Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a porous base is used in the atomization core, then liquid substrate storage and supply is enabled, but local insufficient liquid supply occurs leading to high temperature and carbon deposition
Solution Approach 1:
The patent introduces a thermally conductive layer with different porosity (80-99%) compared to the porous base (30-80%), creating local quality differences. This layer is specifically positioned between the heating element and the porous base to address local liquid supply deficiencies, allowing uniform liquid distribution without compromising overall storage capacity
Solution Approach 2:
The thermally conductive layer acts as an intermediary between the porous base and the heating element. It mediates the liquid supply by providing additional capillary channels that deliver liquid directly to the heating zone, preventing local depletion while maintaining overall system functionality
2Quantity of substance
If the porous base porosity is increased to improve liquid supply, then liquid delivery is enhanced, but thermal conductivity decreases leading to poorer heat distribution
Solution Approach 1:
The patent segments the porous base into two functional layers: the original porous base (30-80% porosity) for liquid storage and the thermally conductive layer (80-99% porosity) for heat distribution. This segmentation allows each layer to optimize its specific function without compromising the other, resolving the contradiction between liquid delivery and thermal conductivity
Solution Approach 2:
The patent creates a composite structure combining the porous base material with the thermally conductive layer material. This composite approach allows the system to simultaneously achieve both liquid supply capability and thermal conductivity by leveraging the complementary properties of the two materials in a layered configuration
