Solution Overview

Problem

Existing mobile devices are heavy and bulky due to large-sized components and heavy batteries, limiting their portability and functionality.

Innovation Solution

A modular communication system comprising a lightweight control module that wirelessly communicates with a docking station module, where the control module uses short-range radio for data exchange and the docking station module uses long-range radio for cellular network communication, allowing the control module to leverage high-power components while minimizing its own power consumption and size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing mobile devices use large-sized components and heavy batteries to provide robust functionality, then the device can perform multiple functions including telephonic, messaging, and PIM applications, but the device becomes heavy and bulky, limiting portability

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The mobile device is divided into two separate modules: a lightweight control module containing only essential components (processor, display, short-range radio) and a separate docking station module containing the heavy components (long-range radio, large battery, connector terminals). This segmentation allows the control module to be portable while the docking station provides robust functionality when docked.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heavy and bulky components (long-range radio, large battery, connector terminals) are extracted from the control module and placed in a separate docking station module. This extraction eliminates the weight and bulk constraints on the control module while preserving full functionality through the docking station.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If existing mobile devices use large-sized components and heavy batteries, then full functionality is achieved, but the device bulk increases, affecting portability

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice bulk
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The device is segmented into a compact control module for portability and a separate docking station for full functionality. The control module contains only essential components (processor, display, short-range radio) minimizing volume, while the docking station houses the bulkier components (long-range radio, large battery, connector terminals).

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bulky components are extracted from the control module and relocated to the docking station. This extraction reduces the control module volume to a portable size while the docking station provides full functionality when connected.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the control module uses high-power components for full functionality, then all communication capabilities are available, but power consumption and battery requirements increase

Engineering Contradiction:
Improvecommunication capabilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

Communication capabilities are segmented into short-range radio in the control module (low power) and long-range radio in the docking station (high power). This segmentation allows the control module to operate with low power consumption for basic communication, while full communication capability is restored when docked with the high-power long-range radio.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The high-power long-range radio component is extracted from the control module and placed in the docking station. This extraction eliminates the need for the control module to carry heavy battery power requirements, as the high-power communication is only needed when docked.

Inventive Principle:
Principle #2Taking out (Extraction)
