Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single temperature sensor is used in the probe, then the device structure is simple, but only one temperature point can be measured requiring an additional device for furnace temperature monitoring

Engineering Contradiction:

Improvetemperature measurement capabilityVSAvoidprobe structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines two temperature sensors (first temperature sensor for internal meat temperature, second temperature sensor for furnace temperature) into a single integrated probe body. This merging of multiple measurement functions into one device eliminates the need for separate monitoring devices and achieves multi-functional capability while maintaining probe integration.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The probe is designed with dual temperature sensing capability to perform multiple functions: monitoring both internal meat temperature and external furnace temperature simultaneously. This universal design allows a single probe to replace what would traditionally require multiple separate devices, enhancing adaptability without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If wired charging electrodes are used in the probe, then charging connection is established, but electrode contact becomes poor due to oil stains, oxidation and water scales during high temperature roasting

Engineering Contradiction:

Improvecharging reliabilityVSAvoidelectrode contamination

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical contact charging system (wired electrodes) with a wireless charging system. The wireless charging module uses electromagnetic field coupling to transfer energy without physical contact, thereby eliminating the harmful effects of oil stains, oxidation, and water scales that degrade electrode performance during high-temperature roasting operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless charging module acts as an intermediary between the power source and the probe battery, enabling energy transfer through electromagnetic fields rather than direct electrical contact. This intermediary mechanism avoids the contamination issues inherent in direct electrode contact while maintaining reliable charging functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)
