Food Container Heating Element Water Injection Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food containers with heating elements are inconvenient for injecting water to generate heat, often requiring users to transfer heated foods or have complex structures that increase manufacturing costs.
Innovation Solution
A food container design featuring an outer container with a first extension part for water inflow and an inner container with a second extension part for coupling, allowing water to be injected without removing the inner container, and a pressure valve for vapor discharge, maintaining the heating element's stability within the outer container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner container is removed to inject water into the main body, then water can be injected for heating, but the operation becomes inconvenient and complex
Solution Approach 1:
The inner container is designed with an extension part that nests into the main body's extension part, allowing the inner container to remain in place while enabling water injection through the heating element. This nested structure eliminates the need to remove the inner container for water injection, resolving the contradiction between ease of operation and device complexity.
2Reliability
If the heating element and water reaction space is separated from food container space, then heating reaction can occur, but the structure becomes complex
Solution Approach 1:
The extension parts of the inner container and main body are designed to overlap and seal together, merging the heating element reaction space with the food container space through a sealed connection. This allows the heating reaction to occur effectively while maintaining a simple integrated structure, resolving the contradiction between heating reliability and structural complexity.
3Device complexity
If the heating element stability is ensured without additional supporting elements, then the structure is simplified, but the heating element may become unstable
Solution Approach 1:
The main body and inner container extension parts are designed to overlap and seal together, creating a self-supporting structure that inherently stabilizes the heating element without requiring additional supporting elements. The sealed connection between extension parts provides structural stability, resolving the contradiction between device complexity and heating element stability.

AI summary
A food container using a heating element, which container enhances convenience since a user can simply inject water toward the heating element by opening an inflow passage of an outer container without removing an inner container, and can keep the heating element stable in a simplified structure since a space containing the heating element inside the outer container and a space containing water are formed to be divided by a protrusion jaw but to communicate with each other.
