Information Management Re-Request Control for Missing Summary Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image management cloud services face failures in generating summary information and other operations, leading to inefficiencies and potential data loss.
Innovation Solution
An information management apparatus with a request unit, deletion unit, and re-request control unit to manage data, handle response failures, and re-request summary information generation based on the type of response and data presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system automatically retries summary information generation after data deletion, then summary information reliability is improved, but unnecessary re-requests are generated causing system inefficiency
Solution Approach 1:
The system performs preliminary action by checking data presence before initiating summary information generation. The determination unit checks whether the image is present in the storage unit before the request unit generates a re-request, preventing unnecessary operations in advance
Solution Approach 2:
The system implements feedback by using the response from the summary information generation apparatus to determine subsequent actions. The determination unit analyzes the response type and combines it with data presence information to decide whether to retry, creating a closed-loop control system
2Productivity
If the system checks data presence before re-requesting summary information, then unnecessary re-requests are reduced, but system complexity increases
Solution Approach 1:
The system segments the re-request control process into distinct functional units: the response reception unit receives the response, the determination unit checks data presence and decides whether to retry, and the request unit executes the re-request. This modular segmentation simplifies the overall control logic
Solution Approach 2:
The determination unit acts as an intermediary between the response reception unit and the request unit. It receives the response type information, checks data presence, and based on this intermediate determination, controls whether the request unit should generate a re-request
3Reliability
If the system makes re-requests for all failure responses, then summary information completion is improved, but data loss increases when data is already deleted
Solution Approach 1:
The system performs preliminary verification by checking whether the image data is present in the storage unit before attempting to generate summary information. This preliminary action prevents information loss by avoiding operations on already-deleted data
Solution Approach 2:
The system uses feedback from both the response type and the data presence check to control re-request behavior. When the response indicates failure to obtain data and the data is confirmed absent, the system cancels the re-request, preventing unnecessary operations and information loss

AI summary
An information management apparatus manages data and includes a request unit to make a request to generate summary information of the data to a summary generation apparatus, a deletion unit to delete the data, and a re-request control unit to control whether to make a re-request to generate the summary information of the data to the summary generation apparatus, depending on a type of a response to the request and whether the data is present. The re-request control unit performs control to make the re-request in a case where the type of the response is a failure to obtain the data by the summary generation apparatus and the data is present, and performs control to cancel the re-request in a case where the data is not present even though the type of the response is the failure to obtain the data by the summary generation apparatus.
