Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a heating block directly contacts the container to heat it, then heating efficiency is improved, but the container may crack or deform due to high temperature

Engineering Contradiction:

Improveheating efficiencyVSAvoidcontainer cracking or deformation

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

A heat insulating block is introduced as an intermediary between the heating block and the container. The heat insulating block surrounds the container and transfers heat uniformly without direct contact between the heating block and container, preventing thermal shock and deformation while maintaining heating efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Temperature

If a heating block is used to heat the container, then heating function is achieved, but uniform heating of the container is difficult

Engineering Contradiction:

Improveheating functionVSAvoiduniform heating

Core Design Contradiction:

TemperatureVSManufacturing precision

Solution Approach 1:

The heat insulating block is designed with specific thermal properties and geometry to distribute heat uniformly across the container surface. By controlling the thermal conductivity and shape of the heat insulating block, uniform temperature distribution is achieved while maintaining the heating function.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If an indicator such as LED is used to display heating block operation, then operational status is visible, but temperature measurement during qualification evaluation is not possible

Engineering Contradiction:

Improveoperational status displayVSAvoidtemperature measurement during qualification evaluation

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

A temperature sensor is introduced as an intermediary measurement device. The temperature sensor can be inserted into a hole in the heat insulating block to measure the heating block temperature during qualification evaluation, while the LED indicator continues to display operational status.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If the heating block operates at high temperature, then thawing efficiency is improved, but energy consumption increases

Engineering Contradiction:

Improvethawing efficiencyVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The heat insulating block maintains thermal energy continuously by surrounding the container during the thawing process. This continuous heat retention reduces energy loss and allows the heating block to operate at optimal temperatures for thawing efficiency without excessive energy consumption.

Inventive Principle:

Principle #20Continuity of useful action
