Solution Overview

Problem

Existing control and monitoring systems for rotating lasers lack effective mechanisms to dynamically adjust laser power based on rotational speed, leading to potential safety issues and inefficient operation.

Innovation Solution

A control and monitoring device with dual regulating units that adjust the rotational speed and laser power of a rotating laser head, using sensors and feedback loops to ensure the laser power remains within safe limits, and includes a blocking or deflection unit to prevent unsafe emission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If laser power is controlled as a function of rotational speed by a single control unit, then the system structure is simple, but safety and reliability are insufficient

Engineering Contradiction:

ImprovesafetyVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control system is segmented into two independent control units: a first control unit that controls laser power as a function of rotational speed, and a second control unit that independently monitors rotational speed and controls laser power. This segmentation provides functional redundancy, ensuring that if one control unit fails, the other can maintain safe operation, thereby resolving the contradiction between system simplicity and safety reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements beforehand cushioning by establishing a predetermined safe operational relationship between rotational speed and laser power in the second control unit. This pre-programmed safety logic acts as a protective buffer that automatically limits laser power to safe levels based on rotational speed, preventing unsafe conditions even if the primary control system fails.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Adaptability or versatility

If a single control unit is used, then the device is simple to operate, but dynamic adjustment capability and safety are insufficient

Engineering Contradiction:

Improvedynamic adjustment capabilityVSAvoidoperation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the functions of two control units into a single integrated control device housing. While the internal control logic remains dual-unit for safety and adaptability, the external interface presents a unified, simple operating panel. This merging allows the system to maintain high dynamic adjustment capability through independent control channels while preserving ease of operation through a single user interface.

AI summary

The disclosure proceeds from a method for operating a control and monitoring device for a rotating laser, wherein in one method step, a laser power of a laser unit of the rotating laser is controlled as a function of a rotational speed of a rotating head of the rotating laser by means of a control or regulating unit of the control and monitoring device. By means of a further control or regulating unit of the control and monitoring device, the rotational speed of the rotating head and at least one operating parameter of the laser unit is interrogated and adjusted in order to emit a signal for influencing a laser beam that can be emitted by means of the laser unit.
