Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting mode between line processing units (LPUs) and switch processing units (SPUs) in communications devices is not flexible enough, limiting the configuration and performance of communication systems.
Innovation Solution
A connecting apparatus is introduced that includes interconnection units connected to both LPUs and SPUs, allowing for flexible configurations by using a combination of connectors and printed circuit boards, including active and passive types, to enable various connection relationships and reduce signal attenuation through relay components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a printed circuit board backplane is used to connect LPUs and SPUs, then the connection structure is simple and stable, but the connecting mode flexibility is insufficient
Solution Approach 1:
The patent divides the connection system into independent interconnection units that can be selectively configured. Each interconnection unit represents a modular segment that can be independently connected to LPUs and SPUs, enabling flexible connection modes without requiring a complete redesign of the entire backplane structure.
Solution Approach 2:
The patent introduces dynamic configurability through switch processing units that can change connection states in real-time. The connection topology between LPUs and SPUs can be dynamically adjusted through software control, allowing the system to adapt to different operational requirements without physical reconfiguration.
2Adaptability or versatility
If detachable connectors are used between interconnection units and processing units, then the connecting mode flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent designs universal connectors that can accommodate multiple connection types and configurations. The same connector interface is used for different interconnection units and processing units, reducing the variety of connector types needed and simplifying the overall connection structure while maintaining flexibility.
Solution Approach 2:
The interconnection units serve as intermediary components between LPUs and SPUs. These intermediaries provide the detachable connection interfaces, isolating the complexity of configurable connections from the processing units themselves and simplifying their design.
3Reliability
If signal transmission is performed over long distances on the backplane, then signal attenuation occurs, but adding relay components increases device complexity
Solution Approach 1:
The patent extracts the signal regeneration function from the main backplane structure and places it within the interconnection units. This allows relay components to be selectively deployed only where long-distance signal transmission is needed, rather than throughout the entire system, reducing overall complexity while maintaining signal quality.
Solution Approach 2:
Interconnection units act as intermediary components that include relay functionality. These intermediaries regenerate and retransmit signals between LPUs and SPUs, ensuring signal integrity over long distances without requiring complex relay infrastructure across the entire backplane.
