Solution Overview

Problem

Existing information processing devices struggle to support multiple communication methods or standards without requiring multiple operating systems or replacing existing reader/writers, especially when communication is interrupted and resumed without re-transmitting polling commands.

Innovation Solution

An information processing device with a selection unit that identifies and selects an appropriate application based on first identification information within a processing instruction, using association information to ensure compatibility with different communication methods, and an execution unit that executes the selected application's process, allowing for seamless communication with external devices without replacing existing reader/writers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single OS is used in the information processing device, then device complexity is reduced, but adaptability to different communication methods deteriorates

Engineering Contradiction:
Improvenumber of operating systemsVSAvoidsupport for multiple communication methods
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent segments the multi-OS system into a single host OS with multiple virtual OS environments. Each virtual OS is isolated and managed independently through virtualization technology, allowing the system to support multiple communication methods while maintaining a single physical operating system infrastructure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The host OS is designed to universally support multiple communication methods by providing a virtualization layer that can instantiate different virtual OS environments. This universal platform can adapt to various communication standards (NFC, contactless IC cards, portable phones) without requiring separate physical OS installations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If existing reader/writers are not replaced, then ease of operation is maintained, but ability to handle new communication methods deteriorates

Engineering Contradiction:
Improvecompatibility with existing readers/writersVSAvoidsupport for different communication standards
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces a message structure conversion mechanism as an intermediary layer between existing reader/writers and the host OS. This converter translates messages from different communication methods into a unified format that the single OS can process, allowing legacy hardware to support new communication standards without modification.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically changes message parameters and structures based on the detected communication method. When receiving messages from different communication standards, the system adjusts its processing parameters and uses appropriate virtual OS environments to handle the varying message formats, enabling compatibility with existing readers/writers while supporting diverse communication methods.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If message structure conversion is implemented, then adaptability to different communication methods is improved, but device complexity increases

Engineering Contradiction:
Improvehandling of different message structuresVSAvoidmessage processing mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The message processing functionality is segmented into separate virtual OS environments, each specialized for handling specific communication methods. This segmentation isolates complex conversion logic within individual virtual environments, preventing complexity from propagating throughout the entire system while maintaining adaptability to different message structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates virtual copies of OS environments that replicate the behavior of different communication methods. Instead of implementing complex conversion logic in the host OS, it uses virtualized copies that naturally handle their respective message structures, reducing the complexity of the message processing mechanism while maintaining adaptability.

Inventive Principle:
Principle #26Copying
