Solution Overview

Problem

Existing feces sampling containers face challenges in maintaining a consistent sampling amount and ensuring hygienic, easy confirmation of feces collection, particularly due to variations in feces characteristics and appearances, which affects the accuracy of clinical tests.

Innovation Solution

A feces sampling container equipped with a feces sampling stick, a container body, and a fitting body featuring a dual leveling hole system and a helical structure for excess feces removal, along with a collected-feces detecting domain and a label for external confirmation of collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple feces sampling container is used, then the device complexity is reduced, but the sampling amount varies greatly due to different feces characteristics

Engineering Contradiction:
Improvecontainer structureVSAvoidsampling amount consistency
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The container is divided into distinct functional segments: a sampling stick with sampling part, a fitting body with leveling holes, and a container body. This segmentation allows each part to perform its specific function - the sampling stick collects feces, the fitting body controls excess removal through leveling holes, and the container body stores the sample, thereby achieving consistent sampling without complex overall structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fitting body acts as an intermediary component between the sampling stick and the container body. It includes a tubular guide part that guides the sampling stick and leveling holes that remove excess feces. This intermediary structure mediates the transition from variable feces collection to standardized sampling by controlling and regulating the feces flow and amount

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If conventional feces sampling containers are used, then the device structure is simple, but it is difficult to confirm from outside whether feces have been collected

Engineering Contradiction:
Improvecontainer structureVSAvoidfeces collection confirmation
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The tubular guide part of the fitting body is designed with different translucency levels - transparent or translucent portions allow visual detection of feces collection from outside. When feces are collected in the sampling stick, they become visible through the transparent/t translucent sections of the tubular guide part, providing clear external confirmation of collection status without requiring complex detection mechanisms

Inventive Principle:
Principle #32Color changes

3Device complexity

If feces sampling containers without leveling holes are used, then the device complexity is reduced, but the sampling amount varies due to excess feces attachment

Engineering Contradiction:
Improvefitting body structureVSAvoidsampling amount consistency
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The fitting body includes leveling holes that extract or remove excess feces from the sampling stick. The first leveling hole removes initially attached excess feces, and the second leveling hole removes any remaining excess, ensuring only the appropriate sampling amount is retained. This extraction mechanism eliminates variable excess attachment while maintaining simple overall structure

Inventive Principle:
Principle #2Taking out (Extraction)
