Innovation Solution
A urine detection method and device that selects urine samples of a preset volume, mixes them with a preset detection object capable of reacting with the component to be detected, measures micro current values over a set time, and compares these values to a pre-established relationship table to determine component content, allowing for direct analysis without medical expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional urine detection devices use complex analysis methods requiring medical knowledge, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent divides the urine detection process into separate functional modules: a detection object module containing reagents, a sample addition module, a detection module with electrodes, and a processing module. Each module performs a specific function, allowing the complex analysis to be segmented into simple user actions (adding sample) and automated processing steps, thus maintaining precision while improving ease of operation
Solution Approach 2:
The patent introduces a detection object as an intermediary that contains pre-configured reagents and detection mechanisms. This intermediary handles the complex chemical reactions and signal processing, allowing users to simply add urine samples without needing to understand the underlying medical analysis processes, thereby resolving the contradiction between measurement precision and ease of operation
2Reliability
If conventional urine analyzers require professional medical knowledge for operation, then reliability of results is improved, but device complexity increases
Solution Approach 1:
The detection object is designed to perform self-service functions by automatically mixing reagents with urine samples, conducting chemical reactions, and generating detectable signals. The device autonomously completes the complex analysis procedures that previously required medical expertise, maintaining result reliability while reducing operational complexity to simple sample addition and result reading
Solution Approach 2:
The detection object contains reagents and detection mechanisms that are pre-configured and prepared in advance. The complex analytical procedures are pre-programmed into the device, so users only need to add samples without needing to understand or perform the complex preparation and analysis steps, thus maintaining reliability while reducing operational complexity

AI summary
A urine detection method and a urine detection device are disclosed. Based on types of components to be detected in urine, an equal number of urine samples of a preset volume as the types of components to be detected are selected, wherein each urine sample is used for detecting one component; for each urine sample, based on a component to be detected, the urine sample is mixed with a preset detection object of a fixed mass that can react with the component to be detected in the urine; one or more micro current values of a mixture of the urine sample and the preset detection object within a preset time period are detected; a micro current average value based on the one or more micro current values within the preset time period is calculated; the micro current average value is compared with a pre-established corresponding relationship table of contents of a preset component content and the micro current average values, so as to determine content of the component to be detected in the urine, wherein the preset component is same as the component to be detected.
