Solution Overview

Problem

Existing electrical power distribution systems face challenges in ensuring continuous operation of critical sub-systems during primary power source outages or surges, as they lack efficient prioritization and power management strategies to optimize backup power usage.

Innovation Solution

A power management system that receives sensor data and parameter sets for sub-systems to control the distribution of electrical power from primary and secondary sources, prioritizing critical sub-systems and adjusting power consumption based on heat dissipation and temperature requirements, thereby extending runtime during backup power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If backup electrical power is distributed to all sub-systems simultaneously, then all sub-systems can operate during outage, but the backup power source depletes quickly and cannot sustain operation

Engineering Contradiction:
Improvecontinuous operation of sub-systemsVSAvoidruntime of backup power source
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent segments the sub-systems into different priority groups (critical, important, non-critical) and distributes backup power selectively rather than uniformly to all sub-systems. This segmentation allows the limited backup power to sustain critical sub-systems for extended periods while non-critical sub-systems are powered down or operated at reduced capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by providing different power distribution characteristics to different sub-systems based on their specific requirements and priorities. Critical sub-systems receive full power allocation, while non-critical sub-systems receive reduced or no power allocation, optimizing the overall runtime of the backup power source.

Inventive Principle:
Principle #3Local quality

2Duration of action of moving object

If power management system controls and reduces electrical power consumption by sub-systems, then runtime under backup power is increased, but some sub-systems may not receive sufficient power for optimal operation

Engineering Contradiction:
Improveruntime under backup powerVSAvoidoperation continuity of sub-systems
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent implements dynamic power management where the power allocation to each sub-system is not fixed but can be adjusted in real-time based on current operational needs, battery charge levels, and priority rankings. The system can dynamically shift power allocation between sub-systems and adjust operational parameters to maintain critical functions while extending overall runtime.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes operational parameters of sub-systems (such as reducing processing speed, lowering temperature thresholds, or putting non-critical sub-systems into sleep mode) to reduce power consumption while maintaining essential functions. This allows the system to extend runtime without completely sacrificing operational reliability of critical functions.

Inventive Principle:
Principle #35Parameter changes

AI summary

In an example method, a power management system receives sensor data regarding an operation of a primary power source, a secondary power source, an environmental regulation system, and a plurality of electrically-powered sub-systems. Further, the system receives a plurality of parameter sets for the sub-systems, each including a first parameter indicting a priority of a respective sub-system relative to the other sub-systems, a second parameter indicating an amount of heat dissipated by the respective sub-system during operation, and a third parameter indicating a temperature requirement associated with the respective sub-system. The system controls, based on the sensor data and the parameter sets, a delivery of electrical power from the primary and secondary power sources to the environmental regulation system and the sub-systems. Further, the system controls, based on the sensor data and the parameter sets, a consumption of electrical power by the environmental regulation system and the sub-systems.
