Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nebulization devices lack accurate control over liquid consumption during the nebulization process, leading to potential overdosing or underdosing, especially in medical applications, and existing disposable containers do not facilitate controlled consumption.
Innovation Solution
A constant quantity control nebulization device is designed with a fixing plate and rotary ring that form a first liquid storage space, featuring a seal film breaking structure and safety switches to ensure precise liquid control and prevent erroneous operation, allowing for accurate liquid consumption and improved user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional refilling method is used to supplement liquid, then the device can be continuously used, but the liquid consumption cannot be controlled accurately
Solution Approach 1:
The liquid storage system is segmented into a removable container and a fixed storage space within the main body. The container can be separately filled and replaced, while the fixed storage space provides precise measurement markings. This segmentation allows accurate consumption control through the fixed space while maintaining operational flexibility through the removable container.
Solution Approach 2:
The fixed storage space is pre-marked with measurement indications showing the required liquid volume before use. Users can preliminarily measure and transfer the exact required amount of liquid from the container to the fixed storage space, ensuring accurate consumption control before the nebulization process begins.
2Ease of operation
If disposable containers are used for liquid storage, then storage and carrying convenience is improved, but consumption control capability is lost
Solution Approach 1:
The system separates the disposable container function from the measurement and control function. The removable container provides portable storage convenience, while the fixed storage space with measurement markings provides precise consumption control. This segmentation allows each component to excel at its specific function.
Solution Approach 2:
The fixed storage space acts as an intermediary between the disposable container and the nebulization device. It receives liquid from the container, provides precise measurement and volume control, and then supplies the controlled liquid amount to the nebulization module, thereby enabling consumption control while maintaining the convenience of disposable containers.
3Adaptability or versatility
If rotary method is used for switching liquid supply, then operation flexibility is improved, but erroneous operation risk increases
Solution Approach 1:
The rotary ring is pre-designed with through holes positioned at specific angles corresponding to different liquid storage compartments. The ring can be rotated to predetermined positions where the through holes align with the corresponding compartments, ensuring that liquid supply switches to the correct compartment without risk of erroneous connection.
Solution Approach 2:
Different regions of the rotary ring have different functional characteristics - through holes are located only at specific angular positions to connect with specific compartments. This local differentiation ensures that rotation to a particular position activates a specific liquid supply path, providing flexible switching while preventing erroneous operation through geometric constraint.
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 device enables precise control over liquid consumption, enhancing the operational convenience and safety by ensuring the nebulization of a predetermined volume of liquid, thereby improving treatment efficacy and reducing the risk of overdose or underdose.
Implementation Method 1
The operation principle of the nebulization devices is to generate vibration energy by a piezoelectric device, and then transmit the vibration energy to a spray orifice plate through a conduction plate in order to nebulize the liquid passing through the spray orifice plate
