Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If combustion is used to heat aerosol precursor, then high temperature is achieved, but combustion byproducts are generated
Solution Approach 1:
The patent replaces the mechanical/chemical combustion system with an electromagnetic induction heating system. The induction transmitter generates an oscillating magnetic field that induces eddy currents in the heating element, which then heats the aerosol precursor through resistive heating without combustion, eliminating harmful combustion byproducts while achieving the required temperature.
Solution Approach 2:
The patent changes the heating mechanism from chemical combustion to electromagnetic induction heating. This parameter change allows precise control of heating temperature through electrical parameters (frequency, power) while avoiding the uncontrolled chemical reactions of combustion, thus eliminating harmful byproducts.
2Duration of action of moving object
If non-rechargeable battery is used, then device structure is simple, but usability duration is limited
Solution Approach 1:
The patent implements a rechargeable power system where the battery can be recharged multiple times through induction charging. Instead of discarding the battery after single use, the system recovers energy by receiving electromagnetic fields from the induction transmitter, converting them to electrical energy, and storing them in the battery, thereby extending usability duration while managing the increased structural complexity.
3Use of energy by moving object
If induction charging system is added, then power supply efficiency is improved, but device complexity increases
Solution Approach 1:
The patent introduces an induction receiver as an intermediary component that facilitates wireless power transfer. The receiver contains a coil that couples with the induction transmitter's magnetic field, converting electromagnetic energy to electrical energy through electromagnetic induction, and then rectifies and stores the energy in the battery, improving power supply efficiency while managing the added structural complexity.
