Solution Overview

Problem

Mobile devices with eSIMs are limited to a single Mobile Network Operator (MNO) configuration, leading to inefficient utilization of wireless services, as all software applications share the same connectivity, often resulting in excessive or insufficient usage.

Innovation Solution

Implementing a collection of electronic Subscriber Identity Modules (eSIMs) on a mobile device, allowing each software application to be associated with a different eSIM, enabling granular access to wireless services based on individual application needs, such as bandwidth, data allotment, and security requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile device includes a physical SIM card slot and tray, then the device can store and switch between multiple subscriber identity modules, but the device size increases and user operation becomes more complex

Engineering Contradiction:
Improveability to store and switch between multiple subscriber identity modulesVSAvoiddevice structure complexity due to SIM card slot and tray
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses a virtual copy of the SIM card interface implemented through software. The virtual SIM card application replicates the functionality of a physical SIM card, allowing users to store and switch between multiple subscriber identity modules without requiring physical SIM card slots or trays. This software-based copy eliminates the need for mechanical components while maintaining the ability to manage multiple SIM profiles.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent extracts the essential functionality of the SIM card (subscriber identity storage and management) from its physical form and separates it from the device hardware. By taking out the SIM card's core function and implementing it as a standalone virtual application, the system eliminates the need for physical SIM card slots, trays, and associated mechanical components, thereby reducing device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a mobile device includes a SIM card tray and slot, then the device can accommodate physical SIM cards, but the ease of operation deteriorates due to additional manual steps required

Engineering Contradiction:
Improveability to use physical SIM cardsVSAvoiduser operation simplicity affected by SIM card tray manipulation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a virtual copy of the SIM card interface that can be accessed and managed entirely through software. Users can insert, remove, and switch between SIM profiles by interacting with the virtual SIM card application on the touchscreen, eliminating the need to manually manipulate physical SIM card trays and slots. This software-based approach significantly improves ease of operation while maintaining SIM functionality.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical system of physical SIM card insertion and tray manipulation with an electronic/software-based system. Instead of requiring users to physically open trays, insert cards, and close compartments, the system uses digital interfaces and software commands to achieve the same SIM card management functions, thereby eliminating mechanical operations and improving user ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a mobile device includes multiple physical SIM card slots, then the device can store multiple subscriber identity modules, but the device volume increases

Engineering Contradiction:
Improveability to store multiple subscriber identity modulesVSAvoiddevice volume increased by SIM card slots and trays
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent uses virtual copies of SIM cards stored in the device's memory or storage system. Multiple subscriber identity modules can be stored as digital files or data structures within the existing device memory, eliminating the need for additional physical SIM card slots. This approach maintains the ability to store multiple SIM profiles while utilizing already-present storage capacity, thereby avoiding any increase in device volume.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent makes the device's existing storage memory serve multiple functions: it stores not only the operating system and applications but also multiple virtual SIM card profiles. By making the storage system universal and multi-functional, the device can accommodate multiple subscriber identity modules without requiring dedicated physical SIM card slots, thereby avoiding any increase in device volume.

Inventive Principle:
Principle #6Universality (Multi-functionality)
