Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data relay is performed through multiple layers of device controllers with extensive processing and memory usage, then communication coverage and device control capability are improved, but latency and power consumption increase
Solution Approach 1:
The patent extracts the essential relay function from complex multi-layer device controller processing and implements it directly at the PHY layer through a switching matrix. This removes unnecessary processing steps while maintaining communication coverage, thereby reducing latency significantly.
Solution Approach 2:
The switching matrix acts as an intermediary component that enables direct signal redirection between transceivers without requiring data packet extraction and repacking by processors. This intermediary structure maintains communication capability while eliminating processing delays.
2Adaptability or versatility
If data relay is performed through multiple layers of device controllers with extensive processing and memory usage, then communication coverage and device control capability are improved, but power consumption increases
Solution Approach 1:
The patent extracts the relay function from processor-based data packet handling and implements it at the PHY layer using a switching matrix. This eliminates the need for memory access and processor computation in relay operations, significantly reducing power consumption while maintaining device control capability.
Solution Approach 2:
The switching matrix performs relay operations autonomously at the physical layer without requiring processor intervention or memory resources. This self-service capability at the PHY layer reduces the power burden on the processor while maintaining full device control functionality.
3Ease of operation
If special memory mapping is required for systems without processors, then relay operation is enabled, but device complexity and memory mapping complexity increase
Solution Approach 1:
The patent replaces the mechanical/memory-based relay approach (requiring special memory mapping) with an electrical signal switching approach using a switching matrix at the PHY layer. This substitution eliminates complex memory mapping requirements while enabling straightforward relay operation.
