Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If the output power of the battery cell is increased to maintain heating performance, then the heating assembly can reach the preset preheating temperature, but the battery cell's electric capacity depletes faster, reducing the number of aerosol products that can be maintained

Engineering Contradiction:
