Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample containers for quick tests require significant amounts of liquid and are not easily secure against tampering, while also lacking simplicity in handling and production effort.
Innovation Solution
A sample container with a cup-shaped, conical design made from transparent plastic, featuring a display carrier with integrated test strips and a temperature measuring strip, allowing for minimal liquid usage and secure integration of test elements, including a closure cap for easy pouring and archiving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cup-shaped display carrier is used to fill the sample container, then the liquid can be distributed to test strips, but the container requires significant amounts of liquid and is not secure against tampering
Solution Approach 1:
The display carrier is integrated directly into the bottom of the sample container, merging two previously separate components (container and display carrier) into a single unified structure. This eliminates the need for additional sample cups and reduces the total liquid volume required, while the integrated design inherently prevents tampering by making the system sealed and unified
Solution Approach 2:
The sample container bottom serves multiple functions: it acts as both the container base and the display carrier mounting surface. The display carrier is designed to perform both liquid distribution and test strip support functions simultaneously, reducing the need for separate components and minimizing liquid volume requirements
2Reliability
If test strips are fastened in the sample container by additional strip holders, then the display means can be secured, but the device complexity and production effort increase
Solution Approach 1:
The strip holders are integrated directly into the display carrier structure, merging the test strip support function with the existing display carrier. This eliminates the need for separate additional components while maintaining secure test strip positioning, thereby reducing device complexity and production effort
Solution Approach 2:
The strip holders are pre-formed as part of the display carrier during manufacturing, rather than being added as separate components during assembly. This preliminary integration simplifies the overall device structure and reduces the number of assembly steps required
3Ease of operation
If a mandrel is used to perforate the bottom of the sample cup, then the liquid can flow to the display means, but the production effort and device complexity increase
Solution Approach 1:
The mandrel function is integrated into the display carrier assembly process, where the display carrier itself is used to create the flow path during its attachment to the container bottom. This eliminates the need for a separate mandrel component and simplifies manufacturing by combining multiple functions into a single assembly operation
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
Enables quick, secure, and efficient testing with minimal liquid usage, ensuring high security against tampering and easy handling, while allowing for accurate measurement of liquid properties like temperature and substance presence.
Implementation Method 1
a pocket-shaped receptacle 14 for a scale-like temperature measuring strip is provided through a double-wall area of the peripheral wall 12 of the display carrier 10, so that the temperature of the liquid to be tested that is filled into the sample container 1 can be seen
Implementation Method 2
Changes in the color of test fields provided on the test strip then give an indication of specific substances contained in the liquid

AI summary
The sample container (1) has a display portion (16) that is configured for property of the fluid. The portion of the sample container is formed of a transparent material. The display portion is mounted and enclosed with an indicator carrier (10), so that the display portion is visible through a wall region of the sample container. The display portion is extended along the peripheral wall along a wall portion of the sample container. A display portion is provided with test zones (15).
