Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shaft misalignment in rotating equipment often goes undetected until damage occurs, leading to vibrations, excessive stress, and premature failure, as existing detection methods are not real-time and require shutdown for assessment.
Innovation Solution
A system utilizing planetary gear sets with integrated laser sources and receivers to continuously monitor shaft alignment during operation, emitting and receiving a laser beam to detect misalignment and transmit data to a computer processor for real-time analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration analysis, thermography, or vibration phase readings are used to detect shaft misalignment, then misalignment can be detected, but detection occurs only after damage has occurred or equipment fails, requiring shutdown for assessment
Solution Approach 1:
The system performs preliminary detection of shaft misalignment continuously during operation, identifying alignment issues before they cause damage or failure. The laser-based measurement system continuously monitors shaft position, enabling early warning and preventive action rather than waiting for failure indicators to appear.
Solution Approach 2:
The patent replaces traditional mechanical measurement tools (straightedge rulers, dial indicators, laser guides) that require shutdown with a non-contact optical measurement system using lasers. This substitution enables continuous monitoring during operation, eliminating the need to stop equipment for alignment checks.
2Ease of repair
If traditional alignment tools such as straightedge rulers, dial indicators, or laser guides are used, then shaft re-alignment can be performed, but the equipment must be shut down and components checked preliminarily
Solution Approach 1:
The system replaces contact-based mechanical alignment tools with a non-contact optical laser measurement system. This enables alignment monitoring and measurement to occur during continuous operation without requiring equipment shutdown, maintaining productivity while providing alignment capability.
Solution Approach 2:
The alignment monitoring system operates continuously during equipment operation, providing uninterrupted measurement and detection capabilities. The useful action of alignment monitoring continues without interruption, eliminating the need to stop production for assessment or realignment work.
3Reliability
If continuous real-time monitoring of shaft alignment is implemented, then damage can be prevented by detecting misalignment early, but the system complexity increases with planetary gear apparatus and laser components
Solution Approach 1:
The patent introduces planetary gear apparatus as an intermediary mechanism that converts high-speed shaft rotation into lower-speed ring gear rotation. This intermediary enables the laser measurement system to track alignment changes at a manageable rate while maintaining continuous monitoring of the high-speed shaft, balancing reliability with practical system implementation.
Solution Approach 2:
The system replaces complex mechanical alignment measurement procedures with an optical laser measurement system. This substitution simplifies the overall approach by using non-contact optical fields instead of complex mechanical gauges and measurement procedures, reducing operational complexity despite the added optical components.
