Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If thermal insulation material is used to reduce heat loss, then energy efficiency is improved, but the outside surface temperature may still exceed safety thresholds in explosive environments

Engineering Contradiction:

Improveheat lossVSAvoidexplosion risk

Core Design Contradiction:

Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The insulation system is segmented into two functional parts: thermal insulation material for heat reduction and an active cooling system with cooling channels for temperature control. This segmentation allows each component to address its specific function independently, resolving the contradiction between energy efficiency and safety.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A cooling fluid acts as an intermediary substance that transfers heat from the reactor to the external environment through cooling channels in the insulation layer. This intermediary mechanism enables active temperature control while maintaining the thermal insulation function, simultaneously addressing energy efficiency and safety requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If insulation material is added to reduce heat loss, then energy efficiency is improved, but device complexity and cost increase

Engineering Contradiction:

Improveprocess heat lossVSAvoidinsulation structure

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The thermal insulation function and active cooling function are merged into a single integrated insulation structure. The cooling channels are incorporated within the insulation material itself, combining two functions into one component system. This reduces overall device complexity compared to having separate insulation and cooling systems, while maintaining energy efficiency.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The insulation structure serves multiple functions simultaneously: thermal insulation to reduce heat loss and active cooling to control surface temperature. This multi-functionality eliminates the need for separate systems, reducing device complexity and cost while achieving energy efficiency goals.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If more insulation material is used to control outside surface temperature, then safety is improved, but energy efficiency deteriorates due to increased heat loss

Engineering Contradiction:

Improvesurface temperature controlVSAvoidprocess heat loss

Core Design Contradiction:

Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The cooling fluid circulates through the insulation material proactively to prevent excessive heat accumulation before it reaches the outer surface. This preliminary cooling action maintains surface temperature below safety thresholds while minimizing the amount of insulation material needed, thereby reducing heat loss and improving energy efficiency.

Inventive Principle:

Principle #10Preliminary action
