Telescopic Filter Adjuster for Vapour Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heated substrate aerosol generation devices do not provide a user experience that mimics traditional tobacco products, lacking the ability to adjust temperature to individual preferences.
Innovation Solution
A vapour generating article with a filter that includes an adjuster to modify the length of the airflow passageway, allowing users to adjust the temperature of the generated vapour by increasing or decreasing the distance the vapour travels before reaching the user's mouth, using a telescopic or rotatable mechanism, and featuring a reusable design to reduce waste and enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the airflow passageway length is fixed, then the device structure is simple, but the user cannot adjust the vapour temperature to suit their preferences
Solution Approach 1:
The filter incorporates a telescopic adjuster mechanism that allows the airflow passageway length to be dynamically changed by the user. The adjuster includes an inner sleeve and outer sleeve that can slide relative to each other, enabling continuous adjustment of the airflow path length to control vapour temperature according to user preference.
Solution Approach 2:
The adjuster mechanism uses a nested structure where the inner sleeve is positioned within the outer sleeve. This nesting allows the adjuster components to be compact while still providing the functionality of variable airflow path length, reducing the overall space required in the filter structure.
2Ease of operation
If a telescopic adjuster mechanism is added to the filter, then the vapour temperature can be adjusted, but the filter structure becomes more complex
Solution Approach 1:
The adjuster is designed to be manually operated by the user without requiring external power sources or complex control systems. The user directly controls the airflow passageway length by sliding the telescopic mechanism, making the system self-service and eliminating the need for electronic controls or power consumption.
Solution Approach 2:
The patent replaces potential electronic temperature control systems with a purely mechanical telescopic adjuster. This mechanical substitution simplifies the overall system by eliminating electronics, power sources, and associated control circuits, while still achieving the goal of user-adjustable vapour temperature.
3Temperature
If the airflow passageway is shortened, then the vapour remains warmer, but the cooling effect is reduced
Solution Approach 1:
The telescopic adjuster enables dynamic control of the airflow passageway length, allowing users to find the optimal balance between vapour temperature and cooling effect. By adjusting the passageway length, users can control the residence time of vapour in the filter, thereby regulating the degree of cooling while maintaining acceptable temperature levels.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to customize the temperature of the vapour to suit their taste and smoking characteristics, providing a more traditional vaping experience while reducing waste and allowing for more complex temperature control technology within the filter.
Implementation Method 1
an airflow passageway within the filter configured to allow a vapour to flow into the filter through the attachment end from the first end of the body and out of the filter through the mouthpiece end
Implementation Method 2
The adjustor may comprise an inner sleeve portion and an outer sleeve portion and wherein movement of the outer sleeve portion relative to the inner sleeve portion adjusts the length of the airflow passageway
