Sewerage Structures TRIZ Cases
- Adjustable Height Compression Drain for Shower Installations
An adjustable-height compression drain resolves the trade-off between simple construction and precise waste pipe positioning.
- Elongated Retaining Element for Wastewater Coarse Matter Separation
An elongated retaining element extends along a storage sewer channel to separate coarse contaminants from wastewater flow.
- Pollution Control Valve Isolates Drainage System
A pivotable panel valve isolates interceptor tanks from mains drainage networks using pressurized fluid actuators.
- Drainage Gutter U-Profile Frame Weight Diversion
One-piece folded frame design resolves complexity trade-offs by diverting load forces through a U-profile to enhance structural stability.
- Modular Drain Assembly for Pod Room Plumbing Alignment
Segmented drain outlets align with building pipes while maintaining pod stability.
- Drain Armature Magnetic Centering Inclined Sliding Surfaces
An inclined sliding surface converts magnetic force into a centering action that restores the drain armature position after external loads displace it.
- Culvert Rinsing via Sudden Water Level Drop
Sudden water level drops create high-energy flows that remove deposits and prevent backpressure in waste water channels.
- Soil Matrix Water Table Control via Perforated Pipe and Overflow Controller
Segmented drainage pipes and gravity-based overflow controllers maintain optimal water tables to enhance contaminant removal without complex automation.
- Manhole Bait Housing with Dynamic Water Seal
A manhole bait housing uses a dynamic closing body to seal passage openings and contain rodenticide within the apparatus.
- Removable Catch Basin Filter Insert for Stormwater Pollution Capture
A removable catch basin filter insert captures stormwater pollutants while allowing water to pass through at normal flow rates.
- Integrated Fence Dike for Epoxy Containment in Semiconductor Equipment
An integrated fence design merges wall components to prevent epoxy leakage at corners while simplifying installation.
- Modular Underground Fluid Detention System with Circuitous Flow Paths
Precast concrete modules arranged in rows and columns create circuitous fluid flow paths to retain water underground while maintaining structural integrity.
- Earthing Metal Tube via Sliding Ring Clamp
A sliding metal ring clamp secures an earthing connection to a conductive tube without breaking the drain sealing membrane.
- Adjustable Floor Drain Assembly for Post-Pour Height Alignment
Segmented components enable post-pour height adjustment, resolving installation complexity while ensuring precise alignment.
- Adjustable Drain Assembly Leveling Mechanism for Floor Variance
Adjustable drain assembly uses a threaded leveling member to position the strainer flush with the finished floor surface.
- Interlocking Modular Drainage Channel for Façade Length Adjustment
Segmented channel elements engage via positive locking features to enable variable length adjustment without tools, resolving assembly handling difficulties.
- Odor Trap Partition Wall Segmentation for Hair Clogging
Partition wall divides liquid flow into separate pathways within an odor trap to prevent hair entanglement.
- Sanitary Drain Housing with Height-Adjustable Frame
A detachable frame on a drain housing enables post-screed sealing and height adjustment, resolving alignment complexity during sanitary fitting installation.
- Foldable Rainwater Delay Device for Cloud Burst Management
A foldable rainwater delay device stores excess runoff in a flexible bag to manage sudden flow volumes.
- Floor Drain Sealing Mat and Water-Sealing Layer Integration
A floor drain assembly integrates a pre-adhered water-sealing layer with an overlapping sealing mat to create a watertight barrier on the peripheral flange.
- Gas Valve Segmentation for Liquid Sealing and Vacuum Response
Segmented gas valve design prevents system collapse by admitting ambient air during pressure drops while the float seals against liquid discharge.
- Rotary Air Admittance Valve With Guide Rails
A rotary valve with guide rails admits air under vacuum pressure while maintaining a seal against harmful gases and corrosive environments.
- Slatted Floor Animal Waste Management System
A slatted floor structure separates animal waste into liquid and solid streams for efficient basement collection.
- Light Shaft Drain Cover with Segmented Sieve and Sealing Rib
Segmented sieve and sealing rib in light shaft drains prevent sand ingress while simplifying blind installation.
- Tile Strengthening Profile for Drain Cut-Outs
A tile with a cut-out opening integrates a strengthening profile to maintain structural integrity during installation.
- Recessed Point Drain Assembly for Flush Tile Installation
A recessed point drain assembly sits below the subfloor level to enable flush tile installation.
- Cycling Siphon Valve with Magnetic Float for Gas Buildup
A magnetic float valve cycles a siphon to evacuate liquid, preventing gas bubble obstruction at low flow.
