Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette battery assemblies are prone to unintended battery discharge due to conductive foreign matter entering the housing and contacting the electrodes, posing safety risks when not connected to an atomizer.
Innovation Solution
A battery assembly design featuring a housing with an upper and lower mounting seat, an elastic member, and an electrode contact that is initially separated from the battery electrodes by elastic force, requiring external force to connect, thus isolating the atomizer interface and preventing foreign matter from reaching the electrodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the positive electrode contact is always connected to the positive electrode of the battery and exposed outside the battery assembly, then the connection with the atomizer is simplified, but the risk of battery discharge due to conductive foreign matter entering the housing increases
Solution Approach 1:
The electrode contact is pre-positioned in a separated state by the elastic member before any external force is applied. This preliminary action ensures that the contact is not initially connected to the battery electrode, preventing accidental discharge while maintaining readiness for intentional connection when the atomizer is attached
Solution Approach 2:
The elastic member acts as an intermediary between the electrode contact and the battery electrode. It provides a controlled mechanical connection that can be easily engaged and disengaged, serving as a mediator that allows intentional connection while preventing unintended contact with conductive foreign matter
2Reliability
If the electrode contact is separated from the battery electrode by elastic force, then the safety protection against non-human operation is improved, but the device complexity increases due to additional components
Solution Approach 1:
The elastic member provides self-service by automatically maintaining the electrode contact in a separated position without requiring additional control mechanisms. The elastic force inherently performs the safety function of preventing contact, eliminating the need for complex control systems while maintaining simple operation
Solution Approach 2:
The system transitions from a static connected state to a dynamic state where the electrode contact can move between connected and separated positions. The elastic member enables this dynamic behavior, allowing the contact to be easily engaged when needed while automatically returning to a safe separated position, reducing the need for additional locking or control mechanisms
