Solution Overview

Problem

Existing eSIM card detection methods in terminal devices often lead to inefficient and inconvenient startup settings due to the lack of detection of actual eSIM card presence, causing users to repeatedly add eSIM cards despite their presence, which affects user experience.

Innovation Solution

A method for detecting embedded subscriber identity module (eSIM) cards in terminal devices that involves receiving user input during startup, checking for eSIM card configuration information, and providing tailored out-of-box experience interfaces based on the detection results, including powering on the eSIM card if necessary to ensure accurate and efficient setup guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the terminal device provides eSIM card addition guidance during first startup after reset regardless of whether eSIM card is already present, then the device can guide users to add eSIM card, but users will repeatedly add eSIM card unnecessarily causing inefficient and inconvenient startup setting

Engineering Contradiction:
Improvestartup setting convenienceVSAvoidrepeated eSIM card addition time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The terminal device performs preliminary detection of eSIM card presence and configuration information before providing startup guidance. The device checks whether eSIM card is detected and whether configuration information exists in memory, then provides differentiated guidance based on the detection results, avoiding unnecessary repeated addition operations by users

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanism by detecting eSIM card presence and configuration information status, then using this feedback to dynamically adjust the startup guidance provided to users. When eSIM card and configuration information are detected, the system provides different guidance compared to when they are not present, preventing unnecessary repeated operations

Inventive Principle:
Principle #23Feedback

2Productivity

If the terminal device detects eSIM card configuration information and provides differentiated startup guidance, then startup setting efficiency is improved, but device complexity increases due to detection and conditional logic

Engineering Contradiction:
Improvestartup setting efficiencyVSAvoiddetection and control logic complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The terminal device performs preliminary detection of eSIM card presence and configuration information during first startup after reset. By detecting whether eSIM card is present and whether configuration information exists in memory before providing guidance, the system enables efficient differentiated startup settings while using simple detection logic that does not significantly increase device complexity

Inventive Principle:
Principle #10Preliminary action

AI summary

This application belongs to the technical field of terminals, and provides a method for detecting an embedded subscriber identity module eSIM card and a terminal device. The method includes: receiving a first operation inputted by a user during first startup setting after a terminal device is reset; detecting, in response to the first operation, whether eSIM card configuration information currently exists in the terminal device; and displaying a first out-of-box experience interface when the eSIM card configuration information exists, where the first out-of-box experience interface includes first prompt information, and the first prompt information is used for prompting to set an eSIM card corresponding to the eSIM card configuration information. The terminal device detects the eSIM card configuration information, and provides a setting guidance corresponding to an actual existence state of the eSIM card for a user based on a detection result of the eSIM card configuration information, which can solve a problem of inefficient and inconvenient eSIM card setting.
