Solution Overview

Problem

Existing household appliance systems lack the ability to adjust stirring operations based on the viscosity of the medium, leading to suboptimal cooking results and user dissatisfaction.

Innovation Solution

Incorporating a viscosity detection unit that monitors the viscosity parameter of the medium using the stirring unit, allowing for adaptive control of the stirring process, thereby optimizing recipe execution and user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a stirring unit operates according to a fixed program sequence independently of medium viscosity, then the control system remains simple and reliable, but the cooking results become suboptimal and user satisfaction decreases

Engineering Contradiction:
Improvecooking result qualityVSAvoidcontrol system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where a viscosity detection unit continuously monitors the viscosity parameter of the medium and provides this information to the control unit. The control unit then adjusts the stirring unit's operating parameters (speed, direction, intensity) based on the detected viscosity, creating a closed-loop control system that adapts to changing medium properties during cooking

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables the cooking process to self-regulate by using the viscosity detection unit to automatically sense medium properties and trigger appropriate stirring adjustments without user intervention. The control unit autonomously interprets viscosity data and modifies stirring parameters to achieve optimal cooking results

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a viscosity detection unit is added to monitor medium viscosity, then cooking results are optimized and user satisfaction increases, but the device complexity and cost increase

Engineering Contradiction:
Improveuser convenienceVSAvoidsystem structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The viscosity detection unit serves multiple functions: it detects medium viscosity, provides feedback to the control unit, enables automatic stirring parameter adjustment, and can potentially monitor cooking progress. This multi-functionality justifies the added complexity by delivering comprehensive benefits across multiple operational aspects

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

Solution Approach 2:

The patent replaces manual user judgment and adjustment of stirring parameters with an automated sensor-based system. The viscosity detection unit uses non-contact or minimal-contact sensing methods to detect medium properties, substituting mechanical probing with electronic detection that integrates seamlessly into the existing control architecture

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
