Solution Overview
Problem
Modern cookware with electronic components is often affected by external interference such as electromagnetic fields from induction coils, leading to unreliable functionality and an unappealing design due to bulky shielding units.
Innovation Solution
Incorporating a shielding body within the handle device of the cookware, made from aluminum with a thickness of at least 0.7 mm, which is partially enclosed by the handle body to protect electronic assemblies from electromagnetic interference, while maintaining a visually appealing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shielding unit is added to protect electronic components from electromagnetic interference, then the reliability of electronic components is improved, but the appearance and compactness of the cookware deteriorates due to bulky external shielding
Solution Approach 1:
The patent combines the shielding function with the existing handle body structure. The handle body is designed to enclose the electronic assembly, and the shielding unit is integrated within this enclosed space, merging the protective shielding function with the structural handle function. This eliminates the need for separate bulky external shielding while maintaining electromagnetic interference protection.
Solution Approach 2:
The shielding unit is nested within the handle body structure, which itself is received on the cookware base body. The electronic assembly is positioned within the enclosed space of the handle body, and the shielding unit surrounds the electronic assembly from within this space. This nested arrangement provides effective shielding while maintaining a compact and aesthetically pleasing external appearance.
2Reliability
If a shielding unit is added to protect electronic components from electromagnetic interference, then the reliability of electronic components is improved, but the device complexity increases
Solution Approach 1:
The shielding unit is combined with the handle body structure, eliminating the need for separate shielding components. The handle body serves dual functions: providing structural support for the cookware and providing electromagnetic shielding for the electronic assembly. This integration reduces the total number of parts and simplifies the overall device complexity.
Solution Approach 2:
The handle body is designed with multi-functionality: it provides mechanical support for holding the cookware, structural attachment to the base body, and electromagnetic shielding for the electronic components. By making the handle body universal in its functions, the patent avoids adding separate dedicated shielding structures, thereby reducing device complexity.
3Adaptability or versatility
If electronic components are added to assist users in cooking processes, then the functionality and user assistance are improved, but the susceptibility to electromagnetic interference increases
Solution Approach 1:
The shielding unit is positioned to preemptively block electromagnetic interference before it can reach the electronic assembly. The shielding material is arranged to create a protective barrier that counteracts the harmful electromagnetic fields generated by induction cooktops, preventing interference with the electronic components' operation.
Solution Approach 2:
The patent uses conductive or magnetic shielding materials that can safely channel or dissipate electromagnetic energy. The shielding unit converts the potentially harmful electromagnetic interference into manageable energy flows that do not disrupt the electronic assembly, effectively transforming the harmful factor into a controllable condition.
