Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing contamination transmission, such as immediate and long-acting disinfection, are inadequate in effectively minimizing cross-contamination incidents, particularly in healthcare settings, and fail to optimize resource scheduling to minimize cross-contamination probabilities at convergence points.
Innovation Solution
A dynamic resource system (DRS) utilizing a combination of immediate and fast-acting persistent decontamination methods, integrated with machine learning and deterministic algorithms, to identify and manage contamination pathways, optimize resource scheduling, and minimize cross-contamination probabilities through dynamic decontamination strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If immediate disinfection methods are used, then contamination is removed at a specific time, but the method does not have persistent impact post-disinfection
Solution Approach 1:
The system combines immediate disinfection methods (UV-C irradiation, chemical disinfectants) with fast-acting persistent methods (photocatalytic coatings, antimicrobial surfaces) into an integrated decontamination system. This merging allows the system to achieve both rapid contamination removal and sustained protective effect, resolving the contradiction between speed and duration of action.
Solution Approach 2:
The system applies persistent protective coatings and treatments in advance before contamination occurs or as a follow-up to immediate disinfection. This preliminary action ensures that surfaces maintain antimicrobial properties over time, providing ongoing protection without requiring frequent reapplication, thus extending the duration of action while maintaining rapid effectiveness.
2Duration of action of stationary object
If long-acting persistent methods are used, then long-term protection is achieved, but the action time required to prevent transference is slow (greater than 2 hours)
Solution Approach 1:
The system employs composite decontamination approaches combining multiple mechanisms: photocatalytic materials (TiO2 coatings) that activate upon light exposure, antimicrobial peptides, and conventional disinfectants. These composite solutions provide both immediate antimicrobial activity and long-lasting protective effects, achieving rapid contamination prevention while maintaining extended duration of action.
Solution Approach 2:
The system changes operational parameters by controlling light exposure, temperature, and humidity to activate and optimize the performance of persistent protective methods. By adjusting these parameters, the system accelerates the onset of protective action while maintaining long-term effectiveness, thus resolving the speed-duration contradiction.
3Reliability
If resource scheduling is optimized to minimize cross-contamination, then contamination pathways are reduced, but system complexity increases
Solution Approach 1:
The system incorporates sensors, tracking devices, and monitoring systems that provide real-time feedback on resource locations, contamination risks, and pathway intersections. This feedback enables dynamic adjustment of scheduling decisions, allowing the system to optimize contamination prevention while managing complexity through data-driven automation and adaptive control mechanisms.
4Reliability
If decontamination methods are applied frequently, then cross-contamination is minimized, but adverse impact on ecosystems increases
Solution Approach 1:
The system employs biodegradable and environmentally benign decontamination agents that break down quickly after use, replacing persistent chemical disinfectants with natural alternatives such as enzymatic cleaners and plant-based antimicrobials. These short-acting but effective solutions minimize ecological accumulation and harm while maintaining contamination prevention effectiveness.
Solution Approach 2:
The system utilizes advanced oxidation processes (AOPs) such as photocatalysis and ozonation that generate highly reactive oxygen species to rapidly degrade contaminants. These methods achieve thorough decontamination with minimal chemical residues and reduced environmental persistence, lowering adverse ecological impact while maintaining high prevention effectiveness.

AI summary
A system and method for contaminant control, often infection control, with multiple time and space domains that integrate active and passive infection control devices and processes that preferably feature infection control active additives with controllable dis-passivation to limit post-consumption environmental impact. Additionally, the system executes the infection control devices and process transactions by controlling the dispatch of infection control tasks centered around a potential infection control incidence and/or cross-contamination locations from assets or personnel having probabilistic infection rates to increase compliance of infection control preventative measures.
