Battery Pack Packaging Box With Foam Rib Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing high-capacity battery packs during transportation and handling result in damage to the external appearance due to friction and inadequate fixation in humid environments, leading to potential falls.
Innovation Solution
A battery pack packing box featuring a lower case with a buffering member that includes a frame and wing-shaped ribs to securely fix the battery pack through an insertion hole, utilizing materials like foam polystyrene or polypropylene to enhance friction and support the load, along with a seating member for stable seating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt is used to fix the battery pack, then the battery pack is secured during transportation, but the external appearance of the battery pack is damaged by friction
Solution Approach 1:
The patent introduces a buffering member made of foam material as an intermediary between the battery pack and the fixing structure. This buffering member has an insertion hole that receives the battery pack and provides friction-based fixation without direct contact between hard fixing elements and the battery pack surface, thereby preventing friction damage while maintaining reliable fixation
Solution Approach 2:
The buffering member utilizes the elastic properties of foam material to provide appropriate friction force for fixation. The foam material's inherent elasticity and deformability allow it to grip the battery pack securely through the insertion hole without exerting excessive localized pressure that would cause damage
2Ease of manufacture
If corrugated cardboard is used to fix the battery pack, then the structure is simple, but the battery pack falls down due to lack of fixation power in humid environments
Solution Approach 1:
The buffering member is made of foam material which provides superior mechanical properties compared to corrugated cardboard, including higher strength, better moisture resistance, and maintained fixation capability in humid environments. The foam structure combines ease of molding with reliable performance across different environmental conditions
3Quantity of substance
If more battery cells are included to increase capacity, then the energy density increases, but the weight and volume of the battery pack increase
Solution Approach 1:
The buffering member is designed with a modular structure including a frame and multiple wing-shaped ribs that can be configured to accommodate different battery pack sizes and capacities. This segmented design allows the fixing structure to be scaled and optimized for various battery configurations without requiring complete redesign
Solution Approach 2:
The foam buffering member acts as a flexible yet structurally sound container that adapts to the battery pack dimensions. The foam material provides cushioning and fixation while minimizing additional weight compared to rigid alternative materials
