Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a unique design is developed for each different smart grid node, then the node can meet its specific operation and design requirements, but the device complexity and development effort increase significantly

Engineering Contradiction:
Improvenode-specific functionalityVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal processor platform that can execute different software images to control various smart grid node types (meters, gateways, relays). This single hardware platform performs multiple functions by loading appropriate software, eliminating the need for unique hardware designs for each node type while maintaining node-specific functionality through software configuration.

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

Solution Approach 2:

The system uses software images with configurable parameters to adapt the universal processor to different node requirements. By changing software parameters and configuration settings rather than hardware design, the system meets specific operation requirements for different nodes without increasing hardware complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple unique hardware devices are designed for different smart grid nodes, then each node's specific requirements are met, but the development and verification effort increases considerably

Engineering Contradiction:
Improvenode type coverageVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

A single universal processor design serves multiple node types by executing different software images. This approach covers all node types (meters, gateways, relays) without requiring separate development cycles for each hardware device, significantly reducing development time while maintaining node type coverage.

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

Solution Approach 2:

The system uses software images as copies of control logic that can be loaded onto the universal processor. Instead of developing unique hardware for each node type, the invention creates software copies that replicate the required functionality on a standardized hardware platform, reducing development effort.

Inventive Principle:
Principle #26Copying

3Device complexity

If standardized hardware is used for all smart grid nodes, then design complexity is reduced, but the ability to meet specific operation requirements of different networks and nodes is compromised

Engineering Contradiction:
Improvehardware complexityVSAvoidnetwork compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The universal processor hardware provides a standardized platform that maintains low hardware complexity while achieving network compatibility through software. The system can operate in different networks (mesh, star, hybrid) and support various node types by loading appropriate software images with network-specific configurations.

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

Solution Approach 2:

The system dynamically adapts to different network requirements through software configuration rather than static hardware design. The processor can change its behavior and functionality by loading different software images tailored to specific network topologies and operational requirements, maintaining both simplicity and adaptability.

Inventive Principle:
Principle #15Dynamics
