Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional heating element is used, then the atomization function is achieved, but uneven heating occurs causing inconsistent atomization temperature and poor mouthfeel
Solution Approach 1:
The heating element adopts different resistance values in different regions (first resistance value in one region, second resistance value in another region) to create non-uniform heating distribution. This local quality variation compensates for heat loss patterns, ensuring uniform temperature distribution across the heating surface and consistent atomization temperature.
Solution Approach 2:
The invention changes the electrical resistance parameter spatially across the heating element. By adjusting resistance values in different regions, the power distribution is optimized to achieve uniform heating, directly addressing the temperature consistency issue in atomization.
2Productivity
If heating temperature is increased to improve atomization efficiency, then atomization performance improves, but e-liquid decomposes into toxic substances endangering user health
Solution Approach 1:
By creating regions with different resistance values, the heating element distributes heat more evenly across the surface, preventing localized overheating. This ensures e-liquid is heated to the optimal atomization temperature without exceeding the decomposition threshold, eliminating toxic substance formation while maintaining efficient atomization.
Solution Approach 2:
The invention converts the potential harm of overheating into benefit by using controlled resistance variation to prevent temperature spikes. The non-uniform resistance distribution actually creates a self-regulating effect that protects against e-liquid decomposition while maintaining high atomization efficiency.
3Manufacturing precision
If a simple heating element structure is used, then manufacturing is easier, but heating uniformity is poor leading to inconsistent atomization
Solution Approach 1:
The heating element incorporates regions with different resistance values to achieve uniform heating. This local quality approach allows the use of relatively simple manufacturing processes (such as selective plating or material deposition) while still achieving the complex heating uniformity required for consistent atomization performance.
