Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single heating mode is used, then the device structure is simple, but it cannot meet various user requirements for vapor amount and has low heating efficiency in cold environments
Solution Approach 1:
The heating system is divided into two independent heating assemblies: a first heating assembly for direct conduction heating of the substance, and a second heating assembly for heating air that then flows into the receiving chamber. Each assembly can operate independently or simultaneously, providing multiple heating modes (conduction mode, airflow mode, and hybrid mode) to meet different user requirements and environmental conditions.
2Productivity
If the first heating assembly operates alone, then the heating mode is simple, but the heating efficiency is insufficient in low-temperature environments
Solution Approach 1:
The patent combines two different heating mechanisms (conduction heating and airflow heating) into a single system. The first heating assembly provides direct conduction heating, while the second heating assembly heats air that flows into the receiving chamber to indirectly heat the substance. Both assemblies can operate simultaneously to provide enhanced heating efficiency in cold environments, or independently when only one mode is needed.
3Reliability
If dual heating assemblies operate simultaneously, then the heat supply is sufficient in cold environments, but the device complexity increases
Solution Approach 1:
The system incorporates an electric control assembly that dynamically controls the operation of the two heating assemblies based on different working conditions. The control assembly can switch between different heating modes (conduction mode, airflow mode, hybrid mode) and adjust the power output of each heating assembly, allowing the system to adapt to varying temperature conditions and user requirements while maintaining reliable heat supply.

AI summary
A smoking device includes a first heating assembly, a second heating assembly, and an electric control assembly. The first heating assembly has a receiving chamber used to receive a substance to be heated, and the first heating assembly is used to heat the substance to be heated. The second heating assembly has an airflow passage being in communication with the outside, the airflow passage is in communication with the receiving chamber so as to allow outside air to enter the receiving chamber through the airflow passage, and the second heating assembly is configured to heat the air entering the airflow passage. The electric control assembly is electrically connected to both heating assemblies to control heating operations of the heating assemblies, such that when the smoking device is working, at least one of the first heating assembly and the second heating assembly performs the heating operations.
