Solution Overview
Problem
Existing metering devices face challenges in maintaining effective operation over a long service life, particularly in ensuring proper metering processes and cleaning of components without additional separate devices for water supply.
Innovation Solution
Incorporating a switching device that allows the spray nozzle to operate in two modes: a spraying mode for dissolving mediums and a rinsing mode for providing pure water, which can be used for cleaning and calibration purposes, without the need for additional separate metering devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single spray nozzle is used for both medium dissolution and cleaning, then device complexity is reduced, but the reliability of metering processes deteriorates due to chemical residue buildup
Solution Approach 1:
The spray nozzle is designed with switchable operating modes (spraying mode and rinsing mode) that dynamically change its function. The nozzle can switch between dissolving medium with water and rinsing without medium, allowing it to adapt to different operational requirements and maintain reliability while avoiding chemical residue buildup
Solution Approach 2:
The single spray nozzle is designed to perform multiple functions: it can operate in spraying mode to dissolve medium and in rinsing mode to clean components. This multi-functionality eliminates the need for separate nozzles for each purpose, reducing device complexity while maintaining reliability through proper cleaning cycles
2Productivity
If the spray nozzle operates continuously in spraying mode, then productivity is maintained, but the duration of action deteriorates due to chemical residue buildup and component degradation
Solution Approach 1:
The system implements periodic rinsing cycles where the spray nozzle alternates between spraying mode (for productivity) and rinsing mode (for cleaning). This periodic action removes chemical residues at regular intervals, preventing degradation and extending the service life of the metering device while maintaining overall productivity
3Reliability
If separate metering devices are added for water supply and cleaning, then reliability is improved, but device complexity increases
Solution Approach 1:
The spray nozzle is designed as a universal component that can perform both medium dissolution and cleaning functions by switching between operating modes. This eliminates the need for separate metering devices for water supply and cleaning, reducing device complexity while maintaining reliability through proper functional separation during different operational phases
Solution Approach 2:
The system merges the functions of medium dissolution and cleaning into a single spray nozzle and water supply system. By combining these functions while maintaining the ability to operate in distinct modes, the invention reduces the number of components needed while ensuring reliable operation for both purposes

Function Achieved in This Case
This solution enables efficient and prolonged operation of metering devices by allowing for regular rinsing and the provision of pure water, reducing chemical residue buildup and extending the device's lifespan.
Implementation Method 1
The spray nozzle is connected to a water line and can dispense water in order to dissolve the medium in the container
Implementation Method 2
a switching device which can be activated by the controller and which has at least two different switching states for operating the spray nozzle in different operating modes

AI summary
A metering device for metering powdery or solid-like media such as detergents or disinfectants and for supplying the media in a dissolved state to a washing or cleaning system, including a support, in particular a cartridge support, to which a container, in particular a cartridge, with a powdery or solid-like medium can be attached. The support or the container includes a grid which prevents the medium from exiting the container. A spray nozzle controlled by a controller of the metering device dispenses water for solvating the medium. The medium dissolved in water and passing through the grid can be supplied to the washing or cleaning system via a supply device. The metering device also has a switching device that can be activated by the controller and has at least two different switching states for operating the spray nozzle in different operating modes.
