Solution Overview
Problem
Existing dosing devices face challenges in maintaining effective dosing processes over a long service life, particularly in ensuring proper operation and cleaning of components without additional separate dispensing devices.
Innovation Solution
Incorporating a switching device that allows the spray nozzle to operate in two modes: a spraying mode for dissolving medium and a rinsing mode for flushing, using the same water supply without dissolving the medium, enabling the use of pure water for cleaning and calibration purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate dispensing device is added for flushing operations, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The spray nozzle is designed to perform multiple functions: dissolving medium (spraying mode) and flushing/cleaning (rinsing mode). The switching device enables the same spray nozzle to operate in two different modes by controlling water flow direction, eliminating the need for a separate dispensing device while maintaining cleaning effectiveness
Solution Approach 2:
The patent combines the dissolving function and flushing function into a single integrated system. The spray nozzle serves both purposes, and the switching device merges the control of both operations into one component, reducing overall system complexity while ensuring proper cleaning
2Productivity
If the spray nozzle operates continuously in spraying mode, then medium dissolution is maintained, but chemical residue buildup occurs
Solution Approach 1:
The system implements periodic switching between spraying mode and rinsing mode. The control unit automatically alternates between dissolving medium and flushing the spray nozzle, preventing chemical residue buildup while maintaining continuous dosing capability. This periodic action ensures the spray nozzle remains clean without interrupting overall productivity
Solution Approach 2:
The rinsing mode provides continuous cleaning action to prevent residue buildup. By automatically switching to rinsing mode at appropriate intervals, the system maintains continuous useful action - both medium dissolution and nozzle cleaning - ensuring the spray nozzle remains free of chemical residues while dosing continues
3Reliability
If water pressure is increased for better flushing, then cleaning effectiveness is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts water pressure based on operational mode. During rinsing mode, the switching device directs water flow to provide adequate flushing pressure when needed. During spraying mode, normal operating pressure is maintained. This dynamic adjustment ensures effective cleaning only when necessary, reducing overall energy consumption while maintaining cleaning effectiveness
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
This solution ensures prolonged device functionality by allowing for regular and efficient flushing and cleaning operations, maintaining the dosing device's performance and preventing chemical residue buildup without the need for additional dispensing devices.
Implementation Method 1
The water is released from the spray nozzle under a certain pressure
Implementation Method 2
The water is released from the spray nozzle under a certain pressure and directed vertically upward or diagonally upward
Implementation Method 3
The grid prevents the medium in its original state, i.e., in undissolved form, from passing through the grid
Implementation Method 4
When water hits the grid, the water can dissolve or partially dissolve the medium
Implementation Method 5
The medium dissolved in water, i.e. the media solution, is collected, in particular by a collecting device and fed to the target device via a feeding device, i.e. via fluid lines, if necessary with the aid of a pump
