Solution Overview
Problem
Conventional water bottles and pitchers often lack built-in filters to remove contaminants like chlorine and other chemicals from water, and existing filter solutions do not provide high enough flow rates for efficient filtration.
Innovation Solution
A gravity-flow filter assembly with a cap and filter assembly that includes a fill aperture, pour aperture, and filtration media, allowing for the connection of a filter cartridge with stainless steel mesh and granular activated carbon, enabling effective filtration of liquids at high flow rates without pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter is added to remove contaminants from water, then water quality is improved, but flow rate decreases
Solution Approach 1:
The filter assembly is divided into multiple functional layers including a sediment filter layer for particulate removal, an activated carbon layer for chemical filtration, and a hollow fiber membrane layer for fine filtration. This segmentation allows each layer to specialize in removing different types of contaminants while maintaining overall high flow rate by distributing the filtration workload across multiple pathways
Solution Approach 2:
The filter assembly utilizes porous materials with optimized pore structures and sizes tailored to specific filtration requirements. The hollow fiber membranes and activated carbon are selected for their high porosity and surface area, enabling effective contaminant removal while preserving water flow rate through the filter media
2Object-affected harmful factors
If filtration media is added to remove contaminants, then purification effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple filtration functions are merged into a single integrated filter assembly that combines sediment filtration, activated carbon filtration, and hollow fiber membrane filtration in one unit. This consolidation achieves comprehensive purification effectiveness while simplifying the overall system by eliminating the need for separate filtration devices
Solution Approach 2:
The filter assembly is designed as a multi-functional component that can be installed in various container types (water bottles, pitchers, dispensers) and performs multiple filtration functions simultaneously. The universal design allows the same filter assembly to handle different flow rates and contaminant types without requiring separate specialized filters
