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

VSEngineering 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

Engineering Contradiction:
Improvetemperature controlVSAvoiddishwasher safety
Core Design Contradiction:
Measurement precisionVSEase of manufacture

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvedishwasher safetyVSAvoidheat transfer efficiency
Core Design Contradiction:
Ease of manufactureVSLoss of energy

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.

Inventive Principle:
Principle #5Merging (Combining)
