Toilet Urine Test Module Channels to Prevent Cross-Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urine test devices suffer from mutual contamination of test elements, require frequent replacement, and have inconvenient and laborious disposal processes, leading to poor user experience and hygiene issues.
Innovation Solution
A test device with independent accommodating channels for separate test modules, a movable container body, and a driving mechanism to automate module replacement, along with a plugging element to seal the test hole, ensuring hygiene and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If test elements are uniformly fixed and placed in existing urine test devices, then the device structure is simple, but the test elements contaminate each other and require frequent replacement
Solution Approach 1:
The container body is divided into multiple independent accommodating channels (first accommodating channel, second accommodating channel, etc.), each channel holding a separate test module. This segmentation prevents contamination between test elements while maintaining a relatively simple overall structure.
Solution Approach 2:
Multiple test modules are nested within the single container body, with each test module positioned in its own accommodating channel. This nesting approach allows multiple separate test elements to be stored in one container without requiring multiple separate containers.
2Reliability
If test modules are stored in a container without independent channels, then the device volume is reduced, but the test modules cannot be securely held and may fall off
Solution Approach 1:
The container body is segmented into multiple independent accommodating channels, each providing secure retention for a single test module. This segmentation allows for compact volume while ensuring each test module is securely held in its designated channel.
3Ease of operation
If the container body is fixed and cannot be disassembled, then the structure is stable, but maintenance and replacement are inconvenient
Solution Approach 1:
The test assembly is segmented into detachable components: the container body and the rear cover are connected through a detachable connection structure. This allows the rear cover to be removed for maintenance or replacement while keeping the container body stable during operation.
Solution Approach 2:
The connection structure between the container body and rear cover transitions from a fixed state during operation to a detachable state for maintenance. The rear cover can be dynamically assembled and disassembled based on operational needs.

AI summary
Provided in the present invention are a test device, a toilet and a test method. The test device comprises a test module, and further comprises a container body used for storing the test module. The interior of the container body is provided with a plurality of mutually independent accommodating channels; the test module comprises a test element, and a liquid under test is tested by means of the test element; several test modules are provided and mounted in the accommodating channels respectively, and each test module can independently extend out of the corresponding accommodating channel. By mounting the test modules in the plurality of independent accommodating channels, the test modules are separated and used alone without contaminating each other, and the test device does not need to be replaced frequently and is convenient and hygienic to use.
