Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power dividing and combining circuits are used with wide frequency signals, then signal transmission capability is improved, but interference with other electronic components increases
Solution Approach 1:
The circuit divides the wide frequency signal into multiple segmented frequency bands using high pass and low pass filtering modules. Each filtering unit processes a specific frequency range separately, allowing selective transmission of desired signals while blocking interfering frequencies, thus resolving the contradiction between wide frequency capability and interference reduction
Solution Approach 2:
Filtering modules are introduced as intermediary components between the power dividing/combining circuits and other electronic components. These intermediaries selectively pass certain frequency ranges while attenuating others, acting as a mediator that maintains signal transmission capability while reducing harmful interference to surrounding components
2Object-generated harmful factors
If filtering modules are added to the power dividing and combining circuit, then interference is reduced, but device complexity increases
Solution Approach 1:
The filtering modules are designed to perform multiple functions simultaneously: they filter unwanted frequencies, divide power signals, and combine amplified signals. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving effective interference reduction
Solution Approach 2:
The high pass and low pass filtering units are merged into a unified filtering module structure that integrates seamlessly with the power dividing and combining circuits. By combining filtering functionality with the existing power signal processing path, the circuit achieves interference reduction without proportionally increasing overall device complexity
