Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes face issues such as unsanitary tobacco tar injection, reduced smoke quantity, high replacement costs, and poor user experience due to direct contact between tobacco tar and components, which affects the quality and convenience of the smoking experience.
Innovation Solution
A disposable cigarette cartridge design featuring a replaceable tobacco tar guide body and ultrasonic atomizing sheet, with a tower-shaped spring structure to block tobacco tar beads and enhance airflow, ensuring better contact with the atomizing surface and preventing tar wastage, while allowing for independent component replacement and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the tobacco tar cavity is arranged in the shell and is in direct contact with the inner wall of the shell, then the structure is simple, but microorganisms such as bacteria or impurities are inevitably brought into the atomizer in a tobacco tar injection process, the quality guarantee period of the tobacco tar is shortened or the smoke taste is affected
Solution Approach 1:
The invention divides the atomizer into separable components: a removable tobacco tar guide body that can be detached from the shell. This segmentation allows the tobacco tar cavity to be isolated during injection, preventing contamination while maintaining simple overall structure. The tobacco tar guide body includes a tobacco tar cavity that can be independently handled during the injection process.
Solution Approach 2:
The tobacco tar guide body acts as an intermediary component between the shell and the atomizing elements. It provides a controlled interface for tobacco tar injection through the injection hole, preventing direct contact between external contaminants and the internal tobacco tar storage environment, thus extending quality guarantee period.
2Ease of operation
If the air pressure generated during the normal operation of an ultrasonic atomizing sheet will rush a tobacco tar guide body which is used for guiding the tobacco tar away from the surface of the ultrasonic atomizing sheet, then the tobacco tar can be guided away, but the atomization effect is affected, so that the amount of smoke is small
Solution Approach 1:
The tobacco tar guide body features localized structural variations: the first portion has a different cross-sectional shape than the second portion, creating different flow characteristics at different locations. The inner wall includes specific guiding structures that direct tobacco tar flow in certain regions while allowing vapor to pass through in other regions, optimizing both guiding function and atomization efficiency.
Solution Approach 2:
The tower-shaped spring structure and the curved pathways within the tobacco tar guide body utilize spiral and curved geometries to manage airflow and tobacco tar movement. The spiral spring structure specifically helps to stabilize the flow while preventing direct rush of air pressure that would disrupt atomization.
3Power
If the cavitation effect generated during the normal operation of the ultrasonic atomizing sheet generates a high temperature, then the atomization process is active, but it is liable to cause carbonization damage to the tobacco tar guide body
Solution Approach 1:
The tobacco tar guide body is designed as a disposable or easily replaceable component. Made from materials that can withstand high temperatures during the atomization process, it is intended to be replaced periodically rather than maintained, eliminating the need for complex repair systems and ensuring consistent performance throughout its service life.
4Device complexity
If the existing tobacco tar guide body, the tobacco tar storage device and the ultrasonic atomizing sheet are made into an entirety and cannot be randomly changed, then the assembly is simple, but the entirety needs to be changed once a certain component is damaged, so that the use cost is high
Solution Approach 1:
The atomizer is segmented into independently replaceable components: the tobacco tar guide body, the ultrasonic atomizing sheet, and the tobacco tar storage device. Each component can be removed and replaced separately through designed interfaces, allowing users to replace only the damaged or depleted component rather than the entire assembly, thus reducing replacement costs and simplifying maintenance.
5Device complexity
If the atomizing surface of the ultrasonic atomizing sheet is in contact with the tobacco tar guide body, and the tobacco tar guide body is directly communicated with a suction nozzle, then the structure is compact, but the tobacco tar beads are directly sprayed onto the mouth of the user along an air outlet passage, so that the tobacco tar is wasted, and the user experience is poor
Solution Approach 1:
The tobacco tar guide body serves as an intermediary structure between the atomizing surface and the suction nozzle. It includes a tobacco tar cavity and guiding passages that redirect the flow, allowing vapor to pass through to the user while intercepting and redirecting tobacco tar beads away from the direct path to the mouth, preventing wastage and improving user experience.
Solution Approach 2:
The tower-shaped spring structure and the multi-dimensional pathways within the tobacco tar guide body utilize three-dimensional spatial arrangement to separate the trajectories of vapor and tobacco tar beads. By creating vertical and horizontal flow paths, the design allows vapor to reach the user while tobacco tar beads are redirected along different spatial routes, preventing direct contact with the user's mouth.
