Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems are limited by their inability to adapt to real-time pricing rates and cannot efficiently manage power distribution across multiple consumers, leading to inflexible charging structures and inefficient energy usage.
Innovation Solution
A power supply control apparatus comprising a connection unit, a charging unit, and a controller that compares real-time rate information with a preset control reference to dynamically control power exchange and distribution, allowing for flexible charging and distribution based on current energy rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power supply control is based on preset time slots, then power distribution is simplified and easy to implement, but the system cannot adapt to real-time pricing rates and loses flexibility
Solution Approach 1:
The patent implements dynamic power supply control by transitioning from static preset time slots to real-time rate-based control. The controller continuously monitors real-time pricing rates and dynamically adjusts power supply decisions, enabling the system to adapt to changing economic conditions while maintaining manageable complexity through automated comparison logic against preset references.
Solution Approach 2:
The system changes the control parameter from fixed time slots to variable real-time pricing rates. By comparing real-time rates against preset reference values, the system dynamically adjusts power supply parameters based on economic conditions, achieving adaptability without proportionally increasing system complexity.
2Productivity
If a single power meter serves one household, then metering is simple, but the system cannot efficiently manage power distribution across multiple consumers in multi-housing facilities
Solution Approach 1:
The patent makes the power supply control apparatus universal by enabling it to serve multiple consumers simultaneously. The controller can manage power distribution to multiple households or facilities through a single system, performing both centralized control and individual metering functions, thereby improving productivity without requiring separate meters for each consumer.
Solution Approach 2:
The system segments power distribution management by maintaining individual metering capabilities for each consumer while operating under unified real-time rate control. Each consumer's power usage is tracked separately, but all are managed through the same adaptive control logic, achieving efficient multi-consumer service with coordinated complexity.
3Ease of operation
If power supply is controlled only according to preset time slots, then the control mechanism is simple, but flexible conditions cannot be handled and adjustments are slow
Solution Approach 1:
The patent implements feedback control by continuously monitoring real-time pricing rates and automatically adjusting power supply decisions. The controller receives real-time rate information, compares it against preset references, and immediately adjusts power distribution accordingly, eliminating the time delay inherent in preset time slot systems and providing operational flexibility without increasing complexity.

AI summary
This specification relates to a power supply control apparatus. In order to solve problems of a power supply control only with respect to a preset time slot and difficulties in power supply to a plurality of consumers and metering of power supplied, which are the drawbacks of the related art electronic power meter, the power supply control apparatus can store or supply power according to a comparison result between a preset reference and a real-time pricing rate. Accordingly, electric charges, which are decided according to an amount of power used and reflect real-time rates thereto, can be saved and an appropriate power supply and an appropriate power reception of a consumer according to the real-time pricing rate can be allowed.
