Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a power-saving control system is implemented to reduce electricity consumption, then power-saving efficiency is improved, but the system cannot appropriately respond to forcible power restrictions or power interruptions
Solution Approach 1:
The system performs preliminary actions by storing electricity in advance using a secondary battery when power is available. The control device monitors power consumption and charges the battery during periods when power usage is below the contract amount, preparing energy reserves before power restrictions occur. This allows the system to maintain operation during forcible power restrictions without compromising either power-saving efficiency or reliability.
Solution Approach 2:
The secondary battery serves as a cushioning mechanism that absorbs excess power availability and provides compensation during power interruptions. By accumulating energy in advance, the system creates an energy buffer that protects against the harmful effects of power restrictions, ensuring continuous operation of essential devices while maintaining overall power-saving goals.
2Use of energy by moving object
If the contract amount of electricity is reduced through power-saving control, then power consumption is decreased, but the system lacks means to respond when actual usage exceeds the reduced contract amount
Solution Approach 1:
The control device continuously monitors power consumption data and compares it against the contract amount, creating a feedback loop. When actual usage approaches or exceeds the reduced contract amount, the system receives feedback signals and automatically adjusts by transferring load to the secondary battery or reducing power consumption of non-essential devices. This dynamic feedback mechanism enables the system to adapt to varying power availability while maintaining operational flexibility.
Solution Approach 2:
The system dynamically adjusts power allocation between the primary power supply and secondary battery based on real-time conditions. The control device can flexibly switch power sources and adjust the operating state of connected devices, transforming the rigid contract amount constraint into a dynamic power management strategy that responds to actual usage patterns and availability.
3Productivity
If individual device control is implemented for power-saving, then power allocation efficiency is improved, but the system cannot provide coordinated response across multiple devices during power restrictions
Solution Approach 1:
The system merges individual device control with centralized battery management by connecting all devices to a common power control architecture. The control device aggregates power consumption data from multiple devices and coordinates their operation based on overall power availability and battery charge status. This unified approach maintains the efficiency benefits of individual device control while adding the adaptive capability of coordinated system-wide response during power restrictions.
Solution Approach 2:
The secondary battery serves multiple functions simultaneously: it acts as an energy storage device, a backup power source, and a load balancing mechanism across multiple devices. The control device universally manages power distribution to all connected devices based on priority levels and current power availability, enabling a single system to handle diverse power management requirements and provide coordinated response during restrictions.
