Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filter systems are bulky, difficult to maintain, require excessive torque for sealing, have a large footprint, and are prone to leakage, making filter replacement and maintenance cumbersome and inefficient.
Innovation Solution
A modular water filter system with a monoblock housing design featuring a channel for water flow at the bottom, allowing easy filter access and replacement, and a pressure relief valve for minimizing air pressure, along with a cover member with ramps for secure cap engagement, eliminating the need for wrenches and threads, and ensuring a liquid-tight seal with minimal effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional threaded caps are used for sealing filter canisters, then a liquid-tight seal can be achieved, but excessive torque is required and wrenches are needed for installation
Solution Approach 1:
The patent replaces the traditional threaded mechanical sealing system with a cam-actuated lever system. The lever applies progressive mechanical advantage to compress the seal against the canister flange, eliminating the need for threads and high-torque fastening while achieving equivalent or superior seal integrity through controlled, distributed pressure application.
Solution Approach 2:
The patent introduces a compliant seal element (gasket or O-ring) as an intermediary between the cap and canister flange. This seal mediator distributes the clamping force from the lever mechanism across the entire sealing surface, ensuring uniform contact pressure and preventing leakage without requiring high localized forces that would demand threaded fasteners.
2Reliability
If multiple filters are used in series to remove different contaminants, then filtration effectiveness is improved, but filter replacement becomes more complex and time-consuming
Solution Approach 1:
The patent divides the filtration system into modular filter cartridges, each containing a specific filter medium for targeting particular contaminants. Each cartridge is independently replaceable through the unified lever-actuated sealing mechanism, allowing users to swap individual filters without affecting others, thus maintaining high filtration effectiveness while minimizing maintenance complexity and time.
Solution Approach 2:
The patent designs a universal mounting interface and sealing mechanism that accommodates multiple types of filter cartridges with different media and configurations. The same lever-actuated cap system seals all filter types, providing a multi-functional platform that simplifies maintenance across diverse filtration needs while ensuring consistent seal quality and filtration performance.
3Strength
If the filter canister is designed as a single integrated unit, then structural strength is improved, but filter replacement requires complete disassembly of the system
Solution Approach 1:
The patent segments the canister into a permanent housing and removable filter cartridge components. The housing maintains structural integrity and houses the inlet/outlet connections and sealing mechanism, while the filter cartridge is designed as a separate, easily replaceable unit that interfaces with the housing through the lever-actuated seal, enabling quick filter changes without disturbing the main canister structure.
Solution Approach 2:
The patent extracts the filter element from the canister housing as a separate, self-contained cartridge that can be independently removed and replaced. This extraction allows the filter media to be serviced separately from the structural housing and sealing mechanism, maintaining overall system strength while dramatically simplifying maintenance operations.
4Productivity
If the filter is positioned vertically to facilitate drainage, then water drainage efficiency is improved, but the system occupies more vertical space
Solution Approach 1:
The patent transitions from purely vertical filter positioning to a horizontal or angled configuration where the lever-actuated seal and cam mechanism provide the necessary sealing force through lateral or diagonal leverage rather than relying on vertical gravity-assisted drainage. This dimensional change allows the system to maintain effective drainage through the seal design while reducing vertical footprint and enabling more flexible spatial installation.
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
The system is lightweight, easy to use, reduces the effort required for filter changes, minimizes leakage, and facilitates efficient water drainage, making maintenance simpler and more cost-effective while maintaining a compact footprint.
Implementation Method 1
a pressure relief valve for minimizing air pressure
Implementation Method 2
Either the inner wall of the receptacle or the outer wall of the tubular member has an O-ring seal thereon. This O-ring seal forms a liquid-tight seal between the receptacle and the tubular member.
Implementation Method 3
The filter has an interior passageway that opens to a filter media. The filter media is disposed such that water flows from the channel and into the interior passageway, through the filter media and into the annulus.

AI summary
A water filter system has a housing with the channel formed adjacent a bottom thereof and at least one chamber formed therein, and at least one filter removably received in the chamber. The channel is adapted to connect with a water inlet line. The channel is also adapted to connect with a water outlet line. The filter is in communication with the channel at a bottom thereof. The filter and an inner wall of the chamber define an annulus therebetween. The filter has an interior passageway that opens to a filter media. The filter media is disposed such that water flows from the channel and into the interior passageway, through the filter media, and into the annulus. The annulus then communicates with the channel.
