Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The patent applies dynamics by making the output power adjustable rather than fixed. The controller dynamically adjusts the output power of the battery cell based on detected ambient temperature, using different power levels in different temperature conditions to optimize both heating performance and battery longevity
Solution Approach 2:
The patent changes the operating parameters of the battery cell based on ambient temperature. By adjusting the output power parameter according to temperature conditions, the system maintains effective heating while extending battery life and increasing the number of usable aerosol products
2Duration of action of moving object
If the output power is reduced to extend battery life, then more aerosol products can be maintained, but the heating assembly may not reach the preset preheating temperature
Solution Approach 1:
The system changes the output power parameter based on ambient temperature conditions. In colder temperatures where more power is needed for heating, the controller adjusts power accordingly, while in warmer temperatures it reduces power to conserve battery capacity, thus maintaining both heating effectiveness and extended battery life
3Device complexity
If a fixed output power is used regardless of ambient temperature, then the device structure remains simple, but the battery performance varies significantly with temperature, affecting the number of aerosol products
Solution Approach 1:
The patent implements feedback by using the controller to detect ambient temperature and adjust the battery cell's output power accordingly. This closed-loop control system automatically adapts to temperature changes, extending battery life and increasing the number of usable aerosol products without requiring complex manual intervention
Solution Approach 2:
The system transitions from a static fixed-power design to a dynamic adaptive-power design. The controller enables real-time adjustment of output power based on temperature feedback, optimizing battery performance across varying environmental conditions while maintaining relatively simple device architecture
