Casings TRIZ Cases

A bearing holder forms a gas-liquid separation chamber with a cover member to separate oil mist from air in an engine crankcase.

A chain saw engine attaches to a polymer housing using specific fixing members to anchor the assembly and reduce operational vibration.

A block insert guides cooling water flow velocity through a dedicated hole to prevent excessive temperature rise in the siamese portion.

A compact multi-unit vehicle cooling system integrates five coolers into a single modulated package.

Base plate with integrally formed engine mountings secures the powertrain while reducing vehicle weight.

Integral crankcase protrusion forms the water pump body, eliminating lateral tubing damage and improving aesthetic appearance.

A sensor support structure with a radial arm and restriction portion positions a camshaft rotation sensor on an engine cylinder head cover.

A camshaft assembly uses parallel contact surfaces on bearing blocks to align the unit with the cylinder head bore axis during installation.

Segmented clips provide accessible gripping points in packed engines, resolving automation and manufacturing complexity trade-offs.

A cylinder head mantle forms a closed pressure fluid circuit for valve actuators.

Mirror-image gear sets drive pistons along a trochoidal path, resolving the contradiction between fixed compression ratios and variable engine performance.

Three centering pin bores in the interface casing enable precise concentricity alignment while eliminating production costs for specific pin positions.

An external securing part locks the camshaft in a receiving element, preventing gear damage and reducing assembly time.

Segmenting the oil supply into a main line and sub-supply pipe prevents bearing starvation when engine layout changes or shaft length increases.

Lateral repositioning of the air intake manifold exposes the common rail to engine fan airflow, preventing thermal damage and excessive fuel temperature rises.

A cylinder head pre-separator uses a calming space to agglomerate oil drops from blow-by gases.

Positioning the ventilation vessel above the inlet manifold reduces coolant volume and hose length, accelerating engine warm-up.

A detachable crankcase bottom plate and inverted camshaft layout enable direct component access without removing the crankshaft.

A breather chamber forms between the crankcase and V-belt transmission case to separate oil mist from engine gases.

A control device defines setpoint pressure values for internal combustion engine operating points to monitor crankcase conditions.

A vehicle ignition plug cooling device uses separate air flow passages and oil chambers to cool plugs within the cylinder head.

An asymmetric crank and connecting rod mechanism modifies piston motion via a roulette path to resolve compression ratio trade-offs.

Inclined cylinder head flanges merge sealing functions into the head structure, reducing part count and manufacturing complexity.

Applying a thermal gradient during welding prevents hollow element deformation while maintaining joint strength and acoustic performance.

Segmenting the groove into a hard plastic member prevents boundary steps that compromise sealing performance.
