This system manages water purification units across many locations by tracking the individual usage of their internal parts. When a unit nears its operational limit, a refurbished replacement is sent out. The old unit is then repaired by replacing only the components that have insufficient life remaining for future use, such as specific de-ionisers, an ultraviolet unit, or a pump.
Why it matters: Filed before widespread IoT sensors and cloud-based predictive maintenance platforms were common. Today's robust data analytics and connectivity make tracking individual component usage and managing distributed refurbishment logistics far more feasible and cost-effective.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
