Removable Hub Coupling Inside Cable Drums for Pipe Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pipeline inspection devices face challenges in efficiently locating and documenting obstructions and damage within underground pipes, particularly in accessing distant areas of sewer pipelines without effective visualization and communication tools.
Innovation Solution
A pipeline inspection device featuring a rotatable drum housing a cable with a camera and electrical components, including a wireless communication module, a dedicated monitor, and a smart device for real-time image display, allowing for remote visualization and documentation of pipe interiors and obstructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a cable with camera is pushed down a pipe for inspection, then the ability to locate obstructions is improved, but the ability to visualize and document findings in real-time deteriorates
Solution Approach 1:
A wireless communication module acts as an intermediary between the camera/sonde at the cable end and external devices. This module transmits captured images and location data wirelessly through the pipe environment, enabling real-time visualization without requiring physical connection back to the surface, thus resolving the information loss problem while maintaining location accuracy.
2Adaptability or versatility
If electrical components are housed in a hub for the pipeline inspection device, then the functionality and documentation capability are improved, but the device complexity and structural integration deteriorate
Solution Approach 1:
The hub containing electrical components is designed as a separate, modular unit that can be independently manufactured and tested. It features standardized mounting interfaces (first and second engagement members) that simplify integration with the drum assembly, reducing overall system complexity while maintaining full electrical functionality for camera operation and data transmission.
Solution Approach 2:
The hub is designed with universal mounting capabilities through multiple engagement members that can interface with different drum configurations. This multi-functional design allows the same hub unit to be adapted to various pipeline inspection cable systems without requiring custom integration for each application, thereby improving versatility while maintaining structural simplicity.

AI summary
A pipeline inspection device, including a rotatable drum housing a cable, where the cable is extendable into a pipe, a camera positioned on an end of the cable, and a hub housing electrical components of the pipeline inspection device and including a battery housing. A stand includes a mounting assembly having a first portion rotatably supporting the drum and a second portion supporting the hub within an interior of the drum, the second portion including a core, where the hub is removably coupled to the mounting assembly via the core. The hub is removably coupled to the mounting assembly by a first engagement member on the hub and a second engagement member on the core.
