Information Provision System for Dynamic Device Design Data Disclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information provision systems face challenges in determining an appropriate disclosure range for device design data, especially when issues arise at the worksite, making it difficult for device manufacturers to pre-set the range of data provided to users.
Innovation Solution
An information provision system that manages device design data by handling elements as units, links relevance information, and generates disclosure design data by extracting designated ranges, while managing user access rights and viewable periods, enabling secure and dynamic control over data disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If device design data is provided to device users for troubleshooting, then the ability to resolve worksite issues is improved, but the risk of information leakage and loss of secrecy increases
Solution Approach 1:
The patent segments device design data into multiple granularity levels (element level, component level, assembly level, system level) and provides only the necessary segment to users based on their specific troubleshooting needs. This allows selective disclosure of information - enough to resolve the issue but not so much that overall system secrecy is compromised.
Solution Approach 2:
The patent implements local quality by applying different secrecy levels and access rights to different portions of the device design data. Each element can have its own secrecy level assigned, allowing the system to provide high-detail information locally where needed for troubleshooting while maintaining high secrecy globally for the overall system architecture.
2Ease of repair
If comprehensive device design data is provided to users, then troubleshooting effectiveness is improved, but the complexity of managing access rights and disclosure ranges increases
Solution Approach 1:
The patent implements dynamic access rights management where the disclosure range and secrecy levels are not fixed but can be adjusted in real-time based on user roles, specific troubleshooting scenarios, and organizational policies. The system dynamically determines what data to disclose based on the combination of user attributes and the nature of the troubleshooting task.
Solution Approach 2:
The patent introduces an intermediary information provision system that sits between the device design data repository and the end users. This intermediary automatically manages the complexity of access rights by interpreting user credentials, determining appropriate secrecy levels, and filtering data before presentation to users, thereby shielding users from the underlying complexity of access management.
3Reliability
If device design data is disclosed to component suppliers for performance analysis, then component quality improvement is improved, but the control over information disclosure becomes more difficult
Solution Approach 1:
The patent applies preliminary action by pre-configuring secrecy levels, access rights, and disclosure ranges for different types of users and scenarios before actual data disclosure occurs. Organizational policies and access control rules are established in advance, allowing the system to automatically enforce appropriate information control when component suppliers request data for performance analysis, without requiring ad-hoc manual approval for each request.

AI summary
An information provision system includes a design data management unit to manage device design data regarding design of a target device, including one or more items of data out of machine design data as data regarding machine design of the target device, electric design data as data regarding electric design of the target device, and control design data as data regarding control design of the target device, by handling each of a plurality of elements constituting the device design data as a unit and linking relevance information indicating relevance between elements in the plurality of elements, with each element, a design data extraction unit to generate disclosure design data by extracting a part corresponding to a designated disclosure range from the device design data in units of elements and by referring to the relevance information, and a design data issuance unit to issue the disclosure design data.
