Solution Overview
Problem
Existing methods for producing containers for cooking food are laborious and expensive, particularly when creating a bottom suitable for use on electromagnetic induction plates while also maintaining stability and thermal efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coupling methods (moulding, brazing, impact bonding) are used to attach ferromagnetic bottom to non-ferromagnetic main body, then good technical result is achieved for induction plate use, but the process becomes laborious and expensive
Solution Approach 1:
The patent merges the bottom and main body into a single monoblock structure made of ferromagnetic material, eliminating the need for separate coupling operations (moulding, brazing, or impact bonding). This integration resolves the contradiction by maintaining the ferromagnetic property needed for induction plates while simplifying the manufacturing process into a single casting operation.
Solution Approach 2:
The patent uses composite material structure with a ferromagnetic outer layer (bottom and outer surface) and a non-ferromagnetic inner core, created through selective breeding or coating during the casting process. This allows the container to be magnetically responsive for induction cooking while maintaining structural integrity and simplifying manufacturing compared to traditional multi-step assembly methods.
2Use of energy by moving object
If ferromagnetic material is used for the bottom to enable induction plate compatibility, then thermal efficiency is improved, but the bottom becomes prone to deformation during use
Solution Approach 1:
The patent employs a composite structure where the ferromagnetic material forms the bottom and outer surface for thermal efficiency and induction compatibility, while the inner core consists of non-ferromagnetic material providing structural stability and resistance to deformation. This layered composite approach resolves the contradiction between magnetic responsiveness and structural rigidity.
Solution Approach 2:
The patent applies different material properties to different parts of the container: the bottom and outer surface use ferromagnetic material optimized for thermal conduction and magnetic interaction, while the inner body uses non-ferromagnetic material optimized for structural stability. This local differentiation of material properties resolves the contradiction between thermal efficiency and deformation resistance.
3Adaptability or versatility
If complex multi-step processing is used to create ferromagnetic bottom, then induction plate compatibility is achieved, but production cost increases
Solution Approach 1:
The patent combines multiple functions (structural formation, ferromagnetic property acquisition, and surface finishing) into a single continuous casting process. The ferromagnetic material is introduced during casting itself through selective breeding or coating techniques, eliminating the need for separate attachment operations and reducing production costs while maintaining induction plate compatibility.
Solution Approach 2:
The patent performs the ferromagnetic material application during the initial casting stage rather than as a subsequent separate operation. By incorporating the ferromagnetic property formation into the primary manufacturing process, the patent eliminates multiple processing steps and reduces overall production cost while ensuring induction plate compatibility from the outset.
