Sewer Pipelines TRIZ Cases
- Sewer Rehabilitation Packer With Segmented Flexibility for Bends
Segmented stiffness lets this sewer rehabilitation packer pass sharp bends, hold flange spacing, and use a front camera for precise placement.
- Pipe Rehabilitation Power Module Using Supercapacitors for Safe Cutting
A supercapacitor power module lets a pipe cutter run from sub-60V DC, reducing cable weight and safety hazards without interrupting other functions.
- Mesh Stent Expansion for Non-Overlapping Collapsed Pipe Repair
Radial mesh stent expansion restores collapsed pipe sections without overlap, easing relining and preserving hydraulic conductivity.
- Adjustable Pipe Expander for Confined-Space Liner Installation
Expandable pads and removable jackets let one pipe expander fit varying host diameters, supporting confined-space pipe relining with less host damage.
