Solution Overview

Problem

Existing electrically heated aerosol generating systems, such as smoking utensils, are difficult to manufacture due to complex heater structures.

Innovation Solution

The system incorporates a heating element with a first cross section connected to support elements, where the support elements have a greater cross section than the heating element, allowing for easier assembly and manufacturing, and are integrally formed with the heating element to provide structural support and reduce energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex heater structure is used, then heating performance is improved, but manufacturing difficulty increases

Engineering Contradiction:

Improveheating performanceVSAvoidmanufacturing difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The heater is divided into distinct functional components: a heating element with first cross-section for heat generation, and support elements with greater cross-section for structural function. This segmentation allows each component to be optimized independently - the heating element for thermal performance and the support elements for mechanical strength and ease of manufacturing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support elements are integrally formed with the heating element, combining structural support and electrical heating functions into a single unified component. This integration eliminates the need for separate assembly steps while maintaining the distinct functional zones of different cross-sections.

Inventive Principle:

Principle #5Merging (Combining)

2Strength

If support elements with greater cross section are used, then structural support is improved, but material consumption increases

Engineering Contradiction:

Improvestructural supportVSAvoidmaterial consumption

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The heater structure employs varying cross-sections at different locations: the support elements have greater cross-section where structural strength is needed, while the heating element portions have smaller cross-section where heat generation is the primary function. This local differentiation of properties optimizes both structural support and material efficiency.

Inventive Principle:

Principle #3Local quality
