Duct Mapping With 6-DoF Tracking for Cable Installation Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mapping ducts are inefficient and time-consuming, particularly when installing cables, as they rely on guesswork and can lead to cable sticking or inefficient installation due to unknown duct path complexities.
Innovation Solution
A tracking unit with 6-degree of freedom microprocessor and sensors is passed through the duct to collect position data, which is then used to map the duct and provide recommendations for cable installation, including flow rate and pressure settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional guesswork methods are used for cable installation planning, then installation process is simple, but installation efficiency is low and time-consuming
Solution Approach 1:
The patent applies preliminary action by mapping the duct path before cable installation. A tracking unit is passed through the duct to collect position data, which is processed to create a digital map showing bends, curves, and path complexity. This preliminary mapping information is then used to plan the cable installation strategy, determining optimal blowing locations and parameters in advance, thereby improving installation efficiency without excessive complexity.
2Measurement precision
If duct mapping is performed accurately, then cable installation efficiency improves, but measurement and detection difficulty increases
Solution Approach 1:
The patent uses an intermediary approach by employing a separate tracking unit with sensors to detect duct characteristics before cable installation. The tracking unit contains position sensors, accelerometers, and gyroscopes that measure duct path parameters. This intermediary measurement system provides accurate duct mapping data without requiring the cable installation equipment itself to perform complex detection, thereby achieving high measurement precision while managing detection complexity.
3Reliability
If cable installation is attempted without duct mapping, then equipment and process remain simple, but cable may become stuck requiring reinstallation
Solution Approach 1:
The patent applies preliminary action by performing duct mapping and installation planning before attempting cable installation. The system analyzes the mapped duct path to identify challenging sections such as sharp bends or multiple curves, and pre-determines optimal cable blowing locations and parameters. This preliminary preparation significantly increases the likelihood of successful cable installation in a single attempt, reducing the need for time-consuming reinstallation due to cable sticking.
