Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional filter structure is used, then the device complexity is low, but the signal detection capability is insufficient
Solution Approach 1:
The patent combines the signal output function and signal detection function into a single integrated module. The signal output unit includes both the signal output port and the detection module with probe and coupling plate, allowing the filter to simultaneously output signals and detect their quality without requiring separate detection equipment, thus improving reliability while controlling device complexity
Solution Approach 2:
The signal output unit is designed to perform multiple functions: it serves as both the signal output interface and the signal detection interface. The coupling plate and probe structure enables the same physical component to both transmit signals outward and detect signal quality, making the device more versatile and reducing the need for additional components
2Measurement precision
If no signal detection module is added, then the device complexity remains low, but the measurement precision of signal quality is insufficient
Solution Approach 1:
The patent introduces a coupling plate as an intermediary component between the signal output port and the probe. The coupling plate couples the electromagnetic field from the signal output to the probe, enabling accurate signal quality detection. This intermediary structure allows precise measurement without requiring direct access to the signal source, improving measurement precision while adding only moderate complexity
Solution Approach 2:
The patent replaces potential external mechanical detection systems with an integrated electromagnetic field-based detection module. The probe detects signal quality through electromagnetic coupling rather than physical connection, eliminating the need for complex mechanical interfaces while achieving high measurement precision

AI summary
A filter includes a base and a sidewall extending from the base. The base and the sidewall cooperatively define a cavity. The filter further includes a signal input unit, and a signal output unit having a signal output port. The signal output port is located on the sidewall and extends outside of the cavity. The signal output port is connected to a conductive post received within the cavity. The conductive post collects radio signals and outputs the collected radio signals via the signal output port. The signal output unit further includes a signal detection module. The signal detection module includes a coupling plate, a coupling signal output terminal, and a probe. The coupling plate is electrically connected to the probe. The probe is located adjacent to the conductive post to receive radio signals surrounding the conductive post and output the received radio signals via the coupling output terminal.
