Pipe Liner Insertion Drum With Swappable Positioning Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods require multiple devices to insert and position pipe linings into pipes, which is inefficient and cumbersome, especially for pipes already laid in the ground.
Innovation Solution
A device with a drum-shaped housing and interchangeable attachments allows for both the insertion and final positioning of pipe linings using a single device, featuring a retractor, attachment elements, and compressed air connections to facilitate the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are used to insert and position pipe linings, then the insertion and positioning functions can be performed, but the equipment complexity and operational efficiency deteriorate
Solution Approach 1:
The patent combines the insertion device and positioning device into a single integrated device. The housing contains both the winding device for inserting the pipe lining and the calibration hose for positioning it. This merging eliminates the need for multiple separate devices while maintaining both insertion and positioning capabilities.
Solution Approach 2:
The single device performs multiple functions: it can insert the pipe lining into the pipe using the winding device, and subsequently position the inserted pipe lining using the calibration hose. The device is designed to handle both operations that previously required separate equipment.
2Adaptability or versatility
If multiple devices are used for insertion and positioning, then the required functions are achieved, but the ease of operation deteriorates
Solution Approach 1:
By merging the insertion and positioning functions into one device with a unified housing and control system, the operator deals with a single piece of equipment rather than coordinating multiple devices. This simplifies the operational workflow and improves ease of use.
3Adaptability or versatility
If separate devices are used for insertion and positioning, then the functions are performed, but the productivity deteriorates
Solution Approach 1:
The integrated device allows continuous operation where the pipe lining can be inserted and then immediately positioned without removing or replacing equipment. The calibration hose can be fed through the housing directly after the pipe lining insertion, eliminating downtime and improving overall productivity.
