Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water filtration systems face challenges in achieving enhanced contaminant reduction performance, particularly in residential applications, where increased physical dimensions or reduced pore sizes are required, and existing combinations of activated carbon and UV technologies are mechanically complex and costly, with limitations in microbiological reduction and space usage.
Innovation Solution
A water filtration assembly incorporating a filtration media block with a hollow cylindrical configuration and an electromagnetic radiation module, where water passes through the media block and is treated by an adjacent electromagnetic radiation source, such as UV light, within a compact filtration housing, allowing for effective contaminant reduction without the need for increased size or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If activated carbon-based filtration is used to reduce contaminants, then contaminant reduction performance is improved, but the physical dimensions of the product must be increased
Solution Approach 1:
The electromagnetic radiation source is positioned inside the hollow cylindrical configuration of the filtration media block, nesting one treatment mechanism within another. This allows water to first pass through the filtration media walls and then through the radiation passageway, combining two treatment functions in a compact nested structure that reduces the overall footprint while maintaining enhanced contaminant reduction performance
Solution Approach 2:
The patent combines activated carbon-based filtration media with electromagnetic radiation treatment in a single integrated assembly. The filtration media block and radiation module are positioned adjacent to each other within the same housing, merging two separate treatment technologies into one compact unit that delivers both adsorptive and radiative contaminant reduction without requiring separate devices
2Reliability
If pore size is reduced to improve contaminant reduction performance, then filtration effectiveness is improved, but feed pressure must be increased or flow rate reduced
Solution Approach 1:
The system merges adsorptive filtration through the media block walls with electromagnetic radiation treatment in the passageway. This combination allows the use of optimized pore sizes for contaminant capture while the radiation component handles microbiological reduction, eliminating the need to compromise flow rate or increase pressure to achieve comprehensive contaminant reduction
3Reliability
If combined AC and UVC modules are used to improve contaminant reduction, then microbiological reduction is improved, but device complexity and footprint are increased
Solution Approach 1:
The patent integrates the electromagnetic radiation source directly adjacent to the filtration media block within a single housing, merging what would traditionally be separate AC and UVC modules into one unified assembly. This integration eliminates the need for multiple replaceable consumables and complex mechanical connections, reducing device complexity while maintaining effective microbiological reduction
Solution Approach 2:
The radiation passageway is positioned through the hollow cylindrical filtration media block, nesting the radiation treatment function within the filtration structure. This nested configuration allows both treatment mechanisms to work in sequence within a compact footprint, reducing the space required compared to side-by-side module arrangements
4Reliability
If combined AC and UVC modules are used to improve contaminant reduction, then treatment effectiveness is improved, but the footprint of the system is increased
Solution Approach 1:
The hollow cylindrical filtration media block contains a central passageway through which water flows after passing through the media walls. The electromagnetic radiation source is positioned within this passageway, nesting the radiation treatment function inside the filtration structure. This nested arrangement significantly reduces the footprint compared to external module configurations

Implementation Method 1
Water treatment using adsorptive media has been in practice since ancient times. Although, modern Activated Carbon-based (AC) technologies allow the reduction of multiple health-related contaminants
Implementation Method 2
Water treatment using germicidal ultraviolet (UV) radiation has also been practiced for several decades

AI summary
A water filtration assembly for an appliance is disclosed having a filtration housing, a filtration media block positioned within the filtration housing, and an electromagnetic radiation module having an electromagnetic radiation source positioned within the filtration housing. The electromagnetic radiation source is positioned adjacent to the filtration media block. Further, the filtration media block has a hollow cylindrical configuration defining a radiation passageway. As such, water is configured to enter a water inlet of the filtration housing, travel through one or more walls of the filtration media block for treatment and into the radiation passageway for further treatment by the electromagnetic radiation source, and exit a water outlet of the filtration housing.
