Solution Overview

Problem

Conventional system tests for laser processing systems require a significant duration, necessitating the patient to be in a treatment-ready state for an extended period, causing discomfort and potential stress due to thermal drifts and mechanical changes, which can be minimized by overlapping functional tests and parameter ascertaining in time to reduce overall test duration.

Innovation Solution

A method and control unit for laser processing systems that perform functional tests and parameter ascertaining simultaneously, allowing for a reduced overall test duration by overlapping these processes, enabling tests and calibrations to be conducted without extending the patient's constrained position or treatment preparation time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If system tests are carried out sequentially one after another, then measurement precision and reliability are ensured, but loss of time increases significantly

Engineering Contradiction:
Improvemeasurement precisionVSAvoidtest duration
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements continuous useful action by overlapping the functional test of the control element with the ascertainment of variable parameters. Both processes run simultaneously rather than sequentially, eliminating idle time between operations. The control unit executes the functional test while concurrently measuring parameters such as contact glass position, maintaining continuous productive activity throughout the system test duration.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent merges two previously separate processes into a unified simultaneous operation. The functional test of the control element and the ascertainment of variable parameters are combined into a single overlapping time window, where both processes occur concurrently. This merging reduces the total test duration from the sum of both processes to approximately the maximum of the two individual process durations.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If all tests and calibrations are carried out directly before treatment, then reliability of treatment is improved, but loss of time increases causing patient discomfort

Engineering Contradiction:
Improvereliability of treatmentVSAvoidpatient preparation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies continuous useful action by ensuring that all necessary tests and calibrations are performed in an overlapping manner directly before treatment. The functional test and parameter ascertainment run simultaneously, minimizing the total time the patient must remain in the constrained docked position while ensuring all reliability checks are completed immediately before therapy begins.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A method for carrying out a system test of a laser processing system is disclosed. The method includes the execution of a functional test of a control element of the laser processing system. The method further includes the determination of a variable parameter and the determination of an influence of the determined variable parameter on an intended execution of a laser processing by means of the laser processing system. The execution of the functional test of the control element and the determination of the variable parameter overlap at least partially in time.
