Optically Investigating Flaws/Contamination TRIZ Cases

Liquid sealing and air jetting expose small laser-weld defects as bubbles, enabling fast and accurate on-line inspection.

Interchangeable housings and a dichroic mirror let photodetectors be rearranged for more accurate returned-light measurement in laser welding.

Separating the camera and control units lets electrode inspection fit near robots while the metal control housing dissipates heat during continuous use.

Deflected-light inspection detects debris on a laser scanner optical surface before ablation, preserving laser power and surface quality.

A flexible camera and lighting mount speeds production line inspection setup while preserving image quality and easy repurposing.

Tracks inspection standard changes with time-linked history and approval data to reduce false rejects, missed defects, and line inefficiency.

Circular light reflection analysis checks weld quality from local geometry, reducing dust-driven errors and inspection time.

Multiple laser lines and camera imaging measure coil telescoping more accurately before transfer, improving coiling quality in hot-rolling lines.

Vision imaging checks unitary protrusions for holes, incomplete forms, and breakage, improving substrate quality control and reducing waste.

Combining LIDAR and structured laser data in one pipe pass improves feature imaging accuracy while reducing inspection time and cost.

Optical sensing of thermal, visible, and reflected light gradients identifies laser welding focal shifts before joint defects occur.

Optical signal features and a trained model pinpoint molten shape abnormality position, number, and size during laser lap welding.

Relative laser scanning and reflection analysis pinpoint beveled disk edges between sensor intervals to improve processing accuracy.

Reflective coating on protective-glass and holder surfaces boosts scattered-light sensing, enabling earlier contamination detection.
