Double wall cooking vessel with induction element insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional induction cooking requires ferrous materials, limiting its application to non-ferrous cooking vessels, as electromagnetic radiation cannot efficiently heat non-ferrous materials.
Innovation Solution
Incorporating ferrous elements into or around non-ferrous cooking vessels, allowing electromagnetic radiation to heat these elements, which then transfer heat to the food, enabling induction cooking in vessels made of non-ferrous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If ferrous materials are used for cooking vessels, then induction heating is efficient, but material selection is limited
Solution Approach 1:
The cooking vessel is divided into two functional parts: a non-ferrous outer vessel structure and a separate ferrous induction heating element. This segmentation allows the vessel to maintain non-ferrous material properties while incorporating ferrous heating capability through the insertable element.
Solution Approach 2:
A ferrous induction heating element acts as an intermediary between the electromagnetic radiation source and the non-ferrous cooking vessel. The heating element absorbs electromagnetic energy and transfers it as thermal energy to the vessel and contents, enabling induction heating of non-ferrous materials.
2Ease of manufacture
If ferrous cooking vessel cover is used with induction heating elements, then targeted heating is achieved, but device complexity increases
Solution Approach 1:
The ferrous cooking vessel cover serves multiple functions: it acts as a structural cover, an induction heating surface, and a heat transfer medium. By making the cover itself induction-compatible, the system achieves targeted heating without adding separate heating mechanisms.
Solution Approach 2:
The induction heating capability is extended from the traditional bottom surface to the top cover surface, adding a new dimensional aspect to heat application. This allows heating from above while the vessel remains on a conventional stovetop.

AI summary
A cooking vessel system includes a double wall cooking vessel that includes a bottom wall, an inner side wall, and an outer side wall. The cooking vessel also includes a plurality of dividers that extend between the inner side wall and the outer side wall. The plurality of dividers form one or more slots between the inner side wall and the outer side wall. The system also includes an induction element configured to fit into a slot of the one or more slots such that the induction element is positioned at least partially between the inner side wall and the outer side wall.
