Pressure Accumulation Dispenser Piston Valve Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure-accumulation dispensers have complex structures and require additional components to achieve pressure-accumulation functions, making them cumbersome and difficult to assemble.
Innovation Solution
Incorporating a pressure-accumulation giving valve within the piston portion, featuring an insertion valve seat, a piston valve, a spring body, and a piston cover, which are integrally molded and press-fitted to reduce the number of components and simplify the structure, while preventing rust and ensuring easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure-accumulation dispenser uses conventional separate components for pressure accumulation, then the pressure accumulation function is achieved, but the structure becomes complex and the number of components increases
Solution Approach 1:
The patent combines the pressure accumulation function directly into the piston portion by integrating a valve mechanism within the piston body. The piston portion now serves dual purposes: moving the piston to pressurize liquid and housing the valve that controls pressure accumulation. This merging eliminates the need for separate pressure accumulation components, thereby achieving the pressure function while reducing structural complexity.
Solution Approach 2:
The piston portion is designed to perform multiple functions simultaneously: it acts as both the moving element for pressurization and as a housing for the pressure control valve. The valve mechanism within the piston portion controls both the intake and discharge of liquid, making the piston portion a multi-functional component that eliminates the need for separate dedicated pressure accumulation components.
2Reliability
If separate pressure accumulation components are used, then pressure function is achieved, but the number of components and assembly complexity increases
Solution Approach 1:
The valve mechanism is integrated directly into the piston portion, combining what were previously separate components (valve and piston) into a single unified structure. This integration reduces the total number of components that need to be manufactured and assembled, thereby improving ease of manufacture and assembly while maintaining the pressure control function.
3Reliability
If conventional pressure accumulation mechanisms are used, then pressure function is achieved, but the dispenser size increases
Solution Approach 1:
The valve mechanism is nested within the piston portion, with the valve body and components housed inside the piston structure. This nesting arrangement allows the pressure accumulation function to be achieved without adding external components, thereby maintaining a compact dispenser size while preserving the pressure accumulation capability.
