Solution Overview

Problem

Existing nasal product distribution systems face challenges in stabilizing the position of the dispensing device relative to the user's nose, particularly for targeting hard-to-reach areas like the olfactory zone, due to variability in ear-mounted mobile devices affecting the device's orientation and repeatability.

Innovation Solution

A control system with a first support attached to the dispensing device and a second support fixed to the user's forehead or nose, utilizing orientation sensors to determine the relative orientation between the two, ensuring a predetermined alignment with the sagittal or frontal planes of the head, thereby stabilizing the dispensing device's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mobile device is attached to the user's ear, then the device can be portable and easy to use, but the positioning stability and repeatability deteriorate due to ear dimension variability

Engineering Contradiction:
ImproveportabilityVSAvoidpositioning stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a head-mounted support structure as an intermediary between the user's head and the mobile device. This support structure serves as a stable platform that maintains a consistent spatial relationship with the nasal cavity, eliminating the positioning variability caused by direct ear attachment while preserving portability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a virtual reference frame through the head-mounted support structure that replicates a stable anatomical reference point on the user's head. This virtual reference copies the stability of fixed anatomical landmarks without requiring direct attachment to those landmarks, thereby maintaining positioning reliability across different users and usage scenarios.

Inventive Principle:
Principle #26Copying

2Ease of operation

If the mobile device position varies from one use to another, then user comfort and ease of attachment are improved, but the positioning precision and product distribution accuracy deteriorate

Engineering Contradiction:
Improveease of attachmentVSAvoidpositioning precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent performs preliminary positioning action by establishing the head-mounted support structure before device attachment. This support structure pre-establishes a stable reference frame that ensures consistent spatial alignment between the mobile device and the nasal cavity, guaranteeing positioning precision while maintaining ease of attachment through a simple head-mounted configuration.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the dispensing device is not positioned at optimal angles, then ease of use is improved, but the product distribution effectiveness to target areas deteriorates

Engineering Contradiction:
Improveease of useVSAvoidproduct distribution effectiveness
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements feedback through the orientation sensor that continuously monitors the dispensing device's angular position relative to the nasal cavity. This feedback information is processed to determine whether the device is positioned at optimal angles for effective product delivery to target areas such as the olfactory zone, enabling real-time adjustment while maintaining ease of use through automated guidance.

Inventive Principle:
Principle #23Feedback
