Smart Locks are most commonly used by those who rent out their apartments (think AirBnB). Yet, battery-powered locks suffer a serious drawback: They sometimes fail, causing a lockout. Current backup solutions are totally inadequate. It is unreasonable to expect guests to arrive with batteries or USB cables or to haul batteries everywhere; even to the swimming pool, to ensure re-entry.
A lockout for a guest arrival is a serious problem; a lockout when retrieving luggage for departure, even worse. Reported Smart Lock problems include: unanticipated fast battery drain, battery leakage, inaccurate low-battery indicators, and human error: People forget to change batteries, and batteries die from inactivity.
In the understanding that hospitality businesses cannot afford even a single lock failure, Elliot Rais developed the Battery-Free Smart Lock to be feature-rich, eco-friendly, and failure-proof.
The challenge was how to update key codes remotely anytime 24/7, given that the lock is powered for only 15 seconds, and only when someone at the door activates the dynamo by pulling the lever. This patent successfully overcomes that challenge.
