Access Control Unit for Multi-Communication Data Storage Collision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As access to data storage locations, such as IC chips adaptable to NFC, increases, communication collisions occur, potentially leading to service failures or delays, impacting user convenience and service provision.
Innovation Solution
An information processing device with an access control unit that sets a priority order for access requests across various communications, including wired and wireless communications, to manage and reduce collisions by mediating access requests and determining the order of data retrieval based on priority.

Engineering Contradiction Analysis
1Productivity
If multiple communications access the data storage location simultaneously, then communication efficiency and service capability are improved, but access collisions occur more frequently
Solution Approach 1:
An access control unit is introduced as an intermediary between multiple communication interfaces and the data storage location. This mediator receives access requests from various communications (wired and wireless), manages their priority ordering, and controls the timing of access to the data storage location, thereby preventing collisions while maintaining efficient service delivery.
Solution Approach 2:
The access control unit performs preliminary actions by receiving and queuing access requests before they reach the data storage location. By pre-managing the order and timing of access requests, the system prevents collision conditions from arising in the first place, ensuring reliable data storage access despite multiple simultaneous communication attempts.
2Reliability
If access control management is implemented, then access collision is reduced, but system complexity increases
Solution Approach 1:
The access control unit is designed with multi-functionality, serving as a universal management component that handles access requests from multiple different communication types (wired and wireless interfaces). By consolidating access management functions in a single multi-capable unit rather than implementing separate control mechanisms for each communication type, the system reduces overall complexity while maintaining reliable collision prevention.
