Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomization devices have poor assembly efficiency and maintainability due to the use of welding to fix the incentive assembly and built-in circuit board, which complicates the assembly process and hinders maintenance.
Innovation Solution
The atomization device features a housing assembly with an extending protrusion and conductive pieces fixed on it, along with a docking boss that allows for contact with conductive terminals without welding, and a detachable battery assembly with elastic arms for secure connection, enhancing assembly efficiency and maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to fix the incentive assembly and built-in circuit board, then connection strength is improved, but assembly efficiency deteriorates and maintainability worsens
Solution Approach 1:
The device is divided into separable modules: the incentive assembly with conductive pieces can be detached from the handle assembly with conductive terminals. This segmentation allows each module to be manufactured, tested, and replaced independently, eliminating the need for welding while improving assembly efficiency and maintainability.
Solution Approach 2:
Conductive pieces and conductive terminals serve as intermediary components that enable electrical connection between the incentive assembly and battery assembly without direct welding. These intermediaries provide both electrical conductivity and mechanical connection through snap-fit or plug-and-play interfaces.
2Reliability
If welding is used to fix the incentive assembly and built-in circuit board, then connection reliability is improved, but ease of repair deteriorates
Solution Approach 1:
The incentive assembly is designed as a separate, detachable module from the handle assembly. This segmentation enables the incentive assembly to be quickly removed and replaced without complex repair procedures, significantly improving ease of repair while maintaining connection reliability through dedicated conductive connection interfaces.
Solution Approach 2:
The design allows the incentive assembly to be easily discarded (removed) and replaced (recovered) when needed. The conductive pieces and terminals are designed to maintain reliable electrical connection during normal use but allow simple detachment for replacement, embodying the discarding and recovering principle.
3Productivity
If conductive pieces are fixed on the extending protrusion without welding, then assembly efficiency is improved, but connection stability may deteriorate
Solution Approach 1:
The connection interface between conductive pieces and terminals is designed to be dynamically secure during assembly and use, allowing for easy insertion and removal while maintaining stable electrical connection during operation. The elastic arms and receiving groove structure provide automatic engagement and retention forces.
Solution Approach 2:
The welding process (thermal-mechanical system) is replaced with a purely mechanical snap-fit connection system using conductive pieces, terminals, elastic arms, and receiving grooves. This substitution achieves both assembly efficiency and connection stability through precision-machined mechanical interfaces.
