CIPP Liner Reel Assembly for Controlled Winding and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CIPP liner systems face challenges in efficiently dispensing and handling UV cured-in-place pipe liners due to their bulkiness and fragility, making it difficult to manage and deploy them, especially in large pipe sizes, leading to issues with transportation and installation.
Innovation Solution
A CIPP liner reel system comprising a frame connected to a reel and drive unit, with a core that allows for winding and unwinding of the liner using a strap, and a tractor connector for easy transportation, enabling controlled dispensing and deployment of the liner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If UV cured CIPP liners are used for large pipe sizes, then the liner can be deployed in large conduits, but the liner becomes bulky and heavy making it difficult to handle and transport
Solution Approach 1:
The CIPP liner is divided into multiple manageable sections or segments that can be individually handled and transported. The liner is fed from a spool in a controlled manner, allowing it to be deployed section by section rather than moving the entire liner at once, making it feasible to work with large diameter liners.
Solution Approach 2:
A water bag or air cushion system is introduced as an intermediary medium between the liner and the surrounding environment. This intermediary allows the bulky liner to be suspended and positioned without direct handling, reducing the physical manipulation required and making it easier to work with large, heavy liners.
2Reliability
If UV cured CIPP liners are exposed to sunlight, then the liner can be cured, but the outer protective layer damages and the liner hardens within minutes
Solution Approach 1:
The liner is prepared and positioned in advance with protective coverings in place before deployment. The outer protective layer is intact during transport and installation, preventing premature exposure to sunlight. Curing is initiated only after the liner is properly positioned, ensuring the protective layer remains undamaged until the curing process begins.
Solution Approach 2:
The installation process is expedited to minimize the time the liner is vulnerable to damage. The liner is quickly positioned and the protective layer is either removed controlledly or UV curing is immediately initiated once positioning is complete, reducing the window of vulnerability to sunlight exposure before the liner hardens.
3Productivity
If excess CIPP liner is pulled through the host pipe, then the liner can be installed, but the excess liner must be returned or discarded creating waste
Solution Approach 1:
The reel system automatically feeds the liner at the required rate as it is pulled through the host pipe. The system self-regulates the liner dispensing based on the pull rate, ensuring that liner is supplied precisely when needed without creating excess that would need to be returned or discarded. This eliminates material waste while maintaining installation speed.

AI summary
A CIPP liner reel system for managing the utilization and deployment of CIPP liners. The CIPP liner reel system generally includes a frame connected to a reel and drive unit. The drive unit is connected to the reel to control the rotation of its core. This core contains an opening that provides access to a connector unit within the core. This connector unit can be used to connect the reel to the end of a CIPP liner using a strap. Rotation of the core causes CIPP liner to wind on to or unwind from the reel. The reel may also contain a left guide member and a right guide member to assist in controlling the process of winding and unwinding the CIPP liner. The frame may also include a tractor connector that enables the CIPP liner reel system to be coupled to and transported by a tractor without affecting its operation.
