Solution Approach 1:

The system performs preliminary heating action before the user actually smokes. The gravity sensor detects when the user picks up the electronic cigarette, triggering the heater to warm the liquid in advance. This preliminary action ensures the liquid reaches suitable temperature and fluidity before vaporization is needed, resolving the contradiction between cold temperature conditions and ease of operation.
