Battery Pack Packaging Box With Ribbed Buffering for Secure Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for packaging high-capacity battery packs, such as using belts or corrugated cardboard, often damage the pack's appearance and fail to provide sufficient fixation, especially in humid environments, leading to movement and potential damage during transportation and handling.
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, utilizing materials like foam polystyrene, polypropylene, or polyethylene to absorb shocks and prevent movement, along with a seating member for stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
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 as an intermediary between the battery pack and the packing box. This buffering member has a hollow structure that contacts the battery pack surface, eliminating direct friction from belts while maintaining fixation stability through the cushioning structure.
Solution Approach 2:
The buffering member is designed as a flexible hollow structure that can deform to accommodate the battery pack while providing gentle contact. This flexible shell structure secures the battery pack without the concentrated friction pressure that damages surfaces.
2Ease of manufacture
If corrugated cardboard is used to fix the battery pack, then the structure is simple and成本低, but the battery pack falls down due to lack of fixation power in humid environments
Solution Approach 1:
The buffering member is made from composite materials such as foam polystyrene, foam polypropylene, or foam polyethylene. These composite materials maintain their structural integrity and fixation power in humid environments unlike corrugated cardboard, while still being relatively easy to manufacture.
Solution Approach 2:
The buffering member features localized structural qualities with thickened ribs at critical contact points and a hollow structure in non-critical areas. This provides high fixation reliability where needed while maintaining overall manufacturing simplicity and cost-effectiveness.
3Quantity of substance
If more battery cells are included to secure high capacity, then the energy density increases, but the battery pack becomes heavier and more difficult to handle
Solution Approach 1:
The buffering member provides beforehand cushioning that distributes the weight of high-capacity battery packs across multiple contact points. The hollow structure and rib design create a weight-distributing framework that makes handling easier while accommodating increased battery capacity.
Solution Approach 2:
The buffering member introduces a three-dimensional hollow structure with vertical ribs that provide support in multiple dimensions. This dimensional approach to weight distribution allows the battery pack to maintain high capacity while reducing the effort required for handling through spatial load distribution.
