Laser Line Beacon Positioning in Disturbed Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser positioning systems are unable to accurately determine the absolute position of elements in environments with external disturbances such as fog, rain, wind, and mechanical vibrations, as these disturbances attenuate or displace the laser beam, making it difficult to achieve precise alignment and measurement.
Innovation Solution
A laser positioning system comprising a laser line beacon and a laser line receiver, where the laser line beacon is mounted on a moveable carriage along a story pole and uses a fiber optic bundle with a duo-lateral sensor to intercept and process the laser signal, providing accurate positioning information even in disturbed environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a laser beam is used for positioning, then measurement precision is improved, but reliability deteriorates in environments with external disturbances such as fog, rain, or mechanical vibrations
Solution Approach 1:
The system employs a feedback mechanism where the laser receiver detects the position of the laser beam and sends signals back to the laser source. This feedback loop enables real-time compensation for disturbances such as mechanical vibrations and environmental factors, allowing the system to maintain both high measurement precision and reliability in challenging conditions
Solution Approach 2:
The patent introduces an intermediary stabilization system between the laser source and receiver. This intermediary component actively compensates for disturbances by adjusting the laser beam path or receiver position, thereby maintaining reliable operation and precise measurements even in the presence of fog, rain, or mechanical vibrations
2Reliability
If stabilization techniques are used to reduce mechanical disturbances, then reliability is improved, but device complexity increases
Solution Approach 1:
The laser positioning system incorporates self-service capabilities through automatic disturbance compensation. The system autonomously detects and corrects for mechanical disturbances and environmental interference without requiring complex external stabilization equipment, thereby improving reliability while keeping device complexity manageable
Solution Approach 2:
The patent replaces complex mechanical stabilization systems with an optical-electronic solution. By using laser feedback and electronic signal processing to compensate for disturbances, the system achieves high reliability without the mechanical complexity of traditional stabilization mechanisms

AI summary
A laser positioning system is described. The laser positioning system provides a positioning and guidance system that is suitable for environments that have external disturbances such as those caused by wind, equipment movement, vibration, and the like. The laser positioning system of the present invention uses at novel laser line beacon positioning system in optical communication with a novel laser line receiver to achieve accurate positioning in environments with external disturbances, something that has previously not been attainable. In some embodiments, a target or series of targets are used to create a reference by which the laser line receiver and an associated moveable assembly such as a robotic arm assembly are able to accurately place building elements such as bricks. Exemplary applications of the laser positioning system include, but are not limited to, accurate positioning of bricks in a wall under construction by a robotic brick laying system.
