Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for mixing aqueous solutions face challenges in achieving uniform dosing and mixing efficiency due to fluctuations in water quantity and quality, leading to inadequate disinfection or oxidation effects when producing chlorine dioxide, as they rely on manual stroke length adjustment and uneven temporal distribution of dosages.
Innovation Solution
The method involves using metering devices with integrated metering monitoring and stroke length control, where dosing devices with movable displacement elements and actuators adjust stroke length based on real-time measurement signals from sensors to ensure consistent and synchronized dosing of aqueous solutions, optimizing mixing and reaction product formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual stroke length adjustment is used in dosing devices, then device complexity is reduced, but manufacturing precision and dosing consistency deteriorate
Solution Approach 1:
The patent replaces manual mechanical stroke length adjustment with an automated actuator system that uses electrical control signals to precisely control the displacement element's position. This substitution of mechanical manual adjustment with an electromechanical control system resolves the contradiction by providing both automated precision and acceptable system complexity.
Solution Approach 2:
The patent implements a feedback mechanism where a dosing monitor detects the dosing stroke and provides measurement signals to a stroke length control. This closed-loop feedback system automatically adjusts the stroke length to maintain consistent dosing, resolving the precision issue while keeping the overall system complexity manageable through automated control.
2Device complexity
If stroke length is not adjusted dynamically, then device complexity is reduced, but adaptability to water quantity and quality fluctuations deteriorates
Solution Approach 1:
The patent makes the stroke length dynamic by enabling real-time adjustment through the actuator and stroke length control system. This allows the dosing device to adapt to fluctuations in water quantity and quality, resolving the adaptability issue while maintaining acceptable system complexity through automated control mechanisms.
Solution Approach 2:
The patent changes the operating parameter of stroke length dynamically based on process conditions. The stroke length control adjusts this parameter in response to dosing monitor signals, enabling the system to adapt to varying water conditions while managing complexity through parameter-based control rather than structural complexity.
3Device complexity
If dosing devices operate without integrated monitoring, then device complexity is reduced, but measurement precision and dosing accuracy deteriorate
Solution Approach 1:
The patent merges the dosing device with an integrated dosing monitor and stroke length control system. This combination of functions into an integrated unit provides precise measurement and control while managing overall system complexity through functional integration rather than separate independent systems.
