Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation masks for premature babies and small children are complex to use due to the need for individual lung volume determination for oxygen adaptation and are prone to losing fit when the patient moves, leading to inefficient gas flow and potential lack of oxygen.
Innovation Solution
A multi-part ventilation mask with a soft, elastic nasal connection element and a rigid, rotatable coupling element that maintains a secure fit and minimizes stale air inhalation, featuring a Y-shaped hose connection element with inner partitions and a latching mechanism to ensure draught-free gas flow and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection structure is used between the ventilation mask and hoses, then structural stability is improved, but the mask loses fit when the patient moves
Solution Approach 1:
The connection system is divided into separate modular components: a nasal connection element, a hose connection element, and a coupling element. This segmentation allows each component to independently perform its function - the nasal element maintains seal through elasticity while the hose connection maintains structural stability through rigid coupling, resolving the contradiction between stability and fit security.
Solution Approach 2:
The hose connection element is designed with rotational capability relative to the coupling element, allowing dynamic adjustment. This rotational degree of freedom enables the system to adapt to patient movement while maintaining both structural stability through the rigid coupling and secure fit through the elastic nasal element, eliminating the need for rigid fixed connections.
2Stability of the object's composition
If the connection area and hoses are rigidly connected, then structural stability is improved, but the mask cannot adapt to patient movement
Solution Approach 1:
The hose connection element incorporates a rotational joint that allows it to move relative to the coupling element. This dynamic capability enables the system to adapt to patient movement in multiple directions while maintaining structural stability through the rigid coupling between the nasal element and hose connection element, eliminating the need for complete rigidity.
Solution Approach 2:
Different parts of the connection system have different mechanical properties: the nasal connection element uses elastic material for adaptability to facial contours, while the hose connection element uses rigid material for structural stability. The rotational joint provides localized flexibility where needed, allowing the system to simultaneously achieve both adaptability and stability without compromising either aspect.
3Adaptability or versatility
If a multi-part design with rotatable coupling is used, then adaptability to patient movement is improved, but device complexity increases
Solution Approach 1:
The connection system is divided into three main components: nasal connection element, hose connection element, and coupling element. Each component is relatively simple in design, and the modular architecture allows for easy assembly and disassembly. The rotatable joint is integrated into the coupling element, adding minimal complexity while providing significant adaptability benefits.
4Reliability
If the nasal connection element is made elastic, then fit security is improved, but manufacturing precision requirements increase
Solution Approach 1:
The material properties of the nasal connection element are optimized by selecting elastic materials with appropriate durometer ranges. This parameter selection allows the element to deform and conform to various facial shapes while maintaining reliable sealing. The elastic properties enable the element to accommodate manufacturing variations without requiring extremely tight tolerances, thus reducing manufacturing precision requirements while maintaining fit security.
