Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ozone is unstable and difficult to store due to its high reactivity and short half-life, posing challenges for its practical use and storage, especially in large quantities, and existing methods are either dangerous or inefficient.
Innovation Solution
A process to produce a solid ozone storage material using cyclodextrins and/or cyclodextrin derivatives, which are contacted with ozone to stabilize and store it, allowing for long-term storage and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ozone is stored in its pure state or mixture under ambient conditions, then storage capacity is improved, but stability and lifetime deteriorate due to rapid decomposition
Solution Approach 1:
The patent introduces cyclodextrin as an intermediary substance that forms an inclusion complex with ozone. The cyclodextrin cavity encapsulates the ozone molecule, acting as a mediator that protects ozone from decomposition while enabling storage. This resolves the contradiction by providing both storage capacity and stability through the host-guest complexation mechanism.
Solution Approach 2:
The patent changes the physical state parameter of ozone from gaseous to solid form through inclusion complexation with cyclodextrin. This parameter change enables ozone to be stored in solid form at ambient conditions, simultaneously achieving high storage capacity and enhanced stability by altering the fundamental state of ozone.
2Ease of operation
If an on-site ozoniser is used to produce ozone, then ozone availability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent applies preliminary action by pre-complexing ozone with cyclodextrin to create a stable solid material that can be stored and transported. This eliminates the need for on-site ozone generation equipment, as the ozone is already prepared and stabilized in advance, thereby simplifying the system and improving ease of operation.
Solution Approach 2:
The patent extracts the ozone generation function from the storage and usage system. By separating ozone production (done in advance) from storage and application, the complex ozoniser device is removed from the point-of-use system, leaving only the simple solid ozone-cyclodextrin material that can be easily handled and applied.
3Stability of the object's composition
If temperature is lowered to extend ozone lifetime, then stability is improved, but operational complexity and cost increase
Solution Approach 1:
The patent changes the stabilization mechanism from temperature-dependent (requiring low temperatures) to chemical structure-dependent (using cyclodextrin inclusion complex). This parameter change allows ozone to be stabilized at ambient temperatures without complex cooling systems, resolving the contradiction between stability and operational complexity.
