Respiratory Mask Guide Region for Easy Secure Harness Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Respiratory masks for ventilation or respiratory assistance often require complex coupling mechanisms that demand high dexterity for secure fitting, posing challenges for users, especially in home settings.
Innovation Solution
A respiratory mask design featuring a face part with a plane of symmetry, circumferential seal, and guide regions in the form of depressions or elevations that facilitate easy and secure attachment of a harness through anchor points with receiving elements and connection elements, guided by a guide groove that enhances user-friendly fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex coupling mechanisms are used to secure the respiratory mask, then the stability and security of fitting is improved, but the ease of operation deteriorates due to high dexterity requirements
Solution Approach 1:
The coupling mechanism is divided into separate components: a connection element with connection portion and extension portion, and a receiving element with receiving opening. This segmentation allows the user to easily align and connect the parts without requiring complex manipulation, while still achieving secure attachment.
Solution Approach 2:
The guide region acts as an intermediary feature that facilitates the connection between the connection element and receiving element. The guide groove provides a tactile path that guides the connection portion into the receiving opening, making the coupling process intuitive and easy to perform correctly.
2Stability of the object's composition
If multiple coupling points are used to secure the harness, then the stability of the respiratory mask is improved, but the device complexity increases
Solution Approach 1:
The complex multi-point coupling system is extracted and replaced with a simplified anchor point system. Each anchor point contains a receiving element that can be easily connected to the harness, reducing the overall coupling complexity while maintaining stability through multiple distributed anchor points.
Solution Approach 2:
The coupling mechanism uses geometric parameter design - the receiving opening is sized to fit the connection portion with appropriate clearance, and the guide groove dimensions are optimized to guide alignment. These parameter optimizations enable simple yet effective coupling without requiring complex mechanisms.
