Integrated Signal Processing Unit for High-Frequency Device Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern electronic device testing at high frequencies is challenging due to the complexity and error-prone nature of traditional setups, which are affected by environmental conditions and cable movements, making reliable measurements difficult, especially as devices become smaller.
Innovation Solution
A signal processing unit with a separate test chamber that integrates into a main housing, eliminating the need for external cables and test housings, featuring detachable or permanently fixed coupling, shielding, and optional features like cameras and antennas for improved reliability and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional test setups with external cables and test housings are used, then device testing can be performed, but measurement reliability deteriorates due to environmental conditions and cable movements
Solution Approach 1:
The patent merges the test chamber and measurement device into a single integrated unit. The test chamber is permanently coupled to the main housing of the measurement device, eliminating the need for external cables and separate test housings. This integration removes the sources of measurement instability (cable movements, environmental sensitivity) while reducing overall setup complexity.
Solution Approach 2:
The patent extracts and eliminates the problematic external cables and separate test housings from the measurement system. By removing these external connections and replacing them with an integrated test chamber design, the sources of measurement error and environmental sensitivity are eliminated.
2Volume of moving object
If devices under test become smaller to accommodate higher frequencies, then device size is reduced, but test chamber size must also be reduced making integration more difficult
Solution Approach 1:
The test chamber is permanently integrated into the main housing of the measurement device, creating a compact unified structure. This merging allows the test chamber to be miniaturized along with the overall device, accommodating smaller high-frequency devices under test while maintaining structural stability and reducing integration complexity.
3Productivity
If external cables and separate test housings are used, then testing can be performed, but test preparation effort increases and errors occur
Solution Approach 1:
The integration of the test chamber into the measurement device eliminates the need for separate test housings and external cable connections. This unified design simplifies test preparation by removing assembly steps and reduces test errors by eliminating unstable external connections that could cause measurement failures.
