Innovation Solution

A culinary preparation device with a temperature probe integrated into the counter-tool, allowing for precise temperature measurement and regulation of the mixing process, combined with a compound rotational movement of the working tool and counter-tool, optimizing the shape and movement to ensure uniform temperature and efficient mixing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a temperature sensor is placed in the tank to measure dough temperature, then temperature measurement capability is improved, but the mixing efficiency deteriorates because the sensor placement does not ensure uniform temperature distribution throughout the dough

Engineering Contradiction:
Improvetemperature measurementVSAvoidmixing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The temperature measurement function is segmented from the mixing function by placing the temperature sensor on the counter-tool rather than integrating it into the tank structure. This allows the mixing tools to operate independently without interference from temperature measurement components, thereby maintaining mixing efficiency while achieving accurate temperature monitoring at the dough-contacting surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The counter-tool serves as an intermediary carrier for the temperature sensor, positioning the measurement device at the interface between the mixing tools and the dough. This intermediary placement ensures that the sensor measures the actual dough temperature where mixing occurs, rather than measuring tank wall temperature, thereby improving measurement precision without compromising mixing performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the working tool shape is optimized for mixing, then mixing efficiency is improved, but temperature uniformity deteriorates because conventional shapes do not promote adequate heat distribution

Engineering Contradiction:
Improvemixing efficiencyVSAvoidtemperature uniformity
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The working tool is designed with non-uniform geometry where different sections have different functions: the upper portion is optimized for efficient mixing actions, while the lower portion near the dough contact point incorporates features that promote heat distribution and temperature uniformity. This local differentiation allows the tool to simultaneously achieve high mixing efficiency and maintain temperature homogeneity throughout the dough.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The working tool incorporates three-dimensional geometric features such as curved surfaces and varying cross-sections that create multiple flow paths for heat distribution. By adding dimensional complexity to the tool geometry, the design promotes thorough mixing and heat distribution throughout the dough volume, ensuring temperature uniformity while maintaining mixing efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Temperature

If a jacketed tank with cooling system is used to regulate temperature, then temperature control capability is improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvetemperature controlVSAvoiddevice complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The complex jacketed tank cooling system is extracted and replaced by a simpler temperature regulation approach using the counter-tool as the primary temperature measurement and control reference point. This extraction eliminates the need for complex thermal management infrastructure while maintaining effective temperature control through direct monitoring at the dough interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The counter-tool performs dual functions: it serves as both the mixing instrument and the temperature measurement reference point. By making the counter-tool self-sufficient for both mixing and temperature indication, the system eliminates the need for separate complex temperature control systems, thereby reducing device complexity while maintaining temperature regulation capability.

Inventive Principle:
Principle #25Self-service
