Solution Overview

Problem

Conventional dual-mode mobile communication devices cannot share a Bluetooth module for communication, limiting their ability to simultaneously use Bluetooth devices with multiple communication modules, which is inconvenient for users.

Innovation Solution

A dual-mode mobile communication device comprising a first and second communication module, with a Bluetooth module electrically connected to both, allowing wireless connection to a Bluetooth device, enabling both modules to share the Bluetooth module for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional dual-mode mobile apparatus uses only one communication module to access Bluetooth devices, then the Bluetooth module can be used for communication, but the other communication module cannot use Bluetooth devices, causing inconvenience for users

Engineering Contradiction:

ImproveBluetooth module sharing capabilityVSAvoidUser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The Bluetooth module is designed to serve multiple communication modules (both first and second communication modules) rather than being dedicated to a single module. The switching mechanism enables the Bluetooth module to be universally accessed by either communication module based on operational needs, implementing multi-functionality that resolves the limitation of single-module access.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs a dynamic switching mechanism that allows the Bluetooth module to be flexibly allocated between the first and second communication modules. The switch can dynamically change connections based on which communication module is actively operating, providing adaptability and user convenience without requiring separate Bluetooth modules for each communication mode.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If separate Bluetooth modules are provided for each communication module, then each module can independently use Bluetooth devices, but the device complexity and cost increase

Engineering Contradiction:

ImproveIndependent Bluetooth access capabilityVSAvoidNumber of Bluetooth modules

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of providing separate Bluetooth modules for each communication module, the invention merges the Bluetooth functionality into a single shared module. This consolidation reduces device complexity and component count while maintaining the capability for both communication modules to access Bluetooth devices through the shared resource and switching mechanism.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switching mechanism acts as an intermediary that enables both communication modules to access the single Bluetooth module. This mediator component allows independent Bluetooth access capability for each communication module without requiring physical separate Bluetooth modules, thus reducing overall device complexity while maintaining functional independence.

Inventive Principle:

Principle #24Intermediary (Mediator)
