Aerosol Consumable Absorbent Wall Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol deposits on the surfaces of tobacco heating devices can prevent proper insertion of consumables and hinder optimal heating, leading to reduced device performance.
Innovation Solution
A consumable with a combination of aerosol generating material and absorbent material, where the absorbent material is exposed to directly contact and absorb deposits on the device's walls, utilizing materials like putty, charcoal, or Sepiolite, and a hydrophilic coating to enhance absorption, while an impermeable coating prevents condensate leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerosol generating material is heated in a closed chamber, then aerosol is generated effectively, but condensate deposits form on chamber walls preventing proper insertion and heating
Solution Approach 1:
An absorbent material is introduced as an intermediary component within the consumable article. This absorbent material contacts the chamber wall and absorbs condensate deposits, acting as a mediator between the heating chamber and the aerosol generating material. The absorbent material includes hygroscopic particles that actively capture and hold condensate, preventing it from interfering with consumable insertion and heating while allowing aerosol generation to proceed effectively.
2Reliability
If absorbent material is added to the consumable, then condensate absorption is improved, but device complexity increases
Solution Approach 1:
The absorbent material is nested within the consumable article structure, specifically positioned to contact the chamber wall during use. The absorbent material can be embedded within the aerosol generating material matrix or incorporated as an inner layer within the consumable's structural components. This nesting approach integrates the condensate absorption function into the existing consumable design without adding separate external components, thereby improving reliability while minimizing increases in device complexity.
