Solution Overview

Problem

Smokers using their own smokable filler in preformed smoking shells face the issue of heat emission from the filter tip, which can cause discomfort due to radial heat transmission during smoking.

Innovation Solution

Incorporating a longitudinal insulating member within the smoking shell that blocks the radial transmission of heat from the filter tip, using materials like thermoplastic synthetic resins or corrugated paper with air gaps, to reduce heat transfer to the user's fingers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a filter tip is inserted into the smoking shell, then the filtering function is improved, but heat is transmitted radially to the user's fingers causing discomfort

Engineering Contradiction:
Improveheat transmission to fingersVSAvoidfiltering function
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

An insulating member is introduced as an intermediary element between the filter tip and the smoking shell wall. This insulating member blocks radial heat transmission from the filter tip to the user's fingers while maintaining the filtering function, thereby resolving the contradiction between heat protection and filtering effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The harmful heat transmission function is extracted from the system by removing the direct thermal pathway between the filter tip and the shell wall. The insulating member effectively separates the heat flow path, allowing the filtering function to remain while eliminating the harmful thermal effect.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If the insulating member extends the full longitudinal length of the smoking shell, then heat insulation is maximized, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveheat insulation effectivenessVSAvoidinsulating member structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The insulating member is strategically positioned only in the region where heat insulation is most needed - around the filter tip insertion area and extending partially along the shell. This localized approach provides sufficient heat protection without requiring the insulating member to span the entire longitudinal length, thereby reducing structural complexity and manufacturing difficulty while maintaining effective heat insulation.

Inventive Principle:
Principle #3Local quality
