Solution Overview
Problem
Ultrasonic atomizing sheets in electronic cigarette atomizers face efficiency issues due to vibration absorption by elastic insulating gaskets and poor electrical connections, leading to incomplete e-liquid atomization and complex, costly assembly processes.
Innovation Solution
The electronic cigarette atomizing core features an ultrasonic atomizing sheet stacked with an elastic insulating gasket and an electrode assembly, where bosses on the gasket provide point-to-point contact to reduce vibration absorption and an adjustable propping post ensures stable electrical connection, improving atomization efficiency and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the insulating gasket is made of silicone with elasticity and softness to stably cover the ultrasonic atomizing sheet, then the coverage stability is improved, but the gasket absorbs the amplitude and frequency of the ultrasonic atomizing sheet, reducing working efficiency
Solution Approach 1:
The insulating gasket is segmented into multiple protrusions that contact the ultrasonic atomizing sheet at discrete points rather than a continuous surface. This segmentation reduces the contact area, minimizing vibration absorption while maintaining stable coverage through the distributed protrusion structure
Solution Approach 2:
The insulating gasket transitions from uniform material properties to having localized protrusions with specific geometric characteristics. The protrusions provide localized contact points that maintain electrical insulation and mechanical stability while minimizing the overall contact area to reduce vibration damping effects
2Reliability
If the ultrasonic atomizing sheet is electrically connected by welded electronic lines or direct abutting using a spring, then electrical connection is achieved, but the connection is prone to poor electrical contact and the assembly is complicated, increasing costs
Solution Approach 1:
The electrical connection function is merged with the insulating gasket structure itself. The gasket incorporates conductive elements or contact structures that provide both electrical connection and insulation functions, eliminating the need for separate spring abutting mechanisms or welded electronic lines
Solution Approach 2:
The insulating gasket is designed to perform multiple functions simultaneously: electrical insulation, mechanical support, vibration isolation, and electrical connection. This multi-functionality simplifies the overall assembly by eliminating separate components for each function
3Reliability
If a spring is used for abutting of the ultrasonic atomizing sheet, then electrical connection is maintained, but the elastic force is not easy to control, affecting atomizing efficiency and service life
Solution Approach 1:
The design transitions from using spring elastic force to using the geometric parameters of the protrusions (height, diameter, spacing) to control the contact pressure. This allows precise control of the elastic force through manufacturing parameters rather than relying on spring material properties and dimensions
