Solution Overview

Problem

Conventional compressed air purifiers face issues with frequent filter element replacement due to clogging, leading to increased pressure loss and difficulty in managing cleanliness, especially when pressure is continuously supplied, as foreign substances are discharged to pneumatic devices.

Innovation Solution

A separator with a multi-flow drain design featuring a housing, inner and outer barrels, plunger, floater, and discharge valve, which allows continuous filtering and intermittent discharge of moisture through buoyancy-driven operation, using vortex forming members and filter members to separate and accumulate contaminants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional filter element with micropores is used to remove moisture, then moisture can be captured and removed from compressed air, but the micropores become clogged over time requiring frequent replacement and increasing pressure loss

Engineering Contradiction:

Improvemoisture removal capabilityVSAvoidfilter element replacement frequency

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The filter element is divided into an outer filter case and an inner filter element that can be independently removed. The inner filter element is detachably coupled to the outer filter case, allowing easy replacement without replacing the entire filter assembly. This segmentation reduces maintenance complexity and device downtime.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner filter element is extracted as a separate, removable component from the outer filter case. This allows the filter element to be easily removed and replaced without disassembling the entire filter housing, significantly reducing maintenance effort and time while maintaining effective moisture removal.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the filter element micropores become more clogged, then more moisture is removed, but the cross-sectional area for air passage decreases making it difficult for compressed air to pass through and increasing pressure loss

Engineering Contradiction:

Improvemoisture capture efficiencyVSAvoidpressure loss

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The filter element is designed with a collapsible structure that can dynamically adjust its configuration. When the filter element becomes clogged, it can collapse inward to maintain a larger effective cross-sectional area for air passage, reducing pressure loss while continuing to capture moisture effectively.

Inventive Principle:

Principle #15Dynamics

3Productivity

If pressure is continuously supplied from the compressor, then compressed air flows continuously through the system, but foreign substances accumulated in separated state are discharged to the pneumatic device along upward airflow making it difficult to manage cleanliness

Engineering Contradiction:

Improvecontinuous airflowVSAvoidcontaminant discharge to pneumatic device

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The drain plug is extracted as a separate, easily removable component from the filter element. This allows operators to easily remove accumulated foreign substances and condensate from the bottom of the filter element without disassembling the entire filter housing, preventing contaminant discharge to the pneumatic device while maintaining continuous airflow.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The filter element includes a built-in drain plug that enables self-draining of condensate and accumulated contaminants. This self-service feature allows the filter to automatically or manually discharge harmful factors without requiring external intervention or system shutdown, maintaining continuous productivity while managing cleanliness.

Inventive Principle:

Principle #25Self-service
