Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems for air defense applications are complex and expensive due to the need for dedicated IP gateways at each radio site, leading to high capital and operational expenditures, as well as increased maintenance efforts.
Innovation Solution
A radio communication system where an external cryptographic device and ground-based radio are directly embedded in an IP network, eliminating the need for intermediate gateways by using integrated IP interfaces for encryption and decryption of voice signals, allowing for cost-efficient configuration and reduced component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated IP gateways are used at each radio site for encryption, then secure communication is achieved, but device complexity and capital expenditures increase
Solution Approach 1:
The patent combines multiple previously separate functions into a single integrated IP gateway device. The cryptographic device, voice communication system, and IP gateway functions are merged into one unit that can serve multiple radio sites, eliminating the need for separate dedicated gateways at each location while maintaining secure encrypted communication.
Solution Approach 2:
The IP gateway device is designed with multi-functionality to perform cryptographic operations, voice signal processing, and IP network communication simultaneously. This universal device can be dynamically assigned to serve different radio sites and multiple radios, replacing the need for dedicated single-function gateways at each location.
2Reliability
If dedicated IP gateways are deployed at each radio site, then encryption functionality is ensured, but operational expenditures and maintenance efforts increase
Solution Approach 1:
By merging the cryptographic device and voice communication system into a single IP gateway unit, the patent reduces the total number of devices that require maintenance. This consolidation means fewer components to monitor, update, and repair, directly reducing operational expenditures and maintenance efforts while preserving encryption functionality.
3Adaptability or versatility
If multiple gateways are deployed to support multiple radios at a site, then communication capacity is increased, but capital expenditures increase
Solution Approach 1:
The patent implements a universal IP gateway device that can dynamically serve multiple radios simultaneously through dynamic assignment. Instead of deploying separate dedicated gateways for each radio, this single multi-functional device can be allocated to different radios as needed, providing the required communication capacity while significantly reducing the total number of gateway devices required.
