Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPAP ventilation devices lack advanced features for user interaction and feedback, such as real-time respiratory and heart rate monitoring, and do not provide effective alarm mechanisms for potential issues like mask removal during use.
Innovation Solution
A respiratory ventilation device with integrated light sources that modulate intensity and color based on airflow and pressure sensors, providing visual feedback and alarm sequences to adjust user breathing and detect mask removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light sources are added to provide visual feedback and alarm functions, then user interaction and monitoring capabilities are improved, but device complexity increases
Solution Approach 1:
The light sources serve multiple functions: providing visual feedback for respiratory rate, indicating alarm conditions for mask removal, and potentially guiding user breathing. This multi-functionality addresses the technical contradiction by improving adaptability and versatility without proportionally increasing device complexity, as a single component (light sources) performs multiple monitoring and interaction tasks.
2Ease of operation
If light sources are integrated into the device housing, then visual feedback is provided without adding external components, but the housing material must be translucent which may affect structural integrity
Solution Approach 1:
The housing material has different properties in different locations: translucent in areas where light sources are integrated to provide visual feedback, and potentially more opaque or reinforced in areas requiring higher structural integrity. This local differentiation resolves the contradiction by providing visual feedback where needed while maintaining overall structural strength.

AI summary
A respiratory ventilation device—configured to send an airflow, generated by a fan, into a duct that extends between the device and a breathing mask configured to be worn by a user—comprises an air inlet intended to admit air into the device; a fan; and an air outlet configured to be connected to the duct, such that, when the fan is in operation, the air flows from the air inlet successively toward the fan and then toward the air outlet. The device also comprises a flow rate sensor configured to measure a flow rate of air circulating through the device, and/or a pressure sensor configured to measure a pressure between the fan and the air outlet. A control unit is connected to the flow rate sensor and/or to the pressure sensor. The device also includes at least one source of light.
