Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rapid diagnosis apparatuses for detecting analytes in samples, such as urine and saliva, require complex handling of buffer solutions to maintain pH stability, which can lead to bacterial growth and inaccurate results due to exposure to air.
Innovation Solution
A detecting apparatus with a storage chamber containing a buffer solution and a sharp-pointed portion that releases the solution into a collecting chamber, where it can be used for sample detection, along with a sample collector that prevents leakage and enhances sample extraction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buffer solution is stored separately from the detecting apparatus to avoid bacterial growth, then the reliability of detection is improved, but the device complexity and ease of operation deteriorate due to additional steps required to add buffer solution during detection
Solution Approach 1:
The detecting apparatus is divided into functionally independent modules: a buffer solution storage chamber that can be separately replaced, and a sample collection chamber. This segmentation allows the buffer solution to be pre-stored in a sealed environment (maintaining reliability) while being easily accessed during detection without complex operations (reducing operation complexity).
Solution Approach 2:
The buffer solution is prepared and stored in advance in the storage chamber before the actual detection process. This preliminary action eliminates the need for on-site buffer solution preparation or complex handling during detection, simplifying the overall operation while maintaining detection accuracy through pre-equilibrated buffer conditions.
2Ease of operation
If the buffer solution is exposed to air at room temperature for a long time to maintain availability, then the ease of operation is improved, but the reliability deteriorates due to bacterial growth and pH change
Solution Approach 1:
The storage chamber is designed with sealed flexible membranes or thin film structures that enclose the buffer solution. These flexible sealing structures maintain the buffer solution in a closed, sterile environment (preventing bacterial growth and pH change) while allowing easy access and exchange of the buffer solution when needed, thus simultaneously achieving reliability and ease of operation.
3Ease of operation
If the storage chamber is designed to be easily replaceable to simplify operation, then the ease of operation is improved, but the manufacturing precision and structural integrity may deteriorate
Solution Approach 1:
The storage chamber is designed with dynamic connection features that allow it to be easily attached and detached during operation. This dynamic design incorporates standardized connection interfaces and flexible sealing mechanisms that ensure reliable connection (maintaining manufacturing precision) while enabling simple user replacement (improving ease of operation).
