Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If line digital signal processing is performed on each individual line processing device, then processing capability is provided for each line, but device complexity and operation and maintenance costs increase
Solution Approach 1:
The patent merges the line digital signal processing functions from multiple individual line processing devices into a single centralized processing device. This centralized device receives service data from multiple line access modules and performs unified line digital signal processing, thereby reducing overall system complexity while maintaining processing capability for all lines simultaneously
Solution Approach 2:
The centralized processing device is designed to handle service data from multiple different access modes (ADSL, VDSL, G.fast, etc.) through a universal processing architecture. The device can perform different line digital signal processing methods for different access modes within a single unified system, reducing the need for multiple specialized devices
2Reliability
If line digital signal processing is performed on each individual line processing device, then processing capability is provided for each line, but operation and maintenance costs increase
Solution Approach 1:
By consolidating line digital signal processing functions into a single centralized device, the patent reduces the number of devices that require monitoring, maintenance, and alarm processing. This merging approach directly lowers operation and maintenance costs while preserving the ability to process service data from multiple lines simultaneously
3Adaptability or versatility
If multiple line access modules are integrated with full processing functions, then comprehensive service processing is achieved, but device complexity and costs increase
Solution Approach 1:
The patent segments the processing functions by separating line access functions (handled by multiple line access modules) from line digital signal processing functions (handled by a centralized processing device). This segmentation allows each module to be simpler while the system as a whole maintains comprehensive service processing capability through coordinated operation
Solution Approach 2:
The centralized processing device acts as an intermediary that receives service data from multiple line access modules and performs the complex line digital signal processing. This intermediary approach allows line access modules to remain relatively simple while still achieving comprehensive service processing through the centralized mediator
