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

VSEngineering 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

Engineering Contradiction:
Improveheating element structureVSAvoidheating element strength
Core Design Contradiction:
Device complexityVSStrength

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #40Composite materials

2Strength

If the heating element is made more robust to prevent fracture, then the strength improves, but the ease of manufacture decreases

Engineering Contradiction:
Improveheating element strengthVSAvoidheating element manufacturing
Core Design Contradiction:
StrengthVSEase of manufacture

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improveheating element stabilityVSAvoidheating element structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #1Segmentation

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.
