Solution Overview

Problem

Conventional logging tools face complications due to the need for power and communication cables, which can cause physical durability, cost, and insufficient bandwidth issues when using multiple sensors, particularly in environments requiring multiple sensors.

Innovation Solution

A modular control unit is coupled to a sensor unit, forming a sensor assembly that integrates with a system, enabling data processing, synchronization, and communication, and includes a housing, circuitry with a memory and processor, and a power source, allowing for wireless or wired communication, and adaptable power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional logging tools use power and communication cables to connect multiple sensors, then data collection is enabled, but physical durability, cost, and bandwidth sufficiency deteriorate

Engineering Contradiction:

Improvephysical durabilityVSAvoidcable dependency

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the logging tool into modular sensor units, each with its own power source and wireless communication capability. This segmentation eliminates the need for a single complex cable system connecting multiple sensors, thereby improving physical durability by removing vulnerable cable connections while maintaining the ability to collect data from multiple sensors independently.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If multiple sensors share a single cable for power and communication, then system cost is reduced, but bandwidth becomes insufficient

Engineering Contradiction:

Improvenumber of sensorsVSAvoidbandwidth sufficiency

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

Each sensor unit is equipped with its own power source and wireless communication module, making each unit self-sufficient and capable of independent operation. This multi-functionality approach allows multiple sensors to operate simultaneously without sharing a single cable, thereby providing sufficient bandwidth for each sensor while maintaining cost-effectiveness through standardized modular designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If conventional logging tools use cables for power and communication, then system simplicity is maintained, but adaptability to different sensor configurations deteriorates

Engineering Contradiction:

Improvesensor integration flexibilityVSAvoidsystem configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs dynamic modular sensor units that can be independently configured and deployed in various combinations. Each sensor unit can be adapted to different sensor types and configurations without requiring changes to the overall system architecture, thereby improving adaptability while managing complexity through standardized interfaces and protocols.

Inventive Principle:
