Solution Overview
Problem
Conventional isolation chambers for floatation tanks face challenges in accurately monitoring and safely disinfecting magnesium sulfate solutions, as chemical disinfectants like chlorine produce toxic by-products and are difficult to measure, posing health risks and contamination issues.
Innovation Solution
A disinfection system utilizing ultraviolet radiation and ozone injection, combined with a multi-stage filtration system and a pump for circulating the solution, ensuring thorough pathogen elimination without harmful by-products, and allowing for accurate monitoring of disinfection efficacy through dissolved ozone sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine is used for disinfection, then disinfection effectiveness is improved, but toxic by-products are generated
Solution Approach 1:
The patent replaces chemical disinfection (chlorine) with a physical disinfection system using ultraviolet (UV) radiation. The UV lamps emit germicidal UV-C light that destroys the DNA/RNA of microorganisms, providing effective disinfection without introducing chemical by-products into the magnesium sulfate solution. This substitution of chemical method with physical method resolves the contradiction between disinfection effectiveness and toxic by-product generation.
Solution Approach 2:
The patent employs ozone injection as a strong oxidant for disinfection. Ozone (O3) is a powerful oxidizing agent that kills microorganisms by oxidizing their cell walls and internal structures. Unlike chlorine, ozone decomposes into oxygen without leaving harmful residual by-products, thus achieving effective disinfection while avoiding the toxic by-product issue associated with chlorine.
2Reliability
If chemical disinfectants are used, then pathogen elimination is improved, but monitoring accuracy deteriorates
Solution Approach 1:
The patent replaces chemical disinfectants with UV radiation and ozone, which can be monitored through physical parameters. UV lamp intensity and operational status can be measured with photodetectors, and ozone concentration can be monitored with ozone sensors. This substitution enables accurate monitoring of disinfection efficacy without the measurement difficulties associated with chemical residual analysis in magnesium sulfate solutions.
3Productivity
If chlorine is used for disinfection, then disinfection speed is improved, but user safety deteriorates
Solution Approach 1:
The patent substitutes chlorine-based chemical disinfection with UV radiation and ozone injection. UV disinfection acts rapidly on microorganisms by damaging their genetic material, and ozone provides fast oxidation-based pathogen elimination. Both methods achieve quick disinfection without leaving harmful chemical residues in the solution, thereby maintaining disinfection speed while significantly improving user safety.
Solution Approach 2:
The patent employs ozone, which has a short half-life and naturally decomposes into oxygen. This short-lived disinfectant provides rapid disinfection action but disappears quickly without persisting in the solution, eliminating the safety concerns associated with residual chlorine exposure to users.
4Reliability
If chlorine is used for disinfection, then residual disinfection is improved, but harmful residues are generated
Solution Approach 1:
The patent uses ozone as a strong oxidant that provides disinfection without persistent harmful residues. Ozone decomposes naturally into oxygen within hours, providing the necessary disinfection protection during and shortly after treatment without leaving toxic remnants in the magnesium sulfate solution, unlike chlorine which persists as harmful residual chemicals.

AI summary
An isolation chamber and disinfection system. The novel system includes an enclosure for providing a sturdy, lightless and soundproofed environment and for containing a solution for supporting a user in a state of floatation; a disinfection system for disinfecting the solution, the disinfection system including an ultraviolet disinfection system and an ozone injection system; and a pump for removing the solution from the enclosure and circulating it through the disinfection system at a predetermined flow rate. The enclosure is formed from interlocking, foam-insulated panels and lined with a potable liner that holds the solution. In relationship to the isolation chamber, in accordance with the present teachings, an improved method of disinfection is taught using UV radiation with ozone injection. Ozone has a short half-life and leaves substantially no toxic byproducts. Verification of disinfection can be accomplished by monitoring the dissolved ozone, which can be determined accurately utilizing a dissolved ozone sensor system.
