Innovation Solution

A wearable inhalation delivery device integrated into a mask with a nasal pillow and mouthpiece, featuring air pressure sensors, microprocessors, and ultrasonic piezoelectric transducers, which activate upon inhalation to control the delivery of fluids such as aerosols, vapors, or oxygen gases, ensuring comfortable and precise inhalation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a wearable inhalation delivery device is integrated into a mask, then the ability to deliver fluids (aerosol, vapor, mist, oxygen gas) to the wearer's air passages is improved, but the device complexity increases

Engineering Contradiction:
Improvefluid delivery capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single wearable mask device: air filtration through particulate filters, inhalation detection via air pressure sensors, and controlled fluid delivery through vaporizing nozzles or ultrasonic transducers. This integration allows the mask to simultaneously protect against pollution while delivering therapeutic fluids, resolving the contradiction by merging previously separate functions into one unified system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mask is designed as a multi-functional device that can perform air filtration, inhalation detection, and various fluid delivery modes (vaporization, ultrasonic mist generation, oxygen delivery). The microprocessor controls different delivery mechanisms based on detected inhalation patterns, making the device universally applicable for multiple respiratory needs while maintaining a single wearable form factor.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If air pressure sensors and microprocessors are added to control fluid delivery, then the precision of inhalation delivery is improved, but the device complexity increases

Engineering Contradiction:
Improveinhalation detection precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The device incorporates air pressure sensors that detect inhalation events and provide feedback to a microprocessor. The microprocessor analyzes the inhalation signal and triggers fluid delivery only when inhalation is detected, creating a closed-loop feedback system. This ensures precise delivery timing synchronized with the wearer's natural inhalation cycles, improving measurement precision while using electronic control to manage the added complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically detects inhalation events and triggers fluid delivery without requiring manual activation. The air pressure sensor continuously monitors for inhalation patterns, and the microprocessor autonomously controls the vaporizing nozzle or ultrasonic transducer based on detected inhalation, making the device self-regulating and reducing the need for user intervention despite the added electronic components.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a nasal pillow and mouthpiece are integrated into the mask, then the comfort and normal breathing capability are improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mask is divided into distinct functional sections: a nasal pillow section for nasal inhalation delivery, a mouthpiece section for oral inhalation delivery, and filtration sections. Each component is optimized for its specific function, allowing the wearer to breathe naturally through preferred pathways while the device delivers fluid to the appropriate air passages. This segmentation improves comfort by accommodating natural breathing patterns while organizing complexity into manageable separate components.
