Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single-piece heating mode with large heating area is used, then the heating coverage is improved, but the temperature distribution becomes non-uniform causing burning smell in middle region and insufficient atomization in peripheral region
Solution Approach 1:
The heating assembly is divided into multiple independent heating cores (first heating core, second heating core, etc.) instead of using a single large heating element. Each heating core has its own heating wire and liquid-conducting holes, creating separate heating zones that can be controlled independently to achieve uniform temperature distribution across the entire heating surface.
Solution Approach 2:
Each heating core is designed with specific liquid-conducting holes positioned to deliver liquid precisely to the heating wire location. This ensures that each local heating zone receives adequate liquid supply and maintains optimal temperature, preventing both burning (excessive heat) and insufficient atomization (insufficient heat) in different regions.
2Device complexity
If a single heating core is used, then the structure is simple, but the atomization uniformity deteriorates due to thermal radiation causing higher temperature in middle region
Solution Approach 1:
The heating assembly is divided into multiple independent heating cores (first heating core, second heating core, etc.) instead of using a single large heating element. Each heating core has its own heating wire and liquid-conducting holes, creating separate heating zones that can be controlled independently to achieve uniform temperature distribution across the entire heating surface.
Solution Approach 2:
The porous liquid-conducting material body acts as an intermediary between the liquid reservoir and the heating wires. It delivers liquid uniformly to multiple heating cores through specifically positioned holes, ensuring each heating zone receives adequate liquid supply for uniform atomization while the heating cores themselves act as intermediaries to distribute heat evenly across the heating surface.
