Solution Overview
Problem
Existing lateral flow tests for analyte detection are cumbersome and prone to operator error due to the need for multiple components and steps, making them difficult to use in mobile or field settings without a clean environment.
Innovation Solution
A self-contained analyte detection apparatus with a mixing chamber, testing chamber, and scoop storage chamber, featuring a rotatable mixing valve and end cap with a collection scoop, allowing for compact, one-step sample collection, mixing, and testing within a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate components are used for sample collection and testing, then the testing function can be performed, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple separate components (collection device, mixing chamber, testing chamber) into a single integrated apparatus. The collection device can be inserted directly into the mixing chamber, which is then inserted into the testing chamber, creating a unified system that eliminates the need for separate handling of multiple components and reduces operator error.
Solution Approach 2:
The apparatus is designed to perform multiple functions within a single device: sample collection, sample mixing with delivery fluid, and analyte testing. The collection device serves both as a sampling tool and as a mechanism to introduce the sample into the mixing chamber, while the housing integrates storage, mixing, and testing functions.
2Productivity
If multiple separate components and steps are required, then the testing process can be completed, but the loss of time increases and productivity decreases
Solution Approach 1:
The delivery fluid is pre-loaded into the mixing chamber before the testing process begins. This preliminary preparation eliminates the need for separate steps of adding fluid during the test, allowing the sample to be mixed immediately upon insertion into the collection device and reducing the overall testing time.
Solution Approach 2:
The apparatus enables continuous operation where the collection device, mixing chamber, and testing chamber are sequentially connected and function in an uninterrupted sequence. The sample flows continuously from collection through mixing to testing without requiring the operator to pause or transfer the sample between separate devices.
3Ease of operation
If a compact self-contained environment is created, then ease of operation improves, but the volume of the device increases
Solution Approach 1:
The apparatus employs a nested structure where the collection device fits inside the mixing chamber, which in turn fits inside the testing chamber. The housing contains all three chambers along with the delivery fluid reservoir in a compact, space-efficient arrangement. This nesting minimizes the overall volume while maintaining the self-contained environment necessary for operation.

Data Source
AI summary
An analyte detection apparatus is disclosed and configured for testing a substance for the presence or absence of at least one target analyte. In at least one embodiment, a housing provides a mixing chamber and a testing chamber in selective fluid communication with the mixing chamber. During use of the apparatus, a volume of the substance is collected via a collection scoop and introduced into the mixing chamber where it is mixed with a delivery fluid within the mixing chamber. An end cap is engaged with the housing in order to seal the mixing chamber, and a mixing valve is moved into an open position, allowing the substance to travel into the testing chamber and come into contact with a test medium, with a resulting visual indication from the test medium being viewable via a result window.
