Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional methods are used to deploy shape memory materials, then the elements can be deployed for fluid filtration and wellbore support, but the volume determination of activation fluids becomes complex and time-consuming

Engineering Contradiction:
Improvedeployment efficiencyVSAvoidengineering and preparation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent extracts the activation fluid delivery system from the bulk fluid and isolates it into a separate capillary line. This allows precise control of activation fluid volume independent of the bulk fluid volume, eliminating the need for complex volume calculations and significantly reducing engineering and preparation time while maintaining deployment efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The capillary line utilizes porous material properties to enable controlled fluid transport through capillary action. This passive delivery mechanism eliminates the need for active pumping and complex volume determination, as the porous structure naturally regulates the activation fluid flow to the shape memory element, reducing both engineering complexity and preparation time.

Inventive Principle:
Principle #31Porous materials

2Productivity

If conventional activation fluid delivery is used, then shape memory elements can be activated, but fluid dilution occurs leading to excess fluid use and longer well downtime

Engineering Contradiction:
Improveoperational efficiencyVSAvoidactivation fluid volume
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The activation fluid is extracted from the bulk fluid stream and delivered through a dedicated capillary line directly to the shape memory element. This prevents mixing and dilution with bulk fluid, ensuring that the precise amount of activation fluid needed is delivered without excess, thereby reducing loss of substance and improving operational efficiency by minimizing well downtime.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The capillary line acts as an intermediary between the activation fluid source and the shape memory element. This intermediary structure provides a controlled, isolated pathway that prevents fluid dilution and ensures direct application of the activation fluid to the element, eliminating excess fluid use and reducing well downtime.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If activation fluid is applied without precise delivery mechanism, then the shape memory element can be activated, but excess engineering time is required for fluid preparation

Engineering Contradiction:
Improvefluid application simplicityVSAvoidengineering time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The capillary line enables self-service fluid delivery through capillary action, where the porous material automatically draws and transports the activation fluid to the shape memory element without requiring external pumping or complex control systems. This passive, self-regulating mechanism simplifies operation and reduces engineering time by eliminating the need for precise manual fluid preparation and delivery system management.

Inventive Principle:
Principle #25Self-service
