Solution Overview

Problem

Existing eSIM activation processes require two-stage access and are complicated, and users find it difficult to select an optimal mobile communication plan.

Innovation Solution

An eSIM activation system and program that allows one-step activation through an activation server, which provides a mobile communication plan, generates a two-dimensional barcode, and activates the eSIM upon reading by a user's terminal device, enabling easy selection of an optimal plan based on usage state and schedule.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two-stage access is used for eSIM activation (first-stage access to guidance site and second-stage access to activation site), then the activation process can be completed with proper authentication and verification, but the activation procedure becomes complicated and requires multiple steps

Engineering Contradiction:
Improveactivation verificationVSAvoidactivation procedure
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the first-stage access (guidance site) and second-stage access (activation site) into a single unified access process. The terminal device directly accesses the activation site in one step, eliminating the need to separately visit the guidance site. This combining of access stages maintains authentication reliability while significantly simplifying the user operation process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the activation process into distinct functional components that can be executed in a streamlined sequence: (1) terminal device accesses activation site directly, (2) authentication code is transmitted and verified, (3) eSIM is activated. This segmentation allows each function to be performed efficiently without redundant steps, resolving the contradiction between verification reliability and operational simplicity.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If users select eSIM package products in advance at stores or vending machines, then payment can be processed, but users find it difficult to select an optimal mobile communication plan corresponding to their usage state and schedule

Engineering Contradiction:
Improvepayment processingVSAvoidplan selection flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic plan selection system where the terminal device can access multiple communication plans from different carriers and adjust selections based on real-time user needs, usage state, and schedule. This dynamic approach allows users to optimize their plan choice after purchase rather than being locked into a pre-selected option, thereby enhancing adaptability while maintaining payment processing efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables users to independently select and adjust their communication plans through the terminal device interface without requiring store staff assistance. Users can compare different plans, evaluate them against their usage patterns, and make informed selections autonomously, thus improving both plan selection flexibility and the overall user experience.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple communication carriers are available for eSIM activation, then users have more options, but it becomes more difficult to select the optimal plan corresponding to usage state and schedule

Engineering Contradiction:
Improvecarrier optionsVSAvoidselection process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates a feedback mechanism where the terminal device analyzes user usage state and schedule information, then provides tailored recommendations for optimal communication plans among the available carriers. This feedback loop helps users navigate multiple carrier options by presenting only the most suitable plans based on their specific needs, thereby maintaining high adaptability while reducing selection complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary analysis of user usage patterns and carrier plan characteristics before presenting options to the user. By pre-evaluating which plans best match the user's usage state and schedule, the system filters out suboptimal choices in advance, making the final selection process simpler while preserving access to multiple carrier options.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided are an eSIM activation system and a program that allow a user to easily select an optimal mobile communication plan by making access for activation of an eSIM in one step. In the eSIM activation system and the program, an eSIM terminal device 2 performs an eSIM application, a user selects a mobile communication plan in correspondence with a usage state and a usage schedule and makes a payment, when an e-mail address of the user is input on a display screen of the eSIM terminal device 2, an activation server 1 transmits a URL of an activation site to a user terminal to which the e-mail address is set, a user terminal 3 accesses the activation site from the URL and inputs a one-time authentication code to display a two-dimensional barcode for installation on the user terminal 3, and when the two-dimensional barcode is read into a communication setting of the user terminal 3, activation is completed.
