Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device testing systems are limited in their ability to simultaneously test multiple devices of different types without requiring significant architectural changes and do not allow for real-time, bi-directional, asynchronous communication, making it difficult to control and monitor multiple devices independently during testing.
Innovation Solution
A system with a core testing subsystem and user interface that uses web sockets for real-time, bi-directional asynchronous communication, allowing for the simultaneous testing of disparate devices with adaptable interfaces that can be extended to include new devices without altering the core architecture, utilizing a three-layer implementation with a test bench browser interface, web sockets, and a core testing processor for TCP/IP communication and JSON data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional testing systems are used to test multiple devices simultaneously, then device testing capability is limited, but system complexity and architectural changes required increase significantly
Solution Approach 1:
The patent implements a universal testing system where a single testing interface can handle multiple device types simultaneously. The system uses standardized communication protocols and a common testing framework that adapts to different devices through configuration rather than architectural changes, allowing one system to serve multiple testing functions across diverse device types.
Solution Approach 2:
The testing system is divided into independent modular components including separate testing interfaces, communication modules, and device handlers. Each device type can be tested through its own interface instance while sharing common infrastructure, allowing simultaneous testing without interference and enabling easy addition of new device types without affecting existing functionality.
2Measurement precision
If real-time monitoring and control of multiple devices is implemented, then device control precision improves, but communication system complexity increases
Solution Approach 1:
The patent introduces web sockets as an intermediary communication mechanism between the testing interface and devices under test. This provides real-time bidirectional asynchronous communication that enables precise monitoring and control of multiple devices simultaneously without requiring complex point-to-point communication architecture, simplifying the system while maintaining high precision control.
3Adaptability or versatility
If new device types are added to the testing system, then system versatility improves, but architectural changes and reconfiguration requirements increase
Solution Approach 1:
The testing system implements dynamic adaptability where the interface can automatically adjust to new device types through runtime configuration and device detection. New devices can be added without system reconfiguration or architectural changes - the system dynamically loads appropriate handlers and communication protocols based on device identification, making the system as adaptable as it is easy to configure.
