Here at AJProtech we want more than just making a product work: we put ourselves into the user’s shoes to
see how we can make it in the most convenient and reliable way, considering all possible applications and
For this product, our design approach was based on three pillars: reliability, security, and convenience. We
wanted to provide the user as much control as possible over the MoKoo, while preventing any malfunction due to
power limitation, environmental conditions, or malicious attacks.
The first big issue is the power consumption, that is, how to put enough energy into such a small device. We
addressed this issue by using Bluetooth low power (BLE) module and a low consumption motor system, which can
operate over a year with only 2 CR2032 lithium batteries. To ensure proper operation under any condition
we designed a device that can operate with temperatures from -23°C to 65°C, with a waterproof (IP66)
To achieve the security pillar, we designed a communication system with bank-grade encryption, to prevent any
malicious access to the device from third parties, and to ensure reliable communication and data transfer from
actual user. Padlock uses metal allow enclosure that can withstand brutal mechanical force and numerous break in
Finally, we addressed the convenience pillar by adding several features to the lock and the app, including
unlocking by proximity, unlocking by manual code (if the smartphone is not easily accessible), access sharing
between users, access tracking, and battery monitoring. Moreover, we designed the battery changing process to be
as simple as possible, without any screws or complicated sequences.
