Oilsumps TRIZ Cases

A segmented housing frame, cover, and base form sealed oil channels and a suction path, cutting sump size while simplifying manufacture.

A dual-pump reservoir with a baffle plate maintains fluid supply during cornering while reducing air intake, space use, and pump load.

Integrated channels in a multi-part oil sump housing save space, simplify molding and sealing, and maintain stable lubrication during cornering.

Stored engine waste heat in a light-triggered phase-change reservoir warms oil quickly for cold starts without prolonged electric preheating.

An integral crankcase reinforcing plate boosts opening rigidity, stabilizes the oil strainer, and suppresses oil pan vibration noise.

Dual plug locations and a symmetric attachment let one oil pan fit either engine orientation while keeping the oil syphon aligned.

A plastic oil filter body and cover cut weight, simplify cartridge changes, and keep engine oil flowing through a bypass valve when clogged.

An axially sliding lock ring stops oil pan drain plug loosening without release torque, reducing breakage risk in cold climates.

A porous core inside a double-walled lubricant pan improves oil cooling and warming while removing the need for a separate heat exchanger.

A sealed sump-integrated heat exchanger cuts corrosion, assembly complexity, and coolant pressure drop while maintaining oil cooling.

A resin filler around the balancer shaft reshapes crank chamber oil flow to cut stirring resistance, turbulence, and engine output loss.

A two-part frame and gasketed flange enable pre-assembled floating oil sump mounting that reduces leakage risk and preserves vibration isolation.

A split frame with internal fixation and gasket-clamped flange enables a floating oil sump mount that eases assembly and prevents leaks.

Internal ribs and a drainage column stiffen a non-metallic lubricant pan, improving durability while preserving weight and cost benefits.

Intersecting webs, selective vent openings, and shaped lubricant passages manage crankcase drainage while preserving pan rigidity.

Rotational symmetry and dual plug portions let one composite oil pan fit two orientations and simplify engine assembly.

Oil separation filters extract hydrocarbons and soot from crankcase gases, preventing compressor wheel fouling in forced induction engines.

Composite construction with metal ribs and an angled drain spout resolves material fatigue risks in plastic oil pans.

A partition wall isolates the rotating pinion from the main oil reservoir, preventing foam generation and ensuring reliable lubrication.

An additive fixture houses friction modifier sections within the lubrication circuit to continuously release chemicals into circulating oil.

An oil accumulation ramp with tuned air return ports separates the sump from the crankcase, reducing parasitic losses and oil aeration.
