Branch Liner Installation Through a Single-Access Rotating Inflator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe renovation systems for lining branches and junctions are complex, requiring multiple access points and personnel to manage wires, rods, and hoses, making the installation process cumbersome and time-consuming.
Innovation Solution
A single installation device with a control unit and expansion unit, featuring a flexible duct and shaft system that allows for rotation and inflation of a branch piece within a pipeline, enabling a single user to position and secure a branch liner with pressurized air or steam, reducing the need for multiple entry points and personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate branch pieces with multiple pulling wires and push rods are used, then the branch piece can be positioned at the branch position, but the system becomes complicated and requires multiple access points and personnel
Solution Approach 1:
The patent combines multiple separate components (pulling wires, push rods, air hose) into a single integrated installation device with a unified shaft system. The control unit and expansion unit are merged into one device that can be inserted through a single access point, eliminating the need for multiple separate components and multiple personnel operations.
Solution Approach 2:
The installation device performs multiple functions through a single unified structure. The shaft system can both push and pull the branch piece, the single access point allows insertion and retrieval, and the integrated design handles positioning and securing operations without requiring separate specialized tools for each function.
2Manufacturing precision
If multiple employees work in cooperation to place the branch piece, then correct positioning can be achieved, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The installation device is designed to automatically position and secure the branch piece through its integrated shaft system and expansion mechanism. The device self-adjusts and self-positions the branch piece at the correct location without requiring multiple personnel to manually guide and secure it, thereby maintaining positioning accuracy while reducing labor requirements and installation time.
3Ease of manufacture
If access to the branch position is obtained through more than one pipe, then the branch piece can be installed, but the procedure becomes cumbersome and requires multiple entry points
Solution Approach 1:
The patent merges all installation functions into a single device that can be inserted through one access point. The control unit and expansion unit are combined into one integrated system that travels through a single pipe to reach the branch position, eliminating the need for multiple separate access points and the complexity of coordinating multiple insertion paths.

AI summary
An installation device (2) for installing a branch liner in a branch point of a pipeline is disclosed. The device has a body (4) with an inlet (16) defined therein for fluids and a turning knob (10) is rotatable relative to the body (4). The turning knob (10) is attached to a first shaft (32) and the opposite end of the first shaft (32) is attached to a first barrel (40). The device further comprises a second barrel (60) and a second shaft (50) attached between said barrels (40, 60). The device further comprises a duct (30) extending between the body (4) and the first barrel (40) forming a passage (17, 31) for fluids from the inlet (16) of the body (4) to an area between said first barrel (40) and said second barrel (60).
