Solution Overview

Problem

Existing cooking apparatuses suffer from excessive smoke production during cooking, which negatively affects the odor and taste of cooked food ingredients.

Innovation Solution

A cooking apparatus that includes a cooking chamber, a heater, and processors configured to control the heater to heat the cooking chamber at a first temperature (≤140°C) for a larger fraction of the cooking time and at a second temperature (higher than 140°C) for a shorter remainder of the cooking time, based on inputted recipe parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cooking chamber is heated at high temperature throughout the cooking time, then the cooking efficiency and food doneness are improved, but excessive smoke production occurs which deteriorates food odor and taste

Engineering Contradiction:
Improvecooking efficiencyVSAvoidsmoke production
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The cooking process is segmented into two distinct temperature phases: a first temperature phase (≤140°C) for the larger fraction of cooking time and a second temperature phase (>140°C) for the remainder. This segmentation allows the cooking process to benefit from both low-temperature smoke-free cooking and high-temperature efficient cooking, resolving the contradiction between productivity and smoke generation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cooking process employs periodic temperature variation, alternating between lower temperature periods (reducing smoke) and higher temperature periods (improving cooking efficiency). The processor dynamically adjusts temperature based on cooking time fractions, creating a periodic thermal action pattern that balances smoke reduction with cooking effectiveness

Inventive Principle:
Principle #19Periodic action

2Object-generated harmful factors

If the cooking chamber is heated at low temperature to reduce smoke, then smoke production and adverse effects on food odor and taste are reduced, but the cooking time increases which reduces productivity

Engineering Contradiction:
Improvesmoke productionVSAvoidcooking time
Core Design Contradiction:
Object-generated harmful factorsVSProductivity

Solution Approach 1:

The cooking process is divided into two temperature segments where the first segment (≤140°C) occupies a larger fraction of time for smoke-free cooking, while the second segment (>140°C) occupies a smaller fraction for rapid finishing. This segmentation ensures that the majority of cooking occurs at smoke-reducing temperatures while a brief high-temperature phase maintains productivity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The temperature parameter is dynamically changed during the cooking process based on the elapsed time and predetermined fractions. The processor adjusts the heating element output to transition between temperature zones, optimizing the balance between smoke reduction and cooking speed by varying the temperature parameter throughout the cooking cycle

Inventive Principle:
Principle #35Parameter changes

AI summary

A cooking apparatus including a cooking chamber for receiving food ingredients. A heater for heating the cooking chamber. An input arrangement to input at least one recipe parameter indicative of an energy requirement for cooking the food ingredients. One or more processors control the heater to heat the cooking chamber at a first temperature less than or equal to 140° C. for a fraction of a cooking time and control the heater to heat the cooking chamber at a second temperature higher than 140° C. for the remainder of the cooking time. The remainder is a further fraction of the cooking time which is less than the fraction. The processors select the cooking time based on the energy requirement, fraction of the cooking time at the first temperature, further fraction of the cooking time at the second temperature. A method for operating the cooking apparatus. A computer program for implementing the method.
