Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating elements for electronic cigarettes are costly due to the need for a support and guide tube to fix the heating wire, and they lack efficient vapor guidance and bubble removal during e-liquid loading.
Innovation Solution
A heating element with a cylindrical body featuring a central through hole and a flat, coiled heating wire, soldered pins, and grooves for bubble removal, allowing direct vapor guidance through the through hole without additional support or guide tube, enhancing vapor production and e-liquid loading efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support and guide tube are added to fix the heating wire, then the heating wire can be securely positioned, but the device complexity and cost increase
Solution Approach 1:
The patent removes the support and guide tube components from the conventional heating element structure. The heating wire is directly positioned and fixed within the cylindrical body without requiring additional support structures, thereby reducing device complexity while maintaining functional reliability
Solution Approach 2:
The heating wire positioning function is merged into the cylindrical body structure itself. The body's geometry and internal configuration directly provide the positioning function that was previously separated into distinct support and guide tube components, reducing the total component count
2Reliability
If a support and guide tube are added to fix the heating wire, then the heating wire can be securely positioned, but the manufacturing cost increases
Solution Approach 1:
The patent eliminates the support and guide tube components that increase manufacturing cost. By directly positioning the heating wire within the cylindrical body without additional support structures, the manufacturing process is simplified and cost is reduced while maintaining positioning stability
Solution Approach 2:
The patent uses a simpler, more cost-effective structure where the heating wire is directly fixed in the body without expensive additional components. This approach prioritizes cost reduction while maintaining adequate functionality for the heating wire positioning
3Productivity
If grooves are added to the upper surface for bubble removal, then air bubbles can be effectively removed during e-liquid loading, but the device complexity increases
Solution Approach 1:
The upper surface of the cylindrical body is segmented into multiple grooves that divide and channel air bubbles during e-liquid loading. This segmentation allows bubbles to be effectively removed through the grooves while maintaining a relatively simple overall structure that integrates smoothly into the cylindrical body
4Productivity
If the heating wire is made as a flat coiled structure, then the heating area is increased and vapor production is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The heating wire is configured as a flat coiled structure lying in one plane rather than a vertical three-dimensional coil. This dimensional change increases the heating area and improves vapor production efficiency, while the planar configuration can be more easily manufactured with standard precision techniques
