Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intelligent circuit breakers are reformed to create interaction devices for demand response, then low-voltage users can participate in demand response programs, but the device complexity increases due to multiple functional modules
Solution Approach 1:
The interaction device integrates multiple functions including protection, data acquisition, load determination, blockchain operations, and demand response management into a single unified device. This multi-functional integration enables low-voltage users to participate in demand response programs while maintaining a compact device structure rather than requiring separate devices for each function.
Solution Approach 2:
The patent combines the intelligent circuit breaker with additional functional modules (protection module, data acquisition module, load determination module, blockchain module, and demand response module) into an integrated interaction device. This merging approach consolidates multiple capabilities into one device, reducing the need for multiple separate components while enabling comprehensive demand response participation.
2Adaptability or versatility
If multiple functional modules are integrated into the interaction device, then the functionality and intelligence are enhanced, but the manufacturing cost increases
Solution Approach 1:
By designing a multi-functional interaction device that performs protection, data acquisition, load analysis, blockchain operations, and demand response management simultaneously, the patent achieves comprehensive functionality. This universal design allows a single device to replace multiple specialized devices, potentially reducing overall system cost despite the enhanced capabilities of individual modules.
3Reliability
If data acquisition and processing functions are added to monitor distribution line information, then the reliability of service data is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The data acquisition module serves as an intermediary between the distribution line and the control processor, collecting and preprocessing data before transmission. This intermediary function ensures reliable data collection while simplifying the processing burden on the control processor, as the module handles initial data filtering and organization.
Solution Approach 2:
The interaction device implements continuous monitoring and feedback mechanisms where distribution line information is acquired, processed, and used to adjust demand response strategies in real-time. This feedback loop enhances data reliability by continuously validating and updating system state information, enabling more accurate load determination and demand response management.
4Reliability
If blockchain modules are integrated for credible recording and automatic settlement, then the transparency and trustworthiness of demand response transactions are improved, but the device complexity and computational requirements increase
Solution Approach 1:
The blockchain module enables automatic settlement and credible recording of demand response transactions without requiring manual intervention or external verification. The device autonomously performs transaction recording, smart contract execution, and settlement operations, enhancing trustworthiness while reducing operational complexity through automation rather than adding manual processing steps.
