Paper Filter With Harder Core for Heat-Not-Burn Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paper filters in flavor inhalation articles tend to become too soft, affecting the sensation of holding and ease of attachment to a heat-not-burn inhalation device.
Innovation Solution
Incorporating a harder object within the paper filter, such as a paper tube, to maintain the desired hardness and improve the sensation of holding and ease of attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a paper filter is used in a flavor inhalation article, then environmental factors are improved, but the filter section becomes too soft affecting holding sensation and attachment ease
Solution Approach 1:
The patent combines paper filter material with a harder inner core structure to create a composite filter section. The paper filter maintains environmental benefits while the inner core provides structural support and appropriate hardness, resolving the contradiction between environmental friendliness and mechanical strength.
Solution Approach 2:
The patent applies different material properties to different regions of the filter section. The outer paper filter layer maintains softness and environmental benefits, while the inner core structure provides localized hardness and structural support where needed for holding sensation and attachment ease.
2Object-affected harmful factors
If a paper filter is used in a flavor inhalation article, then environmental friendliness is improved, but the ease of attachment to heat-not-burn device deteriorates
Solution Approach 1:
The composite structure of paper filter with inner core provides both environmental benefits and improved attachment characteristics. The inner core structure gives the filter section sufficient rigidity to be easily handled and attached to the heat-not-burn device, while the paper outer layer maintains environmental friendliness.
Solution Approach 2:
By concentrating structural support in the inner core region, the patent enables the filter section to have appropriate rigidity for easy attachment operations, while the outer paper layers maintain their environmental benefits without compromising attachment ease.
