Equipment Management Gateway Segmentation for Know-How Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment management systems face challenges in balancing user convenience with the need to protect sensitive information, particularly know-how, by controlling access to different types of equipment data within the system.
Innovation Solution
The system employs a gateway apparatus with an interface for operation commands, a first database for accessible information, and a second database for protected information, with a controller managing access to ensure that only authorized entities can access sensitive equipment information, thereby preventing unauthorized leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gateway apparatus is allowed to access all equipment information, then user convenience is improved, but the risk of know-how leakage increases
Solution Approach 1:
The patent divides equipment information into two distinct databases: a first database containing basic information (installation date, durable years, rated power consumption) that can be accessed by the gateway apparatus, and a second database containing maintenance information and know-how data that is prohibited from access by the gateway apparatus. This segmentation allows the system to provide user convenience for basic operations while protecting sensitive proprietary information from unauthorized access.
2Adaptability or versatility
If the gateway apparatus accesses sensitive equipment information, then operational functionality is enhanced, but information security deteriorates
Solution Approach 1:
The system segments information access rights by creating two separate databases with different access permissions. The gateway apparatus can access the first database to perform basic equipment operations, while the controller maintains exclusive access to the second database containing sensitive maintenance information. This segmentation enables the gateway to provide operational functionality without compromising information security.
Solution Approach 2:
The controller acts as an intermediary that manages access to equipment information. It selectively allows the gateway apparatus to access basic information while prohibiting access to sensitive maintenance data. The controller mediates between the gateway's need for operational access and the requirement for information security, enabling functionality while protecting proprietary know-how.
Data Source
AI summary
An equipment management system comprises a gateway apparatus having an interface configured to receive an operation command for operating an equipment, a first database configured to store first information allowed access from the gateway apparatus, a second database configured to store second information prohibited access from the gateway apparatus, and a controller configured to allow access to the first database from the gateway apparatus and prohibit access to the second database from the gateway apparatus. The second information includes equipment information collected from a control apparatus controlling the equipment.
