Detecting Apparatus Buffer Solution Storage and Release Mechanism
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, leading to operational complexities and potential bacterial contamination.
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, while preventing air exposure and bacterial growth, and includes a sample collector with a hollow tube to manage air pressure and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buffer solution is stored separately from the detecting apparatus to avoid bacterial contamination, then the reliability of the buffer solution is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent integrates the buffer solution storage chamber directly into the detecting apparatus body, merging the previously separate storage and detection components. This allows the buffer solution to be readily available during detection without requiring separate storage containers and manual transfer operations, thereby simplifying the overall operation while maintaining solution quality through sealed storage.
Solution Approach 2:
The buffer solution is pre-stored in a sealed chamber within the detecting apparatus before detection is needed. The sharp-pointed portion is pre-positioned to pierce the storage chamber seal at the appropriate moment, enabling preliminary preparation of the buffer solution storage system while ensuring it is activated only when needed for detection.
2Ease of operation
If the buffer solution is added to the detecting apparatus directly, then the ease of operation is improved, but the reliability deteriorates due to bacterial contamination
Solution Approach 1:
The patent employs a flexible sealing membrane to close the buffer solution storage chamber. This thin film allows the storage chamber to be sealed against bacterial contamination while still enabling controlled release of the buffer solution through the sharp-pointed portion when detection is required, thus maintaining both reliability and ease of operation.
3Reliability
If the storage chamber is sealed to prevent air exposure, then the reliability is improved, but the ease of operation worsens due to difficulty in accessing the buffer solution
Solution Approach 1:
The patent extracts a portion of the sealing membrane from the storage chamber closure to create a controlled opening. This extracted membrane section allows the sharp-pointed portion to access and release the buffer solution when needed, while the remaining sealed membrane maintains protection against air exposure and bacterial contamination, thus balancing reliability with operational accessibility.

AI summary
A detecting apparatus includes a storage chamber containing a treating fluid. The detecting apparatus is internally provided with a sharp-pointed portion. The storage chamber makes a movement relative to the sharp-pointed portion and will be pierced by the sharp-pointed portion during the moving process. The detecting apparatus further includes a collecting chamber. The released treating fluid may flow into the collecting chamber which is disposed inside a first shell and used to contain a sample. An opening is disposed at an upper position of the first shell. The collecting chamber is internally provided with a testing element for detecting an analyte. The testing element is disposed on a carrier which has a specific matching form with the collecting chamber. A buffer solution is disposed in an independent chamber of the detecting apparatus. The carrier has a specific matching form with the collecting chamber in the first shell.
