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. 11,856,942.

Background and Problem Solved

The original dual nozzle sprayer patent (Background) provided a fluid spray gun with multiple inlets and outlets, but it lacked the ability to provide simultaneous and customizable fluid spray patterns. The new invention addresses this limitation by introducing synchronized actuators and a programmable controller, allowing for a more efficient and adaptable fluid spray apparatus.

Novelty and Inventive Step

The new invention introduces the concept of synchronized actuators and a programmable controller, enabling simultaneous and customizable fluid spray patterns. This innovation provides a significant improvement over the original patent, offering enhanced efficiency, versatility, and adaptability in various fluid spray applications.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include different diverter structure designs, such as a rotary valve or a sliding gate valve. The programmable controller could be replaced with a manual adjustment mechanism or a wireless remote control. The invention could also be adapted for use with different types of fluids, such as paints or adhesives.

Potential Commercial Applications and Market

The enhanced dual nozzle sprayer has significant commercial potential in various industries, including agriculture, landscaping, and manufacturing. The invention's ability to provide customizable and simultaneous fluid spray patterns makes it an attractive solution for applications requiring precision and efficiency. Target markets may include farmers, landscapers, and manufacturers seeking to improve their fluid spray operations.
