Solution Overview

Problem

Conventional pipe fittings have limited filter size, reducing filtration efficiency, and require complex removal processes, making it difficult to easily replace or clean the filter.

Innovation Solution

The design includes a body with a receiving orifice and guide slots for easy filter installation and removal, a filter valve with a driven section and operation portion, and seal gaskets for secure filtration, allowing for a larger filter size and improved accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the filter size is increased to improve filtration efficiency, then the filtration efficiency is improved, but the device complexity increases due to larger connection pipes and more complex installation structures

Engineering Contradiction:
Improvefiltration efficiencyVSAvoidconnection pipe structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The filter assembly is segmented into a filter element and a filter holder that can be independently assembled and disassembled. The filter element can be removed from the filter holder for cleaning or replacement without affecting the connection pipes or other system components, thus allowing a larger filter size without increasing overall device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter element is extracted as a separate removable component from the connection structure. This allows the filter to be independently sized and replaced without modifying the connection pipes or fitting body, resolving the contradiction between filter size and device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the filter is made removable for easy cleaning and replacement, then the ease of operation is improved, but the reliability decreases due to potential leakage or improper reassembly

Engineering Contradiction:
Improvefilter removal and installationVSAvoidsealing performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Sealing elements (such as O-rings or gaskets) are pre-installed on the filter holder or filter element before the filter assembly is put into service. These sealing elements ensure proper sealing upon reassembly, maintaining reliability while allowing easy removal and installation of the filter element.

Inventive Principle:
Principle #10Preliminary action

AI summary

Pipe fittings with a filter (30) contain a body (10), a filter valve (20), and two seal gaskets (27). The body (10) includes a first connection pipe (11) and a second connection pipe (12), a receiving orifice (13), and at least one guide slot (14). The filter valve (20) includes a driven section (21) and an operation portion (25). The two seal gaskets (27) are accommodated in the first peripheral groove (22) and the second peripheral groove (23) respectively. The driven section (21) has a first peripheral groove (22), a second peripheral groove (23), and a filtration orifice (24) defined between the first peripheral groove (22) and the second peripheral groove (23) and communicating with the driven section (21), and at least one fixing bolt (26) mounted between the operation portion (25) and the first peripheral groove (22) and extending outward from the driven section (21). The at least one fixing bolt (26) slides into the at least one guide slot (14) respectively so that the filter valve (20) is accommodated in the receiving orifice (13).
