Equipment Element Maintenance Management via Operation History Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maintenance management systems for manufacturing equipment elements, such as component mounters, lack efficient methods for systematically controlling repair and inspection of equipment elements, leading to potential operation errors due to wear and distortion over time.
Innovation Solution
An equipment element maintenance management system that includes a history information acquirer, analyzer, maintenance result creator, and repair instruction creator to analyze operation history, perform maintenance operations, and issue repair instructions based on the equipment element's state, ensuring efficient management and repair of deteriorating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If maintenance operations are performed based on fixed service timing, then equipment elements can be maintained regularly, but maintenance efficiency is low and operation errors may still occur due to wear and distortion
Solution Approach 1:
The system performs preliminary analysis of operation history information to predict equipment element state deterioration before actual failures occur. The analyzer evaluates past operation data to identify elements that will deteriorate, enabling proactive maintenance scheduling that prevents operation errors while optimizing maintenance timing.
Solution Approach 2:
The system establishes a feedback loop where operation history information is continuously acquired, analyzed for state tendency, and used to create maintenance result information. This feedback mechanism enables dynamic adjustment of maintenance timing based on actual equipment condition trends rather than fixed schedules, improving both reliability and time efficiency.
2Reliability
If all equipment elements are transported to service center for inspection, then centralized management is achieved, but transportation cost and time increase
Solution Approach 1:
The system extracts only the equipment elements that require maintenance from the entire fleet by analyzing operation history information and identifying elements with deteriorating state trends. Instead of transporting all elements for inspection, only those with predicted deterioration are selected and transported to the service center, reducing transportation time and costs while maintaining inspection quality for elements that need it.
Solution Approach 2:
The system applies different maintenance management approaches to different equipment elements based on their individual operation history and state tendency. Elements showing deterioration trends receive centralized service center inspection, while elements with stable performance can remain at local facilities, enabling differentiated quality management that optimizes both reliability and resource utilization.
3Productivity
If operation history information is analyzed for each equipment element, then maintenance timing can be optimized, but system complexity increases
Solution Approach 1:
The system employs a universal analyzer that processes operation history information from multiple equipment elements using the same analysis methodology. The analyzer creates maintenance result information for each element by evaluating their respective operation histories, enabling standardized maintenance optimization across the entire equipment fleet without requiring separate complex systems for each element.

AI summary
An equipment element maintenance management method for managing a maintenance operation for an equipment element that is attached to manufacturing equipment for manufacturing a product includes: acquiring operation history information of the manufacturing equipment at a predetermined timing; analyzing a tendency of a state of the equipment element based on the acquired operation history information; performing the maintenance operation for the equipment element of which the state is worse than a predetermined state; creating maintenance result information which is a result of the maintenance operation; and creating a repair operation instruction for performing an instruction of a repair operation for the equipment element of which the state after the maintenance operation is not more improved than the predetermined state based on the maintenance result information.
