Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Data processing systems with limited computing resources, storage capacity, and/or access to an uplink pathway face challenges in identifying and mitigating events impacting their operation, as they cannot efficiently manage commands to address potential future occurrences due to storage constraints and lack of communication with external entities.

Innovation Solution

A data processing system manager utilizes a digital twin to simulate the system's operation based on observational data, identifies relevant commands to mitigate future events, and manages the cache by updating it with commands that match future operating conditions, ensuring efficient storage usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the data processing system stores more commands to mitigate future events, then the reliability improves, but the storage capacity is exceeded

Engineering Contradiction:

Improveability to mitigate future eventsVSAvoidstorage capacity

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system performs preliminary actions by pre-identifying and storing commands that may be needed for future events before those events occur. The manager proactively determines which commands to store in advance based on predicted future operating conditions, allowing the data processing system to respond effectively when events actually happen without requiring excessive storage capacity at any single moment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter of command selection criteria dynamically. Instead of storing all possible commands, the manager adjusts the selection parameters based on predicted future operating conditions, storing only the subset of commands most likely to be needed. This adaptive parameter adjustment optimizes the balance between reliability and storage capacity utilization.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the data processing system accesses external entities for command guidance, then the reliability improves, but the access to uplink pathway is required which is limited

Engineering Contradiction:

Improveability to identify commands for future eventsVSAvoidaccess to uplink pathway

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The manager performs preliminary identification and selection of commands before the data processing system needs them. By proactively determining which commands to store in advance based on predicted future conditions, the system reduces the need for real-time external communication when events actually occur, thereby minimizing uplink pathway access requirements.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The data processing system becomes self-sufficient by having the manager pre-identify and store appropriate commands locally. The system no longer needs to continuously query external entities for command guidance, as the manager has autonomously determined and cached the necessary commands based on predicted operating conditions, enabling the system to serve itself when events occur.

Inventive Principle:

Principle #25Self-service

3Reliability

If the data processing system manages commands actively, then the reliability improves, but the computing resources are consumed

Engineering Contradiction:

Improveability to manage events effectivelyVSAvoidcomputing resources

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system changes the parameter of command management approach from reactive to proactive. Instead of consuming computing resources to actively monitor and respond to all possible events in real-time, the manager adjusts its operation mode to pre-identify and store commands based on predicted future conditions. This parameter change reduces ongoing computing resource consumption while maintaining effective event management capability.

AI summary

Methods and systems for managing operation of data processing systems with limited access to an uplink pathway are disclosed. To manage the operation, a system may include a data processing system manager, a data collector, and one or more data processing systems. The data processing system manager may identify future events that may impact operation of the data processing system using a digital twin and observational data. A cache hosted by the data processing system may store events and commands associated with the events. The commands may include action sets intended to mitigate impacts of the events. If the data processing system does not have commands associated with the simulated future events stored in the cache, the data processing system manager may provide instructions for replacing at least a portion of the commands stored in the cache with commands responsive to the simulated future events.
