Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic vaporization devices face issues where the to-be-vaporized liquid can leak into the microphone and control panel through the airway, causing damage.

Innovation Solution

A power supply component design featuring a housing with an accommodating portion, a holder, and a vent channel that allows outside air to enter, preventing liquid from reaching the microphone and control panel by using a blocking portion and air inlet holes to direct airflow and prevent direct exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the microphone airway is directly connected to the vaporization component, then the microphone can detect suction air flow changes, but liquid can enter the microphone and control panel causing damage

Engineering Contradiction:

Improvemicrophone detection functionVSAvoidliquid damage to microphone and control panel

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A blocking portion is introduced as an intermediary element between the vaporization component and the microphone airway. This blocking portion prevents liquid from directly reaching the microphone and control panel while still allowing air flow to pass through for detection purposes

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The airway is segmented into different sections: a first airway section that can be exposed to liquid from the vaporization component, and a second airway section that remains protected. The blocking portion creates this segmentation, allowing the microphone to detect air flow in the protected section while preventing liquid contamination

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If the start airway is blocked to prevent liquid entry, then liquid damage is avoided, but outside air cannot enter the start airway for proper device operation

Engineering Contradiction:

Improveliquid damage preventionVSAvoidairflow for device operation

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Different sections of the airway system are given different properties: the first airway section has opening(s) to allow outside air entry, while the second airway section is blocked to prevent liquid entry. This local differentiation allows both functions to coexist - air can enter through the first section while liquid is blocked from reaching the microphone in the second section

AI summary

A power supply component includes: a housing having an accommodating portion; and a holder arranged on the accommodating portion, a start airway being arranged on the holder, a vent channel being defined between an end of the holder connectable to a vaporization component and the housing, the vent channel being in communication with the start airway and outside air such that the outside air enters the start airway through the vent channel.
