Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional maintenance information output apparatuses for speed reducers in industrial robots fail to consider factors other than torque, rotations, and operation time, leading to inadequate maintenance information and incorrect inspection or replacement needs.
Innovation Solution
A maintenance information output system that includes an iron amount detecting device to measure the iron in the lubricant of the speed reducer, with a controlling portion that outputs maintenance information when the iron level exceeds a threshold value, allowing for stepwise maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If maintenance information is based only on torque, rotations, and operation time, then the system is simple to operate, but the maintenance information accuracy deteriorates
Solution Approach 1:
The patent introduces an iron amount detecting device as an intermediary component that measures iron particles in the lubricant. This mediator provides direct evidence of actual wear conditions, bridging the gap between simple operation and accurate maintenance information. The iron particle measurement serves as an objective indicator of speed reducer health, supplementing the basic operational parameters without complicating the system architecture.
2Device complexity
If conventional parameters (torque, rotations, operation time) are used, then the device complexity is low, but the reliability of maintenance information deteriorates
Solution Approach 1:
The patent replaces reliance on calculated mechanical parameters (torque, rotations, time) with direct physical measurement of iron particles in the lubricant. This substitution uses actual wear debris detection instead of inferred mechanical stress indicators, significantly improving the reliability of maintenance information while adding only one detection component to the system.
3Measurement precision
If iron amount detection is added, then the maintenance information accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the critical diagnostic function from the complex system of multiple operational parameters and isolates it into a single iron amount detecting device. By focusing on measuring only iron particles in the lubricant, the system extracts the essential wear information needed for accurate maintenance decisions, avoiding the complexity of monitoring and analyzing multiple simultaneous parameters.

Data Source
AI summary
A maintenance information output system is provided that includes an iron amount detecting device, a receiver, a maintenance information output apparatus, and a controlling portion. The iron amount detecting device is attached to a speed reducer, and detects an amount of iron in a lubricant in the speed reducer. The receiver receives data of the amount of iron detected by the iron amount detecting device. The maintenance information output apparatus has an outputting portion which outputs maintenance information of the speed reducer. The maintenance information output apparatus has a receiving portion which receives the data from the receiver. When the amount of iron is equal to or larger than a threshold value, the controlling portion causes the outputting portion to output the maintenance information.
