Material Analysis Using Sonic/Ultrasonic/Infrasonic Waves TRIZ Cases

Removing slag and other weld-surface impurities before laser ultrasound inspection improves internal defect detection reliability.

Rotationally offset transducers and adjustable wall spacers keep a free-swimming ultrasonic module centered and reduce cross-talk in pipeline inspection.

A motorized carriage moves maintenance tools through the turbine cavity to reach non-rotating parts, enabling in-situ inspection and repair with less downtime.

A two-piece measurement duct shapes a V-path ultrasonic reflection to improve focusing, suppress out-of-phase signals, and keep a fluid-tight seal.

An ultrasonic smart ball uses cavitation to remove pipe scale while tracking buildup locations for real-time pipeline maintenance.

Multi-stage scanning builds a 3D rotor model, flags areas of interest, and directs contact probing for faster, more precise defect inspection.

An auxiliary spring and bearing link add adjustable gravity compensation to ultrasound arms without replacing fixed-pressure gas springs.

Known contaminant defects are embedded at seamless diffusion-bonded interfaces to create practical NDI standards for internal void and porosity detection.

Releasable ultrasonic sensor bars let one pig supporting structure adapt to different pipeline sizes while cutting part complexity and cost.

Ultrasonic sensing on the welding electrode maps weld reflections in real time, replacing slow visual and destructive joint inspection.

Real-time ultrasonic tilt feedback shows probe orientation and tolerance range, helping inspectors correct weld inspection alignment.

A spacer wedge offsets paired transducer wedges to inspect welds in normal and transverse directions in one pass while reducing beam interaction.

Partial pre-curing of selected adhesive regions creates controllable kiss-bond and weak-bond test blocks for mechanical defect evaluation.

Articulated wheel units and lockable arms let the robot grip small, bent, and branched pipes for stable positioning and ultrasonic inspection.

A detachable rod-and-base bracket uses transverse force locking and limit features to speed setup, improve transport, and avoid screw wear.

Thermosonic gold bump bonding joins a bulk acoustic wave sensor die to a slotted PCB without flux, avoiding active-surface contamination and wash damage.

Vibration stimulation combined with optical sensing improves weed-crop identification under occlusion, lighting variation, and leaf damage.

Ultrasonic and radar fusion helps an autonomous snow sweeper detect obstacles and approaching creatures with fast filtering and fewer false alarms.

A guide wheel riding the conduit invert lets this remote crawler measure alignment, grade, distance, and deflection for faster quality control.

An acoustic metamaterial coating lets external sensors monitor buried pipelines remotely, improving corrosion and leak detection without pigs.
