Purchase a couple of Pico USB flash drives to determine minimum size and overall dimensions.
Things to notice: No visible hardware on pico drives; everything is encased inside a plastic housing. Much smaller than more traditional USB drives.

Understanding the basic principal of how locks works will help us figure out how to make the USB drive functional.
How do Locks Work?

Bike Locks are interesting because they have no pins and rely on a customizable key combination to solve the lock.
Some initial problems in implementing this to the USB flash drive:
Metal connections “contact points”Customizability Security of Hiding the Key from others

The BadMany USB flash drives fall under the “bulky” category where you are unable to use multiple drives or devices
The GoodThe benefit to Pico USB flash drives is that they allow you to easily use multiple drives without affecting surrounding ports.

Looking at a mechanical function to activate the “Set Code” feature.

The mechanical function is the toughest portion of this device. They have to be able to lock, set, and reset the numbers to the users liking. And, they must also carry the conncetion to complete the circuit for the flash drive.

Another approach would be to go completely digital (but still input dependent). You can set the code with no mechanical parts and the code set is then the key to unlock the drive.

Initial concepts for both the mechanical and digital combination locks. Color combination could also help distinguish the aesthetics of the device among competitors.
Next, play with different form types like: aggressive, feminine, sleek, retro, ruggerd, etc.

Some problems yet to be solved are: wiring the tumblers to recognize a solved key, keeping the chambers fixed in space, and also adding a spring mechanism to keep all the internals spring loaded.

The edited version of the of the lock drive received modifications like a the brace sleeve to help both hide the combination key and to strengthen the overall housing.
Edited 3D Model
Also, the overall length of the device has been exntended to fit the necessary internal mechanisms.

An internal spring mechanism has been added to keep the tumblers under tension.
The back housing has been modeled to hold both the LED emitter and the release mechanism for the pull tab that guides the main pin shaft.

A glance of the internal makeup of the lock drive. It features a larger pin shaft with larger tumbler pins. The tumblers are also larger and act as a track for the chambers and the dials.
The dials also now use the binary code numbering system to help steer away the average Joe. Recessed holes could possibly light up using a semi transparent plastic and a backlight LED to light.
The Spring mechanism is situated in the front housing and is kept in place with a spring bushing (washer) that is compressed against the housing. The spring sits around the main pin shaft and is capped at the end with a screw.

26Abraham PetersEdited 3D Model
Now, instead of using contact points to complete the circuitry, the use of an LED emitter and a photodetector will be used to complete the circuit. Adding dedicated holes throughout the tumblers, chambers, and placing the hardware at both ends of the device will allow the LED and photodetector to communicate with each other to complete the circuit. This still allows the combination to be customized.

The new redesigned body brought forth a simplified body that minimized the housing parts from 6 to 2. This makes the body stronger and even more robust.

Using a photodector and a IR LED, the lock drive only works when all the tumblers are in line.
If even one tumbler is not lined up, the thumb drive will not work.
