Solution Overview

Problem

Existing cooking management devices lack visual indication of the type of cooking receptacle they are configured for, leading to improper signal adaptation during cooking, which can result in suboptimal cooking outcomes.

Innovation Solution

A cooking management device with a segmented liquid crystal display that activates specific pictograms representing the type of cooking vessel and cooking program, allowing users to verify proper configuration and ensuring signal adaptation to the receptacle type, featuring a microcontroller with limited inputs/outputs for economical implementation and automatic recognition of cooking vessels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a segmented liquid crystal display is used to show pictograms representing cooking vessel types and programs, then the user can verify proper configuration and ensure signal adaptation, but the device complexity increases compared to a simple display

Engineering Contradiction:
Improveconfiguration accuracyVSAvoiddisplay complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The display is segmented into multiple independent segments that can be individually activated to form different pictograms. Each segment represents a specific cooking vessel type or program state, allowing the system to convey multiple pieces of information using a limited number of discrete display elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a complex matrix display or multiple separate indicators, the patent uses a simplified segmented display that copies or represents the essential information (vessel type and program status) through pictographic symbols. This reduces the physical complexity while maintaining the reliability of information display.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If the control device activates multiple segments to display different pictograms for various cooking vessel types and programs, then the adaptability to different cooking configurations is improved, but the number of required display segments and control inputs/outputs increases

Engineering Contradiction:
Improvecooking program adaptabilityVSAvoiddisplay segment quantity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The segmented display is designed to serve multiple functions by displaying different pictograms for various cooking vessel types (frying pan, saucepan, casserole, pressure cooker) and different program states using the same physical segments. This universal display approach allows one display structure to adapt to numerous cooking configurations without requiring separate indicators for each case.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display segments are dynamically activated and deactivated based on the detected cooking vessel type and selected program. The control device adjusts which segments are illuminated in real-time, allowing the same physical display to convey different information states without requiring additional hardware for each configuration.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a microcontroller with limited inputs/outputs is used to control the segmented display, then the implementation cost is reduced, but the capability to display complex information is constrained

Engineering Contradiction:
Improveimplementation costVSAvoiddisplay information capability
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The information to be displayed is segmented into discrete pictographic elements that can be represented by a limited number of display segments. By dividing the information into essential components (vessel type identification and program status), the system can convey meaningful information using fewer control outputs while maintaining manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses a simplified microcontroller that copies or represents the essential cooking parameters through pictographic symbols rather than displaying detailed numerical data or text. This information copying approach reduces the computational and I/O requirements while preserving the core functional information needed by the user.

Inventive Principle:
Principle #26Copying
