Urine Test Device With Multi-Strip Tray and Optical Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine test devices are inconvenient for users as they require multiple test strips for comprehensive analysis, leading to repeated testing and cumbersome handling due to increased length and number of test items.
Innovation Solution
A urine test device with a strip tray system that allows multiple test strips to be seated and moved simultaneously, featuring a sensing module with LEDs and image sensors for color detection, enabling efficient analysis of multiple components in a single test.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ten or more kinds of test papers are disposed on the urine test strip to increase the number of test target components, then the number of analysis items is increased, but the length of the urine test strip is increased making it inconvenient for users
Solution Approach 1:
The patent combines multiple test strips (first test strip with first test paper and second test strip with second test paper) into a single holder that can be processed simultaneously by one device. This merging approach allows multiple analysis items to be tested without requiring each individual strip to be long, thus maintaining user convenience while increasing the number of analysis items.
2Adaptability or versatility
If two or more urine test strips are used to test many test target components, then the number of test target components is increased, but the device complexity and操作流程 are increased requiring repeated testing
Solution Approach 1:
The patent creates a universal holder that can accommodate multiple different types of test strips simultaneously. The holder is designed with multiple seating parts that can hold first test strips, second test strips, and potentially other test strips, allowing a single device to perform multiple testing functions that previously required separate devices and repeated操作流程.
3Adaptability or versatility
If two or more urine test strips are tested per one inspectee, then comprehensive analysis is achieved, but the time required for testing is increased due to repeated testing
Solution Approach 1:
The patent enables continuous processing of multiple test strips simultaneously. The holder allows multiple strips to be inserted at once, and the device can process all strips in a single continuous operation rather than requiring sequential processing. This eliminates the time loss associated with repeated insertion and processing of individual strips while maintaining comprehensive analysis capability.
