Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If charcoal burning mode is adopted as heating mode, then heating function is provided, but temperature control is slow and tobacco may be scorching
Solution Approach 1:
The patent replaces the mechanical charcoal burning system with an electronic heating system consisting of a heating element, temperature sensing device, and control circuit. This substitution enables precise electronic control of heating power, allowing rapid temperature adjustment without the inherent delays of charcoal combustion control.
Solution Approach 2:
The patent implements a feedback control mechanism where a temperature sensing device continuously monitors the heating area temperature and feeds this information to the control circuit. The control circuit adjusts heating element power output based on this feedback, maintaining precise temperature control and preventing tobacco scorching through real-time temperature regulation.
2Power
If charcoal burning temperature is raised high, then heating capability is improved, but tobacco will be scorching
Solution Approach 1:
The patent employs dynamic temperature control where the heating element power output is continuously adjusted based on real-time temperature feedback. This dynamic adjustment allows the system to maintain optimal heating capability while preventing temperature excursions that would cause tobacco scorching, adapting power output to actual heating needs.
Solution Approach 2:
The temperature sensing device provides continuous feedback on heating area temperature to the control circuit, which modulates heating element power accordingly. This closed-loop feedback ensures that heating capability is maintained at sufficient levels for effective tobacco heating while automatically reducing power to prevent scorching, eliminating the harmful effect of excessive temperature.
3Object-affected harmful factors
If charcoal burning temperature is lowered, then tobacco scorching is prevented, but smoke volume becomes insufficient
Solution Approach 1:
The dynamic heating control system continuously adjusts heating element power output based on real-time temperature feedback and smoke generation needs. This enables the system to maintain temperatures sufficient for generating adequate smoke volume while preventing scorching through real-time modulation, adapting power to achieve optimal smoke production without harmful temperature excursions.
Solution Approach 2:
The temperature feedback mechanism allows the control circuit to precisely regulate heating power to maintain optimal temperature ranges for smoke generation. By continuously monitoring temperature and adjusting power output accordingly, the system ensures sufficient smoke volume is generated while preventing tobacco scorching through precise temperature management.
4Temperature
If charcoal burning is used, then heating function is achieved, but heating time is prolonged
Solution Approach 1:
The patent replaces the slow-heating charcoal burning mechanism with an electric heating element that can rapidly reach operating temperatures. This substitution eliminates the prolonged heating time characteristic of charcoal combustion while maintaining effective heating function for tobacco material processing.
Solution Approach 2:
The heating element operates with controlled periodic heating cycles, rapidly heating the tobacco material and then allowing thermal conduction to distribute heat throughout the chamber. This periodic action pattern enables quick initial heating while maintaining effective temperature distribution, significantly reducing overall heating time compared to continuous charcoal burning.

AI summary
Disclosed is an electronic hookah with a sheet-like heating device, which is used for heating a tobacco material, and includes a main unit. The main unit is provided with a sheet-like heating element, and a protective cover arranged on one side of the sheet-like heating element facing the tobacco material. During heating, the sheet-like heating element uniformly conducts heat to the tobacco material through the protective cover and heats the tobacco material and surrounding air. With the sheet-like heating element and the protective cover, convenient temperature control is achieved, and the tobacco material can be uniformly heated, thereby avoiding the problems that the tobacco is scorched due to excessively high charcoal burning temperature and insufficient smoke volume due to excessively low charcoal temperature. Moreover, the electronic hookah can be quickly heated, to generate a sufficient smoke volume, and both temperature and smoke quality can be controlled.
