Solution Overview

Problem

Existing inhaler devices struggle to maintain the source material within a precise temperature range around the vaporization temperature of the substance, leading to inefficient delivery and potential overheating or underheating.

Innovation Solution

A method and device for controlling the temperature of the source material in an inhaler, involving heating the source material to a first temperature and then gradually reducing the heating to a second temperature, maintaining the source material within 50°C of the vaporization temperature range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the source material is heated to a high temperature to ensure vaporization, then the delivery efficiency is improved, but the source material may overheat and degrade

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic temperature control by transitioning from static heating to a two-stage heating process. The system dynamically adjusts heating intensity: first heating to a first temperature (below vaporization point) to stabilize airflow, then increasing to a second temperature (at or above vaporization point) for efficient vaporization. This dynamic adjustment prevents overheating while maintaining delivery efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies preliminary action by first heating the source material to a first temperature below the vaporization point before reaching the target vaporization temperature. This preliminary heating stage stabilizes the airflow through the source material, ensuring proper airflow conditions are established before the main vaporization phase begins, thus preventing overheating and degradation.
