the Compact Wallet - GD Consulting LLC

Designed for portability and based on the premise that a wallets primary purpose is store cash, credit cards, and a few other miscellaneous card size items, the compact wallet is worth exploring. It places easily into pockets and backpack, and is study enough to figet with upon use; tap it on a table, twirl it between thumb and forefinger, release and snap the lid back in place. Give it try.

An Informal DFMEA (Design Failure Mode Effects Analysis)

Functions:

Hold Stuff, Allow easy Access

Failure Modes:

Fracture, Unplanned Open, Lock Out user

Effects:

Catastrophic failure, inconvenience, dissatisfaction

Prevention

Material Selection (PETG) & Wall Thickness, Snap lock features on lid, contents protrude body for access

Detection

Field Servicing testing. It is noted that the compact wallet lacks arrayed access to contents as do standard wallets.

It may take a little time to appreciate. As noted in the DFMEA, it requires some coordination to quickly access a card or cash in the center of the stack. In a standard wallet, the items are arrayed, so and individual card is easily picked. In the compact wallet, they are stacked, making it necessary to remove the stack when a seldom used card is needed. As a residual risk, it probably takes a few extra seconds to retrieve an item in the center. This is a minor inconvenience that is outwieghed by the wallet’s compactness, because a wallet is carried for a significantly longer time than it is acessed. For this reason, you should place your most frequently accessed items on either side of the stack, in which case, the card is easily and quickly removed, used, and replaced.
