Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface sanitizing technologies in confined environments face challenges in adapting to varying environmental parameters such as temperature, humidity, and microorganism resistance, leading to ineffective disinfection due to incorrect concentration and contact time of disinfectants, which can result in microbial resistance and safety concerns.
Innovation Solution
A method utilizing a sanitizing apparatus with a control unit that detects environmental parameters and adjusts the dispensing of a decontaminant in the form of mist, ensuring the correct concentration and contact time based on predefined protocols, using interchangeable single-dose packs to maintain chemical-physical integrity and monitor the sanitizing process for compliance with safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If exothermic misting technologies are used to disperse decontaminant in the air, then the sanitizing coverage is improved, but the control over concentration and contact time becomes difficult leading to ineffective disinfection
Solution Approach 1:
The system incorporates sensors that continuously monitor environmental parameters (temperature, humidity) and decontaminant concentration in real-time. This feedback is transmitted to a central processing unit that automatically adjusts the dispensing rate and duration to maintain optimal concentration levels and contact time, resolving the control reliability issue while maintaining broad sanitizing coverage
Solution Approach 2:
The patent replaces manual configuration and monitoring of misting parameters with an automated electronic control system. The mechanical/manual adjustment of decontaminant dispersion is substituted with electronic sensors, processors, and automated dispensing mechanisms that precisely control concentration and exposure time based on real-time environmental data
2Adaptability or versatility
If manual configuration by professional operator is used, then the setup flexibility is improved, but the operational complexity and human intervention requirements increase
Solution Approach 1:
The system performs self-configuration by automatically detecting environmental parameters (volume, temperature, humidity) and calculating optimal decontaminant dispensing parameters. The automated control system eliminates the need for manual setup while maintaining adaptability to different confined environments through sensor-based environmental assessment and protocol selection
3Loss of information
If sensor systems for monitoring are introduced, then the traceability and documentation are improved, but the device complexity and cost increase
Solution Approach 1:
The control system performs multiple functions: it monitors environmental parameters, controls decontaminant dispensing, tracks treatment parameters, and generates documentation all through a single integrated platform. This multi-functionality reduces overall system complexity compared to separate dedicated systems for each function while maintaining comprehensive traceability
4Productivity
If the decontaminant concentration is not optimized based on environmental parameters, then the application speed is improved, but the disinfection effectiveness decreases leading to microbial resistance
Solution Approach 1:
The system performs preliminary detection of environmental parameters (temperature, humidity, volume) before initiating decontaminant dispensing. Based on this preliminary data, the control system pre-calculates optimal concentration and dispensing rates, allowing rapid application while ensuring effectiveness from the start of the treatment process
Solution Approach 2:
The system dynamically adjusts decontaminant concentration and dispensing parameters based on real-time environmental conditions. Temperature and humidity sensors trigger automatic parameter modifications to maintain optimal disinfection effectiveness across varying environmental conditions while preserving treatment speed
