Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulizers lack efficient mechanisms for ensuring consistent particle size and automatic shut-off when the medicinal liquid is depleted, which can lead to inefficiencies and user errors.
Innovation Solution
A portable nebulizer with a vertical-type medicine containing and nebulizing assembly that includes a medicine storage module, a nebulizing module, and an induction module. The induction module uses metal induction elements and conductive structures to transmit signals from the nebulizing device to a microprocessor, enabling automatic shut-off when the liquid volume is insufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional nebulizer without induction module is used, then the device structure is simple, but the nebulizer cannot automatically shut off when liquid is depleted and may produce inconsistent particle sizes
Solution Approach 1:
The induction module includes metal induction elements that detect the liquid level and provide feedback signals to the control module. When the liquid level drops below the induction elements, the control module automatically shuts off the nebulizing device, ensuring reliable automatic shut-off functionality.
Solution Approach 2:
The patent replaces complex mechanical level detection mechanisms with an induction-based detection system. The metal induction elements interact with the liquid to generate electrical signals, eliminating the need for mechanical float indicators or contact-based switches, thus achieving automatic shut-off with simpler overall structure.
2Manufacturing precision
If no induction module is present, then the device is easier to manufacture, but particle size consistency cannot be ensured
Solution Approach 1:
The induction module provides real-time feedback on liquid level and flow conditions to the control module, which adjusts the nebulizing parameters accordingly. This feedback mechanism ensures consistent particle size by maintaining optimal liquid supply conditions during nebulization.
Solution Approach 2:
The control module uses signals from the induction module to dynamically adjust nebulization parameters such as ultrasonic power or pneumatic pressure. This parameter adjustment ensures consistent aerosol particle sizes even as liquid level changes during operation.
3Productivity
If manual monitoring of liquid level is required, then fewer components are needed, but user errors and inefficiencies increase
Solution Approach 1:
The nebulizer system performs self-monitoring of liquid levels through the induction module and automatically shuts off when liquid is depleted. This self-service capability eliminates the need for user intervention, preventing user errors and improving operational efficiency.
Solution Approach 2:
The induction module continuously monitors liquid levels and provides feedback to the control module, which automatically manages the nebulization process. This automated feedback loop eliminates manual monitoring requirements and improves productivity by preventing operational errors.
4Measurement precision
If metal induction elements are exposed on the inner surrounding area, then liquid level detection is improved, but the risk of signal interference increases
Solution Approach 1:
The induction module uses the liquid itself as an intermediary medium between the metal induction elements and the control module. The liquid's electrical properties enable level detection while the sealed structure of the induction module protects the metal elements from direct exposure to the nebulization environment, reducing signal interference risks.
Solution Approach 2:
The induction module likely employs sealed enclosures or protective films around the metal induction elements while allowing electrical interaction with the liquid. This protective barrier prevents corrosion and signal interference from environmental factors while maintaining detection accuracy.
