Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic aromatic sprays require a large instantaneous pressing force to atomize the fluid, resulting in incomplete atomization with small liquid droplets due to insufficient force from the eccentric cam arrangement, leading to inefficient spraying.
Innovation Solution
A disposable gas diffusion device that uses a gas supply device with a compression element and a diffuser system to create a negative pressure zone, inducing a high conveyance speed of liquid through a liquid guiding device to an atomization hole, where the liquid is sprayed into a mist and discharged through an exit opening, achieving effective atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an eccentric cam arrangement is used to depress the nozzle, then the device structure is simple, but the instantaneous pressing force is insufficient to achieve complete atomization
Solution Approach 1:
The patent replaces the mechanical eccentric cam system with a pneumatic compression system. A compression element is actuated by pressurized gas from a gas supply device to directly depress the nozzle, substituting mechanical cam-based force generation with a pneumatic actuation system that delivers higher instantaneous force for complete atomization
Solution Approach 2:
The invention introduces a gas supply device that delivers pressurized gas to a compression element, using pneumatic pressure to generate the force needed to depress the nozzle. This pneumatic system overcomes the force limitations of the mechanical cam arrangement while enabling complete atomization of the aromatic fluid
2Manufacturing precision
If a large instantaneous pressing force is applied to atomize the fluid, then complete atomization is achieved, but the device complexity increases
Solution Approach 1:
The gas supply device serves multiple functions: it provides pressurized gas to the compression element for nozzle actuation, creates negative pressure zones for liquid conveyance, and enables automatic atomization control. This multi-functional component achieves complete atomization without proportionally increasing overall device complexity
Solution Approach 2:
The system achieves automatic operation where the pressurized gas flow automatically creates the negative pressure zone that draws liquid to the nozzle, and the compression element automatically actuates the nozzle when sufficient pressure is reached. This self-service mechanism eliminates the need for complex external control systems while ensuring complete atomization
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 ensures complete atomization of the liquid into a fine mist, improving convenience and effectiveness of spraying, with the gas supply device controlling flow rate and time intervals to ensure efficient and wide coverage of the atomized liquid.
Implementation Method 1
introduce a pressurized gas from a gas supply device into a container and induces a negative pressure zone inside the container so that through an operation based on high/low pressures, a liquid is conducted and conveyed
Implementation Method 2
the liquid, when passing though the atomization hole, is immediately sprayed out to form a mist and the atomized liquid is discharged through an exit opening
