Solution Overview
Problem
The connection reliability between the battery and the built-in circuit board in existing atomization devices is inadequate, leading to potential electrical instability and performance issues.
Innovation Solution
The atomization device incorporates a handle assembly with a battery assembly that includes a mounting seat, a built-in circuit board, and connection terminals (first and second connection terminals) to ensure reliable electrical connections between the battery's positive and negative poles and the circuit board, utilizing metal sheets, bridging portions, and springs for secure contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simple connection structure is used between battery and circuit board, then device complexity is reduced, but connection reliability deteriorates
Solution Approach 1:
The connection structure is divided into separate functional components: connection terminals with metal sheets for electrical contact, springs for mechanical pressure, and mounting portions for circuit board attachment. This segmentation allows each component to be optimized independently while improving overall connection reliability without excessive complexity.
Solution Approach 2:
Metal sheets serve as intermediary elements between the battery poles and the circuit board, providing reliable electrical connection. The springs act as intermediaries to maintain continuous contact pressure. These intermediary components ensure stable electrical connection while distributing the connection function across multiple elements rather than relying on a single complex structure.
2Reliability
If connection terminals with multiple components are used, then connection reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The connection terminal integrates multiple functions into a single component structure: the metal sheet provides electrical conduction, the mounting portion provides mechanical attachment to the circuit board, and the spring provides contact pressure. This merging of functions into integrated components simplifies assembly while maintaining high connection reliability.
Solution Approach 2:
The connection terminal structure serves multiple purposes simultaneously: electrical connection, mechanical fixation, and contact pressure maintenance. This multi-functionality reduces the need for separate components, thereby simplifying manufacturing and assembly processes while ensuring reliable electrical connection between the battery and circuit board.
