Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separated feed horns are used in conventional low noise block down-converters, then the system can receive satellite signals, but the circuit board layout size increases and system cost increases
Solution Approach 1:
The patent combines multiple separated feed horns into a single integrated feed horn structure with multiple waveguide openings. This merging approach allows multiple satellite signal reception functions to be achieved through one consolidated component, thereby reducing the circuit board layout size while maintaining the capability to receive signals from multiple satellites simultaneously.
Solution Approach 2:
The integrated feed horn structure serves multiple functions: it receives satellite signals from different directions through multiple waveguide openings, guides microwave signals through a single housing structure, and provides a unified interface to the circuit board. This multi-functionality eliminates the need for separate feed horns and reduces overall system complexity and cost.
2Reliability
If separated feed horns are used in conventional low noise block down-converters, then the system can receive satellite signals, but the system cost increases due to discrete electronic devices
Solution Approach 1:
The patent merges multiple discrete feed horn components and their associated waveguide structures into a single integrated housing with multiple waveguide openings. This consolidation reduces the number of discrete electronic devices and assembly steps, thereby lowering manufacturing costs while maintaining the ability to receive satellite signals from multiple sources.
Solution Approach 2:
The single housing structure performs multiple functions that previously required separate components: it contains multiple waveguide openings for different feed horns, provides signal guidance paths for multiple satellites, and interfaces with the circuit board through a unified structure. This multi-functionality reduces component count and system cost.
3Ease of manufacture
If waveguide transition structure is implemented, then integrated circuit devices can be used, but the housing structure becomes more complex
Solution Approach 1:
The housing structure is segmented into distinct functional zones: waveguide openings for signal entry, internal waveguide passages for signal routing, and transition structures for impedance matching. This segmentation allows the complex housing to be designed and manufactured as modular components, making the complexity manageable while achieving the goal of integrating multiple functions.
Solution Approach 2:
The waveguide transition structure acts as an intermediary between the multiple waveguide openings and the circuit board. It provides the necessary impedance matching and signal routing functions, enabling integrated circuit devices to be used effectively while managing the structural complexity through a dedicated transition zone.
