Solution Overview

Problem

Existing containers for energy storage apparatuses waste space due to overlapping support frames and side frames, limiting spatial utilization and efficiency.

Innovation Solution

The container integrates support frames on the upper and lower plates with vertically coupled frames, eliminating unnecessary overlaps and optimizing space usage by forming a unified battery rack configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If support frames are made separately and battery racks are coupled to the container, then the battery rack can be assembled as a finished product, but the lower end of the battery rack and side frame overlap, wasting space

Engineering Contradiction:
Improvebattery rack assemblyVSAvoidspatial utilization
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The patent merges the support frames with the container body by integrally coupling them, eliminating the separate assembly step. The support frames are formed as one piece with the container walls, which removes the overlapping issue between battery rack lower ends and side frames, thereby improving spatial utilization while maintaining manufacturing feasibility through integral forming processes

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate support frames and vertical frames are used, then the structure can be assembled from components, but frame duplication occurs and space is wasted

Engineering Contradiction:
Improvestructural configurationVSAvoidspace utilization
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines support frames and vertical frames into a single integrated structure that is formed as one piece with the container. This integration eliminates frame duplication and overlapping, maximizing the usable internal space while maintaining the necessary structural configuration for battery rack installation through the unified frame design

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If more frames are installed to support battery racks, then structural stability is improved, but space utilization decreases due to frame overlap

Engineering Contradiction:
Improvestructural stabilityVSAvoidinternal space
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent integrates multiple frame functions into a single unified structure that is formed as one piece with the container. This integrated frame structure provides the necessary structural stability for supporting battery racks while eliminating the space-wasting overlaps that occur when separate frames are assembled, thereby maintaining stability with optimized space utilization

Inventive Principle:
Principle #5Merging (Combining)
