Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If component exchange is performed to maintain or upgrade energy storage systems, then system adaptability and continued operation are improved, but safety risks and calibration complexity increase

Engineering Contradiction:

Improvecomponent exchange capabilityVSAvoidsafety requirement compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by acquiring feature data sets from exchanged components and comparing them with stored reference data before allowing full system operation. This preliminary verification process ensures safety requirements are met while enabling component exchange, resolving the contradiction between adaptability and reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring component feature data, comparing it with reference values, and adjusting system operation accordingly. When deviations are detected, the system can restrict functionality or alert operators, ensuring safety while allowing flexible component replacement.

Inventive Principle:

Principle #23Feedback

2Reliability

If complex calibration procedures are performed after component exchange to ensure safety, then system reliability is improved, but time loss and operational disruption increase

Engineering Contradiction:

Improvesafety verificationVSAvoidcalibration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs self-verification by automatically acquiring feature data from exchanged components, comparing it with stored reference data, and determining whether calibration is needed. This self-service approach eliminates the need for time-consuming manual calibration procedures while ensuring safety requirements are met, significantly reducing time loss.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical calibration procedures with electronic data comparison and analysis. Instead of performing time-consuming manual calibration, the system uses electronic feature data sets and automated comparison algorithms to verify component compatibility and safety, dramatically reducing calibration time while maintaining reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If component exchanges are restricted to maintain configuration integrity, then system reliability is improved, but adaptability and ease of maintenance deteriorate

Engineering Contradiction:

Improveconfiguration integrityVSAvoidcomponent exchange ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts its response to component exchanges based on real-time feature data comparison. Rather than imposing static restrictions, the system evaluates each exchanged component individually, allowing exchanges that meet safety criteria while restricting only those that compromise configuration integrity. This dynamic approach maintains reliability while facilitating ease of operation.

Inventive Principle:

Principle #15Dynamics

4Reliability

If feature data comparison and deviation classification are performed to enable informed operational decisions, then system reliability is improved, but device complexity and processing requirements increase

Engineering Contradiction:

Improveinformed operational controlVSAvoiddata processing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the feature data comparison process into distinct, manageable steps: acquiring feature data from components, comparing with reference data, classifying deviations, and making operational decisions. This segmentation reduces processing complexity by breaking down the complex task into modular, easily implementable steps while maintaining high reliability through systematic evaluation.

Inventive Principle:

Principle #1Segmentation

AI summary

A method for operating an electrical energy storage system, wherein the electrical energy storage system has a plurality of components which fulfill the same purpose, and the method comprises: acquiring first feature data sets that identify the components in each case unambiguously in the energy storage system; comparing the acquired first feature data sets with second feature data sets stored in a first memory; in the case of a deviation between the first feature data sets and the second feature data sets that is established by the comparison, classifying the deviation; storing a value in a second memory depending on the classification of the deviation; and upon a predefined condition being fulfilled by the stored value, at least partly limiting a functionality of the electrical energy storage system.
