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.
- Mesh Stent Expansion for Partially Collapsed Pipe Relining
Expandable mesh stents reopen partially collapsed pipes without overlapping sections, preserving flow and supporting minimally disruptive relining.
- Drainage Channel Bottom Ditch Curvature Prevents Water Stagnation
A drainage channel uses a bottom ditch with a second radius of curvature to prevent water accumulation and bacterial growth at the base.
- Hydrophilic Gasket Sealing Apparatus for Sewer CIPP Liner Annular Space
A locking sleeve with a hydrophilic gasket seals the annular space created by CIPP liner shrinkage, preventing infiltrate entry into the sewer system.
- Stackable Multi-Part Gutter Stepped Joining Mechanism
Stepped joining guides side walls into a trough, accommodating large tolerances to ensure leak-tight connections without complex assembly tools.
