Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a heating wire is directly immersed into the tobacco material, then heating efficiency is improved, but the quality of the tobacco material degrades
Solution Approach 1:
The patent introduces an intermediary substance (liquid-guiding material or ceramic cup with liquid) between the heating source and tobacco material. This intermediary absorbs microwave energy and transfers heat to the tobacco material indirectly, preventing direct contact with the heating wire while maintaining efficient heating through thermal conduction from the heated liquid medium.
Solution Approach 2:
The patent replaces the conventional direct-contact mechanical heating system with a microwave-based heating system. The microwave generator produces electromagnetic waves that heat the intermediary substance, which then transfers heat to the tobacco material, eliminating the need for direct mechanical contact between the heating wire and tobacco.
2Productivity
If microwave energy is released into the cylindrical shielding net, then heating efficiency is improved, but microwave energy may be lost without proper containment
Solution Approach 1:
The patent converts the potentially harmful microwave energy leakage into a beneficial containment system. The cylindrical shielding net with its specific mesh structure and the cover work together to reflect and concentrate microwave energy back onto the tobacco material, turning what could be energy loss into enhanced heating efficiency.
Solution Approach 2:
The cylindrical shielding net serves multiple functions: it contains and directs microwave energy, supports the cup structure, and works with the cover to create a closed heating chamber. This multi-functional design improves overall system efficiency while preventing energy loss.
3Productivity
If a cover is added to hold microwave energy in the cylindrical shielding net, then heating efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs a cover that forms a flexible or semi-rigid closure for the cylindrical shielding net. This thin-film or shell structure effectively contains microwave energy while adding minimal structural complexity, maintaining simplicity in the overall device design.
4Object-affected harmful factors
If a non-metallic cup is used to accommodate tobacco material, then material degradation is prevented, but microwave penetration may be affected
Solution Approach 1:
The patent specifies that the non-metallic cup should have porous characteristics, allowing microwave energy to penetrate through the cup walls and reach the tobacco material. The porous structure enables sufficient microwave transmission while maintaining the benefit of non-metallic contact that prevents material degradation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The microwave heating module efficiently heats and atomizes tobacco material without degrading it, providing a more environmentally friendly and efficient alternative to conventional heating wires.
Implementation Method 1
the magnetron emits microwave; the microwave is released via the microwave source into the cylindrical shielding net to heat and atomize the tobacco material in the cup
Implementation Method 2
the microwave is released via the microwave source into the cylindrical shielding net to heat and atomize the tobacco material in the cup
Implementation Method 3
the cover is disposed on the cylindrical shielding net so as to hold the microwave emitted by the microwave source in the cylindrical shielding net, thereby concentrating the microwave energy on the tobacco material
Implementation Method 4
a microwave heating module and an aerosol generator; the microwave heating module comprises a cup, a cylindrical shielding net, a magnetron, and a microwave source

AI summary
An electronic cigarette includes a microwave heating module and an aerosol generator. The microwave heating module includes a cup (4), a cylindrical shielding net (5), a magnetron (7), and a microwave source (8). The cup is fixed in the cylindrical shielding net for accommodating a tobacco material. The cylindrical shielding net is disposed above the microwave source. The magnetron is disposed on the microwave source. In a power-on state, the magnetron emits microwave. The microwave is released via the microwave source into the cylindrical shielding net to heat and atomize the tobacco material in the cup. The microwave heating module is disposed in the aerosol generator.
