and broke easily. 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.
