Solution Overview
Problem
Vibration test devices face challenges in accurately diagnosing current and future failures due to varying deterioration rates under different test conditions, making it difficult to maintain their accuracy and prevent equipment failure.
Innovation Solution
A vibration test support network system connects multiple vibration test devices via a network, enabling the sharing and analysis of self-diagnosis information, remote diagnosis, maintenance data, and vibration test data to predict failures and determine maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If self-diagnosis is performed using only local data from individual vibration test devices, then device complexity is reduced, but measurement precision of failure diagnosis deteriorates due to varying deterioration rates under different test conditions
Solution Approach 1:
The patent combines self-diagnosis data from multiple vibration test devices into a unified database, merging local diagnostic capabilities with centralized data analysis to improve failure diagnosis accuracy while distributing system functions
Solution Approach 2:
The patent introduces a diagnostic support system as an intermediary that collects, stores, and analyzes self-diagnosis data from multiple devices, providing refined failure predictions without requiring direct complex inter-device communication
2Productivity
If vibration test devices operate continuously without maintenance to maintain productivity, then productivity is improved, but reliability deteriorates due to increasing crosstalk and potential shaker failure
Solution Approach 1:
The patent performs preliminary failure prediction by continuously monitoring self-diagnosis data and comparing it against learned patterns, enabling maintenance to be scheduled before actual failures occur, thus maintaining both productivity and reliability
Solution Approach 2:
The patent implements a feedback mechanism where self-diagnosis results are continuously fed back to the diagnostic support system, which refines failure predictions and provides maintenance recommendations to prevent shaker failures during operation
