Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a metallic heating wire is used in the atomizer, then heating efficiency is improved, but dry-burning occurs due to improper assembly and contact between the heating wire and base seat
Solution Approach 1:
The patent introduces a ceramic base seat as an intermediary material between the heating wire and the metal components. The ceramic material provides thermal insulation and electrical isolation, preventing direct contact between the heating wire and metal base seat that causes short circuits and dry-burning. This mediator resolves the contradiction by maintaining heating efficiency while improving assembly reliability through proper electrical and thermal management.
Solution Approach 2:
The patent uses a composite structure combining ceramic and metal materials in the base seat assembly. The ceramic portion provides insulation and structural support, while metal components provide mechanical strength and electrical connection points. This composite approach allows the heating wire to be properly positioned and secured without direct metal-to-metal contact, resolving the assembly reliability issue while maintaining effective heating performance.
2Adaptability or versatility
If the atomizer is not used for a time period and then reactivated, then portability is improved, but condensed e-liquid splashes easily affecting user experience
Solution Approach 1:
The patent incorporates a liquid guiding member with grooves that pre-direct the flow path of e-liquid before it reaches the heating wire. This preliminary action ensures that condensed e-liquid is channeled along a controlled path during reactivation, preventing random splashing. The liquid guiding structure is prepared in advance to handle the sudden heating and e-liquid vaporization that occurs when the atomizer is reactivated after storage.
Solution Approach 2:
The liquid guiding member features a porous or grooved structure that allows controlled absorption and distribution of e-liquid. This structure manages the condensed e-liquid by providing capillary channels that guide the liquid away from the heating wire area, preventing splashing while maintaining proper e-liquid supply to the heating element for consistent atomization during portability use.
3Stability of the object's composition
If a ceramic base seat is used, then temperature consistency is improved and dry-burning is prevented, but manufacturing complexity increases
Solution Approach 1:
The patent divides the base seat into separate ceramic and metal components rather than creating a fully integrated complex ceramic structure. The ceramic portion is manufactured as a separate insulating component with standardized shapes, and the metal components are fabricated separately and assembled together. This segmentation simplifies the manufacturing of each individual part while achieving the overall temperature consistency and electrical isolation benefits of a ceramic base seat.
Solution Approach 2:
The ceramic base seat component is designed to perform multiple functions simultaneously: providing thermal insulation, electrical isolation, mechanical support, and structural integration. By making this single component multi-functional, the patent reduces the need for additional separate parts, thereby simplifying the overall assembly process and manufacturing complexity while maintaining temperature consistency and preventing dry-burning.
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 ceramic base seat maintains consistent atomizing temperature, prevents dry-burning, and absorbs condensed e-liquid, ensuring a consistent user experience and reducing splashing, thereby improving taste and operational reliability.
Implementation Method 1
The liquid guiding member is configured for absorbing and/or storing e-liquid for the heating member to perform an atomizing action
Implementation Method 2
The electronic cigarette provides power for the heating member of the atomizer by a battery, causing the heating member to be driven by electricity and heat the e-liquid to generate smoke
Implementation Method 3
the base seat made of ceramic material can retain the atomizing temperature well, causing the taste during the next inhaling to be nearly the same as the previous inhaling
Implementation Method 4
the base seat made of ceramic material can absorb a part or all of the e-liquid condensed in the atomizing chamber, when the atomizer is used again, the splashing oil can be avoided

AI summary
A heating device, an atomizer and an electronic cigarette. The heating device comprises a heating member (530), a liquid guide member, and a base (532). The heating member (530) is provided therein with an airflow passage (5301) through which the airflow passes. The liquid guide member is used for absorbing and/or storing e-liquid to be atomized by the heating member (530). Both the heating member (53) and the liquid guide member are mounted in the base (532). The base (532) is made of a ceramic material and can retain a certain atomization temperature so that the smoking mouth feel each time has little difference, and moreover, dry burning caused by improper assembly is avoided from affecting the smoking mouth feel.
