Solution Overview
Problem
Existing methods for determining the state of mechanical components, particularly those with moving parts, are inefficient in assessing dimensional accuracy, lubrication quality, and material deviations, often relying on mechanical measurements and maintenance schedules based on operating hours or distance, which can miss early signs of damage or lubrication issues.
Innovation Solution
A device and method using electrical voltage measurements to assess the condition of mechanical components, where changes in voltage over time provide information on dimensional accuracy, lubrication status, and material quality, employing a voltmeter and microprocessor-based evaluation to output status information through visual or auditory signals, and utilizing multivariate statistical analysis to analyze voltage curves.

1Measurement precision
If mechanical measuring methods are used to determine the condition of mechanical components, then measurements and distances can be determined using appropriate measuring methods, but the method is inefficient in assessing dimensional accuracy, lubrication quality, and material deviations
Solution Approach 1:
The patent replaces mechanical measuring methods with electrical measurement methods. A voltage source applies voltage to the motor shaft, and a measuring device (voltmeter) determines voltage or voltage changes at the mechanical component. This substitution enables more efficient and precise assessment of dimensional accuracy, lubrication quality, and material deviations through electrical quantity measurements rather than mechanical measurements.
2Reliability
If maintenance schedules based on operating hours or distance are used, then maintenance can be planned, but early signs of damage or lubrication issues can be missed
Solution Approach 1:
The patent implements continuous monitoring with feedback by measuring voltage or voltage changes at the mechanical component during operation. The measuring device is connected to an evaluation unit that processes the measurement results and outputs status information about the component's condition. This real-time feedback system enables early detection of damage and lubrication issues, allowing maintenance to be triggered by actual component condition rather than predetermined schedules.
3Reliability
If electrical voltage measurements are used to assess mechanical component condition, then early detection of mechanical damage, lubrication issues, and material deviations is enabled, but additional measurement and evaluation equipment is required
Solution Approach 1:
The patent employs a multi-functional measurement system where voltage measurements serve multiple purposes: assessing dimensional accuracy, evaluating lubrication quality, and detecting material deviations. The same voltage source and measuring device configuration enables comprehensive condition assessment across different component aspects, reducing the need for separate specialized measurement systems for each assessment type.
