Engineering Contradiction Analysis
1Productivity
If conventional electric heating coils are used, then the heating mechanism is simple, but the heating efficiency of metal carriers is low
Solution Approach 1:
The patent replaces conventional electric heating coils with an electromagnetic induction system consisting of an induction coil, glass pipe, cup-shaped electrodes, and battery assembly. This substitution transitions from direct resistive heating to electromagnetic induction heating, significantly improving heating efficiency for metal carriers while accepting increased structural complexity
Solution Approach 2:
The patent employs multiple batteries connected in series to generate high-voltage alternating current, transforming the electrical parameters (voltage, current frequency) to optimize electromagnetic induction effectiveness. This parameter change enables efficient heating that conventional low-voltage heating coils cannot achieve
2Power
If high-frequency alternating current is generated through multiple batteries, then the induced magnetic field strength increases, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent divides the power generation system into multiple separate battery units connected in series, allowing each battery to be manufactured and assembled independently. This segmentation enables achievement of high voltage and power output while maintaining manufacturing feasibility through modular assembly
Solution Approach 2:
The patent implements a nested structure where the glass pipe containing metal carriers is placed within the induction coil, which is positioned on the control plate assembly. This nested arrangement optimizes space utilization and electromagnetic field concentration, achieving strong induction effects within a compact manufactured structure
