Magnetic Flavor Inhaler Heating for Secure Hold and Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-combustion-heating-type flavor inhalers face challenges in securely fixing and easily removing a flavor molded body during and after use, as existing solutions do not effectively manage the magnetic adhesion forces at varying temperatures.
Innovation Solution
Incorporating a magnet or magnetically attracting material within the flavor molded body and a heat-transmitting member with a magnetically attracting material, where the magnetic attraction force decreases with temperature, allowing secure fixation and easy detachment, utilizing a magnetic force measurement method to ensure the magnetic adhesion strength is reduced after heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnet is used to fix the flavor molded body in the flavor molded body accommodation part, then the flavor molded body can be securely fixed during use, but the flavor molded body cannot be easily removed after use due to strong magnetic adhesion
Solution Approach 1:
The patent applies parameter changes by utilizing temperature-dependent magnetic properties. The magnetic body's adhesion force changes based on temperature: at room temperature it provides strong fixation, but when heated to a specific temperature range (150-250°C), the magnetic adhesion force decreases, enabling easy removal. This resolves the contradiction between secure fixation and easy removal by changing the temperature parameter.
2Reliability
If the magnetic adhesion force is strong to ensure secure fixation, then the flavor molded body remains stable during heating, but the magnetic body may overheat or cause safety issues
Solution Approach 1:
The patent utilizes the temperature-dependent magnetic properties of the magnetic body to create a safety mechanism. As the temperature increases during heating, the magnetic adhesion force naturally decreases, providing a passive safety feature that prevents overheating and potential safety issues while maintaining stable fixation at operating temperatures.

AI summary
A non-combustion-heating-type flavor inhaler, in which a flavor molded body can be fixed in position during use and from which the flavor molded body can be easily removed after use, includes a flavor molded body including a tobacco powder raw material, an aerosol source, and a magnet or a magnet adsorption material that adsorbs the magnet using magnetic force; a flavor molded body accommodation part for accommodating the flavor molded body; a power supply unit provided with a power supply part; a first heating unit for receiving a supply of electric power from the power supply part and generating heat; and a heat-transmitting member provided on the inner wall of the flavor molded body accommodation part. The heat-transmitting member transmits heat from the first heating part to the flavor molded body. The heat-transmitting member includes the magnet adsorption material if the flavor molded body includes the magnet, and includes the magnet if the flavor molded body includes the magnet adsorption material. The tensile force measured in the magnet when the magnet is heated to 140° C. is 95% or less of the tensile force measured in the magnet at 20° C.
