Artificial Feces Composition for Cleaning Product Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial feces alternatives are inconsistent and fail to accurately mimic the chemical and physical behavior of real feces, making it difficult to conduct experiments on cleaning products and waste handling without using actual feces, which poses health risks and is culturally repugnant.
Innovation Solution
A composition of artificial feces comprising dried vegetables, fiber, yeast, and fatty acids, with adjustable water content and preservatives, designed to simulate the appearance, texture, and behavior of real feces, allowing for safe and effective experimentation on cleaning products and waste handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real feces is used in experiments, then the chemical and physical behavior can be accurately studied, but health risks and cultural repugnance increase
Solution Approach 1:
The patent creates artificial feces that copies the chemical and physical properties of real feces including composition, texture, adhesion, and decomposition behavior. This allows researchers to study feces behavior without handling real feces, eliminating health risks while maintaining experimental accuracy through faithful replication of target properties
2Object-affected harmful factors
If commercially available artificial feces is used, then health risks are reduced, but the results are inconsistent with real feces experiments
Solution Approach 1:
The patent systematically adjusts multiple parameters including water content (50-80%), composition ratios, texture, and decomposition rate to match real feces properties. This multi-parameter optimization ensures that artificial feces behaves consistently with real feces in cleaning and waste handling experiments while maintaining safety
Solution Approach 2:
The artificial feces uses composite materials including vegetable matter, fiber, yeast, and fatty acids in specific combinations to replicate the complex properties of real feces. This composite approach allows faithful reproduction of chemical and physical behavior including adhesion, cohesiveness, and decomposition patterns
3Ease of manufacture
If artificial feces mimics only a handful of aspects, then manufacturing is simplified, but the applicability to real feces scenarios is reduced
Solution Approach 1:
The artificial feces formula is designed to be universally applicable across multiple experimental scenarios including cleaning product testing, waste handling evaluation, absorbent article assessment, and skin contact studies. The composition covers diverse properties such as adhesion to different surfaces, cohesiveness, texture variations, and decomposition behavior, making it versatile for various real feces scenarios
