Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If resistive heating method is used to heat the aerosol-forming medium, then the heating component can vaporize the medium to form aerosol, but the energy conversion efficiency is low

Engineering Contradiction:

Improveenergy conversion efficiencyVSAvoidenergy loss

Core Design Contradiction:

Use of energy by moving objectVSLoss of energy

Solution Approach 1:

The patent replaces the traditional resistive heating method with electromagnetic induction heating. The heating component includes a coil that generates an alternating magnetic field to induce eddy currents in the aerosol-forming medium, which generates heat through electromagnetic induction rather than direct electrical resistance. This substitution of heating mechanism significantly improves energy conversion efficiency by directly coupling electromagnetic energy to the medium.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the heating parameter from resistive heating (Joule heating) to electromagnetic induction heating. By altering the fundamental heating mechanism parameter, the system achieves higher energy conversion efficiency. The coil operates at specific frequencies to optimize electromagnetic coupling with the medium, transforming the heating parameter to resolve the energy efficiency contradiction.

2Use of energy by stationary object

If resistive heating method is used, then the heating component can vaporize the aerosol-forming medium, but the heat conduction efficiency is low

Engineering Contradiction:

Improveheat conduction efficiencyVSAvoidheat loss

Core Design Contradiction:

Use of energy by stationary objectVSLoss of energy

Solution Approach 1:

The patent substitutes resistive heating with electromagnetic induction heating, where the coil generates an alternating magnetic field that directly induces eddy currents within the aerosol-forming medium. This eliminates the need for heat conduction from an external heating element to the medium, as the heat is generated internally within the medium itself through electromagnetic induction, thereby dramatically improving heat conduction efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Core Design Contradiction:

Solution Approach 1:

The patent replaces resistive heating with electromagnetic induction heating, where the alternating magnetic field penetrates the aerosol-forming medium uniformly and induces eddy currents throughout the medium. This results in uniform internal heat generation across the entire medium volume, eliminating the temperature gradients and hot spots that occur with resistive heating methods, thereby achieving uniform heating and high aerosol quality.
