Solution Overview

Problem

The installation of power transmission lines is challenging due to the need for manual monitoring and feedback to control the orientation and tension of conductors during the pulling process, which can lead to damage and inefficiencies, especially in complex terrain where spotters may not be able to monitor the running board effectively.

Innovation Solution

An intelligent electrical conductor installation system that includes a puller sub-system, a tensioner sub-system, and an intelligent running board equipped with sensors and communication modules to collect and transmit data on the operational conditions of the conductor pull operation, allowing for real-time monitoring and control of the conductor installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual monitoring with spotters is used to control running board orientation and tension, then installation control is possible, but the system is labor-intensive and unreliable in complex terrain

Engineering Contradiction:
Improvemonitoring reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/manual monitoring system with an automated sensor-based system. Sensors mounted on the running board and blocks detect orientation (pitch, yaw, roll) and tension forces, eliminating the need for human spotters to visually monitor and report conditions during the pulling operation.

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

Solution Approach 2:

The system implements continuous feedback through sensors that monitor running board orientation and conductor tension in real-time. This feedback is processed to automatically adjust pulling and tensioning forces, enabling closed-loop control that improves reliability compared to manual monitoring where feedback is intermittent and subject to human error.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If spotters follow the running board to provide feedback, then orientation control is possible, but the system becomes inefficient and spotters may be unable to monitor in complex terrain

Engineering Contradiction:
Improveoperation easeVSAvoidinstallation efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The running board performs self-monitoring through integrated sensors that automatically detect its own orientation and the forces acting upon it. This self-service capability eliminates the need for external spotters to follow and report conditions, simplifying operation and improving efficiency simultaneously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent substitutes human spotters with automated sensing systems that continuously monitor running board orientation and tension conditions. This replacement eliminates the operational burden of deploying and coordinating spotters while improving monitoring capability in difficult terrain where human observers cannot effectively follow.

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

3Loss of information

If sensors and communication modules are added to the running board, then real-time monitoring capability is improved, but device complexity increases

Engineering Contradiction:
Improveinformation feedbackVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The sensor system on the running board serves multiple functions: detecting orientation (pitch, yaw, roll), measuring tension forces, and providing location data. This multi-functionality reduces the need for separate specialized devices, thereby limiting the increase in complexity while maximizing information feedback.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces communication modules as intermediaries that transmit sensor data to remote monitoring systems. These modules act as simple data relays rather than complex processing units, enabling real-time information feedback without significantly increasing the complexity of the running board itself.

Inventive Principle:
Principle #24Intermediary (Mediator)
