Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If device operations are controlled based on time-based price information, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
A control device is introduced as an intermediary between the power supplier and controlled devices. The control device receives time-based price information from the power supplier and operation limiting information from controlled devices, then determines appropriate power consumption levels and transmits control commands. This intermediary handles the complexity of decision-making, keeping individual controlled devices simple while achieving overall energy optimization.
Solution Approach 2:
The system segments the control function into separate components: the control device handles information processing and decision-making, while controlled devices simply execute commands. This segmentation allows the complex control logic to be centralized in one device, reducing the complexity burden on individual controlled devices while maintaining effective energy management.
2Measurement precision
If operation limiting information is collected from multiple devices, then energy management precision is improved, but network complexity increases
Solution Approach 1:
The control device merges information from multiple controlled devices into a unified power consumption management system. By collecting operation limiting information from various devices and consolidating control decisions, the system achieves precise overall power consumption management without requiring complex peer-to-peer interactions between devices, thus reducing network complexity.
Solution Approach 2:
The control device serves as a central intermediary that collects operation limiting information from multiple controlled devices, processes this information along with time-based price signals, and coordinates control commands. This centralized intermediary approach enables precise power consumption control across multiple devices while simplifying the network structure compared to distributed control architectures.
3Loss of energy
If device operations are adjusted to meet power consumption levels, then energy efficiency is improved, but operational flexibility is reduced
Solution Approach 1:
The control system dynamically adjusts device operations based on real-time time-based price information and current power consumption levels. Rather than fixed control rules, the system adapts its control commands according to varying conditions, allowing devices to maintain operational flexibility while meeting power consumption targets. The control device can modify operation limiting information and power consumption levels dynamically in response to changing conditions.
