Protocol-Switching Information Processing Device Without Application Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle devices require modification of applications to switch between TCP/IP and original protocol sets for communication, which is inconvenient and inefficient.
Innovation Solution
An information processing device with dual communication processing units, one for TCP/IP and another for an original protocol set, allows seamless switching between protocols without modifying the application, by transmitting data to the appropriate unit based on predetermined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application is modified to switch between protocol sets, then communication flexibility is improved, but application complexity and maintenance difficulty increase
Solution Approach 1:
The patent introduces a communication processing unit as an intermediary layer between the application and the communication interface. This unit automatically selects and switches between TCP/IP and original protocol sets based on communication conditions, eliminating the need for application modification while maintaining protocol switching capability
Solution Approach 2:
The communication functionality is segmented into independent components: the application layer remains unchanged, while the communication processing unit handles protocol selection and switching. This separation allows protocol flexibility without increasing application complexity
2Adaptability or versatility
If the application is modified to support protocol switching, then communication compatibility is improved, but development cost and time increase
Solution Approach 1:
The communication processing unit serves as a mediator that handles all protocol-related operations, allowing existing applications to maintain compatibility with both TCP/IP and original protocol sets without any development or modification costs
Solution Approach 2:
The communication processing unit is designed to handle multiple protocol sets (TCP/IP and original protocols) within a single component, providing universal communication capability that works with existing applications without requiring separate development for each protocol
3Adaptability or versatility
If dual communication processing units are implemented, then protocol switching capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple communication processing capabilities (TCP/IP handling and original protocol handling) into a single integrated communication processing unit, avoiding the need for separate dual communication processing units while maintaining protocol switching capability
Solution Approach 2:
The communication processing unit dynamically selects and switches between different protocol sets based on communication conditions, providing adaptive protocol handling without requiring permanent, static configuration of multiple communication interfaces

AI summary
The present invention implements switching between two protocol sets without correcting an application. An information processing device includes: a first communication processing unit for performing a communication with a first external device according to a first protocol set; and a second communication processing unit for performing a communication with a second external device according to a second protocol set, wherein, when a predetermined condition is not satisfied, the first communication processing unit transmits data received from an application to the first external device and, when the predetermined condition is satisfied, transmits the data to the second communication processing unit according to the first protocol set, and wherein the second communication processing unit transmits the data received from the first communication processing unit to the second external device according to the second protocol set.
