Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component testing systems are limited by their expense, bulkiness, and inability to operate effectively in harsh environments, and they struggle with transmitting high-speed signals due to constraints in signal transmission media such as wires, which restricts remote and efficient testing of high-speed electronic devices.
Innovation Solution
A remote testing system comprising a user device, a remote testing unit (RTU) with two communication modules, and a signal generation and detection module, enabling the generation and reception of test signals over a communication network to test and probe electronic components, sensors, and detectors, allowing for flexible and efficient operation of high-speed devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional specialized testing systems are used, then testing capability is provided, but the systems are expensive, bulky, and unsuitable for harsh environments
Solution Approach 1:
The system divides testing functions into two separate units: a centralized server that performs complex signal generation and analysis, and a portable remote testing unit that only handles signal transmission and basic control. This segmentation allows the expensive, complex components to remain stationary while the portable unit can be deployed to harsh environments.
Solution Approach 2:
A communication network acts as an intermediary between the portable testing unit and the centralized server. The portable unit sends minimal control signals and receives processed test data through this intermediary, eliminating the need for bulky local processing equipment while maintaining full testing capability.
2Reliability
If electrically conducting wires are used for signal transmission, then connection is established, but signal transmission is constrained by non-instantaneous travel time and physical limitations at high speeds
Solution Approach 1:
The system replaces electrical signal transmission through conducting wires with optical signal transmission through optical fibers. This substitution eliminates the physical limitations of electrical wires at high frequencies, enabling accurate transmission of multi-gigahertz test signals over longer distances with reduced attenuation and interference.
3Adaptability or versatility
If remote testing is implemented, then accessibility to harsh environments is improved, but signal transmission distance and quality are constrained
Solution Approach 1:
Optical fibers replace electrical wires for signal transmission, enabling high-quality signal transmission over much longer distances. The optical transmission medium is immune to electromagnetic interference and signal degradation that plagues electrical wires, allowing portable testing units to operate effectively hundreds of feet from the device under test while maintaining signal integrity.
