Solution Overview

Problem

Existing devices fail to effectively improve nasal ventilation, particularly in children, by making nasal breathing a habitual pattern, and lack the ability to measure airflow rates suitable for nasal ventilation, leading to suboptimal air conditioning and potential health issues such as reduced IQ and sinus hypopneumatization.

Innovation Solution

A device comprising a sealing element and cannula system that allows for maximum airflow from one nostril, with a silicone lancehead-shaped sealing element and a telescopic cannula for efficient air delivery and a flow rate measurement system using a ping-pong ball or flow meter to track improvements in nasal ventilation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a device is designed to measure maximum nasal airflow rates, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveairflow rate measurementVSAvoiddevice structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

A movable body (ping-pong ball) is introduced as an intermediary element that translates airflow rate into visible displacement. The ball's movement through a graduated channel provides measurement capability without requiring complex electronic sensors or flow meters, thus maintaining measurement precision while minimizing device complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The device uses pneumatic pressure from the patient's exhaled air to move the ping-pong ball through a graduated channel. This pneumatic mechanism provides a simple, reliable way to measure and visualize airflow rate without electronic components, resolving the contradiction between measurement precision and device complexity

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Productivity

If a sealing element is inserted into the nostril to collect airflow, then airflow collection efficiency is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveairflow collection efficiencyVSAvoiddevice usability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The sealing element is made of flexible silicone material that can be easily inserted into and conform to the nostril shape. This flexibility improves sealing efficiency while maintaining ease of insertion and removal, resolving the contradiction between airflow collection efficiency and ease of operation

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The device is divided into separate, easily removable components including the sealing element, cannula, and measurement chamber. This segmentation allows the sealing element to be quickly inserted and removed without manipulating the entire device, improving both sealing efficiency and ease of operation

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the device is made simple and pleasant to use, then ease of operation is improved, but measurement precision may deteriorate

Engineering Contradiction:
Improveuser comfortVSAvoidairflow measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The ping-pong ball acts as a mechanical intermediary that provides accurate measurement through its displacement in a graduated channel. This simple visual measurement method maintains precision while keeping the device pleasant and stress-free to use, especially for children

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patient's own exhaled air provides the force to move the ping-pong ball, eliminating the need for external power sources or complex actuation mechanisms. This self-powered approach maintains measurement accuracy while keeping the device simple and comfortable to use

Inventive Principle:
Principle #25Self-service
