Expandable CIPP Lining Trailer for Rapid On-Site Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional CIPP lining installation process is hindered by the need for time-consuming setup and teardown of equipment due to the wide dimensions of pinch presses and conveyors, which are too large for conventional trucks or trailers, requiring on-site assembly and disassembly, and the lack of efficient connectivity for electrical and fluid components.
Innovation Solution
A trailer with an expandable bed, cover, and staging apparatus that includes a conveyance system and pinch press, allowing for rapid conversion between collapsed and expanded configurations for transportation and on-site use, with integrated electrical and fluid connections for seamless setup and teardown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional trucks or trailers are used to transport CIPP equipment, then transportation is simplified, but the equipment cannot be permanently installed due to width constraints
Solution Approach 1:
The trailer bed is designed with expandable side walls and floor that can transition between a collapsed configuration for transportation and an expanded configuration for installation. This dynamic structure allows the same platform to accommodate both transport constraints and installation requirements without requiring separate equipment sets.
Solution Approach 2:
The trailer is divided into modular components including the chassis, expandable floor sections, and detachable staging apparatus. This segmentation allows the equipment to be configured for different purposes - compact for transport and expanded for installation - while maintaining ease of operation in both states.
2Adaptability or versatility
If pinch presses and conveyors are configured to handle large diameter pipes, then they can process larger pipes, but they become too wide to be permanently installed on conventional trucks or trailers
Solution Approach 1:
The pinch press and conveyor systems are designed to be collapsible or reconfigurable. During transportation, these components are folded or compressed to fit within standard trailer dimensions. At the installation site, they are expanded or deployed to achieve the necessary width for handling large diameter pipes up to 96 inches.
Solution Approach 2:
The staging apparatus components are designed to nest within each other or fold into compact configurations that fit within the trailer bed during transport. When deployed at the installation site, they unfold or expand to provide the full working width required for large pipe operations.
3Manufacturing precision
If equipment is unloaded and reassembled on-site, then it can be properly configured for installation, but the setup process becomes time-consuming
Solution Approach 1:
The trailer is pre-configured with mounting structures, electrical connections, and fluid pathways during manufacturing. This preliminary preparation eliminates the need for complex on-site assembly - operators simply need to deploy the pre-positioned components and connect pre-routed utilities, reducing setup time while maintaining configuration accuracy.
Solution Approach 2:
Multiple functions are integrated into unified components - the trailer bed serves as both transport platform and installation base, electrical connections are pre-terminated and ready for plugging, and fluid lines are pre-routed and connected. This merging of functions reduces the number of separate assembly steps required on-site.
4Object-affected harmful factors
If a temporary shelter is constructed over the equipment, then equipment is protected from environmental elements, but the construction process adds significant time and labor
Solution Approach 1:
The trailer's cover or tarp system is integrated with the equipment staging area, providing protection as part of the standard trailer structure rather than as a separate construction project. The cover is pre-attached to the trailer frame and automatically provides protection when the trailer is positioned at the installation site.
Solution Approach 2:
The protective cover is pre-installed and secured to the trailer during manufacturing. This preliminary action ensures that protection from environmental elements is immediately available upon arrival at the site, eliminating the need for on-site shelter construction while maintaining adequate protection throughout the installation process.
5Ease of operation
If electrical and fluid connections are made on-site, then equipment can be powered and operated, but the connection process becomes complex and time-consuming
Solution Approach 1:
All electrical connections are pre-terminated with connectors ready for plugging, and fluid lines are pre-routed with quick-connect fittings. This preliminary preparation transforms complex wire-by-wire connections into simple plug-and-play operations, maintaining equipment operability while dramatically reducing connection complexity and time.
Solution Approach 2:
The trailer is designed with universal connection points and standardized interfaces for both electrical and fluid connections. These multi-functional connection points can accommodate different equipment configurations while maintaining a consistent, simple connection process regardless of the specific equipment being installed.

AI summary
A trailer for staging a pipe lining for in-place installation and curing of the pipe lining has an expandable cover including a roof and side walls. Pipe lining staging apparatus located within the cover can be converted between a collapsed configuration and an expanded configuration. The floor can expand outward from the chassis for holding the staging apparatus in an expanded condition.
