Tubular Articles TRIZ Cases
- Movable Heating Furnace for Versatile Heat Shrink Tube Processing
A movable heating furnace travels along a clamped cable to shrink tubing efficiently across different cable lengths with less bulk and complexity.
- T-Bar Cylindrical Member Spinning for Integral Plastic Forming
Staged shear, flow, fractal, and flat spinning forms T-bar cylindrical members at room temperature with better material use and lower energy.
- Grooved Composite-Metal Rod Joint With Hoop Reinforcement
Circumferential grooves and a composite hoop reinforcement create a simpler composite-metal rod joint that improves load transfer and resists slippage.
- Variable-Thickness Tube Hydroforming for Complex Cross Sections
Circumferential wall-thickness variation controls strain during hydroforming, enabling one-piece tubes with complex cross sections without bursting or wrinkling.
- Dual-Mandrel PEX Expansion Tool for Faster Uniform Tube Expansion
A dual-mandrel jaw mechanism cuts PEX expansion cycle time to one second or less while maintaining even force distribution for secure fitting insertion.
- Dual-Mandrel PEX Expansion Jaws for Uniform One-Second Cycling
Coordinated first and second mandrels drive PEX expansion jaws for uniform tube expansion and rapid fitting installation within one second.
- Angled-Fiber Tubular Liner for Circumferential Stretch and Fit
Angled transverse fibers let a resin-impregnated tubular liner expand circumferentially, fit old pipes better, and install at lower pressure.
