Smart Assistance Device for Equipment Maintenance Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex equipment systems require precise diagnostic and maintenance operations, which are often prone to errors due to reliance on checklists and manuals, and existing smart assistance devices are limited in tracking all steps, dependent on user intervention, and not universally applicable.
Innovation Solution
A smart assistance device that receives image frames from an imaging device, detects equipment parts, tags them, and compares reverse steps to forward steps to detect discrepancies, providing real-time notifications and recommendations to correct errors, and optimizes assembly line processes by simulating digital assembly models to minimize changeover time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If checklists and manuals are used to track diagnostic operations, then all steps of operations can be documented, but operational errors still occur due to operator dependency
Solution Approach 1:
The system enables self-service by automatically capturing images during maintenance operations and comparing them against reference images to detect discrepancies. The system serves itself by autonomously identifying operational errors without requiring continuous operator intervention or manual verification, thus reducing operator dependency while maintaining high reliability
Solution Approach 2:
The system implements feedback by capturing real-time images during maintenance operations, automatically comparing them with reference images, and providing immediate feedback on discrepancies. This closed-loop feedback mechanism ensures that operational errors are detected and highlighted without relying on operator memory or manual checking, thereby reducing errors while maintaining automation
2Productivity
If skilled workforce performs complex operations, then operations can be performed efficiently, but errors may still be made under pressure
Solution Approach 1:
The system provides real-time feedback by capturing images during operations and immediately comparing them against reference images to detect discrepancies. This feedback mechanism assists skilled operators in maintaining high efficiency while reducing errors by providing objective verification of their work, thus improving both productivity and reliability
Solution Approach 2:
The system substitutes manual visual inspection with automated image recognition and comparison. Instead of relying solely on human judgment, the system uses automated image processing to detect discrepancies, thereby reducing human error while maintaining the efficiency of skilled operators
3Measurement precision
If image capture and comparison is performed for all steps, then operational accuracy is improved, but time consumption increases
Solution Approach 1:
The system applies partial action by capturing images only at critical steps where discrepancies are most likely to occur, rather than continuously capturing images throughout all operations. This selective imaging approach maintains high operational accuracy for critical operations while reducing overall time consumption for image processing

AI summary
A method and system of providing assistance during an operation performed on an equipment by a smart assistance device. A first set of image frames and a second set of image frames corresponding to forward steps and reverse steps respectively performed during the operation are received from an imaging device. Parts of the equipment are detected in each of first set of image frames and tagged. The smart assistance device detects parts of the equipment present in an image frame for each of the second set of the image frames. A discrepancy is determined in the reverse steps by comparing the parts of the equipment present in the frame of the second set of the image frames with the parts tagged in the corresponding first image frame of the first set of image frames. A notification and recommendation is provided to correct the discrepancy.
