Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentration ozone is used for disinfection, then disinfection effectiveness is improved, but harmful effects on materials and electronic components worsen
Solution Approach 1:
The system dynamically adjusts ozone concentration parameters in real-time based on container type, cargo characteristics, and disinfection progress. By changing concentration levels during the disinfection process rather than maintaining a fixed high concentration, the system achieves effective disinfection while preventing damage to sensitive materials and electronic components.
Solution Approach 2:
The disinfection process uses periodic cycles of high and low ozone concentration. High concentration phases are used briefly for initial disinfection, followed by lower concentration phases to complete the process safely. This periodic variation allows effective pathogen elimination while limiting cumulative exposure that could harm materials and electronics.
2Productivity
If ozone injection speed is increased to reduce disinfection time, then productivity is improved, but ozone concentration control worsens
Solution Approach 1:
The ozone injection system divides the container into multiple zones with separate injection points. Ozone is injected simultaneously at different locations rather than from a single point, which segments the delivery process. This segmentation maintains uniform concentration distribution even at high injection speeds, preventing localized over-concentration while achieving rapid overall disinfection.
Solution Approach 2:
The system uses computational algorithms as an intermediary between the injection speed control and concentration monitoring systems. The algorithm predicts concentration distribution based on injection parameters and adjusts injection rates dynamically to maintain uniformity. This intermediary processing enables high-speed injection while preserving concentration control precision.
3Device complexity
If existing disinfection methods are used, then simplicity is maintained, but disinfection effectiveness and safety worsen
Solution Approach 1:
The ozone injection system is designed with multi-functionality to handle various container types, cargo configurations, and disinfection requirements through a single integrated platform. By incorporating adaptive control algorithms and adjustable injection parameters, the system achieves high effectiveness and safety without requiring multiple specialized devices, thus maintaining relative simplicity while improving performance.

AI summary
The invention is a system and device for the disinfection of closed containers, through the use of gaseous ozone generated on site by a novel ozone generator with high and low concentration cells, powered by an oxygen generator with its own electrical supply and comprised of a mixing device and a special connection device to the container vents, which allows the injection of ozone at very short times, with the capacity to invade all the areas and crevices within the container and the cargo, producing the disinfection and elimination of viruses, fungi, bacteria and other microorganisms from the outside of the container, for periods of time longer than the required regardless of the environmental conditions of temperature and humidity outside, ozone being a powerful viricide, which does not leave any type of waste inside the containers.
