Solution Overview

Problem

Existing water filtration systems face challenges in handling internal pressures during filtration, requiring strong materials like steel or composite plastics, and often need periodic access for maintenance, while multi-filtration systems are cumbersome to assemble and transport due to the need for various housings and cartridges.

Innovation Solution

A pressure-sealed closing system for water filtration housings featuring a lid member and lock member configuration that uses internal pressure to seal the housing, allowing for easy assembly and maintenance without the need for multiple housings, and enabling the use of multiple filtration methods in a single system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If high-strength materials like steel or composite plastics are used for the housing, then the housing can withstand substantial internal pressures, but the housing becomes expensive and heavy

Engineering Contradiction:
Improvehousing strengthVSAvoidhousing weight
Core Design Contradiction:
StrengthVSWeight of stationary object

Solution Approach 1:

The patent converts the harmful internal pressure into a beneficial locking force. The pressure-generated force automatically locks the closing assembly in place, eliminating the need for heavy materials to contain the pressure. The pressure that would normally be a hazard becomes the mechanism that secures the housing closure.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The closing assembly is designed to automatically lock itself using the internal pressure generated during filtration. The pressure acts on the lock member to engage with the head portion, creating a self-locking mechanism that requires no additional heavy structural support.

Inventive Principle:
Principle #25Self-service

2Strength

If high-strength materials like steel or composite plastics are used for the housing, then the housing can withstand substantial internal pressures, but the housing becomes expensive

Engineering Contradiction:
Improvehousing strengthVSAvoidhousing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent converts the harmful internal pressure into a beneficial locking force. The pressure-generated force automatically locks the closing assembly in place, eliminating the need for expensive high-strength materials to contain the pressure.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The closing assembly automatically locks itself using the internal pressure generated during filtration, eliminating the need for expensive specialized materials and simplifying manufacturing requirements.

Inventive Principle:
Principle #25Self-service

3Ease of repair

If the housing provides periodic access for maintenance, then filter cartridges can be replaced, but the housing must be designed to allow opening while withstanding internal pressures

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidpressure containment
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The closing assembly transitions from a static sealed position to a dynamic opened position. The threaded engagement allows the lid to be dynamically adjusted and removed for maintenance while maintaining pressure containment during operation. The system moves between sealed and accessible states as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The internal pressure that would prevent opening is converted into a locking force that secures the closed position during filtration. When maintenance is needed, the pressure is released and the same pressure mechanism that contained it now locks the closed position, ensuring reliable sealing when operational.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Adaptability or versatility

If multiple filtration methods are used in a single system, then filtration versatility is improved, but assembly planning and configuration become more complex

Engineering Contradiction:
Improvefiltration method versatilityVSAvoidassembly configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing with the pressure-sealed closing assembly serves as a universal platform that can accommodate multiple different filtration cartridges and methods. The standardized housing design allows different filter types to be used in the same system without requiring specialized housing configurations for each filtration method.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The filtration system is segmented into separate replaceable cartridges within a single housing. Each cartridge can be independently selected for different filtration methods, allowing versatility while keeping the housing configuration simple and standardized.

Inventive Principle:
Principle #1Segmentation

5Adaptability or versatility

If various different housings are provided for different filtration methods, then appropriate filtration systems can be assembled, but storage and transportation become inconvenient

Engineering Contradiction:
Improvefiltration system compatibilityVSAvoidhousing storage volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

A single universal housing design can accommodate multiple filtration methods through the use of different cartridges and the pressure-sealed closing assembly. This eliminates the need to store and transport multiple specialized housings, reducing storage volume and transportation requirements while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 solution effectively manages internal pressures, simplifies maintenance and assembly, and allows for versatile use of different filtration methods within a single housing configuration, reducing costs and complexity in system installation and storage.

Implementation Method 1

A pressure generated within the housing during water filtration presses the lid member in the outward direction and causes the press section to press against the abutment section, thereby pressure sealing the housing at the head opening

AI summary

A water filtration system utilizes a housing configured to utilize various types of filter media and having a press-sealed closing system. The closing system includes a head portion defining a head opening, a lock member, and a lid member. The lock member releasably engages the head portion such that an abutment section of the lock member projects into the head opening. The lid member is received by the head portion to cover the head opening, and has an outward-facing press section configured to abut an inward facing portion of the abutment section of the lock member when the lid member is covering the head opening. Pressure generated within the housing during water filtration presses the lid member in an outward direction and causes the lid member press section to press against the abutment section of the lock member to substantially prevent disengagement of the lock member from the head portion.
