Solution Overview

Problem

Kitchen appliances, particularly food processors, lack convenience and efficiency in measuring and processing ingredients according to recipes, often requiring separate scales and measuring cups for accurate weight and volume measurements.

Innovation Solution

A multifunction kitchen appliance with integrated temperature control, weighing, and user interface capabilities that determines ingredient density and volume data, allowing users to input ingredient identifiers or read packaging codes for precise measurement, eliminating the need for separate scales and measuring cups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a kitchen appliance includes separate scales and measuring cups for accurate measurements, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveingredient measurement accuracyVSAvoidnumber of separate tools
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple measurement functions (weight measurement via weighing element and volume measurement via density calculation) into a single integrated kitchen appliance. The control unit integrates both weight data from the weighing element and volume data calculated from density information, eliminating the need for separate scales and measuring cups while maintaining measurement accuracy.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The kitchen appliance is designed with multi-functionality, serving both as a food processor and as an integrated measurement system. The appliance can process ingredients while simultaneously measuring their weight and calculating volume, making it a universal tool that replaces multiple separate kitchen tools.

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

2Ease of operation

If a kitchen appliance integrates weighing and volume measurement functions, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveconvenience of recipe implementationVSAvoidintegrated measurement system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control unit automatically performs density determination and volume calculation based on weight data from the weighing element. The system determines density information either from user input via the user interface or from stored data, and automatically calculates volume data without requiring manual intervention for complex computations, making the appliance self-sufficient.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit acts as an intermediary that bridges weight measurement and volume measurement. It receives weight data from the weighing element, determines density information (either from user input or stored data), and calculates volume data, thereby mediating between different measurement types and presenting unified measurement information to the user.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If the kitchen appliance determines density information for ingredient conversion, then measurement precision is improved, but loss of time occurs during density determination

Engineering Contradiction:
Improvevolume measurement accuracyVSAvoidtime for density determination
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The appliance stores density information for various ingredients in advance. When an ingredient is used, the control unit can quickly retrieve the pre-stored density information from memory, eliminating the need to determine density in real-time and thus reducing the time required for volume calculations while maintaining measurement precision.

Inventive Principle:
Principle #10Preliminary action
