Solution Overview

Problem

Existing electronic cigarettes face issues with poor electrical contact between the first electrode of the atomization assembly and the second electrode of the battery assembly due to machining or assembling errors, leading to clearance and poor contact.

Innovation Solution

The design of the first electrode includes a base portion and a connecting portion extending in different directions, with the second electrode arranged to deviate from the connecting portion, ensuring a larger contact area and stable connection, enhanced by magnetic elements and elastic components for secure electrical contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the first electrode and second electrode are aligned for direct contact, then electrical connection is achieved, but machining and assembling errors cause clearance and poor contact

Engineering Contradiction:
Improveelectrical contact reliabilityVSAvoidelectrode alignment precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The first electrode is designed with a flexible connecting portion that can dynamically adjust its position and angle. This flexible section allows the electrode to bend and adapt to clearance issues caused by machining or assembling errors, maintaining reliable electrical contact without requiring high precision manufacturing

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The electrode structure changes its physical parameters (bending angle, contact position) through the flexible connecting portion. This parameter adjustment allows the electrode to compensate for alignment errors and maintain optimal contact with the second electrode despite manufacturing variations

Inventive Principle:
Principle #35Parameter changes

2Area of stationary object

If the first electrode uses a simple linear structure, then manufacturing is easy, but contact area with the second electrode is limited

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The first electrode is segmented into distinct functional portions: a base portion for structural support and electrical connection, and a connecting portion with flexible characteristics. This segmentation allows each part to be optimized independently - the base portion maintains simplicity for easy manufacturing while the connecting portion provides enhanced contact area through its ability to conform to the second electrode surface

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the electrode structure is made rigid for stability, then structural strength is improved, but adaptability to different battery assembly specifications is reduced

Engineering Contradiction:

Solution Approach 1:

The flexible connecting portion introduces dynamic adaptability to the electrode structure. It can bend and adjust its configuration to match different battery assembly specifications and electrode positions, while the base portion and overall structure maintain sufficient rigidity and strength for structural stability and mechanical support

Inventive Principle:
Principle #15Dynamics
