Cooking vessel and cooking-vessel system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking vessels face issues with being non-dishwasher safe and inefficient heat transfer when equipped with temperature sensors and electronic units.
Innovation Solution
A cooking vessel design featuring a container with integrated heating elements, temperature sensors, and an electronic unit, where the components are connected via shielded cables and a power supply, allowing for efficient energy use and dishwasher safety through insulation and wireless data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor and electronic unit are mounted in the base of the vessel connected via electrical conductor, then temperature control is achieved, but the vessel becomes non-dishwasher safe
Solution Approach 1:
The system is divided into two separable parts: a dishwasher-safe container (vessel) and an electronics unit with temperature sensor and heating element. The container can be removed and cleaned in the dishwasher independently, while the electronics unit remains separate. This segmentation resolves the contradiction by allowing the vessel to be dishwasher-safe while still achieving temperature control through the separate electronic components.
2Ease of manufacture
If dishwasher-safe inserts are used in a heatable housing with temperature sensor and electronic unit, then dishwasher safety is achieved, but heat transfer from housing to insert is not energy-efficient
Solution Approach 1:
The heating element is integrated directly into the base of the container rather than being separated in an external housing. This merging of the heating function with the container structure eliminates the intermediate housing layer, enabling direct heat transfer to the food or liquid inside the vessel. This resolves the contradiction by maintaining dishwasher safety while achieving energy-efficient heat transfer through direct contact heating.
