Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing sample liquids, such as blood or saliva, are complex and time-consuming due to the need for separate steps of sample collection, dilution, and analysis, requiring additional equipment and handling.
Innovation Solution
A portable sampling means with an integrated reservoir for dilution liquid that allows simultaneous or sequential delivery of the sample and dilution liquid using a manually actuated pump, eliminating the need for separate containers and intermediate mixing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate containers and intermediate mixing steps are used for sample collection and dilution, then the testing process is more thorough, but the complexity of the device and the time required increase
Solution Approach 1:
The patent combines the sample collection function and dilution liquid storage function into a single integrated sampling device. The sampling device includes both a sample collection chamber and a dilution liquid reservoir, eliminating the need for separate containers and intermediate transfer steps. This merging reduces device complexity while maintaining the thoroughness of the testing process through integrated washing and dilution functions.
Solution Approach 2:
The sampling device is designed with multi-functionality, serving as both a sample collector and a dilution station. The device can perform sample collection, dilution liquid delivery, washing, and mixing operations within a single integrated system, reducing the number of separate equipment pieces needed while ensuring comprehensive sample preparation.
2Manufacturing precision
If separate containers and intermediate mixing steps are used for sample collection and dilution, then the dilution process is more controlled, but the time required for testing increases
Solution Approach 1:
The dilution liquid is pre-loaded into the integrated reservoir of the sampling device before sample collection. This preliminary preparation eliminates the need for intermediate mixing steps and separate dilution operations, allowing immediate dilution upon sample collection. The device maintains precise dilution control through the pre-positioned dilution liquid while significantly reducing the time required for the testing process.
3Ease of operation
If an integrated reservoir for dilution liquid is incorporated into the sampling device, then the ease of operation improves, but the volume of the device increases
Solution Approach 1:
The dilution liquid reservoir is integrated into the sampling device structure, with the reservoir positioned to nest within or alongside the sample collection chamber. This nested arrangement allows the device to perform multiple functions (sample collection, dilution storage, washing) within a compact form factor, improving ease of operation while minimizing the increase in overall device volume.

AI summary
A sampling device and a system for testing of sample liquid are proposed. Very simple and prompt testing of the sample liquid is enabled in that the sampling device has a reservoir for the dilution liquid and that the taken-up sample liquid can be delivered by the dilution liquid directly to the testing area.
