Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microwave communication radios are susceptible to water leakage, have high manufacturing costs, and are bulky due to the use of discrete waveguide devices that are exposed to the elements and require complex die-casting and assembly.
Innovation Solution
An integrated radio design where the transmit-receive isolation, filtering, and polarization components are metal die-cast and sealed within a transmitter housing, eliminating the need for external components and reducing the radio's size and weight by integrating the waveguide structure into the housing plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discrete waveguide devices are used and exposed to elements, then transmit-receive isolation and polarization functions are achieved, but susceptibility to water leakage and manufacturing complexity increase
Solution Approach 1:
The patent combines multiple discrete waveguide devices (OMT, diplexer, polarizer) into a single integrated waveguide structure that is sealed within the housing. This merging eliminates the need for separate external components and their associated connections, directly reducing susceptibility to water leakage while simplifying the overall assembly process.
Solution Approach 2:
The waveguide structure is nested within the housing plates, with the transmit-receive isolation assembly integrated into the housing itself. This nesting approach protects the waveguide components from environmental exposure while maintaining a compact design, thereby improving reliability without increasing assembly complexity.
2Reliability
If discrete waveguide devices are used as separate external modules, then transmit-receive isolation function is achieved, but volume and mass increase
Solution Approach 1:
By merging the waveguide structure with the housing plates, the patent eliminates the need for separate external modules. This integration reduces the overall volume and mass of the radio while maintaining protection from environmental elements, as the housing itself serves as both structural support and protective enclosure.
3Ease of operation
If discrete waveguide devices are used, then polarization conversion is achieved, but manufacturing costs increase
Solution Approach 1:
The patent integrates the polarizer and other waveguide devices into a single molded structure, eliminating the need for separate manufacturing and assembly of multiple discrete components. This merging reduces manufacturing steps, material costs, and assembly operations, thereby lowering overall manufacturing costs while maintaining full polarization conversion capability.
4Reliability
If complex die-casting and assembly of discrete components is performed, then transmit-receive isolation assembly is formed, but productivity decreases
Solution Approach 1:
By combining multiple discrete components into a single integrated waveguide structure that can be molded as one piece, the patent eliminates multiple assembly steps. This merging maintains the quality and reliability of transmit-receive isolation functionality while dramatically improving manufacturing speed and productivity through reduced assembly operations.
