Solution Overview

Problem

Conventional medicament cartridges in nebulizers suffer from residual medicament wastage and contamination issues due to their design, which includes inside corners that trap liquid and are difficult to clean, leading to inefficient medicament delivery and potential bacterial growth.

Innovation Solution

A medicament storage module with an inclined bottom wall and tubular sidewall, featuring a guiding part such as a C-shaped curvy structure, eliminates inside corners and facilitates easy cleaning, ensuring efficient medicament delivery by reducing residual medicament and preventing contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a conventional medicament cartridge with a horizontal bottom wall and perpendicular lateral walls is used, then the structure is simple and easy to manufacture, but inside corners are formed that trap residual medicament and are difficult to clean

Engineering Contradiction:
Improvestructural simplicityVSAvoidcleanability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies curvature by replacing the conventional horizontal bottom wall with an inclined bottom wall that slopes downward toward the outlet. This curved/angled surface eliminates the formation of inside corners where medicament would otherwise be trapped, allowing complete drainage and easy cleaning while maintaining manufacturing simplicity

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Device complexity

If a conventional medicament cartridge with inside corners is used, then the structure is simple, but residual medicament is retained at the bottom and inside corners leading to wastage and contamination

Engineering Contradiction:
Improvestructural simplicityVSAvoidmedicament wastage
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The inclined bottom wall creates a slope that guides all residual medicament toward the outlet, eliminating dead zones and inside corners. This ensures complete medicament delivery without retention, preventing wastage while keeping the structure simple and easy to manufacture

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Device complexity

If a conventional medicament cartridge with inside corners is used, then the structure is simple, but the medicament is readily retained at dead zones causing contamination and bacteria growth

Engineering Contradiction:
Improvestructural simplicityVSAvoidbacterial contamination
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The inclined bottom wall eliminates inside corners and dead zones where medicament would be retained. By creating a continuous slope to the outlet, the design prevents stagnation of medicament, thereby eliminating the conditions necessary for bacterial growth and contamination while maintaining structural simplicity

Inventive Principle:
Principle #14Spheroidality (Curvature)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design effectively reduces residual medicament, enhances nebulizing efficiency, and prevents bacterial contamination, allowing for improved medicament delivery and user convenience by minimizing the nebulizer's size and weight while maintaining the required medicament capacity.

Implementation Method 1

The inclined bottom wall is inclined at an inclination angle with respect to a horizontal plane... the liquid medicament outputted from the outlet

AI summary

A nebulizer (2) includes a medicament storage module (3) and a nebulizing unit (4). The medicament storage module (3) includes an inclined bottom wall (31), a tubular sidewall (32), and a guiding part (35). The inclined bottom wall (31) is inclined at an inclination angle (θ1). The tubular sidewall (32) is connected with a periphery of the inclined bottom wall (31). A storage chamber (33) is defined by the inclined bottom wall (31) and the tubular sidewall (32) collaboratively, and a liquid medicament is accommodated within the storage chamber (33). The tubular sidewall (32) has an outlet (34), and the inclined bottom wall (31) is extended downwardly to the outlet (34). The guiding part (35) is arranged around a junction between the inclined bottom wall (31) and the tubular sidewall (32). The nebulizing unit (4) is disposed on the medicament storage module (3) and aligned with the outlet (34). The liquid medicament outputted from the outlet (34) is nebulized into a plurality of mist droplets by the nebulizing unit (4).
