Solution Overview

Problem

The electrode connecting element is difficult to assemble and the heating element is prone to scratching during assembly in aerosol generation apparatuses.

Innovation Solution

A heating assembly with sheet-shaped electrode connecting elements that are fixed using a fixing base, comprising a base and an upper cover, which are sleeved on the heating element, allowing for attachment rather than sleeving, thereby avoiding friction and scratching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an electrode connecting element is used to achieve electric connection of the electrode, then electric connection is established, but the electrode connecting element is difficult to assemble and may scratch the heating film on the heating element

Engineering Contradiction:
Improveelectric connectionVSAvoidassembly difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The electrode connecting element is divided into a sheet-shaped body and a separate fixing base (comprising base and upper cover). The sheet-shaped body is easily attached to the electrode, while the fixing base provides secure fixation without complex assembly steps, resolving the contradiction between reliable connection and ease of assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing base acts as an intermediary component between the sheet-shaped electrode connecting element and the heating element. It provides a dedicated fixing structure that secures the connecting element without requiring direct manipulation of the heating film, thus preventing scratching while maintaining assembly simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If an electrode connecting element is used to achieve electric connection of the electrode, then electric connection is established, but the heating element is prone to scratching during assembly

Engineering Contradiction:
Improveelectric connectionVSAvoidscratching damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By separating the electrode connecting function (sheet-shaped body) from the fixation function (fixing base), the design eliminates the need for the connecting element to directly interact with and potentially scratch the heating film during assembly, while maintaining reliable electrical connection

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing base serves as a protective intermediary that handles the fixation task, preventing the electrode connecting element from directly contacting and scratching the heating film during the assembly process, thus eliminating the harmful scratching effect

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A heating assembly (10) and an aerosol generation apparatus. The heating assembly (10) comprises a heating body (11), an electrode (12) and an electrode connecting member (13). The heating body (11) is used for accommodating and heating an aerosol generation substrate when powered on; the electrode (12) is arranged on the heating body (11) and is electrically connected to the heating body (11); and the electrode connecting member (13) is electrically connected to the electrode (12), wherein the electrode connecting member (13) is flake-like and has a first end and a second end, which are arranged spaced apart from each other in a bending direction. The heating assembly (10) and the aerosol generation apparatus can prevent friction between the electrode connecting member (13) and the heating body (11) during assembly, thereby preventing the electrode connecting member (13) from scratching a heating film (114) or a heating coating layer on the surface of the heating body (11).
