Solution Overview

Problem

Conventional nasal irrigation devices are not ergonomically convenient, require users to tilt their head, and lack control over fluid flow and pressure, making them unsuitable for home use, especially for individuals with medical conditions or varying nasal configurations.

Innovation Solution

A nasal irrigation device with an adjustable nozzle and a container that allows for vertical use, featuring a ball-and-socket coupling and angle limiter to maintain fluid flow at any desired angle, ensuring effective sinus penetration and coverage without tilting the user's head.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional nasal irrigation devices are used, then nasal irrigation can be performed, but the user must tilt their head which is inconvenient and uncomfortable

Engineering Contradiction:

Improveuser convenienceVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The device employs a ball-and-socket coupling mechanism that allows the dispenser to rotate and adjust to any inclined position within an allowable angle range. This dynamic adjustment capability enables the user to maintain a vertical head position while the dispenser adapts to the optimal irrigation angle, eliminating the need for head tilting.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention introduces rotational freedom in a third dimension through the ball-and-socket coupling. Instead of constraining the dispenser to a fixed orientation, the coupling allows rotation around a longitudinal axis, adding a rotational degree of freedom that enables vertical head positioning while maintaining proper fluid flow orientation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If conventional nasal irrigation devices are used, then nasal irrigation can be performed, but control over fluid flow and pressure is insufficient causing splashing or overflow

Engineering Contradiction:

Improvefluid flow controlVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device incorporates an angle limiter that constrains the dispenser's inclination within a specific range, optimizing fluid flow parameters. By limiting the angle of inclination, the system maintains reliable fluid flow control and prevents splashing or overflow while still allowing sufficient adjustment for different nasal configurations.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If conventional nasal irrigation devices are used, then nasal irrigation can be performed, but they are not suitable for users with certain medical conditions or varying nasal configurations

Engineering Contradiction:

Improvenasal configuration adaptabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ball-and-socket coupling provides dynamic adjustability that accommodates varying nasal configurations. The dispenser can be rotated to different angles within the allowable range, enabling adaptation to individual anatomical differences and medical conditions without requiring multiple specialized devices.

Inventive Principle:

Principle #15Dynamics
