Solution Overview

Problem

In commercial cooking appliances, simultaneous loading of various products with different amounts and tray configurations leads to suboptimal cooking times due to temperature fluctuations, altered air movements, and humidity changes, resulting in inconsistent cooking results.

Innovation Solution

The method optimizes cooking processes by adjusting parameters such as cooking time, temperature, humidity, and air speed before, during, or at the start of the cooking process, using a formula to calculate new cooking times based on the number of trays and product amounts, ensuring consistent quality across mixed loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple products with different amounts are loaded simultaneously into the cooking space, then the cooking appliance can process various products in one cycle (improving productivity), but the cooking times stored for individual cooking programs are no longer optimally appropriate due to temperature fluctuations, altered air movements, and humidity changes (worsening manufacturing precision)

Engineering Contradiction:
Improvecooking capacityVSAvoidcooking time accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system dynamically adjusts cooking parameters (time, temperature, humidity, air speed) based on the actual product load configuration. The control unit calculates updated cooking times using a formula that considers the number of trays and base cooking parameters, allowing the cooking program to adapt in real-time to mixed loading conditions rather than relying on fixed stored values

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the cooking parameters (time, temperature, humidity, air speed) based on the detected product load. The control unit modifies at least one cooking parameter using a calculation that incorporates the number of trays and base cooking parameters, ensuring optimal cooking conditions for each product regardless of the mixed loading configuration

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the cooking space is loaded with variable amounts of products on different number of trays, then the appliance can accommodate diverse cooking needs (improving adaptability), but the different amounts of cold cooking material cause increased fall in temperature, altered air movements, and altered humidity values (worsening stability)

Engineering Contradiction:
Improveloading flexibilityVSAvoidcooking atmosphere stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The control unit performs preliminary calculations of updated cooking parameters before the cooking process begins. By determining the adjusted cooking time and other parameters in advance based on the detected tray configuration and product amounts, the system prepares compensation measures for the expected temperature drops and humidity changes caused by loading variable amounts of cold cooking material

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the detected product load configuration to adjust cooking parameters. The control unit continuously monitors the cooking process and modifies parameters based on the initial load detection, creating a closed-loop system that compensates for the destabilizing effects of variable loading on temperature, air movement, and humidity

Inventive Principle:
Principle #23Feedback

AI summary

The invention relates to a method for carrying out a cooking process in a cooking space (3) of a cooking appliance (1), comprising the following method steps: simultaneously introducing a plurality of different cooking products (GP1-GP3) arranged on product trays (TR1-TR4) and having associated base cooking parameters (T1old-T3old) into the cooking space (3); determining at least one updated cooking parameter (T1new-T3new) of each cooking product (GP1, GP2 and GP3) introduced into the cooking space (3) as a function of the number of introduced product trays (TR1-TR4), the base cooking parameters (T1old-T3old), a pre-set optimisation value (TT) and/or an optimisation value (Topt) which can be determined individually for an optimised cooking process which is to be carried out; initiating the optimised cooking process simultaneously for all introduced cooking products (GP1-GP3); and removing the fully cooked cooking products (GP1-GP3) from the cooking space (3).
