Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial processes face challenges with the storage and purification of hazardous and unstable gases due to safety concerns, decomposition, and impurity contamination, particularly in the semiconductor industry, where high-pressure cylinders pose risks and low-level impurities affect the quality of thin film electronic and optoelectronic cells.
Innovation Solution
The use of ionic liquids as a solvent mixture within vessels for selective dispensing and purification, which includes contacting the gases with a mixture of ionic liquids and cosolvents to retain impurities and stabilize unstable gases, thereby reducing decomposition and enhancing gas purity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional water treatment methods are used, then water purification is achieved, but the system is complex and requires multiple separate units
Solution Approach 1:
The patent combines multiple water treatment functions (filtration, sedimentation, UV sterilization, ozone treatment, activated carbon filtration) into a single integrated tank system. All treatment stages occur within one unified structure rather than requiring separate equipment, thereby reducing system complexity while maintaining comprehensive purification effectiveness.
Solution Approach 2:
The treatment tank serves multiple functions simultaneously: it acts as a filtration chamber, sedimentation basin, UV sterilization chamber, and ozone treatment vessel. This multi-functionality eliminates the need for multiple specialized units, simplifying the overall system architecture while ensuring thorough water purification.
2Reliability
If multiple treatment stages are implemented, then water purification quality is improved, but the device complexity increases
Solution Approach 1:
The treatment process is segmented into distinct functional zones within the same tank: a filtration section with porous plates, a sedimentation section, a UV sterilization section, and an ozone treatment section. This segmentation allows multiple treatment stages to occur sequentially in one location, improving purification quality without proportionally increasing device complexity.
Solution Approach 2:
Multiple treatment components are nested within the single tank structure. The filtration elements, UV lamps, ozone injection points, and activated carbon filters are all contained within the same vessel, with each component occupying a specific zone. This nesting approach enables comprehensive multi-stage treatment while maintaining a compact, simple external structure.
3Volume of moving object
If a compact storage system is used, then space efficiency is improved, but access for treatment and maintenance becomes difficult
Solution Approach 1:
The tank incorporates a removable lid and accessible openings that allow dynamic access to internal components. The lid can be opened or removed to facilitate maintenance of UV lamps, filtration elements, and ozone injection systems, while the tank maintains its compact closed structure during operation to preserve space efficiency and prevent contamination.
