Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilizing methods using ozone gas struggle with diffusibility within the chamber, requiring high output ozone generators that increase the size of the sterilizer apparatus, compromising efficiency and space constraints.
Innovation Solution
A sterilizing method and apparatus that utilize a buffer tank to store ozone gas produced by an ozone generator, allowing for indirect injection into the chamber, enhancing ozone gas diffusibility without increasing the apparatus size, combined with hydrogen peroxide vapor injection for improved sterilization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ozone generator size is increased to improve ozone gas diffusibility, then the diffusibility of ozone gas is improved, but the size of the sterilizing apparatus increases
Solution Approach 1:
A buffer tank is introduced as an intermediary component between the ozone generator and the sterilization chamber. The buffer tank stores ozone gas and enables controlled injection into the chamber, improving ozone gas diffusibility without requiring a larger ozone generator. This mediator allows the system to achieve better gas distribution while maintaining a compact apparatus configuration.
Solution Approach 2:
Ozone gas is prepared in advance by filling the buffer tank with ozone gas before the actual sterilization process. This preliminary action allows the ozone gas to be ready for injection when needed, improving the efficiency and diffusibility of ozone gas delivery without requiring continuous high-output generation, thus avoiding apparatus size increase.
2Productivity
If a high-output ozone generator is used to enhance ozone gas diffusibility, then the sterilization efficiency is improved, but the apparatus size increases
Solution Approach 1:
The buffer tank serves as a mediator that decouples the ozone generation process from the injection process. Instead of requiring a high-output generator to continuously produce ozone, the system generates ozone at a lower rate, stores it in the buffer tank, and then injects it as needed. This maintains sterilization efficiency while avoiding the need for a large high-output generator.
Solution Approach 2:
The system performs preliminary ozone generation and storage in the buffer tank before the injection phase. This allows the use of a lower-output generator that operates for a longer duration to fill the buffer, rather than requiring a high-output generator to deliver all ozone at once. The preliminary preparation maintains sterilization effectiveness while reducing apparatus size.
