Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If distributed battery systems are deployed at consumer premises, then local electricity management and demand management services are improved, but costs and life-cycle limits worsen

Engineering Contradiction:
Improvelocal electricity managementVSAvoidcosts
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent combines multiple functions into a single distributed battery system unit: power storage, DC power supply, demand monitoring hub, and communication capabilities. This integration reduces overall system costs and simplifies deployment at consumer premises while maintaining comprehensive local electricity management functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The distributed battery system is designed to perform multiple functions simultaneously: it provides local DC power supply, monitors demand, communicates with the grid, and participates in aggregate grid storage services. This multi-functionality maximizes the utility of each deployed unit, improving ease of operation while optimizing cost-effectiveness through versatile resource utilization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If distributed battery systems are deployed at consumer premises, then demand management services are improved, but lack of smart management solutions worsens deployment effectiveness

Engineering Contradiction:
