Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between devices through heterogeneous networks is inconvenient due to limitations in installing all functions in portable devices, making it difficult to share functions across different network types.
Innovation Solution
A system that enables function sharing between devices through a relay device connected to multiple networks, allowing devices to detect and interwork with external devices across various networks, such as Bluetooth, Wi-Fi, and broadband Internet, by using an external device detection controller, interworking controller, and function usage controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all functions are installed in portable electronic devices, then device functionality is improved, but device size and complexity increase
Solution Approach 1:
The patent introduces a server as an intermediary that hosts external devices and their functions. Portable electronic devices can access these functions through the server without having the functions installed locally, thus maintaining device portability while expanding functionality through network access.
Solution Approach 2:
The server is designed to universally support multiple external devices and multiple types of portable electronic devices. It provides a platform where various functions from different external devices can be accessed by different portable devices through a standardized interface, enabling multi-functionality without increasing individual device complexity.
2Adaptability or versatility
If devices communicate through heterogeneous networks, then network coverage is improved, but communication compatibility deteriorates
Solution Approach 1:
The server acts as a mediator between devices on heterogeneous networks. It receives requests from portable electronic devices, translates them into appropriate protocols for the target external devices, and relays the interactions. This intermediary approach enables communication across different network types while maintaining compatibility through standardized server interfaces.
3Volume of moving object
If portable electronic devices are miniaturized, then portability is improved, but installed function quantity deteriorates
Solution Approach 1:
The server serves as an external repository for device functions. Portable electronic devices maintain minimal local functionality for portability, while accessing additional functions from external devices through the server intermediary. This allows miniaturization without sacrificing function quantity, as functions are accessed remotely rather than stored locally.
