Solution Overview
Problem
Existing devices for distributing fluid into containers are complex and costly, requiring intricate control mechanisms to maintain a constant volume flow and adjust treatment time, and they lack a simple design.
Innovation Solution
A device comprising a rotor, fluid limiting element, and stator with fluid inlet and outlet openings, where the fluid limiting element moves between positions to control the treatment time and maintain a constant volume flow without the need for individual valve control, using a rotor and stator to define a chamber with alternating fluid connection regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex control mechanism with individual valve control is used to maintain constant volume flow and adjust treatment time, then the precision of fluid distribution is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple control functions into a single fluid limiting element that simultaneously maintains constant volume flow and controls treatment time. The element integrates the functions of flow regulation and timing control that would otherwise require separate valves and control mechanisms, thereby reducing device complexity while preserving manufacturing precision.
Solution Approach 2:
The fluid limiting element serves multiple functions: it acts as a flow restrictor to maintain constant volume flow, a timing mechanism to control treatment time through its angular position, and a distribution controller. This multi-functionality eliminates the need for individual valve control systems while achieving precise fluid distribution.
2Reliability
If multiple control mechanisms are used to adjust treatment time and maintain constant flow, then the reliability of fluid distribution is improved, but the number of parts increases
Solution Approach 1:
The patent merges the functions of flow control and timing adjustment into a single fluid limiting element. By combining these functions, the system maintains reliable fluid distribution through integrated control while reducing the number of parts compared to systems using separate valves and control mechanisms.
3Manufacturing precision
If individual valve control is used for each fluid outlet opening, then the precision of treatment time control is improved, but the ease of manufacture decreases
Solution Approach 1:
The fluid limiting element provides universal control for all fluid outlet openings simultaneously. By positioning the element at different angular orientations, the system controls treatment time for multiple outlets with a single component, achieving precise control while simplifying manufacturing compared to individual valve assemblies.
