Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vibration testing methods for computer systems are time-consuming and costly, often only testing in one rack slot, which may not represent the vibrations in other slots, leading to incomplete assessment of performance degradation due to vibrations.
Innovation Solution
A method and system that generates a composite vibration profile in a frequency range by measuring vibration spectra across various configurations, including permutations of location and operational modes, and using accelerometers to determine the highest amplitude vibrations, allowing for a comprehensive vibration testing of computer systems in a rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration testing is performed on computer systems in rack configurations, then the reliability of performance assessment is improved, but the testing time and costs increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-measuring vibration spectra in various rack slot configurations and generating a composite vibration profile before actual performance testing. This pre-characterization of the vibration environment allows subsequent performance tests to be conducted more efficiently without repeating exhaustive vibration measurements, thus improving reliability while reducing testing time.
Solution Approach 2:
The patent creates a composite vibration profile that copies and represents the aggregate vibration characteristics of multiple rack slot configurations. Instead of physically testing each configuration separately, the composite profile serves as a representative model that captures the essential vibration features, allowing reliable assessment without the time cost of exhaustive physical testing.
2Reliability
If vibration testing is performed on computer systems in rack configurations, then the reliability of performance assessment is improved, but the testing costs increase
Solution Approach 1:
The patent creates a composite vibration profile that copies and represents the aggregate vibration characteristics of multiple rack slot configurations. Instead of physically testing each configuration separately, the composite profile serves as a representative model that captures the essential vibration features, allowing reliable assessment without the time cost of exhaustive physical testing.
Solution Approach 2:
The composite vibration profile serves as a universal representation that can be applied to assess multiple different rack configurations and slot arrangements. This multi-functional approach allows a single composite profile to provide reliable performance assessment across various configurations, reducing the need for separate expensive testing setups for each scenario.
3Loss of time
If only one rack slot configuration is tested, then the testing time and costs are reduced, but the measurement precision of vibration impact is insufficient
Solution Approach 1:
The patent merges vibration spectrum data from multiple different rack slot configurations into a single composite vibration profile. By combining the spectral characteristics from various configurations, the composite profile achieves higher measurement precision that represents the overall vibration impact, while avoiding the time cost of separately analyzing each configuration.
Solution Approach 2:
The patent creates a composite vibration profile that combines spectral characteristics from multiple configurations, analogous to creating composite materials with enhanced properties. This composite representation integrates the vibration features of different configurations to produce a more precise and comprehensive characterization than any single configuration could provide alone.
