Surveyor'S Staffs TRIZ Cases

This case uses a 10–50 mm spherical reflector with a protruding aiming mark to avoid realignment while preserving precise surveying.

GNSS position data and difference imaging guide the telescope toward an optical transmitter for rapid target relocking.

An offset EDM and redirected light path measure telescopic surveying pole length while limiting top-unit size and weight.

An offset EDM and optical redirection measure telescopic pole length while reducing top-unit diameter and weight for easier handling.

This case uses segmented curved retro-reflecting elements to reduce prism weight and lateral aiming errors during precise surveying.

A rover system integrates GNSS and inertial sensors to determine position without external reference instruments.

Rigidly connecting a code element and line sensor at fixed spacing determines inclination via optical projection, reducing device complexity.

A leveling system uses fluorescent depth-indicator targets struck by a light plane to visually signal surface height variations.

Wide-angle lens system captures multiple level staff images to calculate collimation heights simultaneously, eliminating sequential reading delays.

An adjustable prism corner stand positions a measurement prism relative to a distance measuring device.

Corrects positional drift in dynamic environments by combining laser-based reflector measurements with image-based visual design orientation.

An IMU sensor combined with a Kalman filter algorithm calculates accurate attitude angles, eliminating manual leveling errors caused by magnetic disturbances.

A traveling inspection device deposits color-coded marks on surfaces to visually indicate height differences from a reference level.

A sensor rod assembly with a controller detects laser light to determine elevation adjustments.
