Solution Overview

Problem

Existing electronic cigarettes and vaporizers fail to replicate the sensory experience of traditional smoking, including the feel and sound of burning tobacco, and are bulky, lacking the convenience of a rolled cigarette.

Innovation Solution

An electronic cigarette filter with a pre-rolled cigarette integrated into a compact design, featuring a diminutive size, auto-draw activation, and a ceramic air-flow cap, allowing for simultaneous smoking of both aerosolized liquid and burnt leaf material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a vaporizer is used to provide aerosolized liquid, then the smoking experience is enhanced with vaporization, but the device becomes bulky and loses the feel of holding a real cigarette

Engineering Contradiction:
Improvevaporization capabilityVSAvoiddevice bulk
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent merges the vaporizer functionality with a pre-rolled cigarette into a single integrated unit. The cigarette is pre-rolled onto the filter body with the tobacco product positioned to be heated by the vaporization element, combining two separate smoking experiences into one compact device that maintains the feel of a traditional cigarette.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cigarette is nested onto the filter body, with the tobacco product positioned inside the filter structure. The rolling paper is rolled onto the first end of the filter body, creating a compact nested configuration where the cigarette fits within the vaporizer housing, significantly reducing overall device bulk.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a rolled cigarette is attached to a vaporizer, then both burning tobacco and aerosolized liquid can be smoked, but the device becomes even more bulky and unwieldy

Engineering Contradiction:
Improvedual smoking capabilityVSAvoiddevice handleability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The cigarette is pre-rolled onto the filter body before use, with the rolling paper already positioned and sealed against the exterior surface. This preliminary preparation eliminates the need for users to attach a separate rolled cigarette to a vaporizer, simplifying the operation to simply inhaling through the mouthpiece while maintaining dual smoking capability.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If traditional e-cigarettes are used, then aerosolized liquid can be produced, but the experience of burning tobacco and the feel of a light cigarette are lost

Engineering Contradiction:
ImproveaerosolizationVSAvoidloss of smoking experience
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent merges the vaporizer functionality with a pre-rolled cigarette into a single integrated unit. The cigarette is pre-rolled onto the filter body with the tobacco product positioned to be heated by the vaporization element, combining two separate smoking experiences into one compact device that maintains the feel of a traditional cigarette.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Provides a satisfying smoking experience reminiscent of traditional cigarettes while minimizing bulkiness, enhancing user interaction, and offering customizable smoke mixing.

Implementation Method 1

an auto draw device adapted to activate a heating element to heat a liquid into an aerosol

Methodology Applied
Scientific EffectVaporization: Evaporation

Implementation Method 2

an air-flow cap disposed in the rolling material attachment portion, where the air-flow cap includes a plurality of openings leading into the cylindrical body, where at least one of the openings directs to a channel adapted to restrict a smoke flowing into the cylindrical body

Methodology Applied
Scientific EffectFlow restriction: Pressure Gradient

AI summary

An electronic filter is adapted for having a rolling material containing a leaf product rolled onto an exterior surface of the electronic filter where the electronic filter includes a liquid to be aerosolized and mixed with a smoke from burning the leaf product. The electronic filter can be pre-rolled into a cigarette with a leaf product and ready for consumption in a single use or can be adapted for multiple uses. The electronic filter includes a cylindrical body including a mouthpiece portion and a rolling material attachment portion, where the mouthpiece portion includes a mouthpiece having an orifice leading into the cylindrical body, and where the rolling material attachment portion includes an exterior surface of the cylindrical body adapted to have a rolling material rolled onto and sealed against the exterior surface. The electronic filter also includes a battery, storage tank and auto draw device.
