Solution Overview

Problem

Nasal distribution devices face challenges in accommodating varying nostril sizes, leading to inefficient dose distribution and increased manufacturing costs due to the need for multiple removable tips of different sizes.

Innovation Solution

A nasal distribution head with a tip that axially moves between two offset positions, utilizing a hollow cylindrical sleeve and radial projections to define insertion depth and orientation, allowing for adjustable fit without requiring multiple tip sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple removable tips of different sizes are provided to accommodate varying nostril dimensions, then the adaptability to different users is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improveadaptability to different nostril sizesVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tip is made axially movable on the head between at least two positions of use axially offset from one another. The tip can be positioned at different axial locations to accommodate different nostril sizes, eliminating the need for multiple removable tips of different sizes while maintaining adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A single tip structure serves multiple functions by being axially movable between different positions. This single tip can adapt to various nostril dimensions through axial movement, making the device universal for different users without requiring multiple specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple removable tips of different sizes are provided, then the adaptability to different users is improved, but the manufacturing cost increases

Engineering Contradiction:

Improveadaptability to different nostril sizesVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Multiple tip sizes are merged into a single tip structure that can be axially positioned at different locations. This consolidation reduces the number of separate components from multiple to one, thereby reducing manufacturing cost while preserving the ability to accommodate different users.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the tip is made axially movable between different positions, then the adaptability to different nostril sizes is improved, but the device complexity increases

Engineering Contradiction:

Improveadaptability to different nostril sizesVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The tip structure is segmented with a hollow cylindrical axial sleeve arranged around a cylindrical portion of the head, with radial flanges and radial projections that enable axial movement. This segmentation allows the tip to be positioned at different axial locations while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

4Reliability

If the tip structure includes radial flanges and radial projections for axial movement control, then the reliability of dose distribution is improved, but the device complexity increases
