Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resistance heating mode is used with separate heating unit and liquid transfer material, then heating function is achieved, but the structure becomes complex and cost increases
Solution Approach 1:
The patent merges the heating unit and liquid transfer material into a single integrated atomization heating assembly. The magnetically conductive porous heating unit serves dual functions: as a heating element and as a liquid transfer medium through its porous structure, eliminating the need for separate components and reducing overall device complexity
Solution Approach 2:
The magnetically conductive porous heating unit is designed to perform multiple functions simultaneously: it generates heat through electromagnetic induction and transfers liquid through its porous structure. This multi-functional design simplifies the overall device architecture by consolidating what would traditionally require separate components
2Reliability
If liquid transfer material is attached to porous material, then liquid transfer function is guaranteed, but drying burning occurs when liquid transfer material separates from porous material
Solution Approach 1:
The heating unit and liquid transfer material are merged into a single integrated porous structure. The magnetically conductive porous heating unit inherently combines liquid transfer capability through its porous network with heating function, eliminating the interface between separate components that could lead to separation and drying burning
Solution Approach 2:
The patent uses composite material structure where magnetically conductive particles are embedded within a porous matrix material. This composite structure ensures that the liquid transfer pathways remain intact while providing uniform heating, preventing the separation issues that occur with attached liquid transfer materials
3Power
If resistance heating is used, then heating is achieved, but heating is limited by resistance of heating unit and conductor sectional area
Solution Approach 1:
The patent replaces traditional resistance heating (which relies on electrical current flow through resistive elements) with electromagnetic induction heating. The magnetically conductive porous heating unit generates heat through induced eddy currents from an alternating magnetic field, eliminating the need for direct electrical connections and external power supply wiring
Solution Approach 2:
The heating mechanism is changed from resistance-based to electromagnetic induction-based. By using magnetically conductive materials with appropriate magnetic properties, the system achieves heating without being constrained by electrical resistance limits or conductor cross-sectional area requirements
