Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single temperature probe is used for all food items and cooking methods, then device simplicity is maintained, but measurement precision and adaptability deteriorate due to inability to selectively measure different temperatures

Engineering Contradiction:
Improvetemperature measurement precisionVSAvoidprobe structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The temperature probe is divided into multiple independent insertion sections (first insertion section, second insertion section, etc.), each equipped with its own temperature sensor. This segmentation allows each section to be optimized for specific temperature ranges or food types while maintaining overall device functionality for diverse measurement applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The probe is designed with multiple insertion sections that can be selectively used for different food items and cooking methods, making a single probe capable of performing multiple measurement functions. The data transmission device enables wireless communication for all sections, providing universal applicability across various cooking scenarios without requiring separate specialized probes.

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

2Adaptability or versatility

If multiple temperature probes are provided for different food items and cooking methods, then adaptability and measurement precision improve, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improveprobe adaptabilityVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple temperature sensing sections are merged into a single integrated probe device with a common data transmission device. This consolidation allows users to operate one probe instead of multiple separate devices, maintaining ease of operation while achieving the adaptability of having multiple specialized probes for different food items and cooking methods.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The unified probe design with multiple insertion sections provides universal functionality, allowing a single device to handle various cooking scenarios. The wireless data transmission capability is shared across all sections, enabling users to easily monitor temperatures from different sections without requiring multiple separate probes or complex switching mechanisms.

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

3Ease of operation

If wireless data transmission is implemented, then ease of operation and real-time monitoring improve, but energy consumption increases

Engineering Contradiction:
Improvedata transmission convenienceVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The wireless data transmission device operates periodically rather than continuously, transmitting temperature data at intervals when measurements are complete or when changes are detected. This periodic operation maintains ease of real-time monitoring while significantly reducing energy consumption compared to continuous transmission, allowing the probe to function effectively during extended cooking periods.

Inventive Principle:
Principle #19Periodic action
