Solution Overview

Problem

Users face inconvenience and increased financial expenditure due to the need to carry and manage multiple mobile phones to access multiple telecommunication networks and phone numbers, as existing devices can only utilize a single subscriber identity module (SIM) card.

Innovation Solution

A communication apparatus with a central controlling device and dual communication circuits that allow simultaneous access to two telecommunication networks using different subscriber identities, employing AT or binary commands for controlling short message service operations, enabling a single handheld device to manage multiple SIM cards and networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single mobile phone utilizes only a single SIM card, then the device structure remains simple, but the user cannot access multiple telecommunication networks simultaneously

Engineering Contradiction:

Improveaccess to multiple telecommunication networksVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple communication circuits (first communication circuit and second communication circuit) into a single mobile phone device, allowing simultaneous access to multiple telecommunication networks through integrated hardware architecture

Inventive Principle:
