Solution Overview

Problem

Existing systems for managing electric power consumption fail to proactively optimize device operations to meet global power consumption preferences and local constraints, leading to peak consumption issues and inefficiencies.

Innovation Solution

A system and method that allows user devices to communicate and coordinate their power consumption plans with smart meters and energy suppliers, adjusting deferred start times and energy consumption profiles to distribute power usage evenly and comply with maximum power limits, thereby optimizing energy delivery and avoiding peak consumption periods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If devices are instructed to cease energy consumption entirely, then global power consumption preferences are met, but programmed tasks may not be executed

Engineering Contradiction:
Improvepower consumptionVSAvoidtask execution
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system dynamically adjusts the operation state of devices between active and standby modes based on real-time power consumption targets and task progress, rather than using fixed cease-or-execute instructions. This allows flexible adaptation to meet power preferences while ensuring task completion.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements continuous feedback loops where device controllers report task progress and power consumption status to the energy management system, which then adjusts operational instructions accordingly. This ensures that power reduction actions do not compromise task execution reliability.

Inventive Principle:
Principle #23Feedback

2Use of energy by stationary object

If all devices programmed with deferred start run at the same time when a tariff change signal arrives, then optimum tariff conditions are achieved, but peak consumption is created

Engineering Contradiction:
Improvetariff optimizationVSAvoidpeak consumption
Core Design Contradiction:
Use of energy by stationary objectVSPower

Solution Approach 1:

The system segments the simultaneous start-up of multiple devices into staggered time slots, distributing the power demand across different time intervals rather than allowing all devices to start simultaneously. This eliminates peak consumption while maintaining tariff optimization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary scheduling and coordination of device start times before the actual tariff change occurs, pre-calculating optimal start times that distribute load and avoid peaks while still capturing tariff benefits.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If devices operate without proactive management, then local electric power use constraints are simplified, but global power consumption preferences are not met

Engineering Contradiction:
Improveoperational simplicityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

Devices are equipped with embedded controllers that automatically receive and execute power management instructions from the energy management system without requiring user intervention. This maintains operational simplicity for users while enabling sophisticated global power consumption management.

Inventive Principle:
Principle #25Self-service
