Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general detection of manufacturing environment is used, then indoor noise from reflection or scattering of ATE can be detected, but radio frequency noise around the element under test cannot be accurately detected
Solution Approach 1:
An antenna is introduced as an intermediary device to detect radio frequency noise in the manufacturing environment. The antenna receives radio frequency signals and converts them into electrical signals that can be processed by the detection circuit, enabling accurate detection of RF noise that would otherwise be undetectable by conventional methods.
Solution Approach 2:
The patent replaces conventional electrical noise detection methods with an antenna-based electromagnetic field detection system. The antenna captures radio frequency energy from the environment and converts it to electrical signals, substituting direct electrical measurement with electromagnetic field sensing for more accurate RF noise detection.
2Productivity
If radio frequency noise detection is not implemented, then manufacturing can proceed without restrictions, but testing results may be incorrect due to undetected noise
Solution Approach 1:
The detection device provides real-time feedback about radio frequency noise levels in the manufacturing environment. When excessive RF noise is detected, the system generates warning signals that alert operators to take corrective actions, enabling continuous monitoring and immediate response to maintain testing reliability without halting production.
Solution Approach 2:
The system performs preliminary detection of radio frequency noise before testing occurs, allowing proactive identification of problematic conditions. By detecting noise levels in advance, the system can alert operators to mitigate interference before it affects testing results, preventing incorrect test outcomes rather than detecting them after the fact.
3Measurement precision
If antenna is added to PCB for noise detection, then radio frequency noise can be detected, but device complexity increases
Solution Approach 1:
The antenna integrated into the PCB serves multiple functions: it acts as both a test signal interface and a radio frequency noise sensor. This multi-functionality reduces the need for separate detection hardware, minimizing the increase in device complexity while maintaining accurate noise detection capability.
Solution Approach 2:
The detection function is merged with the existing PCB structure by integrating the antenna directly into the board. This consolidation combines the test signal transmission function with the noise detection function in a single integrated structure, reducing overall system complexity compared to using separate detection equipment.

AI summary
The present invention provides an automatic detecting device for radio frequency environment used to detect radio frequency noise. The device uses an antenna to receive radio frequency noise and the radio frequency noise is passing a radio frequency comparator and transformed into a voltage signal. Then, the voltage signal passes through an amplifier and is amplified to be an output voltage. If the output voltage exceeds a threshold voltage, it drives a post stage circuit to warn when the radio frequency noise is beyond a normal value.
