Broad automatic shutoff was not the moat.
What changed: Prior-art review weakened the original automatic-funnel novelty thesis, so the problem was reframed around managing normal human reaction delay and temporary excess-fuel capture.
We show enough for customers and manufacturers to understand the problem, product outcome and current stage without publishing sensitive mechanisms before the appropriate IP or confidentiality gate.

Designed around staging passive work bins where jobs happen, then using one compact carrier for pickup, transport, dump and drop-off.

Low-speed property ventilation focused on useful airflow, lower noise, durable serviceable components and partner-fit hardware.

An animal-and-equipment wash platform built around cleaning, organization, restraint points, warm-air drying and serviceability.

Large-format outdoor entertainment designed around visibility, audio, usability and realistic daylight performance.

Tracked electric property-work platform focused on supervised autonomy, serviceable hardware and practical property jobs.

A modular outdoor family-room platform designed around real comfort, easy setup, durability and manufacturer fit.
These examples are intentionally non-confidential. They show how WTF challenges its own assumptions instead of treating every feature list as an invention.
What changed: Prior-art review weakened the original automatic-funnel novelty thesis, so the problem was reframed around managing normal human reaction delay and temporary excess-fuel capture.
What changed: Crowded prior art pushed development away from feature-count thinking and toward load behavior, access, seating comfort, structural packaging and mechanisms that still need physical proof.
What changed: The architecture shifted toward established EC motor/impeller technology and concentrated development on airflow path, shrouding, vibration isolation, mounting, low-speed use and serviceability.
