Data Exchange System Valuation Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data exchange systems fail to effectively prevent the illicit duplication of valuable data during transmission between apparatuses, particularly when power supply interruptions occur, leading to potential data loss and duplication issues.
Innovation Solution
A data exchange system that determines the relative valuableness of data between two apparatuses and prioritizes the transmission and storage of more valuable data, using nonvolatile storage and temporary exchange processing to ensure that the more valuable data is securely fixed and stored, even in the event of power interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data exchange is performed between apparatuses, then data sharing and collaboration are enabled, but the risk of illicit duplication of valuable data increases
Solution Approach 1:
The system performs preliminary valuation assessment of data before exchange occurs. The determination portion evaluates the degree of valuableness of data to be exchanged in advance, establishing a hierarchy that guides the exchange protocol. This preliminary action enables the system to prepare appropriate security measures before actual data transmission, preventing illicit duplication by having control mechanisms ready ahead of time.
Solution Approach 2:
The system introduces an intermediary control mechanism that mediates the data exchange process. The determination portion acts as an intermediary that assesses data valuableness and directs the exchange protocol accordingly. This intermediary layer separates the raw data transmission from the security control, allowing the system to manage valuable data exchanges through controlled intermediaries rather than direct peer-to-peer transfer.
2Reliability
If data transmission is interrupted by power supply failure, then data loss is prevented through nonvolatile storage, but the exchange process takes longer and creates more vulnerability window
Solution Approach 1:
The system rushes through the critical data transmission phase by prioritizing valuable data exchange and using nonvolatile storage for immediate persistence. Once data is safely stored in nonvolatile memory, the system quickly progresses to the fixing phase where exchange results are confirmed. This skipping approach minimizes the vulnerable time window by rapidly completing the critical path from transmission to secure storage.
Solution Approach 2:
The system performs preliminary valuation of data to determine which data requires priority protection during exchange. By pre-identifying valuable data, the system can allocate resources and apply security measures more efficiently, reducing the overall time required for secure exchange while maintaining comprehensive protection.
3Reliability
If the system determines valuableness and prioritizes valuable data, then illicit duplication is reduced, but the processing complexity increases
Solution Approach 1:
The system segments the data exchange process into distinct functional portions: a determination portion for valuableness assessment, temporary exchange processing portions for data transfer, and fixing processing portions for result confirmation. This segmentation allows each component to specialize in its function, reducing overall complexity despite the sophisticated valuation and prioritization logic required.
Solution Approach 2:
The determination portion serves multiple functions: it evaluates data valuableness, directs the exchange protocol, and informs security措施的 selection. This multi-functionality reduces the need for separate specialized components, thereby managing system complexity while maintaining comprehensive protection against illicit duplication.

AI summary
A non-limiting example communication game system comprises at least two game apparatuses, and the two game apparatuses communicate with each other directly or via an internet according to instructions of a player. At this time, one of the two game apparatuses functions as a parent apparatus and the other of the two game apparatuses functions as a child apparatus. If both players instruct to exchange characters, character data are sent and received between the parent apparatus and the child apparatus. When a rarity of a character X that is to be sent on exchange is lower than a rarity of a character Y that is to be received by exchange, the parent apparatus receives a notification of writing start from the child apparatus, and performs save writing. On the other hand, when a rarity of a character X that is to be sent on exchange is higher than a rarity of a character Y that is to be received by exchange, the parent apparatus transmits a notification of writing start to the child apparatus, and performs save writing.
