This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,129.

Summary of the Inventive Concept

An improved robotic floor cleaning device that optimizes liquid release based on device movement, surface type, and orientation, ensuring efficient and effective cleaning.

Background and Problem Solved

The original patent's controlled liquid releasing mechanism has limitations in adjusting to varying floor surfaces and device movements. The new inventive concept addresses these limitations by introducing adaptive liquid release, reducing waste and enhancing cleaning performance.

Detailed Description of the Inventive Concept

The enhanced robotic floor cleaning device features a motion sensor, control module, and adjustable rotatable cylinder. The motion sensor detects device movement, and the control module adjusts the liquid release rate in real-time. The rotatable cylinder's aperture size is dynamically adjusted based on the device's movement, ensuring optimal liquid release. Additionally, sensors detect surface type and orientation, further optimizing the cleaning process.

Novelty and Inventive Step

The new inventive concept introduces adaptive liquid release, which is not present in the original patent. The combination of motion sensing, real-time adjustment, and adjustable aperture size provides a novel and non-obvious solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include using different types of sensors, such as infrared or ultrasonic sensors, or incorporating machine learning algorithms to predict optimal liquid release rates based on device movement and surface type.

Potential Commercial Applications and Market

The enhanced robotic floor cleaning device has significant commercial potential in the cleaning services and consumer electronics industries, offering a more efficient and effective cleaning solution for various floor surfaces.
