Solution Overview

Problem

The existing energy storage cabinets face risks of fire accidents due to thermal runaway of batteries during storage and transportation, as the separator can be damaged, leading to short circuits and high-temperature chemical reactions, which can ignite combustible materials and damage adjacent devices.

Innovation Solution

A cabinet unit and system design featuring extruded side walls with fitting pieces that snap fit together, forming a secure and airtight interface, and a concrete body with synthetic fibers for enhanced strength and thermal insulation, combined with a flame-resistant material layer to contain and mitigate high temperatures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional metal containers are used for energy storage cabinets, then structural strength and fire resistance are improved, but weight and assembly complexity increase

Engineering Contradiction:

Improvestructural strengthVSAvoidcabinet weight

Core Design Contradiction:

StrengthVSWeight of stationary object

Solution Approach 1:

The cabinet is divided into multiple modular units that can be assembled together. Each unit has standardized connection interfaces (fitting pieces) that enable easy assembly and disassembly. This segmentation allows the use of lighter materials while maintaining overall structural integrity through the modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses composite material construction for the cabinet body, combining different materials to achieve both strength and weight reduction. The side walls use extruded profiles with fitting pieces that provide structural strength while being lighter than solid metal containers.

Inventive Principle:

Principle #40Composite materials

2Strength

If traditional metal containers are used for energy storage cabinets, then structural strength is improved, but ease of assembly and transportation are worsened

Engineering Contradiction:

Improvestructural strengthVSAvoidease of assembly

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection system uses movable and adjustable fitting pieces that can be easily engaged and disengaged. The extruded side walls incorporate connection structures that allow for dynamic assembly during installation and easy disassembly for transportation or reconfiguration.

Inventive Principle:

Principle #15Dynamics

3Reliability

If traditional metal containers are used for energy storage cabinets, then durability is improved, but adaptability and flexibility are worsened

Engineering Contradiction:

ImprovedurabilityVSAvoidadaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The standardized fitting pieces and extruded side wall design create universal interfaces that can accommodate different cabinet configurations. This universality allows the same basic unit to be adapted for various applications and scaled from single units to multiple-unit systems, enhancing both adaptability and flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If battery energy storage equipment is stored in metal containers, then protection is provided, but fire propagation risk increases due to thermal runaway

Engineering Contradiction:

ImproveprotectionVSAvoidfire propagation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The extruded side walls with fitting pieces act as intermediary structures between adjacent battery units. These connection structures incorporate thermal insulation and fire-resistant materials that serve as barriers to prevent fire propagation while maintaining structural protection.

Inventive Principle:

Principle #24Intermediary (Mediator)
