Solution Overview

Problem

Existing dual pipe rod assembly sections for horizontal drilling face challenges in maintaining the service life of probes and cables due to mechanical stress and limited runtime of accumulators, with cable damage being a significant concern.

Innovation Solution

A dual pipe rod assembly section design where the probe is rotatingly coupled to the outer rod section, protected within the inner rod section, and connected via a cable guided inside the assembly, utilizing magnetic coupling for rotation and a nonmagnetic tube-shaped section for accurate measurement, reducing mechanical stress and enhancing service life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the probe is connected via a cable guided between inner and outer rod assemblies, then the probe can be supplied with voltage, but the cable is subjected to strong mechanical stress and can be damaged

Engineering Contradiction:

Improvecable durabilityVSAvoidmechanical stress on cable

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical cable connection with a wireless communication system. The probe determines position and direction data wirelessly and transmits this information to the surface without any physical cable connection, thereby eliminating mechanical stress on cables entirely.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the cable from the system by implementing wireless communication. The probe operates independently without requiring a physical cable for power or data transmission, eliminating the source of mechanical stress.

Inventive Principle:
