Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic techniques fail to accurately diagnose vibration phenomena in machines with diverse mechanical structures, as they rely on specific structural conditions and are inadequate for machines with various mechanical parts using motors as drive sources.
Innovation Solution
A diagnostic apparatus that stores information on vibration phenomena associated with videos, allowing users to select and diagnose vibration types by viewing videos of different phenomena, providing diagnostic results based on user selections, enabling accurate on-site diagnosis for users with less knowledge and experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vibration waveform data analysis is used for diagnosis, then diagnostic capability is provided, but accurate diagnosis fails for machines with diverse mechanical structures
Solution Approach 1:
The patent creates video copies of actual vibration phenomena occurring in machines, storing them as reference materials. Users can compare their observed vibration phenomena against these video copies to identify and diagnose vibration issues accurately, regardless of the specific machine structure. This copying approach allows the diagnostic system to adapt to diverse mechanical structures without requiring structure-specific analysis algorithms.
2Measurement precision
If expert knowledge is required for vibration diagnosis, then accurate diagnosis can be achieved, but diagnostic time increases and expert intervention is needed
Solution Approach 1:
The patent enables users to perform vibration diagnosis themselves by providing them with video references of various vibration phenomena and a structured comparison methodology. Users can independently identify and diagnose vibration issues by comparing their observations against the video library, eliminating the need to call experts for routine diagnoses. This self-service capability reduces diagnostic time and empowers users with less knowledge to handle vibration problems effectively.
3Ease of operation
If vibration diagnosis is performed without visual references, then diagnostic process is simplified, but diagnostic accuracy decreases for users with less knowledge
Solution Approach 1:
The patent introduces video references as an intermediary between the user and the vibration phenomenon. These videos serve as visual mediators that help users understand and identify different types of vibrations by comparing their observations with the video examples. This intermediary approach maintains the simplicity of the diagnostic process while significantly improving accuracy for users with less knowledge and experience.
