Reusable Indicator Device for Nebulizer Container Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulizers require the replacement of housing parts along with containers, which complicates operation and increases the size of replacement packages, making them less convenient and more cumbersome for handling and transport.
Innovation Solution
A nebulizer design where the indicator device is integrated with the container and can be reused with a new container, allowing for secure and easy operation without the need to replace any housing parts, with a mechanical coupling that enables the indicator device to control the locking mechanism, ensuring that only the container and indicator device need to be replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the indicator device is integrated with the housing part and replaced together with the container, then the locking mechanism is simplified, but the replacement package size increases and handling becomes more cumbersome
Solution Approach 1:
The system is divided into separate functional modules: the indicator device remains integrated with the housing part and is reused, while only the container is replaced. This segmentation allows the locking mechanism to remain simple without increasing replacement package size, as the indicator device is not included in the replaceable unit.
Solution Approach 2:
The housing part with the integrated indicator device serves multiple functions: it provides structural housing, contains the indicator mechanism for tracking container usage, and maintains the locking function. This multi-functionality eliminates the need to replace the housing part with each container, reducing replacement package size while maintaining system complexity.
2Volume of moving object
If the indicator device is integrated with the container and reused with new containers, then replacement package size is reduced, but the control mechanism becomes more complex
Solution Approach 1:
The indicator device is extracted from the container and left integrated with the housing part. This extraction simplifies the replacement process (only the container needs to be replaced) while the control mechanism complexity is managed by maintaining the indicator device as a separate, reusable component within the housing.
3Reliability
If the nebulizer requires replacement of housing parts along with containers, then the locking and securing mechanism is simplified, but operation becomes less convenient and handling more cumbersome
Solution Approach 1:
The system is segmented so that only the container is replaced while the housing part with the integrated indicator device remains in place. This segmentation maintains the reliability of the locking mechanism (which remains with the housing) while significantly improving ease of operation, as users only need to replace the small container rather than the entire housing assembly.
4Measurement precision
If the indicator device counts and controls locking for each container separately, then container-specific tracking is improved, but the overall system complexity increases
Solution Approach 1:
The indicator device integrated in the housing part serves as a universal tracking mechanism that works with multiple containers over time. It maintains precise container-specific tracking by resetting or reinitializing for each new container while remaining physically integrated with the housing, thus avoiding the need for separate indicator devices with each container and reducing overall system complexity.

AI summary
A nebulizer (1) comprises a replaceable container (3) with fluid (2) to be nebulized. The container comprises an inseparable indicator device (25). The container and the indicator device are axially moved during nebulization and tensioning of the nebulizer. The indicator device controls locking of the nebulizer against further use if a predetermined number of uses has been reached or exceeded.
