Communication Apparatus Automatic Re-Transfer to Intended Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices, such as digital cameras, may inadvertently transfer data to an unintended external apparatus after a transfer failure, as they automatically re-transfer images to any connected FTP server, which is not necessarily the original intended server.
Innovation Solution
A communication apparatus with a storage unit to store transfer failure information associating data items with intended transfer destinations, and a transfer control unit to automatically re-transfer data items to the correct external apparatus upon reconnection, ensuring data is transferred to the intended server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic re-transfer mechanism is implemented, then transfer reliability is improved, but data may be transferred to unintended external apparatus
Solution Approach 1:
The system performs preliminary action by storing the association relationship between data items and their intended transfer destinations before the transfer occurs. When re-transfer is needed, this pre-stored information guides the system to correctly identify and transfer data to the intended destination, preventing unintended transfers while maintaining automatic re-transfer functionality.
Solution Approach 2:
The system implements feedback by recording the association relationship between data items and transfer destinations during the initial transfer process. This feedback information is then utilized during re-transfer operations to ensure data is sent to the correct destination, resolving the contradiction between automatic re-transfer and preventing unintended transfers.
2Ease of operation
If simple automatic re-transfer is used, then ease of operation is improved, but transfer precision is worsened
Solution Approach 1:
The system performs preliminary action by pre-storing the association relationship between data items and their intended transfer destinations. This allows the system to maintain simple automatic re-transfer operation while achieving precise data transfer to the correct destination, as the association information is already prepared in advance.
Solution Approach 2:
The system creates a copy of the association relationship information (mapping data items to their intended destinations) and uses this copy during re-transfer operations. This copying approach enables precise transfer decisions without complicating the user operation, as the system automatically uses the pre-copied association data to guide re-transfer processes.
Data Source
AI summary
There is provided a communication apparatus. A communication control controls a communication unit so as to connect to one of a plurality of external apparatuses. A transfer unit transfers a data item to an external apparatus to which the communication unit has connected. In a case that a transfer of the data item is failed, a storage control unit stores transfer failure information in which the data item is associated with a transfer-destination external apparatus. In a case that the communication unit has connected to a first external apparatus, a transfer control unit controls a transfer of a data item. If a data item included in the transfer failure information is associated with the first external apparatus, the transfer control unit performs control so as to automatically transfer the data item to the first external apparatus.
