Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-burning type flavor inhalers face challenges in maintaining consistent aerosol inhalation efficiency due to variations in puff duration, leading to inadequate aerosol intake for shorter puffs and reduced taste experience for longer puffs.
Innovation Solution
A non-burning type flavor inhaler with a control unit that adjusts power supply to the atomizer based on standard and reduced modes, optimizing power delivery during different puff intervals to enhance aerosol generation and user satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant power is supplied to the atomizer, then the atomizer operates stably, but users with shorter puff durations receive insufficient aerosol
Solution Approach 1:
The patent applies dynamics by transitioning from constant power supply to variable power supply based on puff duration. The control unit dynamically adjusts the power amount to the atomizer during the puff action, switching between standard mode and reduced mode according to the detected puff duration, thereby optimizing aerosol generation for different user inhalation patterns.
Solution Approach 2:
The patent implements parameter changes by modifying the power supply parameter to the atomizer based on puff duration. When puff duration is shorter than the standard duration, the control unit changes the power parameter from the standard power amount to a reduced power amount, ensuring adequate aerosol intake regardless of puff duration variations.
2Quantity of substance
If high power is supplied continuously, then aerosol generation is maximized, but decomposed substances are generated and taste degrades
Solution Approach 1:
The patent applies periodic action by dividing the power supply into distinct phases during puff duration. The control unit provides standard power amount only during the initial standard duration period, then reduces power for the remaining puff duration. This periodic power adjustment ensures sufficient aerosol generation initially while preventing decomposed substance formation in later stages.
Solution Approach 2:
The patent implements partial action by providing high power (standard power amount) only for the necessary initial duration to generate sufficient aerosol, rather than maintaining high power throughout the entire puff action. This prevents excessive heating that would lead to decomposed substance generation while still achieving adequate aerosol intake.
3Quantity of substance
If power supply is adjusted for short puffs, then aerosol intake is improved, but longer puffs may receive excessive power
Solution Approach 1:
The patent implements feedback by using the detected puff duration as input to control the power supply amount. The control unit measures the actual puff duration and compares it with the standard duration, then adjusts the power supply accordingly - providing standard power for standard duration and reduced power for shorter durations, ensuring optimal aerosol generation without taste degradation.

AI summary
A non-burning type flavor inhaler includes a control unit that controls power supplied from a power source to an atomizer. The control unit controls, in one puff action in a standard mode, controls the power source to supply standard power amount to the atomizer in a duration before a first duration elapses. The control unit, in one puff action in the reduced mode, controls the power source to supply first power amount greater than the standard power amount to the atomizer in a duration before a second duration elapses, and controls the power source to supply second power amount smaller than the first power amount to the atomizer in a duration after the second duration elapses and before a third duration elapses.
