Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional telemetry systems are used to monitor power distribution networks, then system complexity is reduced, but measurement precision and information granularity deteriorate
Solution Approach 1:
The patent introduces cable service devices as intermediary components that bridge the CATV distribution network and power distribution network. These devices measure power quality parameters (voltage, frequency) at consumer locations and transmit data through the existing CATV infrastructure, achieving granular monitoring without directly modifying the power distribution system.
Solution Approach 2:
The cable service devices perform multiple functions: providing cable services (TV, internet) and simultaneously measuring power quality parameters. This multi-functionality allows the system to achieve precise power monitoring using existing infrastructure, reducing overall system complexity while improving measurement precision.
2Measurement precision
If granular power quality monitoring at consumer level is implemented, then measurement precision improves, but device complexity and infrastructure requirements worsen
Solution Approach 1:
The patent merges the power quality monitoring function with existing cable service devices. By combining these functions, the system achieves consumer-level measurement precision without adding separate monitoring infrastructure, thereby reducing overall device complexity.
Solution Approach 2:
The cable service devices, which are already deployed at consumer locations for providing cable services, are utilized to simultaneously perform power quality measurements. This self-service approach eliminates the need for dedicated monitoring equipment at each consumer location.
3Loss of information
If heterogeneous network integration is implemented, then information completeness improves, but device complexity and operational complexity worsen
Solution Approach 1:
The HNTMC device serves as an intermediary that integrates data from heterogeneous networks (CATV and power distribution networks). It receives power quality measurements from cable service devices and combines them with network topology information, achieving complete information integration without direct complex interconnection between the two networks.
Solution Approach 2:
The system implements feedback mechanisms where the HNTMC device processes integrated information and provides control signals back to power distribution network devices. This feedback loop enables adaptive control based on comprehensive information from both networks, improving information completeness while managing complexity through structured feedback pathways.
