Solution Overview

Problem

The uneven coating of heat-conducting glue between the water-cooled plate and battery module in power batteries results in poor heat dissipation performance due to lack of uniform glue distribution, leading to inefficient heat transfer.

Innovation Solution

A module pressurization device with a jacking and supporting mechanism and pressurization mechanism that separates the battery module from the conveying line, applies uniform pressure to the heat-conducting glue, and ensures consistent coating through controlled jacking and supporting portions and pressurization assemblies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the battery module is pressed during heat-conducting glue coating, then the glue can be spread uniformly, but the conveying line may be pressed and cause operational instability

Engineering Contradiction:
Improveuniformity of heat-conducting glue coatingVSAvoidstability of conveying line operation
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent introduces a jacking and supporting mechanism as an intermediary device between the pressurization mechanism and the battery module. This mechanism includes multiple jacking and supporting portions that are arranged to provide distributed support points, effectively transferring and distributing the pressing force from the pressurization mechanism to prevent localized deformation of the heat dissipation plate while maintaining uniform glue coating. The intermediary mechanism thus protects the conveying line from direct pressing forces.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If multiple jacking and supporting portions are used to prevent heat dissipation plate deformation, then the supporting force is distributed uniformly, but the device complexity increases

Engineering Contradiction:
Improveprevention of heat dissipation plate deformationVSAvoidnumber of jacking and supporting portions
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The jacking and supporting mechanism is segmented into multiple independent jacking and supporting portions arranged in an array. Each portion functions as an independent support element that can be positioned at specific locations corresponding to the heat dissipation plate structure. This segmentation allows the mechanism to provide distributed supporting force across multiple points, effectively preventing localized deformation of the heat dissipation plate during pressurization while maintaining a relatively simple overall structure through modular design.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the battery module is separated from the conveying line during pressurization, then the conveying line stability is maintained, but the production efficiency may be reduced due to additional separation and reattachment steps

Engineering Contradiction:
Improvestability of conveying line during pressurizationVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent employs a dynamic pressurization system where the pressurization mechanism and jacking and supporting mechanism are controllably activated and deactivated based on production cycle requirements. During pressurization operations, the mechanism dynamically separates the battery module from the conveying line to ensure stability and prevent deformation. Between operations, the system dynamically returns to a connected state for efficient conveying. This dynamic control optimizes both conveying line stability during pressurization and production efficiency during transport phases.

Inventive Principle:
Principle #15Dynamics
