Solution Overview

Problem

Current medical devices for diagnosing and rehabilitating oral and nasal breathing are inadequate in adapting to different examination types and patient morphologies, failing to effectively assess nasal breathing anomalies, velopharyngeal insufficiency, and orthopedic effects of maxillary expansion.

Innovation Solution

A modular apparatus with interchangeable removable heads of varying sizes, equipped with airflow sensors and a processing unit, allowing for simultaneous measurement of nasal and oral airflow, and capable of adapting to different patient morphologies through interchangeable components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed design of breathing measurement device is used, then the device structure is simple, but it cannot adapt to different patient morphologies and examination types

Engineering Contradiction:
Improveadaptability to different patient morphologiesVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into modular components: a handle unit and interchangeable head units. Each head unit can be detached and replaced with another of different size or configuration, allowing adaptation to different patient morphologies (adults, children, infants) without redesigning the entire device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handle unit serves multiple functions: it houses the control unit, displays measurement results, provides power supply, and accommodates different head units. This universal design allows one handle to work with various head configurations for different examination types and patient groups.

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

2Adaptability or versatility

If multiple specialized devices are used for different examination types, then each device can be optimized for its specific function, but the overall system complexity and cost increase

Engineering Contradiction:
Improvecapability for different examination typesVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses a universal handle unit that can accommodate different head units designed for specific examination types (orthodontic diagnosis, speech therapy, sleep disorders). This allows one device to perform multiple specialized functions that would otherwise require separate devices.

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

Solution Approach 2:

The system configuration is dynamically adaptable through interchangeable head units. The device can be reconfigured between examinations by simply swapping head units, allowing the system to optimize its structure for each specific examination type while maintaining a single core platform.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If conventional breathing sensors are used, then the device is simple, but it cannot provide accurate measurements of velopharyngeal insufficiency and nasal breathing anomalies

Engineering Contradiction:
Improveaccuracy of breathing measurementVSAvoidsensor system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple sensor types are integrated within the head unit: thermal sensors for temperature-based airflow detection, acoustic sensors for sound-based breathing analysis, and pressure sensors. This combination of sensors working together enables accurate measurement of complex breathing patterns including velopharyngeal insufficiency and nasal anomalies.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The head unit acts as an intermediary between the patient's breathing and the measurement system. It contains the sensor array and preliminary processing electronics, converting complex breathing signals into measurable parameters before transmission to the handle unit for analysis and display.

Inventive Principle:
Principle #24Intermediary (Mediator)
