Test Container Soiling Automation for Accurate Cleaning Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking the cleaning effect of cleaning devices in container treatment systems are prone to operator-induced contamination, leading to inaccurate results due to manual handling of test containers.
Innovation Solution
A device and method for mechanically introducing and applying a predetermined amount of soiling onto a test container, which is then automatically introduced into the container treatment system, minimizing operator contact and ensuring precise dosing and arrangement of contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of test containers is used to check cleaning effectiveness, then operator flexibility and simplicity are improved, but contamination accuracy deteriorates due to operator-induced contamination
Solution Approach 1:
The patent replaces manual mechanical handling of test containers with an automated mechanical introduction system. The device mechanically introduces test containers into the container treatment system without operator contact, eliminating operator-induced contamination while maintaining operational simplicity through automation.
Solution Approach 2:
The system enables self-service by having the container treatment system automatically process test containers without requiring operator intervention for contamination assessment. The mechanical introduction system feeds test containers automatically, and the system itself monitors cleaning effectiveness, reducing dependency on manual operations.
2Reliability
If mechanical introduction of test containers is used, then contamination prevention is improved, but device complexity increases
Solution Approach 1:
The mechanical introduction system serves multiple functions: it introduces test containers, prevents contamination, and integrates with the existing container treatment system. By making the introduction device multi-functional, the patent reduces the need for separate specialized equipment, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The patent merges the test container introduction function with the existing container treatment system. The mechanical introduction device is integrated into the system's workflow, combining functions rather than adding entirely separate equipment, which helps manage device complexity while maintaining contamination prevention.
3Measurement precision
If automated mechanical system is used for contamination application, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies parameter changes by precisely controlling the amount and distribution of contamination through the mechanical system. By adjusting parameters such as contamination quantity, placement position, and application method, the system achieves high measurement precision while the automated nature maintains operational simplicity through programmed sequences.

AI summary
The device comprises an insertion unit (213) for inserting or application of a predetermined amount of pollution into or on a testing container, and an infiltration unit for infiltration of the testing container in the container treatment plant. A determining unit is provided for determining the remaining amount of pollution after cleaning the testing container with the cleaning device. An independent claim is also included for a method for testing the cleaning efficiency of a cleaning device.
