Intro – Team Traits

Initial parmeters “Your task is to analyze the current offerings in the market

and design this novel product that meets the Company Lock’s requirements. This lock must meet the needs of the customer better than any other offering on the market.”

Potential ability to scale the idea, Manufacturability, Sell-ability of the product to the masses, Security to uphold its reputation, Ease of use with limited instructions, Must have two unique functions, a key mechanism, and

optional remote controlled.

Alarm System Magnetism Lock App-unlock capability Small enough to be a keychain Stowaway cable (inside the lock casing)

Target SpecificationsAfter browsing competitors and similar products, we

came up with a set of specifications to design our multiple concepts towards.

Approx 10-12mm cable Industry average = 10

1-3 ft cable 3-4 dial combination Push-In lock

Ability to lock without putting in combination

Final Design Sketch

The “Duel Function” Housing and lock mechanism modeled

after bike lockCable is smaller than normal bike lock, mimicking more of a portable snowboard lock.

Added alarm system makes-up for lack of strength of cable

“How It Works”•Available sizes of cable (length)

•Pre-tensioned cable (coils on its own)

•Powered by 2 very small batteries, recharged by a small solar cell, just like the ones used in calculators.

•Pointed end allows lock to engage without putting the combination in initially.

•Tumbler mechanism based on rotating, movable shaft • Semi-unique lock mechanism

•Only alarm-capable lock available
