Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing systems for solid treatment agents in commercial cleaning processes face challenges in maintaining consistent concentrations and stability, particularly when the concentration falls below a certain level or fluctuates, leading to inefficiencies and microbiological instability.
Innovation Solution
A dosing device that uses a float-controlled system to circulate and spray a solid treatment agent with a fluid, allowing for adjustable concentration settings between 3% and 45% by varying the filling quantity of the float, which actuates a pump when a desired density is reached, ensuring continuous adjustment and storage of the treatment agent solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor electronics are used to generate treatment agent concentration in real-time, then the system operates accurately only at low concentrations (0.5-10 g/l), but cannot maintain stability at higher concentrations
Solution Approach 1:
The treatment agent solution is prepared in advance at the desired concentration (3-45% w/v range) and stored in a storage container, rather than being generated in real-time. This preliminary preparation allows for stable, concentrated solutions to be created under controlled conditions, then dosed as needed without microbiological degradation during storage.
2Manufacturing precision
If solid treatment agent is dissolved in a defined quantity of fluid in a single dissolving process, then complete dissolution is achieved, but the system lacks flexibility for concentration adjustment
Solution Approach 1:
The system uses a storage container that can hold concentrated treatment agent solutions at various concentration levels (3-45% w/v). A dosing device then dynamically adjusts the concentration delivered to the cleaning machine by controlling the dosing rate, allowing flexible adaptation to different cleaning requirements while maintaining complete dissolution of the solid agent.
3Productivity
If treatment agent concentration fluctuates or falls below a certain level, then dosing efficiency decreases, but continuous monitoring increases system complexity
Solution Approach 1:
The system incorporates a sensor that continuously monitors the concentration of treatment agent in the storage container and provides feedback to a control unit. The control unit adjusts the dosing rate accordingly to maintain optimal concentration levels, ensuring consistent dosing efficiency without requiring complex manual monitoring systems.
4Productivity
If liquid treatment agents are used in multi-dosing systems, then cost-effective and reliable dosing is achieved, but maintenance requirements increase
Solution Approach 1:
The system changes the physical state of the treatment agent from liquid to solid form, which can be stored in concentrated form without microbiological degradation. This allows for longer storage periods and reduced maintenance frequency, as solid treatment agents do not require the same level of monitoring and replenishment as liquid agents, while still enabling cost-effective dosing through the storage and controlled dissolution system.

AI summary
The invention relates to a metering device (10) for dissolving a solids treatment agent (50) with a dissolving/storage container (40) in which a fluid is stored. The fluid flows in via a water inlet (41) and is circulated by a pump (45, 68). This pump acts on a line (46) through which the solids treatment agent (50) is directed to a spray nozzle (47), from which it exits and dissolves the solids treatment agent (50). The pump (45, 68) is controlled by a hollow float (20) or a solid float (31), which rises or falls depending on the concentration of the dissolved solids treatment agent (50) in the treatment agent/fluid mixture (48) in the dissolving/storage container (40).
