Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing systems face inefficiencies in testing time and resource utilization, particularly when testers are physically distant from the test devices, as they require manual reconfiguration and lack efficient signal transmission methods.
Innovation Solution
A testing system with multiple test applying and testing portions connected via a switch portion that includes a first switch for selecting output ports, a second switch for selecting input ports, and a connecting portion with transmission parts of varying characteristics, allowing for efficient signal routing and parallel testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If testers are physically located at a distance from the objects to be tested, then the testing system can accommodate more test devices, but the testing time increases and resource utilization decreases
Solution Approach 1:
The testing system is divided into multiple independent test applying portions and testing portions that can operate simultaneously. Each testing portion can test different test devices in parallel, eliminating the sequential testing bottleneck and reducing total testing time while accommodating more devices.
Solution Approach 2:
The patent introduces a switch portion with multiple transmission parts that create additional signal transmission paths. This allows testers to be physically separated from test devices while maintaining efficient signal transmission through multiple parallel channels, resolving the contradiction between distance and testing efficiency.
2Adaptability or versatility
If testers are physically located at a distance from the objects to be tested, then the testing system can accommodate more test devices, but the resource utilization decreases
Solution Approach 1:
The testing system is divided into multiple independent test applying portions and testing portions that can operate simultaneously. Each testing portion can test different test devices in parallel, eliminating the sequential testing bottleneck and reducing total testing time while accommodating more devices.
Solution Approach 2:
The switch portion with multiple transmission parts serves multiple functions: it can route signals to different testing portions, support parallel testing operations, and accommodate various test devices. This multi-functionality improves resource utilization by allowing a single switching infrastructure to handle diverse testing configurations.
3Device complexity
If a simple switch configuration is used, then the device complexity is low, but the ability to support parallel testing and different transmission characteristics is limited
Solution Approach 1:
The switch portion is segmented into multiple independent transmission parts, each capable of supporting parallel signal transmission. This segmentation enables simultaneous testing operations while keeping each individual transmission path simple and manageable, balancing complexity with functionality.
Solution Approach 2:
The switch portion is designed with dynamic control capabilities that allow it to adaptively route signals to different testing portions based on real-time testing requirements. This dynamic switching enables parallel testing configurations without requiring complex static wiring arrangements for every possible scenario.
