Pipeline Inspection Hub Coupling for Controlled Cable Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pipeline inspection devices face challenges in efficiently locating obstructions and defects within underground pipes, particularly in accessing and visualizing the interior of pipes from a distance and managing the cable deployment effectively.
Innovation Solution
A pipeline inspection device featuring a rotatable drum housing a cable with a camera and electrical components, including a hub for power and wireless communication, and a stand with a mounting assembly that allows for secure coupling and controlled rotation, along with a brake assembly to manage rotational speed, enabling effective cable deployment and visualization of pipe interiors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the cable is extended into the pipe to reach distant obstructions, then the inspection coverage is improved, but the cable management and deployment control become more difficult
Solution Approach 1:
The drum is made rotatable to dynamically adjust cable deployment. The brake assembly provides dynamic control over the drum's rotational speed, enabling precise cable feeding and retrieval operations while maintaining ease of operation despite extended cable lengths.
Solution Approach 2:
The brake assembly with actuator provides controlled feedback mechanisms to regulate cable deployment. By adjusting the brake engagement, the system feedback-controls the rotational speed of the drum, ensuring precise cable management during extension and retrieval.
2Productivity
If the drum rotational speed is increased to improve inspection speed, then the productivity is improved, but the cable deployment control and safety are worsened
Solution Approach 1:
The brake assembly provides dynamic speed control of the drum rotation. The actuator can adjust the brake engagement level to optimize rotational speed for different operational phases, maintaining both high productivity and safe cable deployment control.
Solution Approach 2:
The system changes the rotational speed parameter of the drum based on operational requirements. The brake assembly enables continuous adjustment of this parameter, allowing fast inspection when needed while maintaining control safety through regulated deceleration and stopping.
3Stability of the object's composition
If the hub is permanently fixed to the stand, then the structural stability is improved, but the ease of repair and component replacement are worsened
Solution Approach 1:
The mounting assembly is segmented into separate coupling elements: engagement members on the hub and corresponding members on the stand. This segmentation allows the hub to be easily detached and replaced while maintaining stable operation during use, balancing structural stability with repairability.
