Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an electromagnetic-shielding component is added to protect the metal hearth from magnetic field damage, then the metal hearth is protected from damage, but the internal structure becomes more complicated and heat dissipation capability deteriorates
Solution Approach 1:
The electromagnetic-shielding component is integrated with the base to form an integral structure, merging two previously separate components (shielding component and base) into one unified part, thereby simplifying the overall internal structure while maintaining shielding functionality
Solution Approach 2:
The base is designed to serve multiple functions: it provides structural support, facilitates heat dissipation through integrated channels, and incorporates the electromagnetic-shielding component to protect against magnetic field damage, making the base a multi-functional element
2Object-affected harmful factors
If an electromagnetic-shielding component is added to shield the metal hearth, then magnetic field protection is improved, but heat dissipation capability worsens due to blocked heat pathways
Solution Approach 1:
The electromagnetic-shielding component features a cyclic structure with localized openings that allow heat to pass through specific regions while maintaining shielding functionality in other areas, creating different properties in different parts of the same component
Solution Approach 2:
The cyclic structure of the electromagnetic-shielding component acts as an intermediary that allows heat energy to pass through while still providing magnetic field shielding, mediating between the conflicting requirements of protection and heat dissipation
3Volume of stationary object
If the internal structure is made compact to reduce volume, then the induction cooker size is reduced, but heat dissipation capability deteriorates
Solution Approach 1:
The base incorporates radially distributed reinforcing ribs that create three-dimensional heat dissipation channels, utilizing radial and vertical dimensions to maximize heat dissipation surface area within a compact footprint
4Ease of operation
If the electromagnetic-shielding component and base are made as separate components, then installation flexibility is improved, but assembly complexity increases
Solution Approach 1:
The electromagnetic-shielding component and base are merged into a single integral structure through molding, eliminating the need for separate assembly steps while maintaining the flexibility to install the entire unit as one component
