Nebulizer Container Securing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulizers face challenges in providing a simple and cost-effective construction for securely holding a pre-installed container that is movable during fluid conveyance and nebulization, while preventing undesired opening and separation from the housing.
Innovation Solution
A nebulizer design incorporating a securing means, such as a metal or stamping part, that holds the container inseparably within the housing, allowing it to move back and forth during operation, and forms a transportation lock to keep the container unmoveable in the delivery state, thereby simplifying assembly and preventing incorrect handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a securing means is used to hold the container inseparably in the housing, then the container is prevented from separation and misinsertion, but the device complexity increases
Solution Approach 1:
The securing means combines multiple functions into a single integrated component: it simultaneously secures the container against separation, prevents misinsertion through directional engagement, and forms a transportation lock to hold the container unmoveably in the delivery state. This merging of functions reduces the number of separate parts needed while maintaining comprehensive container security.
Solution Approach 2:
The securing means is designed as a multi-functional element that performs several roles: it acts as a mechanical connector between container and housing, provides a transportation lock mechanism, enables movable engagement during operation, and prevents incorrect insertion. This multi-functionality addresses the reliability requirement without proportionally increasing device complexity.
2Ease of operation
If the container is made movable during operation, then fluid conveyance and nebulization are enabled, but the container may be accidentally separated from the housing
Solution Approach 1:
The securing means transitions from a static locked state during transportation to a dynamic movable state during operation. The design allows the container to move back and forth within the housing when engaged, enabling fluid conveyance and nebulization functions while maintaining secure connection through the directional engagement features of the securing means.
Solution Approach 2:
The securing means separates the transportation function from the operation function through distinct engagement mechanisms: a locked configuration for secure transportation and a movable configuration for operational fluid conveyance. This segmentation allows each function to be optimized independently while using a single integrated component.
3Reliability
If a transportation lock is formed to hold the container unmoveably in delivery state, then misinsertion and misuse are prevented, but the assembly complexity increases
Solution Approach 1:
The transportation lock is integrated into the securing means as a combined feature rather than a separate mechanism. The securing means simultaneously provides the mechanical connection between container and housing and incorporates the transportation lock functionality, eliminating the need for additional separate locking components and simplifying the manufacturing process.
Solution Approach 2:
The securing means serves multiple purposes: it acts as the primary connection element, forms the transportation lock mechanism, and enables operational movement. This multi-functionality reduces the total number of parts and assembly steps compared to using separate dedicated components for each function.

AI summary
A nebulizer is proposed which includes an insertable container and a securing mechanism for holding the container in the nebulizer such that the container can move back and forth but can not be separated. The securing mechanism is formed by a metal unitary part. The securing mechanism forms a transportation lock for holding the container unmovable in the housing in a delivery state of the nebulizer. The securing mechanism forms a ring with flexible holding fingers.
