High-Pressure Respirator Connector With Replaceable Filter Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure connectors for respirators are complex to clean and maintain, with filter changes requiring the entire connector to be detached from both the breathing gas source and pressure reducer, leading to increased wear and difficulty in restoring the sealing functionality.
Innovation Solution
A high-pressure connector is designed with a multipart configuration, where the filter device is housed in the connector upper part, allowing for simple and cost-effective replacement by detaching the upper part from the lower part, while maintaining the lower part's connection to the pressure reducer, thus avoiding repeated detachment and reattachment that causes wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter device is integrated into the high-pressure connector, then the filtering function is improved, but the device complexity increases and cleaning becomes complicated
Solution Approach 1:
The high-pressure connector is divided into two separable parts: a first connection side (connector body) and a second connection side (connector cap). The filter device is integrated into the connector cap, which can be easily separated from the connector body for independent cleaning and maintenance, thus reducing overall device complexity while maintaining the filtering function.
Solution Approach 2:
The filter device is extracted as a separate functional component integrated into the removable connector cap. This allows the filter to be accessed, cleaned, or replaced without disassembling the entire connector assembly, simplifying maintenance procedures while preserving the filtering capability.
2Ease of operation
If the entire high-pressure connector is detached for filter replacement, then the filter can be accessed, but wear on the connector increases and sealing functionality deteriorates
Solution Approach 1:
The connector is segmented into a permanent connector body and a removable connector cap. Only the cap containing the filter needs to be detached for filter maintenance, while the connector body remains attached to the breathing gas source. This minimizes wear on the main sealing interfaces and preserves sealing functionality.
Solution Approach 2:
The connector cap is pre-configured with the filter device and designed to be easily detachable. This preliminary design allows filter access without requiring complete connector disassembly, reducing the frequency and extent of detachments that cause wear and sealing degradation.
3Ease of repair
If the high-pressure connector is repeatedly detached and reattached, then filter maintenance is possible, but wear is markedly increased
Solution Approach 1:
By segmenting the connector into a permanent body and a removable cap, filter maintenance only requires detaching the cap, not the entire connector. This reduces the number of times the main connector assembly is subjected to detachment stress, thereby extending its operational lifespan.
Solution Approach 2:
The connector cap with the filter is designed as a replaceable component that can be easily detached and replaced. This allows the filter-containing cap to be maintained or replaced independently, while the expensive connector body remains in use, effectively extending the overall system lifespan.
4Reliability
If a plastic deformation is used for sealing, then sealing functionality is achieved, but the sealing cannot be reversibly restored after multiple detachments
Solution Approach 1:
The sealing function is separated into two parts: a permanent sealing interface between the connector body and breathing gas source, and a removable sealing interface on the connector cap. The permanent seal avoids repeated plastic deformation, while the removable cap seal can be easily replaced if needed, maintaining both reliability and adaptability.
