Sewerage Structures TRIZ Cases

Segmented inlet openings and asymmetric connecting means prevent elongated drain cover rotation while increasing water drainage capacity.

Deformed draw necks form lamination-retention collars that cover sharp edges on the securing portion, eliminating finger cut hazards.

Expanding conduit adjusts fluid passageway position via internal pressure to maintain consistent discharge rates.

Segmented adapter prevents undercuts between circular drains and bituminous surfaces, enabling direct compaction.

Longitudinal drainage slots separate walking comfort from overflow safety, resolving the trade-off between barefoot stability and high water throughput.
