IC Chip Data Transfer for Storage Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing terminals with non-contact communication capabilities face storage volume limitations, requiring data deletion and re-registration when storage is full, which burdens users and reduces convenience.
Innovation Solution
An information processing terminal with an IC chip that includes a first storage portion for data used by the IC chip, a second storage portion outside the IC chip, and a data transfer portion that allows user-inputted selective allocation of data between these storage portions, enabling flexible data management without the need for re-registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored in the storage portion of the IC chip, then non-contact communication with reader/writer is enabled, but storage volume is limited causing data deletion and re-registration requirements
Solution Approach 1:
The storage function is segmented into two distinct parts: a first storage portion within the IC chip for data accessible to reader/writer, and a second storage portion outside the IC chip for additional data storage. This segmentation allows the system to overcome the storage volume limitation of the IC chip while maintaining its non-contact communication capabilities.
Solution Approach 2:
The data transfer portion acts as an intermediary mechanism that enables selective transfer of data between the first storage portion (within IC chip) and the second storage portion (outside IC chip). This intermediary allows flexible data management and expansion beyond the IC chip's storage limits.
2Quantity of substance
If storage portion is filled with data, then storage capacity is maximized, but data deletion is required to make space for new data
Solution Approach 1:
By segmenting storage into two portions, the system can store data in the second storage portion without affecting the first storage portion's capacity. This eliminates the need to delete existing data to make space for new data, as the second storage portion can accommodate additional data without impacting the IC chip's storage.
Solution Approach 2:
The system provides dynamic data management capability through the data transfer portion, allowing users to selectively transfer data between storage portions based on needs. This dynamic flexibility eliminates the rigid requirement to delete data when full, enabling more convenient data management operations.
3Quantity of substance
If data is deleted to make space, then storage space is created, but re-registration process is required which burdens the user
Solution Approach 1:
The data transfer portion serves as an intermediary that enables direct data transfer between storage portions without requiring re-registration processes. Users can selectively transfer data from the first storage portion to the second storage portion through this intermediary mechanism, eliminating the burdensome re-registration steps required in conventional systems.
Solution Approach 2:
The system is pre-configured with a data transfer mechanism that automatically handles data relocation when storage space is needed. This preliminary setup eliminates the need for users to perform complex re-registration operations, as the data transfer portion can handle the relocation process smoothly and automatically.

AI summary
There is provided an information processing terminal that is provided with an IC chip that is capable of non-contact communication with a reader/writer. The information processing terminal includes a first storage portion, a second storage portion, and a data transfer portion. The first storage portion is provided within the IC chip and is capable of storing at least one type of data item that is used by the IC chip. The second storage portion is disposed outside the IC chip. The data transfer portion transfers the data item between the first storage portion and the second storage portion in accordance with a user input.
