Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable mobile communication terminals face spatial limitations, making it difficult to add application hardware, requiring users to purchase and replace battery modules for different functions and limiting the provision of multiple additional functions.
Innovation Solution
A communication terminal design that includes a battery pack and an additional function module with a communication path and processor, allowing for the provision of multiple additional functions without the need for new terminal purchases, using a DC power path and an AC signal path for full-duplex communication.

Engineering Contradiction Analysis
1Weight of moving object
If a communication terminal is manufactured in a small size, then portability is improved, but the ability to add application hardware deteriorates due to spatial limitations
Solution Approach 1:
The additional function module is nested within the battery pack structure, utilizing the existing spatial volume of the battery pack to house extra functionality. This allows the terminal to gain additional capabilities without increasing the overall terminal size, as the additional module is embedded within the existing battery compartment space.
Solution Approach 2:
The battery pack is designed to serve multiple functions: it provides power supply through the battery cell and simultaneously hosts additional function modules that can be connected to the terminal main body. This multi-functional design allows a single component (battery pack) to fulfill both power delivery and application hardware provision roles.
2Adaptability or versatility
If users purchase and replace battery modules for different functions, then additional functions can be added, but the complexity of continuously replacing modules increases
Solution Approach 1:
The battery pack is designed as a universal platform that can accommodate multiple different additional function modules through the same connection interface. Users can attach different modules (camera, music player, etc.) to the same battery pack, eliminating the need to purchase entirely different battery modules for different functions and reducing replacement complexity.
3Adaptability or versatility
If wired or wireless ports are used to connect external devices, then additional functions can be achieved, but the spatial limits of the terminal are further constrained
Solution Approach 1:
The connection interface for additional function modules is nested within the battery pack assembly rather than requiring separate external ports on the terminal main body. This integration utilizes the existing battery pack connection points and routing, avoiding the need for additional spatial allocation on the terminal chassis for separate wired or wireless connection hardware.

AI summary
A terminal main body of a communication terminal is supplied power from a battery pack through a DC signal path. The terminal main body communicates with at least one additional function module providing an additional function through a communication path connected to the DC signal path so as to provide the additional function to a user. Herein, the communication path is an AC signal path. That is, a signal transmitted/received between the terminal main body and the additional function module is an AC signal, and thus, the communication path can be compatible with the DC signal path providing the power. In addition, a plurality of additional function modules can be serially connected in the form of a serial communication bus, and therefore, a user can select a plurality of additional functions.
