Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each energy storage system is composed of an independent container unit, then each container can be independently controlled, but they cannot communicate or coordinate with other containers of the energy storage system

Engineering Contradiction:

Improveindependent control capabilityVSAvoidcommunication and coordination capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The energy storage system is divided into multiple independent container units, each with its own control container and battery container. This segmentation allows each unit to be independently controlled while maintaining overall system functionality through the master-slave controller architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The master controller in the control container acts as an intermediary that coordinates communication between multiple slave controllers in different battery containers. This mediator enables information exchange and coordinated control across independent container units, resolving the contradiction between independence and communication capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If a conventional container-unit energy storage system is used, then the system structure is simple, but it lacks efficient fire extinguishing mechanisms and communication stability

Engineering Contradiction:

Improvesystem structureVSAvoidfire extinguishing capability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system pre-installs fire extinguishing devices in each battery container and establishes communication protocols before failures occur. The master controller and slave controllers are pre-configured with communication pathways, and fire suppression systems are ready for immediate activation, enabling rapid response without adding operational complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The communication system provides continuous feedback between controllers and monitoring systems, enabling real-time detection of abnormal conditions. This feedback mechanism allows the system to maintain simple structure while achieving reliable fire extinguishing through automated monitoring and response protocols.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If multiple energy storage systems are provided as independent containers, then each system operates autonomously, but they require individual control and cannot be managed centrally

Engineering Contradiction:

Improveautonomous operationVSAvoidcontrol management structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Multiple independent container units are merged into a unified energy storage system through the master-slave controller architecture. The master controller combines control functions for multiple slave controllers, enabling centralized management while preserving the autonomous operation capability of individual containers through the hierarchical control structure.

Inventive Principle:

Principle #5Merging (Combining)
