LOTIK

LOTIK smart water management system is a LoRa wireless network of sensors installed at the point of water use to detect leaks. The one-handed clamp mechanism allows convenient installation on the outside of any pipe from 1/4” up to 1 1/2” diameter, discreetly under the sink or on larger fixtures. Cloud implemented AI accurately determines the location and amount of water usage throughout a multi-tenant building, saving landlords money. I managed this project for Pensa and LOTIK, from design research to proof of concept, through detailed mechanical engineering, electrical engineering (performed by Volta Labs), testing and release for manufacturing.

Process

Above: Design process renderings of early concepts. Version 2 has functioning PCBs and barebones 3d printed housings. Version 3 shows some of our industrial design candidates during early development phases of the project. Below: Hardware validation. Varying the sensor pressure in a benchtop test fixture, Multijet Fusion 3d printed works-like prototype and section view showing the internals and rigid/flex PCB under development in Solidworks.

Above: Exploded view of pilot sensor assembly and draft analysis of lower jaw and housing components. The tamper-proof ratchet mechanism allows for one handed install in inconvenient locations and has a hidden release button. Below: Realtime monitoring on a superintendants dashboard and phone. Leaks and intermittantly running water fixtures are identified and reported for repair, preventing significant recurring costs for the landlord.
