Solution Overview

Problem

Conventional dual SIM extenders require users to physically swap SIM cards and lack active dual SIM management capabilities, making it cumbersome to switch between different identities and monitoring levels for personal and work communications.

Innovation Solution

An apparatus with dual SIM interfaces that includes a housing for a personal communication device and a controller to selectively couple SIM interfaces to the device's SIM slot, allowing seamless switching and active monitoring of selected SIM cards through a personal communication device interface with integrated switches and a SIM emulator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional dual SIM extenders are used to insert multiple SIM cards, then the user can have multiple identities available, but the user must manually swap SIM cards or use conventional extenders that still require user intervention for switching

Engineering Contradiction:

Improvemulti-identity supportVSAvoidSIM switching operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system enables self-service SIM card switching by automatically detecting when a SIM card is inserted and initiating the switching process without requiring manual user intervention. The controller automatically couples the detected SIM card interface to the personal communication device's SIM slot, eliminating the need for users to manually swap cards or use conventional extenders that require user intervention.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system prepares multiple SIM card interfaces in advance within the housing, allowing them to be ready for automatic selection. When a SIM card is inserted, the controller has already positioned the appropriate interface for coupling, enabling seamless switching before the user even needs to make a selection.

Inventive Principle:

Principle #10Preliminary action

2Quantity of substance

If conventional dual SIM extenders are used, then multiple SIM cards can be stored, but active dual SIM management and monitoring capabilities are not available

Engineering Contradiction:

Improvenumber of SIM cardsVSAvoidactive SIM management

Core Design Contradiction:

Quantity of substanceVSExtent of automation

Solution Approach 1:

The system implements feedback mechanisms where the controller continuously monitors which SIM card interface is coupled to the personal communication device and provides status information about the selected SIM card. This enables active management and monitoring of SIM card usage, allowing the system to track and report on SIM card selection and communication activity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system replaces manual mechanical SIM card swapping with an automated electrical coupling mechanism. The controller uses electrical signals to automatically connect the appropriate SIM card interface to the personal communication device's SIM slot, eliminating the need for physical handling and manual insertion/removal operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If a single SIM interface is used in the personal communication device, then the device structure remains simple, but the device cannot support dual SIM functionality without external extenders

Engineering Contradiction:

ImproveSIM interface configurationVSAvoiddual SIM capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system segments the SIM card storage and interface functions into separate components within the housing. Multiple SIM card interfaces are provided in the housing, separate from the single SIM slot in the personal communication device. This segmentation allows the device to maintain a simple internal structure while providing dual SIM capability through the external housing interfaces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The housing acts as an intermediary component between the user and the personal communication device. It provides the additional SIM card interfaces and physical space for storing multiple SIM cards, while the controller serves as an intermediary that manages the electrical connection between the housing interfaces and the device's SIM slot, enabling dual SIM functionality without complicating the device's internal architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)
