Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks, especially those with inaccessible nodes like satellites, face challenges in maintaining redundancy for communication paths due to complex switch network designs that fail to efficiently reroute signals upon multiple component failures without affecting other channels.
Innovation Solution
A redundant ferrite switch system comprising multiple circulator modules with a circulator switch controller to route signals through a network that can withstand failures of up to three communication paths, using a combination of base circulator modules and 2-for-1 redundant triad switches to ensure uninterrupted communication by rerouting paths without disrupting other channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If order constrained networks of ferrite circulators are used to provide N for M redundancy, then communication path redundancy is achieved, but the switch network design becomes complex and cannot be reused for different N and M combinations
Solution Approach 1:
The switch network is divided into multiple identical modular units, each handling a specific routing function. These modules can be independently designed, tested, and reused across different N and M configurations, reducing overall design complexity while maintaining redundancy capabilities.
Solution Approach 2:
The patent creates a universal modular switch network design that can be configured for different N for M redundancy scenarios. The same basic module structure serves multiple functions and can be adapted to various input/output port combinations, eliminating the need for custom designs for each redundancy configuration.
2Reliability
If standby equipment is added to inaccessible communication nodes, then reliability against component failures is improved, but the overall system complexity increases
Solution Approach 1:
The redundant system is segmented into standardized modules that can be independently managed and controlled. This modular approach allows the standby equipment to be integrated systematically rather than ad-hoc, reducing the complexity burden of added redundancy components.
Solution Approach 2:
The switch network incorporates automatic failure detection and rerouting capabilities that operate without external intervention. When a component fails, the system automatically switches communication paths through standby equipment, eliminating the need for manual reconfiguration and reducing operational complexity.
3Reliability
If the switch network reroutes communication paths upon component failure, then communication continuity is maintained, but the switching mechanism complexity increases
Solution Approach 1:
The switching function is divided into discrete modular units that can independently perform rerouting operations. Each module handles specific switching logic, making the overall switching mechanism more manageable and less complex than a monolithic switching system.
Solution Approach 2:
The switch network is pre-configured with multiple possible communication paths and routing logic before failures occur. When a component fails, the system immediately activates pre-planned rerouting sequences, eliminating the need for complex real-time decision-making and reducing switching mechanism complexity.
