Solution Overview

Problem

Existing energy storage battery cabinets face challenges with inconvenient installation due to one-side door opening, increased waterproof performance requirements, and increased depth, which complicates installation and increases costs.

Innovation Solution

The energy storage battery cabinet is designed with side doors that allow for left and right side opening, featuring a housing with a main body, side doors, and battery racks with support planes acting as slide rails for easy battery pack insertion, along with integrated sealing and waterproofing features to enhance safety and reduce installation complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If one-side door opening is used, then the cabinet structure is simple, but the installation convenience deteriorates and depth increases

Engineering Contradiction:
Improvecabinet structureVSAvoidinstallation convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The cabinet door is divided into two separate side doors instead of a single front door. Each side door can be opened independently, allowing installers to access the cabinet from either side. This segmentation resolves the contradiction by maintaining structural simplicity while significantly improving installation convenience through dual-access capability.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If one-side door opening is used, then the cabinet structure is simple, but the waterproof performance requirements increase

Engineering Contradiction:
Improvecabinet structureVSAvoidwaterproof performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

By dividing the single door into two side doors, the sealing structure is segmented into two separate sealing paths. Each side door has its own sealing ring and waterproof design, which reduces the overall sealing complexity compared to a large single door while maintaining or improving waterproof reliability through distributed sealing points.

Inventive Principle:
Principle #1Segmentation

3Reliability

If side doors with sealing rings are used, then the waterproof performance is improved, but the device complexity increases

Engineering Contradiction:
Improvewaterproof performanceVSAvoidcabinet structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing rings are implemented as flexible elastic sealing elements that can deform to accommodate manufacturing tolerances and assembly variations. This flexible sealing approach achieves reliable waterproof performance without requiring complex rigid sealing structures, thereby maintaining relative simplicity in the overall device design.

Inventive Principle:
Principle #30Flexible shells and thin films

4Ease of operation

If battery racks with support planes are used, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvebattery pack installationVSAvoidcabinet structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The battery rack is designed with support planes that automatically guide and position battery packs during installation. The support planes create natural stopping points and alignment features, allowing battery packs to be self-positioned without requiring complex alignment mechanisms or additional adjustment devices, thus improving ease of operation while maintaining structural simplicity.

Inventive Principle:
Principle #25Self-service
