Solution Overview
Problem
Existing decontamination systems for vehicles and enclosed areas are not efficiently designed for quick and effective disinfection of surfaces exposed to harmful viruses, bacteria, and chemicals, particularly in confined spaces like ambulances and buildings with multiple rooms.
Innovation Solution
A decontamination system comprising a portable unit with a reservoir for a disinfectant solution, pressurized air supply, and a programmable controller, connected via quick-disconnect umbilical assemblies to nozzles for timed delivery of disinfectant mist or fog, ensuring thorough surface disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chamber system is used for decontamination, then disinfection effectiveness is improved, but portability and ease of deployment deteriorate
Solution Approach 1:
The system is divided into separate functional modules: a portable delivery unit with nozzle assembly, a removable disinfectant reservoir, and a pressurized air supply system. This segmentation allows the main decontamination unit to be compact and portable while still delivering effective disinfection through the distributed nozzle system.
Solution Approach 2:
Compress air is introduced as an intermediary substance to atomize the disinfectant solution and deliver it as a fine mist through the nozzle. This intermediary mechanism enables effective disinfection coverage without requiring the entire chamber to be a fixed, large-scale structure.
2Manufacturing precision
If multiple nozzles are used for comprehensive coverage, then disinfection uniformity is improved, but system complexity increases
Solution Approach 1:
The nozzle assembly is designed as a universal multi-functional unit that can be configured with multiple nozzles in various patterns. The same basic nozzle design can be arranged in different configurations to suit different decontamination scenarios, reducing the need for multiple specialized components and simplifying the overall system.
Solution Approach 2:
The system uses pressurized air delivery through fluid lines to control multiple nozzles simultaneously. This pneumatic/hydraulic approach provides uniform disinfectant distribution to all nozzles without requiring complex individual control systems for each nozzle, thereby reducing system complexity while maintaining disinfection uniformity.
3Measurement precision
If timed intervals are implemented for disinfectant delivery, then disinfection precision is improved, but control system complexity increases
Solution Approach 1:
The controller is programmed to operate the pressurized air supply and disinfectant delivery system in periodic timed intervals. This periodic action ensures precise disinfection timing and dosage control without requiring complex real-time sensing and adjustment systems, achieving disinfection precision through simple time-based control logic.
