Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for collecting and testing liquid samples, such as fecal samples, are inconvenient and prone to sample deterioration during transportation, leading to inaccurate test results. Additionally, these devices often struggle with testing multiple analytes simultaneously and are not suitable for home or on-site use.
Innovation Solution
A device comprising a sample chamber, a detection chamber with a testing element, and a connecting chamber that allows for fluid communication between the sample and detection chambers. The device includes a sealing film and a piercing element to control fluid flow, enabling the liquid sample to flow into the detection chamber for testing when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If samples are collected and stored by special collection tools and then sent to professional institutions for testing, then testing accuracy can be maintained, but operation convenience deteriorates and transportation time increases causing sample deterioration
Solution Approach 1:
The patent combines the sample collection function and testing function into a single integrated device. The collection chamber stores the sample and the detection chamber with testing element performs analysis, eliminating the need to transport samples to external laboratories while maintaining testing accuracy through controlled conditions.
Solution Approach 2:
The device enables users to perform testing themselves without requiring professional laboratory facilities. The integrated system allows individuals to collect and test samples at home or on-site, making the testing service self-sufficient and eliminating transportation requirements.
2Reliability
If samples are sent to professional institutions for testing, then testing accuracy is maintained, but testing time increases due to transportation and processing delays
Solution Approach 1:
By merging collection and testing functions in one device, the patent eliminates the time-consuming transportation and external processing steps. Users can complete the entire testing process immediately after sample collection, significantly reducing total testing time while maintaining accuracy through controlled detection conditions.
3Adaptability or versatility
If conventional collection devices are used, then sample collection is possible, but fluid flow control to detection chamber is difficult and operation becomes complex
Solution Approach 1:
The patent introduces a connecting chamber as an intermediary between the collection chamber and detection chamber. This intermediate structure simplifies fluid flow control by providing a controlled transition zone, eliminating complex flow management requirements while maintaining versatile sample collection capabilities.

Function Achieved in This Case
The device allows for efficient and accurate testing of analytes in liquid samples, overcoming the limitations of existing devices by enabling step-by-step detection, reducing operation errors, and allowing for testing in various settings, including home and on-site use.
Implementation Method 1
a piercing element, wherein the piercing element is used for piercing the sealing film
Implementation Method 2
the level of the liquid in the sample chamber is higher than a bottom of the detection chamber... the liquid in the sample chamber flows from a high level of the liquid in the sample chamber to the detection chamber at a low level by virtue of gravity
