Connecting Rods TRIZ Cases

Standardized CNC-made screw rod sections use measured thread entry points and contact planes to enable interchangeable assembly without manual labeling.

Cooling oil from the piston is routed through the connecting rod to lubricate the bearing, avoiding crankshaft bores and lowering oil demand.

Automatic holding-element release lets formwork supports lower without manual deactivation, cutting time, labor, and crane dependence.

A pivot guard and lifting cylinders let engineers add or remove an intermediate plate to change compression ratio without connecting rod disassembly.

A spring-loaded sleeve engages anti-rotation forms to stop unwanted pivoting while still allowing threaded rod and tube length adjustment.

Concealed electrical and mechanical joints inside diffusing light bodies keep modular LED fixtures easy to assemble and uniformly illuminated.

A metal liner between composite layers spreads localized landing gear loads, preserving strength while reducing structural weight.

A nodular cast iron rod reinforced at the shank cuts engine weight and cost while maintaining steel-like strength, stiffness, and damping.

Pressurized oil is stored and delivered through the connecting rod port to prevent seizure when short non-press periods limit lubrication.

A friction brake on the threaded coupling rod enables stepless distance adjustment while preventing unwanted position changes under torque.

Non-symmetric crank web protrusions scoop and compress the air-fuel mixture to raise two-stroke tractive force and power.

A gearbox-driven screw rod adjusts tie rod length in place under load, avoiding unpinning, tools, and repeated installation delays.

A spring-loaded sleeve engages anti-rotation forms to hold rod-tube length, then disengages for easy screwing and unscrewing.

Localized carbon control on the oil-hole inclined surface raises bending-stress resistance, prevents cracking, and avoids costly alloying.

One-degree-of-freedom links and a low-stiffness roll constraint cut torque vibration transmission while keeping engine deflection low.

A torque linkage and guide structure convert piston travel to rotary output while removing seal side loads and preserving a compact envelope.

A separate wave-profile damping element and threaded insert cut transmission vibration to the gear shift lever while simplifying assembly.

Controlled coarse TiN inclusions let bainitic hot-forging steel split brittlely while retaining yield strength, fatigue strength, and machinability.

A hydraulic chamber with an auxiliary chamber shifts top dead center to vary compression ratio while suppressing peak combustion pressure.

Integrated cut-off valves seal hydraulic conduits without binding the contact element, reducing leakage and stabilizing piston rod position.

An expandable mandrel drives pre-impregnated fibers into coupling splines, reducing porosity and improving fatigue resistance.

A protuberant lobe joint locks a metal attachment into a composite tube to transfer axial and bending loads without slipping.

A movable stop and contact element let a helicopter control rod switch between limited and extended adjustment for faster tuning and lower vibration.

A pin-and-cable locking assembly secures threaded couplings while cutting weight and length and preventing lock nut loosening under vibration.

A tapered, toothed end fitting engages multiple composite shaft layers at once to improve load transfer and reduce delamination risk.

A segmented connecting rod uses offset and fixed support points to hold the piston near top dead center longer, improving combustion and reducing tilt.

Curved captive end fittings and axial preloading help composite joints transmit load while reducing fretting, wear, and bonding complexity.

A post-assembly interference-fit preload strengthens composite shaft end joints, improving fatigue resistance while limiting assembly heat and weight.

A curved connecting rod increases piston stroke and air exhaust while reducing lateral pressure and cylinder-wall friction in compressors.

Grooved bushings and PTFE liners keep grease flowing around the rotation rod, limiting bypass, wear, and maintenance in landing gear linkages.

A yoke assembly keeps the connecting rod moving only on the bore axis, removing secondary imbalance loads on crankshafts and bearings.

A wear-resistant sleeve inside the inner ring prevents shaft fretting, improves axial retention, and extends ball joint service life.

Hydraulic chambers, check valves, and a throttle stabilize connecting rod length adjustment while preserving preload for variable compression engines.
