Innovation Solution
A ceramic filter made from a composite material comprising semi-refractory clay, ground rice hull or sawdust, clinoptilolite, and colloidal silver, which filters out 99% of harmful substances and improves water taste, combined with a process for cleaning and producing the filter, and a container system for liquids that uses these filters to promote tap water consumption without plastic waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable plastic water bottles are used, then water consumption is convenient and portable, but plastic pollution increases and environmental damage worsens
Solution Approach 1:
The patent replaces disposable plastic bottles with reusable ceramic filters that can be cleaned and reused multiple times. The ceramic filter is designed to be durable yet affordable, eliminating the need for continuous disposal of plastic bottles while maintaining convenient water access.
Solution Approach 2:
The patent implements a cleaning process that recovers and reuses the ceramic filter instead of discarding it. The filter can be cleaned by soaking in vinegar or boiling water, allowing it to be reused indefinitely, thus preventing plastic waste accumulation.
2Object-generated harmful factors
If ceramic filters are used to filter water, then plastic waste is eliminated and environmental sustainability improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent uses composite materials consisting of ceramic particles mixed with binding agents to create the filter structure. This composite approach simplifies manufacturing while maintaining filtration effectiveness, as the ceramic particles provide the filtering function and the binder holds the structure together.
Solution Approach 2:
The ceramic filter is designed with a porous structure that naturally occurs in ceramic materials when fired at appropriate temperatures. This porosity provides the filtration function without requiring complex mechanical structures, simplifying the overall device design while eliminating plastic waste.
3Reliability
If ceramic filters with porous structure are used, then filtration effectiveness improves and water quality increases, but the manufacturing precision and production difficulty increase
Solution Approach 1:
The patent controls the porosity and filtration effectiveness by adjusting firing temperature and ceramic particle size during manufacturing. By changing these parameters within specific ranges, the filter achieves reliable filtration without requiring extremely precise manufacturing tolerances.
Solution Approach 2:
The ceramic filter manufacturing process utilizes hydraulic pressure during forming to create consistent porous structures. The water-based slurry is pressed into molds under controlled pressure, ensuring uniform porosity distribution without requiring complex precision machining.
