Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating devices for tobacco and non-tobacco products are limited to a single type of consumable and lack flexibility in generating aerosols, as they rely on induction coils for heating and do not accommodate different types of aerosol generating products effectively.
Innovation Solution
An aerosol generating device with an induction coil and a power supply that can generate a changing magnetic field for heating aerosol generating products, and a direct current for atomizers, along with a detection system to identify and optimize power output based on the type of consumer product, allowing compatibility with both aerosol generating products and atomizers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses only an induction coil for heating, then the structure is simple, but the device can only accommodate a particular type of consumable and lacks versatility
Solution Approach 1:
The heating system is designed to support multiple types of consumables (aerosol generating products with induction heating elements and atomizers with electrical contacts) through a single device. The induction coil can heat aerosol generating products, while the electrical contact system can power atomizers, enabling one device to serve multiple functions and accommodate different consumable types.
Solution Approach 2:
The heating system is segmented into two independent subsystems: an induction heating subsystem (induction coil) for aerosol generating products and an electrical heating subsystem (electrical contact + power supply) for atomizers. This segmentation allows each subsystem to be optimized for its specific consumable type while both coexist in the same device.
2Adaptability or versatility
If the device includes both induction coil and direct current output system, then the device can heat both solid and liquid-based consumables, but the device complexity increases
Solution Approach 1:
The control system dynamically switches between different heating modes (induction mode and electrical mode) based on the type of consumable detected. The circuit board can selectively activate the induction coil or the electrical contact system, allowing the device to adapt its heating mechanism according to the inserted consumable type, thereby managing complexity through intelligent control rather than physical complexity.
Solution Approach 2:
The device incorporates a detection mechanism (such as detecting electrical characteristics or physical presence) to identify the type of consumable inserted into the receiving cavity. Based on this feedback, the control circuit automatically selects the appropriate heating system, enabling automatic adaptation without requiring manual intervention and simplifying the user experience despite the dual-system complexity.
3Power
If the first electrical contact is located inside the receiving cavity, then the electrical connection is direct, but the induction coil cannot effectively generate magnetic field for aerosol generating products
Solution Approach 1:
The receiving cavity is functionally segmented into two zones: an induction heating zone (where the induction coil operates without obstruction) and an electrical contact zone (where the electrical contact establishes connection). The first electrical contact is positioned to avoid interfering with the induction coil's magnetic field generation, allowing both heating methods to operate effectively in their respective zones.
Solution Approach 2:
The first electrical contact serves as an intermediary element that can be selectively engaged or disengaged based on the consumable type. When an atomizer is inserted, the electrical contact provides a direct power path. When an aerosol generating product is inserted, the electrical contact remains disengaged or inactive, allowing the induction coil to operate unimpeded. This intermediary approach allows the system to switch between power delivery methods without permanent interference.

AI summary
Provided in the present application are an aerosol generation device and an aerosol generation system. The aerosol generation device comprises: a power source; a receiving cavity, which is used for receiving an aerosol generation product comprising a first heating element; an induction coil, which is connected to the power source and is arranged at least partially around the receiving cavity, wherein the induction coil generates a changing magnetic field when powered on, so as to induce the first heating element to heat the aerosol generation product; and a first electrical contact, which is connected to the power source and is located outside the receiving cavity or avoids the receiving cavity, wherein when an atomizer comprising a second heating element and a liquid matrix is combined with the aerosol generation device, the first electrical contact is configured to output a direct current to the second heating element, and thus the second heating element heats the liquid matrix to generate aerosol. The aerosol generation device can generate a magnetic field by means of an induction coil, so as to induce the heating of an aerosol generation product, and can output a direct current by means of a first electrical contact, so as to supply power to an atomizer to heat and atomize a liquid matrix.
