Solution Overview

Problem

The installation and positioning of heavy-duty battery racks are challenging due to difficulties in precise alignment and stabilization during transportation and placement, leading to uneven arrangements and potential issues with electrical connections.

Innovation Solution

The battery rack design incorporates fixing grooves in the front and rear frames, allowing for stable fixation to the bottom and transport devices, ensuring secure positioning even under external impacts, and facilitating easy installation through bolt insertion and tightening mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If transportation equipment is used to move heavy battery racks, then the battery rack can be transported to the installation site, but it becomes difficult to precisely adjust the position of the battery rack

Engineering Contradiction:
Improvebattery rack weightVSAvoidpositioning precision
Core Design Contradiction:
Weight of moving objectVSMeasurement precision

Solution Approach 1:

The patent incorporates fixing grooves and adjustment mechanisms into the battery rack structure before transportation. These pre-installed features enable precise positioning at the installation site without requiring complex adjustments after the heavy rack is delivered, thus resolving the contradiction between heavy weight and positioning precision.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If the battery rack is designed to accommodate heavy load, then the capacity increases, but the difficulty of accurate positioning at the fixing point increases

Engineering Contradiction:
Improvebattery capacityVSAvoidinstallation ease
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The battery rack is divided into modular sections with standardized fixing grooves and connection points. This segmentation allows the heavy-capacity rack to be assembled and positioned more easily, as each module can be independently handled and precisely aligned before being combined into the complete high-capacity system.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the battery rack arrangement is uneven, then the installation process becomes faster, but the electrical connection between battery racks becomes problematic

Engineering Contradiction:
Improveinstallation speedVSAvoidelectrical connection reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces standardized fixing grooves and alignment features as intermediary elements between the battery rack and the installation surface. These intermediaries ensure that even when installed quickly, the racks maintain precise alignment and proper spacing, thereby ensuring reliable electrical connections without compromising installation speed.

Inventive Principle:
Principle #24Intermediary (Mediator)
