Solution Overview

Problem

Inaccessible electronic and hydraulic devices in subsurface locations, such as boreholes, pose challenges in isolating them from larger systems to prevent system failures, as existing methods are either costly or impractical for intervention.

Innovation Solution

An apparatus that includes a node terminator with a communication linkage and control members to terminate signal communication by destroying a consumable element of the linkage upon receiving a controlled signal, using electrical energy to isolate nodes from the carrier, allowing for operational isolation without requiring power adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If communication with subsurface nodes is terminated by physical retrieval or intervention, then system isolation is achieved, but operational complexity and cost increase significantly

Engineering Contradiction:
Improvesystem reliabilityVSAvoidisolation operation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The node terminator enables nodes to perform self-isolation by automatically destroying their communication linkage when receiving a controlled signal, eliminating the need for external intervention or physical retrieval operations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces mechanical intervention methods (physical retrieval, manual isolation) with an electrical/electronic system that uses controlled signals and consumable elements to achieve communication termination

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If communication linkage is destroyed to isolate nodes, then system failure prevention is improved, but energy consumption increases

Engineering Contradiction:
Improvesystem failure preventionVSAvoidenergy consumption for termination
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The invention extracts only the necessary energy amount required to destroy the consumable element and break the communication linkage, rather than requiring continuous or excessive energy input for sustained isolation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The controlled signal changes the energy state of the consumable element by delivering a specific energy threshold that transforms the element from functional to non-functional state, achieving isolation through parameter transformation

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If nodes remain connected to carrier, then operational simplicity is maintained, but system vulnerability to failures increases

Engineering Contradiction:
Improveoperational simplicityVSAvoidsystem vulnerability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The node terminator is pre-configured with the capability to destroy the communication linkage upon receiving a controlled signal, allowing isolation to be executed as a preliminary protective measure before system failures can propagate

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention segments the communication system into independent node units with individual terminators, allowing selective isolation of specific nodes without affecting the entire system, thus maintaining operational simplicity while reducing vulnerability

Inventive Principle:
Principle #1Segmentation
