Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chlorine dioxide's instability and high reactivity pose challenges for its storage, transportation, and use, limiting its application due to safety concerns and high costs associated with generators, and existing formulations struggle to achieve stable solutions above 1% concentration, making its use inefficient and costly.
Innovation Solution
A solid formulation comprising Sodium Bisulfate, Trichlorisocyanuric Acid, Magnesium Sulfate, and Sodium Chlorite, optionally with additional components, that generates 10-30% chlorine dioxide when mixed with water, providing a safe, efficient, and cost-effective disinfection solution by leveraging the synergy of these components to increase yield and speed of concentration attainment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine dioxide is stored or transported in compressed form, then it can be made available for use, but the risk of explosion increases and safety is compromised
Solution Approach 1:
The invention divides the chlorine dioxide generation system into separate components: stable precursor compounds (sodium chlorite, sodium chlorate, calcium chlorite) are packaged separately from acidifying agents (citric acid, ascorbic acid, malic acid). These segments are mixed only at the point of use, preventing the hazards of storing pre-mixed unstable solutions while enabling safe transportation of individual stable components.
Solution Approach 2:
The patent uses stable intermediate compounds (solid precursor salts and dry acidifying agents) as mediators that can be safely stored and transported. These intermediaries remain inert until mixed with water and each other at the application site, where they then generate the active chlorine dioxide disinfectant. This intermediary approach resolves the contradiction between safety and operational availability.
2Reliability
If chlorine dioxide solutions are prepared at high concentrations, then disinfection efficacy is improved, but stability decreases and the solution becomes unsafe to handle
Solution Approach 1:
The invention prepares all necessary precursor compounds and acidifying agents in stable solid forms before use. These pre-prepared components can be stored indefinitely without degradation. When needed, they are simply mixed with water in controlled amounts to generate the required concentration of chlorine dioxide, ensuring both stability during storage and efficacy when applied.
Solution Approach 2:
The patent changes the physical state parameter from liquid solution to solid powder/tablet form for the precursor compounds. This parameter change enables stable storage at high effective concentrations without the instability and safety issues associated with concentrated liquid chlorine dioxide solutions. The concentration is adjusted by controlling the amount of water added during generation.
3Reliability
If chlorine dioxide generators are used to produce chlorine dioxide on-site, then safety and flexibility are improved, but the cost of acquisition, operation, and maintenance increases
Solution Approach 1:
The invention employs inexpensive, shelf-stable solid precursor compounds and acidifying agents that can be manufactured at low cost and stored indefinitely. These disposable-style components eliminate the need for expensive electronic generators, sensors, and control systems. Users simply mix the powders or tablets with water to generate chlorine dioxide, dramatically reducing acquisition and maintenance costs while maintaining safety.
Solution Approach 2:
The patent creates a self-service system where the user themselves performs the generation function by simply mixing the stable precursor compounds with water and an acidifying agent. This eliminates the need for complex automated generators requiring electricity, electronic controls, and professional maintenance. The system serves itself through basic chemical reactions that occur upon mixing, reducing operational costs.
4Ease of operation
If liquid chlorine dioxide solutions are commercialized, then ease of use is improved, but logistical costs increase due to the high water content and instability
Solution Approach 1:
The invention changes the physical state from liquid to solid for the active precursor compounds, concentrating the active ingredients in a compact, stable form. This eliminates the need to transport large volumes of water-containing solutions. The solid precursors can be transported efficiently and then converted to the required liquid concentration at the point of use by adding controlled amounts of water, reducing logistical costs while maintaining ease of use.
Solution Approach 2:
The patent segments the chlorine dioxide generation system into separate stable solid components that can be transported independently. This segmentation allows for efficient logistics by transporting only the necessary precursor compounds without excess water, then reconstituting the active solution at the application site. This approach reduces transportation and storage costs while providing the user with easy-to-use pre-measured components.
