Solution Overview

Problem

Traditional SIM provisioning for wireless communication devices requires manual entry of a lengthy embedded universal integrated circuit card identifier (EID), which is burdensome and prone to errors for users.

Innovation Solution

Implementing a user-friendly wireless service activation procedure using a friendly-phrase EID (fpEID) that allows users to request and assign a shorter, easier-to-enter identifier, enabling remote eSIM provisioning without manual EID entry, by interacting with a device vendor network and service provider network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual entry of EID is required for SIM provisioning, then service activation can be completed, but user burden increases and errors become more frequent

Engineering Contradiction:

Improveservice activation accuracyVSAvoiduser input difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs automatic EID retrieval and provisioning without requiring user input. The service activation application automatically communicates with the device vendor network to obtain the EID and completes the provisioning process, eliminating manual entry while maintaining service activation capability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The service activation application acts as an intermediary between the user and the device vendor network. It automatically manages the EID retrieval process by sending requests to the device vendor network and processing the responses, shielding users from complex technical operations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If remote eSIM provisioning is implemented, then physical device access is no longer needed, but complex identifier entry is still required

Engineering Contradiction:

Improveremote provisioning capabilityVSAvoididentifier entry complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically retrieves the EID through remote communication between the service activation application and the device vendor network, eliminating the need for users to manually enter complex identifiers while maintaining remote provisioning capability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The EID retrieval process is extracted from the user's responsibilities and transferred to the service activation application. The application automatically obtains the EID from the device vendor network, removing the burden of complex identifier entry from users

Inventive Principle:

Principle #2Taking out (Extraction)
