Inductively Heatable Lunch Container for Safe Child Food Warming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lunch containers are not suitable for safely heating and storing foods and drinks for small children and babies, and existing baby bottles and coffee beakers are limited in their functionality for this purpose.
Innovation Solution
A lunch container designed like a drinks bottle with a thermally insulating outer casing and an inductively heatable inner cylinder, equipped with safety features such as handles and a protective cap, allowing wireless heating and cooling, and featuring a transparent slit for filling level indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional lunch container with hinged lid and zip fastener is used, then it can store and transport food, but it cannot safely heat food and drinks for small children and babies
Solution Approach 1:
The container is divided into two distinct parts: an inner container that contacts the food/drink and an outer container that provides thermal insulation. This segmentation allows the inner container to be heated while the outer container remains cool to the touch, enabling heating functionality while preventing burns.
Solution Approach 2:
The thermally insulating outer container acts as an intermediary between the heated inner container and the user's hand. This intermediary layer blocks heat transfer, allowing the user to safely hold and handle the container even when the contents are hot.
2Adaptability or versatility
If baby bottles are used for heating drinks, then they can heat milk, but they cannot heat paste-like foods and are not suitable for direct consumption by small children
Solution Approach 1:
The container is designed to be multi-functional, serving as both a storage container and a heating device for various types of food and drinks. The wide mouth opening allows paste-like foods to be easily added and consumed directly, while the heating functionality works for both liquids and semi-solids, replacing the need for separate baby bottles and food containers.
3Adaptability or versatility
If coffee beakers are used for heating drinks, then they can heat beverages, but they are only designed for hot drinks and adults, not for children's food and drinks
Solution Approach 1:
The container features an asymmetric design with a wide mouth opening that is specifically suited for children's needs - allowing easy addition of paste-like foods and direct consumption. This asymmetric opening design differentiates it from traditional symmetric coffee beakers and makes it adaptable for both food and drink purposes for children.
4Object-affected harmful factors
If wireless inductive heating is implemented, then the outer casing remains cool and safe to handle, but the container requires power supply connections or switches that complicate the design
Solution Approach 1:
The container uses wireless inductive heating technology, replacing traditional mechanical heating elements and control switches. The heating is activated by placing the container on a charging/heating base that provides power inductively, eliminating the need for buttons, switches, or visible connections on the container itself, thus maintaining simplicity while ensuring safety.

AI summary
A container for storing, transporting, and heating foods and drinks, in particular foods and drinks prepared for consumption by small children and babies. It is intended to be able to be used simply and safely by small children. The container includes a cylindrical outer casing with a closed base, the upper covering surface of which can be closed with a lid. A heatable inner cylinder with a base is arranged in the outer casing.
