Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The spread of remote SIM provisioning (RSP) technology in communication devices leads to an increase in temporary wireless communication profiles, causing inconvenience due to the storage of unnecessary profiles in devices.

Innovation Solution

A communication apparatus equipped with circuitry to determine if an end condition is met for an embedded SIM (eSIM) profile, prompting the user through a user interface to decide whether to delete the profile when the condition is satisfied.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple eSIM profiles are stored in the communication apparatus, then the adaptability and versatility of the device are improved, but the device complexity increases due to the need to manage and track usage conditions of multiple profiles

Engineering Contradiction:

Improveprofile storage capabilityVSAvoidprofile management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically monitors usage conditions and determines when profiles should be deleted without requiring manual user intervention. The communication apparatus self-manages the profile lifecycle by detecting when usage conditions are met and prompting users for deletion confirmation, thereby reducing management complexity while maintaining multi-profile adaptability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where usage information is continuously monitored and fed back to the control unit. When usage conditions are satisfied, the system provides feedback to the user interface to prompt profile deletion, creating a closed-loop management system that reduces complexity through automated monitoring and user notification

Inventive Principle:

Principle #23Feedback

2Ease of operation

If automatic profile deletion is implemented, then the ease of operation is improved, but the reliability may be affected due to potential loss of profiles that users might want to retain

Engineering Contradiction:

Improveprofile deletion convenienceVSAvoidprofile retention reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by monitoring and detecting when usage conditions are met before actual profile deletion occurs. The system prepares deletion candidates and presents them to users in advance, allowing users to review and confirm deletion decisions, thereby maintaining reliability while improving ease of operation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a confirmation mechanism that acts as a preliminary counter-action to automatic deletion. Before profiles are deleted, the system prompts users for confirmation, allowing users to prevent deletion if they wish to retain the profile. This preliminary anti-action protects against unintended profile loss while maintaining the automated management benefits

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A communication apparatus comprises circuitry configured to determine whether an end condition is satisfied, the end condition relating to an embedded subscriber identity module (eSIM) profile stored in a memory; and in a case that the end condition is satisfied, control display of an output via a user interface, the output requesting instruction whether or not to delete the eSIM profile.
