Solution Overview

Problem

The increasing demand for electrical capacity in energy storage containers leads to larger volumes, which often exceed space restrictions during transportation, necessitating excessive installation space that enlarges the container size and occupies excessive space.

Innovation Solution

The energy storage container design includes recessed corner posts to accommodate battery racks, avoiding interference and maintaining compactness by integrating battery packs without enlarging the frame, along with features like recessed spaces for pipelines and hinges to optimize space utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the number of battery packs and auxiliary components is increased to meet electrical capacity demand, then the electrical capacity is improved, but the total volume of the energy storage system increases

Engineering Contradiction:
Improveelectrical capacityVSAvoidtotal volume
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The patent applies nesting by placing battery racks inside recessed spaces formed within the corner posts of the frame. The corner posts are designed with inward recesses that accommodate battery racks, allowing the battery packs to be nested within the structural elements of the frame itself, thereby utilizing otherwise wasted space and reducing the overall external volume of the energy storage system.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent utilizes the vertical dimension by designing corner posts that extend along the gravity direction with recessed portions. This vertical integration allows battery racks to be positioned in three-dimensional space within the corner posts, transforming a two-dimensional surface structure into a three-dimensional space-utilizing design that reduces the horizontal footprint and total volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If installation space is provided to avoid interference between components, then the ease of installation is improved, but the volume of the energy storage container increases

Engineering Contradiction:
Improveease of installationVSAvoidvolume of container
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent merges the installation space with the structural elements of the frame. The corner posts are designed to integrate battery rack mounting functions directly into their structure, eliminating the need for separate installation spaces. The recessed portions of the corner posts serve dual purposes: maintaining structural integrity and providing built-in mounting areas for battery racks, thereby avoiding additional volume increase.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies local quality by creating recessed portions specifically at the corner posts where battery racks need to be installed. This localized modification provides necessary installation space and avoids interference between components only at the critical locations, rather than increasing the overall container volume uniformly throughout the entire structure.

Inventive Principle:
Principle #3Local quality
