Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If temperature sensors are permanently installed in the cooking vessel, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improvetemperature measurement accuracyVSAvoidsensor installation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor system is divided into separate components: a removable sensor element that can be detached from the cooking vessel. This segmentation allows the sensor to be easily installed and removed without permanently modifying the vessel structure, reducing device complexity while maintaining measurement capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor element is designed as a simple, replaceable component rather than a permanent installation. This approach reduces the complexity of the overall system and allows for easy replacement or upgrading of sensors without replacing the entire cooking vessel or control system

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Measurement precision

If sensors are arranged to measure bottom temperature, then measurement precision is improved, but ease of operation deteriorates due to cleaning difficulties

Engineering Contradiction:
Improvebottom temperature measurement accuracyVSAvoidcooking vessel cleaning ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

By separating the sensor element from the cooking vessel body, the sensor can be easily removed before cleaning. This eliminates the problem of sensors being trapped in hard-to-reach areas, making the cooking vessel easy to clean while maintaining accurate bottom temperature measurement capability when the sensor is installed

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If multiple sensors are used for different positions, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature distribution measurement accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor element is designed with universal applicability to measure temperature at different positions (bottom, wall, or other locations) depending on where it is placed. This multi-functional design allows a single sensor type to serve multiple measurement purposes, reducing the need for multiple specialized sensors and thereby reducing device complexity

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