Bridge Device Identification via Standard Command Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a mechanism for identifying bridge devices, leading to potential software misappropriation and inefficient testing processes, as existing commands primarily focus on standard interface devices rather than bridge devices.
Innovation Solution
A method and system for identifying bridge devices by generating and responding to standard commands with no-available parameters, setting these parameters to predetermined values if a predefined command code is matched, allowing for accurate identification of bridge devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard commands are used to retrieve information of standard interface devices, then standard interface devices can be identified, but bridge devices cannot be identified
Solution Approach 1:
The patent modifies existing standard commands (IDENTIFY DEVICE and IDENTIFY PACKET DEVICE) to serve dual purposes: identifying both standard interface devices and bridge devices. By adding bridge device identification capability to existing commands, the system achieves multi-functionality without requiring entirely new command structures, thus resolving the contradiction between measurement precision and adaptability
2Reliability
If manufacturers develop separate software programs for testing bridge devices, then testing can be performed, but software misappropriation occurs easily
Solution Approach 1:
The patent enables bridge devices to identify themselves through standardized commands that return unique identification information. This self-identification capability eliminates the need for manufacturers to develop and distribute separate proprietary testing software, as the standardized interface allows any compliant software to perform testing, thereby reducing software misappropriation risks and management complexity while maintaining testing reliability

AI summary
Methods for identifying bridge devices and systems thereof. A bridge device receives a standard command. In response to the standard command, output information comprising at least one no-available parameter is generated. The bridge device sets the no-available parameter in the output information as a predetermined value if a command code or at least one no-available in the standard command matches a predefined value. The bridge device is identified by determining whether a value of the no-available parameter in the output information matches a predetermined value corresponding to a supported bridge device.
