Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning and disinfection devices for human waste containers face challenges such as inadequate germ destruction, particularly of spores, and the handling of aggressive, corrosive, or unstable chemical disinfectants, leading to potential contamination and operational difficulties.
Innovation Solution
A method involving an emptying step, washing with a cleaning fluid, and a disinfection step where reactive components are mixed to form a disinfectant agent in situ, ensuring thorough disinfection and reducing the need for hazardous chemical storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical disinfectants are used for disinfection, then disinfection effect is improved, but handling safety and stability deteriorate due to aggressive, corrosive, or unstable properties
Solution Approach 1:
The patent changes the chemical parameters by using reactive components that convert into disinfectant agents in situ, transforming stable storage materials into active disinfectants only when needed. This resolves the contradiction by maintaining stability during storage and transport while achieving effective disinfection during use.
Solution Approach 2:
The patent introduces reactive components as intermediaries that react to form disinfectant agents. These intermediaries are stable and safe to handle, but when combined, they produce powerful disinfectant agents in situ, thus resolving the contradiction between handling safety and disinfection effectiveness.
2Reliability
If conventional disinfection methods are used, then general disinfection is achieved, but sporicidal effect deteriorates due to inadequate germ destruction
Solution Approach 1:
The patent employs strong oxidizing agents formed from reactive components that can achieve sporicidal effects. The oxidation process is powerful enough to destroy spores and other resistant microbial forms, resolving the limitation of conventional disinfection methods.
Solution Approach 2:
The disinfectant agents are generated in situ and act quickly to destroy germs and spores, then decompose into harmless substances. This short-lived, high-impact approach achieves reliable germ destruction without requiring persistent chemical presence.
3Object-affected harmful factors
If reactive components are mixed to form disinfectant agents in situ, then handling safety is improved, but device complexity worsens due to mixing requirements
Solution Approach 1:
The system is designed to automatically mix reactive components and generate disinfectant agents without requiring complex external mixing mechanisms. The reactive components self-react upon contact, simplifying the device structure while maintaining handling safety.
Solution Approach 2:
The patent replaces complex mechanical mixing systems with chemical self-reaction mechanisms. The reactive components automatically convert into disinfectant agents through their inherent chemical properties, eliminating the need for complex mixing devices.
4Device complexity
If steam disinfection is used, then equipment simplicity is maintained, but disinfection reliability deteriorates due to insufficient spore destruction
Solution Approach 1:
The patent changes the chemical parameters of the disinfection process by introducing reactive components that form strong oxidizing disinfectant agents. This enhances the sporicidal effect beyond what steam alone can achieve, while maintaining relatively simple equipment through in situ generation.
