Solution Overview

Problem

Existing power control systems struggle to finely manage power supply to multiple power-consuming devices when necessary power is insufficient, lacking control mechanisms to prevent excessive electricity usage and sudden ampere breaker tripping.

Innovation Solution

A power control device that predicts total consumed power values and controls power supply by transmitting operation control signals to power-consuming devices, allowing for fine-tuned power reduction or shutdown, and includes a power generation facility to supplement power when needed, using a packet structure for efficient power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If power control systems manage multiple power-consuming devices, then power distribution capability is improved, but control precision deteriorates due to inability to finely manage individual device power supply

Engineering Contradiction:
Improvepower distribution capabilityVSAvoidcontrol precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system segments power control into two levels: macro-level power packet routing to groups of devices, and micro-level individual device control through operation control signals. This segmentation enables both versatile power distribution and precise individual device management simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power control device acts as an intermediary between the power supply and multiple power-consuming devices. It receives power packets, determines distribution amounts, and transmits both power and operation control signals to individual devices, enabling fine-grained control while managing multiple devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If power supply control is implemented without prediction, then system simplicity is improved, but reliability deteriorates due to excessive electricity usage and ampere breaker tripping

Engineering Contradiction:
Improvesystem simplicityVSAvoidpower supply stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs preliminary power consumption prediction before actual power distribution. By predicting total power consumption of multiple devices and comparing it with available power packet amounts, the system proactively determines distribution amounts to prevent excessive usage and breaker tripping, ensuring reliable power supply.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If power packets are supplied without individual device control, then power transmission efficiency is improved, but power management capability deteriorates due to lack of control when necessary power is insufficient

Engineering Contradiction:
Improvepower transmission efficiencyVSAvoidpower management capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The power control device serves as an intermediary that receives power packets efficiently and simultaneously manages individual device control. It determines distribution amounts based on predicted consumption and transmits both power and operation control signals, maintaining transmission efficiency while enabling precise power management.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback control by monitoring actual power consumption of individual devices and comparing it with predicted values. Based on this feedback, the power control device adjusts operation control signals to optimize power distribution, ensuring both efficient transmission and adaptive management.

Inventive Principle:
Principle #23Feedback
