Solution Overview

Problem

The existing battery compartments of electronic cigarettes tend to wobble and cause chipping of the lacquer on the cover when opened, due to an undesirable angle of rotation.

Innovation Solution

A battery compartment design featuring a frame, a main body, a cover with a blocking groove, and an elastic pushing rod that extends into the groove to provide elastic support and resistance, preventing wobbling and chipping during rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cover is made rotatable to enable opening and closing, then the ease of operation is improved, but the cover will wobble and impact the main body causing lacquer chipping

Engineering Contradiction:
Improveease of opening and closingVSAvoidstability of cover during rotation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The elastic pushing rod is pre-loaded to provide continuous elastic force on the cover before rotation occurs. This preliminary elastic support prevents the cover from wobbling and impacting the main body during the opening and closing rotation, thereby resolving the contradiction between ease of operation and reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The elastic pushing rod acts as a cushioning element that absorbs and mitigates the impact forces between the cover and main body during rotation. By providing elastic support in advance, it prevents lacquer chipping while maintaining the rotatable opening function

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
