Portable Urine Analyzer Tray for Hygienic Strip Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable urine analysis devices lack a convenient and hygienic method for disposing of analyzed strips, leading to cumbersome disposal and potential hand contamination.
Innovation Solution
A portable urine analysis device with a modular, compact design featuring a tray that drops analyzed strips into an accommodation box for temporary storage, linked with an external electronic device for remote control and health information management, and a semi-automatic/automatic sheet system for hygiene and odor prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable urine analysis device is designed without a strip disposal mechanism, then the device structure remains simple and compact, but the user experiences cumbersome disposal and hand contamination
Solution Approach 1:
The device automatically drops analyzed strips into the accommodation box using a movable tray mechanism, eliminating the need for manual disposal by the user. The system serves itself by automatically handling the waste strips after analysis is complete.
Solution Approach 2:
The device is divided into functional modules including a main body, a movable tray for holding strips, and a separate accommodation box for waste strips. This segmentation allows the disposal function to be added without redesigning the entire device structure.
2Object-affected harmful factors
If analyzed strips are stored in an open accommodation box, then the device maintains a compact structure, but hygiene is compromised and bad odor occurs
Solution Approach 1:
A sheet is used to cover the accommodation box, creating a barrier that prevents odor escape and maintains hygiene. The sheet acts as a flexible barrier that can be easily implemented without adding rigid structural complexity.
Solution Approach 2:
The accommodation box is integrated within the main device body, and the sheet is nested within the accommodation box. This nested structure allows multiple functions (storage, coverage, hygiene protection) to be combined in a space-efficient manner.
3Ease of operation
If a movable tray structure is used to drop strips, then power consumption increases, but strip disposal convenience is improved
Solution Approach 1:
The movable tray operates periodically - moving to the dropped position only when needed to release analyzed strips, rather than continuously moving. This periodic operation reduces overall power consumption while maintaining disposal convenience.
Solution Approach 2:
The tray is designed to be movable rather than fixed, allowing it to dynamically change position between the loading position and the dropped position. This dynamic capability enables automatic strip disposal while consuming power only when position changes are required.

AI summary
Provided is a portable urine analysis device including: a main housing including: a tray including a tray driving unit in which a strip is loaded to introduce and withdraw the strip, wherein the strip that is completely analyzed is dropped via the tray and a urine analysis module analyzing urine of the strip to generate urine analysis information; a sub-housing coupled under the main housing and including an accommodation box which is slidable while the accommodation box has a space that temporarily stores the dropped strip; a support supporting the sub-housing. According to the portable urine analysis device of the present invention, urine is analyzed by using a strip as a medium, portability is reinforced with a compact and slim structure, and a completely analyzed strip is disposed of hygienically.
