Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the remaining service life of components in devices are inefficient and require high computing effort, especially during operation, and do not allow for real-time damage assessment.
Innovation Solution
A method that involves providing load-specific reference data in an evaluation unit, sensing actual load-specific data using a load sensing system, and scaling these data to calculate theoretical damage and remaining service life, enabling quasi-real-time damage assessment with reduced computing effort during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to determine remaining service life, then damage calculation is performed, but computing effort is high and real-time assessment is not possible
Solution Approach 1:
The patent pre-calculates and stores damage values for various load collectives in a database before actual operation. During operation, the system only needs to retrieve and combine pre-computed damage values based on sensed load data, avoiding complex real-time damage calculations and enabling rapid assessment with minimal computing effort.
2Measurement precision
If detailed damage calculation is performed, then remaining service life can be determined, but the process is time-consuming and cannot be performed in real-time
Solution Approach 1:
The system pre-computes damage values for various load collectives and stores them in a database. During operation, it senses actual load data, retrieves corresponding pre-computed damage values, and combines them to determine total damage and remaining service life. This approach maintains accurate damage determination while reducing calculation time from hours/days to seconds.
3Reliability
If continuous monitoring is implemented, then real-time damage assessment is possible, but computing resources are consumed during operation
Solution Approach 1:
The system performs all computationally intensive damage calculations beforehand and stores results in a database. During continuous monitoring operation, it only retrieves pre-computed damage values based on sensed load data and performs simple summation. This enables real-time damage assessment with minimal energy consumption during operation.

AI summary
A method for directly determining a theoretical damage of at least one component of a device includes providing load-specific reference data in an evaluation unit, sensing actual load-specific data by a load sensing system, and transmitting the actual, load-specific data to the evaluation unit. The actual load-specific data includes classified load collectives comprising a dwell time of occurring damage variables at defined load levels, a number of load changes of occurring damage variables, and an event count of occurring damage variables. The method further includes scaling the load-specific reference data to the actual load-specific data for calculating the theoretical damage of the at least one component and determining a remaining service life.
