Solution Overview

Problem

Existing power control systems for machines face inefficiencies and machine downtime due to inadequate distribution of power from sources to powered devices, leading to potential power source failures and decreased performance.

Innovation Solution

A control system that includes power generation, transformation, and distribution modules, along with a processor to determine available power, prioritize power requests, and adjust operating conditions of the power generation system to intelligently distribute power to devices based on their importance and requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If power is distributed to multiple powered devices simultaneously, then more devices can operate, but power source failures occur when demand exceeds supply

Engineering Contradiction:
Improvenumber of operating devicesVSAvoidpower source stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The control system continuously monitors power availability from the power source and adjusts power distribution to individual devices based on real-time feedback. When the power source cannot meet total demand, the system dynamically reduces power to lower-priority devices while maintaining operation of higher-priority devices, preventing power source failures while maximizing the number of operating devices.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system assigns different priority levels to different powered devices, creating local quality differences in power allocation. High-priority devices receive guaranteed power supply while low-priority devices receive power only when available, allowing the system to operate more devices simultaneously without compromising power source reliability.

Inventive Principle:
Principle #3Local quality

2Reliability

If power requests are reduced to prevent failures, then power source reliability improves, but device performance decreases

Engineering Contradiction:
Improvepower source stabilityVSAvoiddevice performance
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts power distribution based on changing conditions rather than using fixed allocations. When power availability increases or device priorities change, the system automatically reallocates power to maintain optimal device performance while preventing power source failures, resolving the contradiction between reliability and productivity.

Inventive Principle:
Principle #15Dynamics

3Reliability

If intelligent power distribution is implemented, then power source failures are reduced, but system complexity increases

Engineering Contradiction:
Improvepower source stabilityVSAvoidcontrol system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control system automatically monitors power availability and makes distribution decisions without requiring external intervention or complex manual control. The system serves itself by continuously adjusting power allocation based on real-time conditions, reducing power failures while keeping the control architecture relatively simple through autonomous operation.

Inventive Principle:
Principle #25Self-service

AI summary

A method for distributing power generated by a power generation system may include determining available power that can be generated by the power generation system. The method may also include obtaining power requests from power transforming devices, comparing the available power to the power requests, and determining amounts of the available power to distribute to the power transforming devices. The method may further include obtaining operating condition requests from the power transforming devices, and determining the operating conditions under which the power generation system should operate.
