Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional low-temperature baked smoking sets with heating elements suffer from insufficient strength, leading to deformation and fracture during insertion and pulling, which affects the atomization effect and heating uniformity of tobaccos.
Innovation Solution
A heating element with a sheet-shaped main substrate and reinforced members extending from its lateral sides, formed by bending and punching a metallic material, enhances strength and prevents bending, while a heating track on the substrate ensures uniform heating and atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a long-strip-shaped flat base material with printed heating track is used, then the device complexity is reduced, but the strength is insufficient causing fracture and deformation during insertion and pulling
Solution Approach 1:
The heating element is divided into a flat base material and separate reinforcing members. The reinforcing members are positioned at specific locations on the flat base material to provide localized strength enhancement without complicating the overall structure. This segmentation allows the heating track printing process to remain simple while adding structural reinforcement where needed.
Solution Approach 2:
The heating element combines the flat base material with reinforcing members to create a composite structure. The reinforcing members are made of the same or similar material as the base material and are integrated through bending or welding processes. This composite approach increases the overall strength and resistance to deformation while maintaining the simplicity of the heating track printing process.
2Strength
If the heating element is made more robust to prevent fracture, then the strength improves, but the ease of manufacture decreases
Solution Approach 1:
The manufacturing process is segmented into distinct steps: first producing the flat base material with heating track, then adding reinforcing members at specific locations. This segmentation allows each component to be manufactured independently using simple processes, and then assembled together, maintaining ease of manufacture while improving strength.
Solution Approach 2:
The reinforcing members are designed with specific geometric parameters (size, shape, position) that can be easily controlled during manufacturing. By optimizing these parameters, the reinforcing members provide maximum strength enhancement with minimal added complexity to the manufacturing process. The reinforcing members can be added through simple bending or welding operations.
3Stability of the object's composition
If reinforcing members are added to prevent bending, then the strength and stability improve, but the device complexity increases
Solution Approach 1:
Reinforcing members are added only at specific locations on the flat base material where strength enhancement is most needed, rather than making the entire structure more complex. This localized approach provides stability where required while keeping the overall device complexity low. The reinforcing members are positioned to address specific deformation issues during insertion and pulling.
Solution Approach 2:
The heating element is segmented into the flat base material and separate reinforcing members. This segmentation allows the reinforcing members to be added as discrete components rather than integrating complexity into the entire structure. The reinforcing members can be independently manufactured and then attached to the flat base material, maintaining overall simplicity.

AI summary
The invention relates to an electronic cigarette, a heating element thereof and a method for manufacturing the heating element. The heating element comprises a sheet-shaped main substrate (11), the main substrate comprises an insertion end (A) and a connection end (B) at two opposite ends, and the insertion end is configured to be inserted into a cigarette. Reinforced members (12) are provided by extending outwardly from two lateral sides between the connection end and the insertion end to improve strength of the main substrate, and prevent the main substrate from bending. The reinforced member is configured to strengthen the main substrate, which effectively reduces virtual connection or floating of the heating track due to deformation or fracture of the heating element during inserting and pulling of tobaccos, and optimizes the atomization effect. Meanwhile, the reinforced member increases a heating area of tobaccos, so as to heat and atomize tobaccos more uniformly, and improve taste of tobaccos.
