Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If traditional combustion heating is used, then high temperature vaporization is achieved, but harmful substances including carcinogens are released

Engineering Contradiction:

Improveheating temperatureVSAvoidharmful substances

Core Design Contradiction:

TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent changes the heating parameter from combustion temperature to controlled conduction temperature, maintaining vaporization effectiveness while eliminating harmful combustion byproducts. The heating element operates at a controlled temperature that vaporizes plant materials without reaching combustion thresholds.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the chemical combustion process with a controlled thermal conduction system. Instead of burning plant materials to generate heat, an electric heating element directly conducts heat to the material, eliminating the need for combustion and associated harmful emissions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Use of energy by moving object

If direct contact heating is used, then efficient heat transfer is achieved, but uneven heating and overheating occur

Engineering Contradiction:

Improveheat transfer efficiencyVSAvoidheating uniformity

Core Design Contradiction:

Use of energy by moving objectVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating different heating zones through the air gap structure. Areas in direct contact with the heating element receive conductive heat, while areas separated by the air gap receive convective heat, ensuring uniform temperature distribution across the plant material without overheating any single location.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The air gap acts as an intermediary between the heating element and plant material, mediating heat transfer through a combination of conduction and convection. This intermediate layer prevents direct overheating while maintaining efficient heat transfer, solving the contradiction between heat efficiency and heating uniformity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If frangible section deformation is implemented, then air gap formation is achieved, but device complexity increases

Engineering Contradiction:

Improveheating controlVSAvoidcartridge structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The frangible section is designed to automatically deform and create the air gap through the mechanical action of insertion itself, without requiring external actuators or complex control mechanisms. The structure serves its own function of air gap formation, minimizing added complexity while achieving precise heating control.

Inventive Principle:

Principle #25Self-service

AI summary

A disposable consumable with tobacco, hemp and/or cannabis therein is heated in a receivor allowing conduction and convection. The consumable when inserted into a heating chamber via a receivor and a spacer formed on the consumable separates a portion of the consumable from the receivor wall forming one or more regions of air. In some instances slots or uneven portions of the spacer form air passageways with in the receivor between the consumable and the receivor inner wall.
