Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-layer electrode structure is used, then the device complexity is reduced, but the heating efficiency deteriorates
Solution Approach 1:
The electrode structure is segmented into multiple layers (positive electrode layer and negative electrode layer) arranged alternately. This segmentation allows each layer to contribute to heating independently, significantly improving heating efficiency compared to a single-layer structure while maintaining manageable device complexity through modular design.
Solution Approach 2:
The electrode structure transitions from a one-dimensional single-layer configuration to a multi-dimensional stacked arrangement of positive and negative electrode layers. This dimensional change increases the effective heating surface area and creates multiple heating zones, thereby enhancing overall heating efficiency without proportionally increasing device complexity.
2Productivity
If multiple conductors are added to enhance heating, then heating efficiency is improved, but device complexity increases
Solution Approach 1:
Multiple conductors (central conductor, internal conductor, external conductor) are merged into a single integrated electrode assembly where positive and negative electrode layers are stacked alternately. This merging approach achieves enhanced heating efficiency through multiple conductors while controlling device complexity by combining them into a unified modular structure.
Solution Approach 2:
The electrode structure employs a nested configuration where the internal conductor is positioned within the central conductor, and the external conductor surrounds the central conductor. This nesting arrangement allows multiple conductors to be integrated in a space-efficient manner, improving heating efficiency without proportionally increasing device complexity.
