Solution Overview

Problem

Existing systems require manual intervention to disable specific functions on IC cards, leading to a significant management burden for users and administrators.

Innovation Solution

A portable electronic device, such as an IC card, equipped with a processor that automatically disables a specific function based on date data analysis, eliminating the need for manual commands by executing a disabling process when predetermined conditions are met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a disabling command is explicitly transmitted to disable a specific function of an IC card, then the function can be disabled during operation, but management burden on users or administrators becomes large

Engineering Contradiction:
Improveautomatic function disablingVSAvoidmanagement burden
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The IC card automatically disables specific functions by itself based on date data comparison, without requiring external disabling commands from users or administrators. The card's processor compares first date data (current date) with second date data (reference date) and autonomously executes the disabling process when the reference date is reached, making the system self-managing and eliminating manual intervention.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If manual intervention is required to disable functions on IC cards, then precise control over function disabling is achieved, but significant management burden is imposed on users and administrators

Engineering Contradiction:
Improvemanagement burdenVSAvoidcontrol mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The reference date (second date data) is predetermined and stored in the IC card before operation. This preliminary setup allows the card to automatically trigger the disabling process at the appropriate time without requiring complex real-time control mechanisms or manual intervention during operation, thereby reducing management burden while maintaining precise control timing.

Inventive Principle:
Principle #10Preliminary action

3Extent of automation

If a disabling command is transmitted to disable a specific function, then the command structure remains simple, but the process requires explicit external transmission and processing

Engineering Contradiction:
Improveautomatic disabling processVSAvoidtime for command transmission and processing
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The date comparison function and the disabling execution function are merged into a single integrated process within the IC card. When the processor compares the first date data with the second date data and determines that the reference date has been reached, it directly executes the disabling process in the same operational cycle, eliminating the need for separate command transmission and processing steps, thereby reducing time loss.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A portable electronic device according to an embodiment includes a processor that executes a first process according to a command received from an external device. The processor determines whether a disabling condition is satisfied by using command reception as a trigger, executes a disabling process of disabling a predetermined function of a second process different from the first process and then executes the first process when the disabling condition is satisfied, and executes the first process without executing the disabling process when first date data does not exceed second date data.
