On-site Excrement Analysis Device with Segmented Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing excrement, such as urine and stool samples, require samples to be transported to a laboratory, leading to cumbersome and time-consuming processes, which hinder continuous preventive examinations due to the effort involved and the risk of contamination affecting analysis results.
Innovation Solution
A device with a guide part divided into contamination and clean areas, featuring a movable arm element that can axially displace to take new samples while preventing cross-contamination, equipped with sensors for on-site analysis and a sample carrier with multiple analysis fields for efficient and reliable analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If samples are transported to a laboratory for analysis, then analysis can be performed with standard equipment, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The analysis function is extracted from the centralized laboratory and brought to the point of sample collection through portable analysis devices. The patent describes devices that can perform analysis directly at the collection site, eliminating the need for physical transport of samples to a laboratory while maintaining analysis capability.
Solution Approach 2:
Portable analysis devices serve as intermediaries between the sample collection point and the centralized laboratory. These devices enable on-site analysis when laboratory equipment is unavailable, and can also prepare samples for subsequent centralized analysis, acting as a bridge between field and lab environments.
2Measurement precision
If samples are transported to a laboratory, then comprehensive analysis can be performed, but the risk of contamination during transport increases
Solution Approach 1:
The analysis function is extracted from the centralized laboratory and brought to the point of sample collection through portable analysis devices. The patent describes devices that can perform analysis directly at the collection site, eliminating the need for physical transport of samples to a laboratory while maintaining analysis capability.
Solution Approach 2:
Analysis is performed preliminarily at the collection site before transport, or samples are prepared in a controlled manner for subsequent transport. The patent describes on-site analysis capabilities that allow immediate examination, preventing contamination that might occur during transport and storage.
3Productivity
If a movable arm element is used to take new samples, then sampling efficiency improves, but the risk of cross-contamination from previous samples increases
Solution Approach 1:
The guide part is segmented into distinct contamination area and clean area zones. The patent describes a guide structure with separated regions where the movable arm element operates in the contamination area during sampling and is then transferred to the clean area for the next sampling operation, preventing cross-contamination between samples.
Solution Approach 2:
The guide part acts as an intermediary transfer mechanism between the contamination area and clean area. The patent describes how the guide structure facilitates controlled transfer of the movable arm element and sample carriers between zones with different contamination levels, maintaining sampling efficiency while preventing cross-contamination.

AI summary
The invention relates to a device for the on-site analysis of excrement, comprising a housing, a removal device, by means of which a sample of excrement can be removed. The removal device comprises an arm element for a sample carrier, which is movable relative to the housing in the axial direction, said arm element being guided at least partially in a guide part in such a way that it can be retracted and extended, also comprising a charging device which supports a new sample carrier for the removal device, and an analysis device which at least partially analyses the sample. The device is characterised in that the guide part comprises a contamination region having a guide path for guiding the moveable arm element and also a clean region, in which a new sample carrier can be arranged at least partially next to the guide path.
