Solution Overview
Problem
Existing sprayer devices have a complex design with multiple parts, leading to increased potential leak points and complexity in assembly and operation.
Innovation Solution
A one-piece, integrally molded valve body with a simplified design that includes a base portion, pumping chamber, inlet and outlet ducts, and a flow-through filling passage, reducing the number of parts and potential leak points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional multi-part valve body design is used, then the sprayer device can be assembled with separate components, but the number of parts increases leading to more potential leak points and assembly complexity
Solution Approach 1:
The patent merges multiple separate components (valve body, filling passage, pumping chamber, inlet duct, outlet duct) into a single integrally molded one-piece valve body assembly, eliminating the need for separate parts and their associated connections, thereby reducing the number of parts and potential leak points while maintaining manufacturing feasibility
Solution Approach 2:
The one-piece valve body assembly performs multiple functions simultaneously: it serves as the structural valve body, contains the pumping chamber, provides the filling passage, and includes integrated inlet and outlet ducts, thereby reducing device complexity while maintaining ease of manufacture through a universal component
2Ease of manufacture
If a traditional multi-part valve body design is used, then each component can be manufactured separately, but the number of connection points increases leading to more potential leak points
Solution Approach 1:
The patent combines multiple separate components into a single integrally molded valve body assembly, eliminating the connections between parts that would otherwise serve as potential leak points, thereby improving reliability while maintaining ease of manufacturing through integral molding
3Adaptability or versatility
If a complex multi-part design is used, then more functional features can be added, but the assembly and operation become more complex
Solution Approach 1:
The patent integrates multiple functional features (filling passage, pumping chamber, inlet duct, outlet duct) into a single one-piece valve body assembly, maintaining adaptability and versatility while simplifying operation by reducing the number of components and connections the user must manage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the sprayer device design, reduces the number of parts and potential leak points, and enhances functionality by allowing for easier filling and operation.
Implementation Method 1
a spring captured between said trigger lever and said valve body
Implementation Method 2
Within the pump chamber there is a suction and delivery valve adapted to allow the liquid to be sucked in a one-way direction from the container up through the dip tube to the pump chamber and to deliver the liquid from the pump chamber to the delivery nozzle
Implementation Method 3
a pump operated by the trigger lever to suction liquid from the container and to spray it through the nozzle

AI summary
A sprayer device with a trigger operated pump is operative for pumping and spraying liquid from an attached liquid container. The sprayer device includes an integrally molded valve body provided with a base portion that is configured to be mounted to the neck of the liquid container and a delivery nozzle from which the liquid is sprayed. A pumping chamber in the valve body is in fluid communication with an inside of the fluid container and is further in fluid communication with the delivery nozzle. The valve body is further provided with a head portion that has a filling passage extending between the head portion and the base portion such that a liquid received in the head portion flows through the valve body, around the pumping chamber and exits the base portion into the mounted liquid container.
