Solution Overview
Problem
Current electronic cigarettes with electromagnetic heating face issues of complex structure, large size, and inefficient heating due to the use of induction coils connected by wires, leading to inaccurate temperature control and burnt flavor in the smoking vapor.
Innovation Solution
An electronic cigarette design featuring a hollow liquid conductor atomizer with a metallic net inner wall and a compact power supply unit, where the induction coil surrounds the power supply, eliminating the need for direct electrical connections and reducing the risk of tobacco liquid flow onto the control circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an induction coil connected by wire is used for electromagnetic heating, then heating efficiency is improved, but device complexity and size increase
Solution Approach 1:
The patent extracts and eliminates the connecting wire from the induction coil assembly, allowing the coil to be directly integrated into the atomizer structure. This removes the complex wiring while maintaining the electromagnetic heating function, thus improving heating efficiency without increasing device complexity.
Solution Approach 2:
The induction coil is merged with the atomizer structure, where the coil becomes an integral part of the heating assembly rather than a separate component requiring external connection. This consolidation simplifies the overall device structure while preserving the efficient electromagnetic heating capability.
2Use of energy by moving object
If an induction coil connected by wire is used for electromagnetic heating, then heating efficiency is improved, but device size increases
Solution Approach 1:
By removing the connecting wire and external power connection components, the patent reduces the overall device volume. The induction coil is miniaturized and integrated directly into the atomizer, eliminating the space required for wire routing and external connections while maintaining heating efficiency.
Solution Approach 2:
The induction coil is nested within the atomizer structure, with the coil windings arranged in a compact configuration that fits within the existing form factor. This nesting approach allows the electromagnetic heating component to be incorporated without increasing the external dimensions of the device.
3Reliability
If traditional atomizer structure is used, then connection with power supply is established, but structure complexity increases and disposable cartridge replacement becomes difficult
Solution Approach 1:
The patent segments the electronic cigarette into a reusable power supply unit and a disposable atomizer cartridge. The atomizer is designed as a self-contained module with integrated electromagnetic heating, eliminating the need for complex electrical connections between replaceable parts. This segmentation simplifies the atomizer structure and enables easy replacement of disposable cartridges.
Solution Approach 2:
The atomizer is designed as a disposable component that is discarded after use, eliminating the need for complex reusable connections and maintenance. The disposable nature allows for simpler construction without electrical contacts, as each new cartridge provides a fresh, pre-assembled heating assembly.
4Reliability
If traditional atomizer structure is used, then power supply connection is established, but tobacco liquid may flow downward to damage control circuit board
Solution Approach 1:
By segmenting the device into separate disposable atomizer and reusable power supply units, the patent physically isolates the control circuit board from the tobacco liquid reservoir. The atomizer cartridge contains all liquid-handling components, preventing liquid from reaching the electronics in the power supply unit.
Solution Approach 2:
The disposable atomizer cartridge acts as an intermediary barrier between the tobacco liquid and the control circuit board. This intermediate component contains the liquid reservoir and heating elements, preventing direct contact between the liquid and sensitive electronics while still enabling functional connection during operation.
