Solution Overview

Problem

Existing nasal dispensing devices often lead to incorrect usage, resulting in the nasal spray jet being directed vertically rather than horizontally, which is medically advantageous, and users struggle to insert the nasal olive correctly into the nostril.

Innovation Solution

A dispensing device with a vertically aligned contact surface and a stationary nasal olive that rises above it, ensuring intuitive user alignment and preventing undesirable orientations, allowing for easy and secure horizontal insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the discharge device is designed with a conventional nosepiece extending from the base body, then the device structure is simple, but the discharge direction becomes vertical which is medically disadvantageous

Engineering Contradiction:
Improvedevice structure simplicityVSAvoiddischarge direction correctness
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies preliminary anti-action by designing the nosepiece to protrude perpendicularly from the contact surface, pre-preventing the common user error of vertical discharge. The geometric configuration inherently guides correct horizontal insertion into the nostril, countering the natural tendency to hold the device vertically before the user even uses it.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The nosepiece is designed with an asymmetric configuration where it protrudes perpendicularly from the contact surface rather than extending along the main body axis. This asymmetric geometry creates an intuitive and physically constrained insertion path that naturally achieves the medically correct horizontal discharge direction.

Inventive Principle:
Principle #4Asymmetry

2Ease of operation

If the discharge opening is positioned at an angle of 90° to the main direction of extension, then the spray jet can be aligned horizontally, but it becomes difficult for the user to estimate the correct insertion depth

Engineering Contradiction:
Improvespray jet alignmentVSAvoidinsertion depth feedback
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies self-service by designing the nosepiece to protrude perpendicularly from the contact surface, allowing the device itself to provide intuitive insertion guidance. The geometric configuration and contact surface design work together to naturally guide the user to the correct insertion depth without requiring additional markings or complex feedback mechanisms.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the nasal olive is made stationary with respect to the main body, then the position is stable during use, but the device cannot be adjusted to different orientations

Engineering Contradiction:
Improvenasal olive position stabilityVSAvoidorientation adjustment capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent inverts the conventional approach by making the nosepiece stationary and protruding perpendicularly from the contact surface, rather than making it adjustable or movable. This inverted design achieves stability while the perpendicular geometry inherently provides the correct orientation guidance, making adjustment mechanisms unnecessary.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

The discharging device (10) has a main body (A), which has a contact surface (10b) that is turned and aligned vertically using a face of a user. A nose olive (70) is arranged stationarily to the main body for inserting into a nostril of the user. The nose olive is provided at an upper boundary region of the contact surface. The nose olive is collected over the contact surface, and has discharge opening (72).
