Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operational burden on operators in factories with numerous machines is increasing due to robotization, downsizing, and diversification, exacerbated by aging operators, necessitating a technology to lighten this load.
Innovation Solution
An assistance device that stores machine information such as maintenance history, abnormality history, and predicted lifespan, accepts search conditions, and extracts relevant machine identification information for display, reducing the need for manual updates and searches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators manually investigate machine information and locate machines on site, then they can perform maintenance and inspection operations, but the operational burden increases significantly
Solution Approach 1:
The system pre-registers machine information including location data, maintenance history, and operational status in a database before operators need this information. When operators need to locate or investigate machines, the information is already prepared and can be quickly retrieved through the terminal device, eliminating the need for manual on-site investigation.
Solution Approach 2:
A management system acts as an intermediary between operators and machine information. The system includes a database storage unit that stores machine data, a communication unit that transmits information, and a terminal device that displays results. This intermediary automates the information retrieval process, replacing manual investigation with automated queries and displays.
2Productivity
If the number of machines increases due to robotization and diversification, then production capability improves, but operator workload increases
Solution Approach 1:
The management system serves multiple functions: it stores machine information, retrieves data based on search conditions, displays results on terminals, and supports various types of machines (robots, manufacturing equipment, measurement devices). This universal system handles diverse machine types through a single integrated platform, reducing the complexity of managing increasing numbers of machines.
Solution Approach 2:
The system enables operators to independently query and retrieve machine information through terminal devices without requiring manual assistance or complex procedures. Operators can input search conditions and automatically receive relevant information, allowing them to self-serve when managing the increasing number of machines.
3Measurement precision
If operators investigate various types of information to determine maintenance targets, then accurate machine selection is achieved, but the process becomes time-consuming
Solution Approach 1:
The system pre-categorizes and stores machine information including maintenance history, operational status, and location data in the database before operators need this information. When operators need to select maintenance targets, the system can quickly retrieve and filter this pre-organized information based on search conditions, providing accurate machine selection without time-consuming manual investigation.
