Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire rope inspection systems face difficulties in aligning waveforms between measurement data when information on the position of the wire rope cannot be obtained from the elevator, making it challenging to perform inspections effectively.
Innovation Solution
A wire rope inspection system equipped with a detection coil to detect changes in the magnetic field of the wire rope and a control unit that extracts and aligns the inspection operation start points from first and second measurement data, ensuring that the start points coincide, allowing for easy alignment of waveforms even without position information from the elevator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If waveform alignment is performed using position information from the elevator, then alignment accuracy is improved, but the system becomes dependent on external position data that may not be available
Solution Approach 1:
The inspection operation start point serves as an intermediary reference marker extracted from the measurement data itself. Instead of relying on external position information from the elevator, the system identifies characteristic points (start points of inspection operations) within the measurement data and uses these as alignment references. This mediator enables waveform alignment while maintaining system independence from external position data sources.
2Measurement precision
If external position information from the elevator is used for waveform alignment, then alignment precision is improved, but the device complexity increases due to additional data acquisition requirements
Solution Approach 1:
The measurement data itself provides the reference information needed for alignment through self-service. The inspection operation start points, which are inherently present in the measurement data, are extracted and used as alignment references. This eliminates the need for separate position information acquisition systems, reducing device complexity while maintaining alignment precision.
3Device complexity
If waveform alignment is performed without position information, then system simplicity is improved, but the ability to accurately align waveforms deteriorates
Solution Approach 1:
The essential alignment reference information is extracted directly from the measurement data by identifying inspection operation start points. This extraction process isolates the critical timing markers needed for alignment without requiring the entire complex position information system. The extracted start points provide sufficient precision for waveform alignment while maintaining system simplicity.
