In-Mold Piping Filter Integrating Joint and Filter Member

Solution Overview

Problem

Conventional in-mold piping filters face challenges such as complex assembly, high production costs, and difficulty in handling small filter components, which increase man-hour requirements and assembly complexity.

Innovation Solution

An in-mold piping filter is created using plastic injection molding, where the joint and filter member are integrally formed, eliminating the need for separate assembly and reducing production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the filter member is installed separately in the joint opening, then the filtering function is achieved, but the assembly complexity and production cost increase

Engineering Contradiction:

Improvefiltering functionVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The filter member and joint body are merged into a single integrated component formed by injection molding. The filter member is positioned within the joint body and secured through the molding process, eliminating the need for separate assembly steps while maintaining the filtering function.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If the filter member is installed separately in the joint opening, then the filtering function is achieved, but the production cost increases

Engineering Contradiction:

Improvefiltering functionVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The filter member and joint body are merged into a single integrated component formed by injection molding. The filter member is positioned within the joint body and secured through the molding process, eliminating the need for separate assembly steps while maintaining the filtering function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The filter member is pre-positioned and secured within the joint body during the injection molding process itself, before the joint is removed from the mold. This preliminary action eliminates subsequent assembly operations and reduces production costs.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the filter member is placed in the opening and pressed into a ring groove, then the filter is secured, but the man-hour and assembly complexity greatly increase

Engineering Contradiction:

Improvefilter securingVSAvoidman-hour

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The filter member is pre-positioned and secured within the joint body during the injection molding process itself, before the joint is removed from the mold. This preliminary action eliminates subsequent assembly operations and reduces production costs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The injection molding process automatically secures the filter member within the joint body through the molding parameters and cavity design, without requiring manual intervention or additional assembly operations. The system serves itself by integrating the securing function into the primary manufacturing process.

Inventive Principle:

Principle #25Self-service

AI summary

An in-mold piping filter includes: a join made by plastic injection molding and having a tubular body. Two ends of the tubular body are respectively formed with the opening, and the two openings provide a connection, so that a complete pipeline is constructed and fluid can be transported through the joint. Moreover, the filter member is integrally formed inside the tubular body during the injection molding, and the filter member includes a dividing plate. The dividing plate has a plurality of filter holes.
