Replaceable Active Water Filter Components to Cut Material Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water filtration systems require replacement of the entire filter or its operative component assembly, leading to inefficiencies and increased costs due to limited lifespan of filter components.
Innovation Solution
A water filtration system with replaceable active components, where only the active components are replaced when needed, utilizing a filter housing with a mesh lining to retain the components and prevent their exit through portal openings, allowing water to pass while retaining the active components within the filter body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire filter or operative component assembly is replaced when filter components reach their lifespan, then the filtration function is restored, but material waste increases and costs increase
Solution Approach 1:
The filter assembly is divided into separate components: a reusable filter housing and replaceable active filter components (carbon block, sediment filter). Only the active components that reach their lifespan are replaced, while the housing remains in use. This segmentation allows selective replacement of consumable parts without discarding the durable housing structure.
Solution Approach 2:
The design enables discarding only the depleted active filter components (carbon block, sediment filter) while recovering and retaining the reusable filter housing for continued use. This partial discarding approach minimizes material waste compared to replacing the entire assembly, as the housing structure is preserved and reused multiple times.
2Reliability
If the entire filter assembly is replaced when components wear out, then reliable filtration is maintained, but system lifespan is reduced and costs increase
Solution Approach 1:
By segmenting the filter into a permanent housing and temporary active components, the system allows the housing to serve indefinitely while only the consumable elements are periodically replaced. This extends the overall system lifespan since the durable housing structure is not discarded with each filter change.
Solution Approach 2:
The reusable housing is recovered and retained for continuous use, while only the depleted active components are discarded. This recovery approach maintains reliable filtration over an extended period by preserving the functional housing structure across multiple filter replacement cycles.
3Loss of substance
If replaceable active components are implemented, then material waste is reduced and system lifespan is extended, but device complexity increases
Solution Approach 1:
The filter is segmented into a housing and removable active components (carbon block, sediment filter). This segmentation enables selective replacement of only the consumable elements, reducing material waste. The modular design, while adding some structural elements for component retention, simplifies the replacement process and reduces overall complexity compared to replacing entire assemblies.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and cost-effective filtration by allowing replacement of only the active components, extending the lifespan of the filtration system and reducing waste by minimizing the need to replace the entire filter assembly.
Implementation Method 1
The mesh lining is configured to retain the active filter components within the filter body, such that the mesh lining allows water to exit the inner chamber through the portals via openings in the mesh lining while not allowing the active filter components to exit the inner chamber through the portal openings

AI summary
A water filtration system with replaceable active components. The water filtration system includes an outer housing, an inner filter canister, and a housing cap. The outer housing includes an inlet opening and an outlet opening. The housing cap includes a cap inlet opening. The inner filter canister filters water entering through the cap inlet opening. The outer housing retains and holds replaceable active filter components. The outer housing retains and holds the inner filter canister within the outer housing. The inner filter canister includes a connector for coupling to a connector on the underside of the housing cap. The housing cap engages with the inlet opening to secure the inner filter canister and the active filter components within the outer housing. Water exiting from the inner filter canister will be further filtered by the active filter components before exiting the outer housing via the outlet opening.
