Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If double-sided tape is used to attach the metal plate to the cabinet, then the metal plate can be fixed, but the foaming agent can infiltrate between the metal plate and the cabinet
Solution Approach 1:
The patent replaces the mechanical attachment system (double-sided tape) with a magnetic field-based system. Magnets are embedded in the foaming mold to generate magnetic attraction forces that hold the metal plate firmly against the cabinet surface, creating a tighter seal that prevents foaming agent infiltration while eliminating the need for adhesive tapes.
Solution Approach 2:
The patent changes the attachment mechanism from chemical adhesion (tape) to magnetic attraction. By adjusting magnetic field strength and distribution, the system achieves both secure attachment and improved sealing, preventing foaming agent infiltration more effectively than mechanical tape attachment.
2Stability of the object's composition
If the metal plate is attached via double-sided tape, then it can be fixed, but the position of the metal plate cannot be stably maintained
Solution Approach 1:
The patent replaces the unreliable mechanical tape attachment with a magnetic field-based positioning system. The magnets in the foaming mold generate consistent magnetic attraction forces that stably maintain the metal plate's position throughout the foaming process, preventing displacement and ensuring reliable attachment.
Solution Approach 2:
The magnetic attachment system is self-adjusting and self-stabilizing. The magnetic field automatically maintains optimal contact between the metal plate and cabinet surface without requiring external intervention, ensuring consistent position stability and attachment reliability throughout the foaming process.
3Ease of manufacture
If the metal plate is not in close contact with the cabinet, then the attachment is easier, but the heater performance deteriorates
Solution Approach 1:
The patent uses magnetic attraction forces to achieve close contact between the metal plate and cabinet surface, ensuring optimal thermal contact for heater performance. The magnetic system maintains consistent pressure and contact area throughout the foaming process, eliminating the need for complex mechanical pressing mechanisms while ensuring reliable thermal coupling.
4Object-affected harmful factors
If a magnet is used to bring the metal plate into close contact, then the foaming agent infiltration is prevented, but the device complexity increases
Solution Approach 1:
The patent merges the magnetic attachment function directly into the foaming mold structure. Magnets are embedded within the mold body, combining the foaming function and the metal plate attachment function into a single integrated device, thereby preventing foaming agent infiltration without significantly increasing overall system complexity.
