Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current test schemes face difficulties in changing port configurations due to high technical thresholds, leading to rate mismatches between devices that result in communication failures and hinder effective testing.
Innovation Solution
A data switch with automatic parameter calculation and information processing capabilities, configured by user-defined direction and rate parameters, facilitates seamless communication and rate conversion among multiple devices, eliminating the need for repetitive program design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If programs are designed repeatedly to change port configuration, then port configuration can be changed, but technical threshold leads to difficulties in changing configuration
Solution Approach 1:
The data switch automatically calculates parameters and configures ports based on device connection information without requiring manual program design. The system serves itself by autonomously adapting port configurations when devices are connected, eliminating the need for users to repeatedly design programs for configuration changes.
2Reliability
If rate mismatch occurs between devices, then communication between devices fails, but testing becomes impossible
Solution Approach 1:
The data switch automatically adjusts transmission rates and other parameters to match between devices. When devices with different communication rates are connected, the switch modifies its port parameters dynamically to ensure compatible communication, preventing rate mismatch failures while maintaining testing capability.
3Adaptability or versatility
If manual program design is used for port configuration, then configuration can be changed, but technical threshold increases and operation becomes complex
Solution Approach 1:
The data switch acts as an intermediary that automatically handles the complex parameter calculation and port configuration tasks. Instead of users directly designing programs for configuration changes, the switch mediates between device connections and configuration requirements, automatically adapting to different test scenarios without requiring complex program design from users.
