Terminal Schedule Management via Local Time Zone Adaptation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional portable terminals fail to manage schedule information effectively when local time changes, leading to missed or repeatedly executed schedules due to changes in reference time zones.

Innovation Solution

A method and apparatus for managing schedules based on local time changes, which determine if the local time shifts to an earlier or later time zone, preventing re-execution of already processed schedules and reporting unprocessed information to the user, utilizing a storage device and controller within the terminal to recognize and adjust schedule execution accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the reference time is changed to adapt to local time zone changes, then the terminal can operate in different time zones, but schedule information may be repeatedly executed or missed

Engineering Contradiction:

Improvetime zone adaptabilityVSAvoidschedule execution accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by checking whether a schedule has already been executed before executing it again after a time zone change. The controller stores execution status information and performs a preliminary check to determine if the schedule condition has already been met, preventing repeated execution when the time is adjusted forward. This proactive verification mechanism ensures schedule reliability while maintaining time zone adaptability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by continuously monitoring the execution status of schedules and comparing it with the current time and time zone settings. When a time zone change occurs, the system feedbacks on which schedules have already been executed and adjusts the execution logic accordingly, notifying users of missed schedules and preventing re-execution of completed schedules. This closed-loop feedback mechanism resolves the contradiction between adaptability and reliability.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the local time is adjusted forward to a later time zone, then the terminal operates with updated time, but schedule information during the skipped period is missed

Engineering Contradiction:

Improvetime zone adjustment capabilityVSAvoidmissed schedule information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by proactively identifying and notifying users about schedules that would have been executed during the skipped time period before the time zone change is fully applied. The controller calculates which schedules fall within the skipped period and provides advance notification, allowing users to take appropriate action. This prevents complete loss of schedule information while maintaining time zone adaptability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by notifying users about missed schedules after a time zone adjustment. The system provides feedback information about which schedules were not executed due to the time skip, enabling users to manually handle these missed schedules. This feedback mechanism reduces information loss while preserving the ability to adjust time zones freely.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the local time is adjusted backward to an earlier time zone, then the terminal operates with updated time, but already executed schedule information is processed again

Engineering Contradiction:

Improvetime zone adjustment capabilityVSAvoidrepeated schedule execution

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by performing a pre-execution check to determine whether a schedule has already been executed before allowing re-execution after a backward time zone adjustment. The controller stores and retrieves execution status information, and only permits schedule execution if the preliminary check confirms it has not been executed yet. This prevents harmful repeated execution while maintaining time zone adaptability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by monitoring and tracking the execution status of schedules across time zone changes. When the time is adjusted backward, the system feedbacks on which schedules have already been executed and blocks their re-execution. This feedback mechanism eliminates the harmful effect of repeated schedule execution while preserving the ability to adjust time zones as needed.

Inventive Principle:

Principle #23Feedback

AI summary

Provided is a method and apparatus for managing a schedule of a terminal based on a local time. It is possible to prevent schedule information from a schedule of a terminal from being repeatedly processed or from being missed, when the local time changes due to the movement of the terminal into another time zone or due to daylight saving time. It is also possible to manage a schedule by determining if the schedule has changed during a period between a time before the change and the changed time.
