Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory masks do not effectively check for leaks, which can allow pollutants to bypass the filter and reach the user, compromising protection.
Innovation Solution
An arrangement comprising a respiratory mask, an intermediate piece, and a pressure sensor that measures pressure at different connection points to ensure fluid-tight fit and functionality, allowing for various operational modes to test and maintain the mask's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a respiratory mask is used without an intermediate piece and direct connection, then the device complexity is reduced, but the ability to check for leaks and ensure fluid-tight fit deteriorates
Solution Approach 1:
The patent introduces an intermediate piece as a mediator component between the respiratory mask and the breathing air source. This intermediate piece includes a pressure sensor that enables leak detection and tightness checking without requiring complex integration into the mask itself. The intermediate piece acts as a bridge that adds testing functionality while keeping the mask design relatively simple.
2Reliability
If an intermediate piece with pressure sensor is added to check for leaks, then the reliability of fluid-tight fit is improved, but the device complexity increases
Solution Approach 1:
The patent segments the respiratory protection system into distinct functional modules: the respiratory mask, the intermediate piece with pressure sensor, and the breathing air source. This segmentation allows the leak detection functionality to be isolated in the intermediate piece, making it easier to manufacture, maintain, and replace without affecting the mask itself.
Solution Approach 2:
The intermediate piece serves as a mediator that adds measurement and control functionality to the system. By placing the pressure sensor in this intermediate component rather than integrating it directly into the mask or the air source, the patent distributes complexity across multiple components, each with a specific function.
3Ease of operation
If the breathing air source is connected directly to the respiratory mask without intermediate piece, then the ease of operation is improved, but the ability to perform leak detection and testing deteriorates
Solution Approach 1:
The intermediate piece with pressure sensor acts as a mediator that enables leak detection while maintaining operational simplicity. The pressure sensor automatically monitors the fluid connection, and the system can indicate leaks through visual or audible signals, making detection easy without requiring complex user intervention.
Solution Approach 2:
The pressure sensor in the intermediate piece enables self-monitoring of the fluid connection integrity. The system automatically detects leaks and can alert the user without requiring manual testing procedures, thus improving both leak detection capability and ease of operation.
4Adaptability or versatility
If multiple connection configurations are supported with intermediate piece, then the adaptability of the system is improved, but the device complexity increases
Solution Approach 1:
The intermediate piece is designed with universal coupling points that can connect to different types of respiratory masks and breathing air sources. The pressure sensor and coupling mechanism are designed to work with various configurations, enabling the same intermediate piece to serve multiple functions and adapt to different operational requirements.

Function Achieved in This Case
Ensures the respiratory mask fits snugly and functions correctly by detecting leaks and enabling efficient use with different breathing air sources, enhancing user safety and convenience.
Implementation Method 1
A pressure sensor in the arrangement is configured to measure the pressure at a measuring position. This measuring position is located in the fluid connection which the intermediate piece provides

AI summary
The disclosure relates to an arrangement with a breathing air source, a respiratory mask, and an intermediate piece, as well as to two methods for operating such an arrangement. A device-side coupling point of the intermediate piece can be connected to a coupling point of the breathing air source, a mask-side coupling point of the intermediate piece can be connected to a coupling point of the respiratory mask. If the intermediate piece is connected to the breathing air source (30) and to the respiratory mask, a fluid connection is established which leads from the breathing air source to the respiratory mask. A pressure sensor measures the pressure inside the intermediate piece. In addition, the breathing air source can be connected directly to the respiratory mask.
