Single Communication Chip for Non-Contact IC Card Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of services and service providers increases, the hierarchical configuration of non-contact IC card storage areas becomes complex, leading to slower access and more cumbersome read and search processing, and the existing method of providing one communication chip per secure chip results in a more complicated device configuration and increased costs.
Innovation Solution
A communication system that uses a single communication chip to identify and select the appropriate processing portion based on identification information, allowing for non-contact communication between a first information processing device and a second information processing device, which includes a storage portion that stores correspondence information for processing portion selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hierarchical configuration of storage area is used to organize services and providers, then service management capability is improved, but access speed deteriorates and processing becomes more cumbersome
Solution Approach 1:
The patent segments the storage area into multiple management units, each handled by a dedicated processing portion. This allows parallel access to different segments, improving overall access speed while maintaining the hierarchical service management structure. The segmentation enables simultaneous operations without contention on a single processing path.
Solution Approach 2:
The patent introduces a new dimension of organization by mapping services to specific processing portions based on provider identification. This adds a lateral dimension to the hierarchical structure, allowing direct routing to appropriate processing portions and reducing the depth of hierarchical traversal, thereby improving access speed.
2Speed
If one communication chip is provided for one secure chip to simplify processing portion selection, then processing portion selection speed is improved, but device complexity increases and surface area increases
Solution Approach 1:
The patent implements a single communication chip that can communicate with multiple secure chips through a unified interface. The system uses a single communication chip with multi-functionality to select and communicate with different processing portions based on provider identification, eliminating the need for dedicated communication chips for each secure chip while maintaining fast selection capability.
Solution Approach 2:
The patent introduces a provider identification-based routing mechanism as an intermediary layer between the single communication chip and multiple secure chips. This mediator rapidly directs communication to the appropriate processing portion without requiring multiple communication chips, thus improving selection speed while controlling device complexity.
3Reliability
If one communication chip is provided for one secure chip, then communication reliability is improved, but manufacturing cost increases due to increased surface area
Solution Approach 1:
The patent merges multiple communication functions into a single communication chip that can handle communications with multiple secure chips. This consolidation reduces the total number of communication chips required, decreasing the mounted surface area and manufacturing cost while maintaining communication reliability through the unified interface and routing mechanism.
Solution Approach 2:
The single communication chip is designed with universal communication capabilities to interface with multiple secure chips and processing portions. This multi-functional design eliminates the need for multiple dedicated communication chips, reducing component count, surface area, and manufacturing cost while preserving reliable communication through standardized protocols and routing.

AI summary
A communication system includes a first information processing device, a plurality of processing portions, a storage portion, and a second information processing device. The first information processing device includes a processing command transmission portion that transmits to the second information processing device, by non-contact communication, a processing command that includes one of a plurality of identification information items. Each of the processing portions is uniquely associated with one of the identification information items. The storage portion stores a correspondence information item that indicates a correspondence between one of the identification information items and one of the processing portions. The second information processing device includes a processing portion selection portion that selects one of the processing portions to execute the processing command received from the first information processing device, based on the correspondence information item stored in the storage portion and on the identification information item included in the processing command.
