Adjustable CIPP Liner Feed Roller for Folding Through Small Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for feeding CIPP liners, including UV cured CIPP liners, into access openings lack configurability and are inefficient in folding the liners during the feeding process, making it difficult to maneuver them through smaller openings due to their bulkiness and weight.
Innovation Solution
A CIPP liner feed roller system comprising a main roller and a clamping roller with adjustable distance, driven by a motor and controlled by a controller, which includes accessories like a folding roller assembly and guide rollers to facilitate the pulling and folding of CIPP liners for easier insertion through access openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If UV cured CIPP liners are used, then environmental friendliness is improved, but weight and bulkiness increase making them difficult to maneuver
Solution Approach 1:
The CIPP liner is divided into multiple sections or segments that can be folded and connected. The folding mechanism allows the liner to be segmented into manageable portions that can be easily maneuvered through access openings while maintaining the environmental benefits of UV cured material
Solution Approach 2:
The liner is designed with folding capabilities that transform it from a flat two-dimensional structure to a three-dimensional folded configuration. This dimensional transformation allows the bulky liner to be compressed into a compact form that can be easily inserted through small openings
2Ease of operation
If conventional CIPP liners are used, then ease of handling is improved, but environmental harm increases due to thermosetting resin leaching
Solution Approach 1:
The patent replaces the traditional thermosetting resin impregnation method with a UV cured polymer system. This substitution eliminates the harmful leaching issue while the folding mechanism provides the mechanical ease of handling previously associated with conventional liners
3Adaptability or versatility
If manual folding of CIPP liner is performed, then configurability is improved, but productivity decreases due to labor intensity
Solution Approach 1:
The folding roller assembly is designed to automatically fold the CIPP liner as it is fed through the system. This self-service folding mechanism eliminates the need for manual labor while maintaining the configurability to adapt to different liner sizes and access opening dimensions
4Device complexity
If fixed-distance rollers are used, then device complexity is reduced, but adaptability decreases for different liner thicknesses
Solution Approach 1:
The roller system incorporates adjustable-distance positioning that allows the rollers to dynamically adapt to different liner thicknesses. This dynamic adjustment capability provides versatility for handling various liner specifications while maintaining relatively simple device architecture through straightforward mechanical adjustment mechanisms

AI summary
A CIPP liner feed roller for manipulating and feeding CIPP liner by pulling CIPP liner from a liner source and feeding it to where it is needed. The CIPP liner feed roller generally includes a main roller attached to a frame, a clamping roller attached to the frame and configured to be in parallel with the main roller, wherein the distance between the clamping roller and the main roller can be adjusted using one or more actuators, a drive unit comprising a motor configured to control the rotation of the main roller within the frame, a controller coupled to the drive unit and the one or more actuators, wherein the controller is configured to control the rotation of the main roller and the distance between the clamping roller and the main roller, and a support beam attached the frame and configured to be in parallel with the main roller.
