Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional Baumkuchen baking machines are difficult for small-scale confectioneries to implement and operate, as they require skilled personnel to ensure proper doneness, which is a challenge due to limited resources and lack of familiarity with the cake in markets like Germany.

Innovation Solution

A Baumkuchen baking system that includes a communication unit, a baking machine with an oven, a roller, a camera, and a control unit, which uses a learning-enhanced model to determine doneness based on images of the batter's outer peripheral surface, allowing for automatic control and remote operation without a skilled chef.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional Baumkuchen baking machine is used, then multiple Baumkuchen can be baked simultaneously, but the machine becomes too complex and requires skilled pastry chefs to operate

Engineering Contradiction:

Improvebatch baking capacityVSAvoidmachine complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual observation and decision-making by pastry chefs with an automated image recognition system. A camera captures images of the Baumkuchen surface, and an image processing unit automatically determines doneness based on color analysis, eliminating the need for skilled operators while maintaining batch baking capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The Baumkuchen baking machine performs self-monitoring and self-control through the integrated camera and image processing system. The machine automatically adjusts baking parameters based on real-time surface color analysis, enabling it to operate autonomously without requiring skilled pastry chefs

Inventive Principle:

Principle #25Self-service

2Reliability

If a conventional Baumkuchen baking machine is used, then baking can be performed, but skilled personnel are required to ensure proper doneness

Engineering Contradiction:

Improvebaking quality consistencyVSAvoidoperation skill requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a closed-loop feedback system where the camera continuously monitors the Baumkuchen surface color during baking, and the image processing unit compares real-time color data against target doneness criteria. This automatic feedback mechanism ensures consistent quality without requiring skilled operators to visually assess doneness

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent substitutes the human visual assessment and decision-making process with an automated image recognition system that objectively measures surface color characteristics, eliminating the need for skilled pastry chefs while maintaining reliable quality control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If manual operation by skilled chefs is used, then proper doneness can be achieved, but the number of available chefs is limited

Engineering Contradiction:

Improvedoneness control precisionVSAvoidoperator availability

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent replaces the specialized knowledge and skills of pastry chefs with an automated image recognition system that can be deployed in any location. The system captures images, processes color data, and determines doneness automatically, making high-precision doneness control accessible without requiring scarce skilled operators

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If automatic control using image recognition is implemented, then skilled personnel are not needed, but a camera and control unit must be added

Engineering Contradiction:

Improveoperation skill requirementVSAvoidsystem component count

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the camera and image processing functions into the existing Baumkuchen baking machine control system. The image processing unit leverages the existing control unit's processing capabilities, and the camera is positioned to utilize the oven's viewing window, minimizing additional hardware while achieving automated doneness determination

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A Baumkuchen baking system 10 includes: a Baumkuchen baking machine 1 including an oven 2, a batter container 4, a roller 3 and a camera 7; and a control unit 8. A server 20 is capable of accessing a storage unit 30 that stores a learning-enhanced model obtained by learning a doneness determination or baking control based on an image of the outer peripheral surface of Baumkuchen batter. The control unit 8 includes: a user interface unit 83; and an automatic control unit 82 that determines doneness or baking control using the learning-enhanced model provided by the server 20 based on an image, captured by the camera 7, of the outer peripheral surface of Baumkuchen batter currently being baked and uses the result of determination to automatically control baking of each layer of the Baumkuchen batter.
