Sealed Urinalysis Test Piece With Retractable Test Paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine test papers for urinalysis are prone to moisture-related failures when not sealed properly, leading to inaccurate results and inconvenience in use, with potential contamination of surrounding objects.
Innovation Solution
A test piece for urinalysis featuring a housing with a movable support that seals test paper, allowing it to extend and retract, ensuring single-use sealing and convenient operation, and includes a transparent side wall to avoid light interference and improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If test paper is packaged in a bottle or box for multiple tests, then storage convenience is improved, but sealing effectiveness deteriorates leading to moisture exposure and inaccurate results
Solution Approach 1:
The patent divides the test paper into individual single-use units, each sealed in its own housing. This segmentation ensures that only one test paper is exposed at a time, preventing moisture contamination of unused test papers while maintaining storage convenience. Each test paper is independently packaged and can be used sequentially without compromising the sealing of subsequent test papers.
2Ease of operation
If test paper is taken out from the packaging during testing, then testing operation is simplified, but contamination of surrounding objects increases
Solution Approach 1:
The test paper is nested within a housing that extends from the toilet bowl. The housing protects the test paper during extension and retraction, preventing contamination of surrounding objects. The test paper remains enclosed within the housing structure throughout the testing process, eliminating the need to handle exposed test paper and thereby preventing contamination.
3Productivity
If test paper is soaked in urine and left outside, then testing is completed, but convenience and hygiene deteriorate due to contamination risk
Solution Approach 1:
The housing is designed to be dynamically extendable and retractable. After the test paper absorbs urine, the housing automatically or manually retracts, drawing the soaked test paper back into the protected environment. This dynamic movement eliminates the need for users to handle contaminated test paper, significantly improving convenience and hygiene while completing the testing process.

AI summary
Disclosed are a test piece for urinalysis, a transmission mechanism, and a toilet. The test piece for urinalysis comprises a housing, a support, and test paper. The support is movably arranged on the housing, and the test paper is placed on the support to move with the support relative to the housing. In an initial state, the test paper is sealed in the housing. During testing, the test paper is exposed out of the housing by driving the support. The test paper can be effectively sealed to ensure its effectiveness and the accuracy of test results, and the test piece for urinalysis is more convenient and hygienic to use.
