Packaging Box for Liquid Crystal Glass with Segmented Buffer Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging methods for liquid crystal glass are costly due to the use of expensive expanded materials like EPP, EPE, and EPS, which are necessary for effective buffering but increase packaging costs.
Innovation Solution
A packaging box made of ABS or HDPE with EPP buffer blocks provides superior buffering performance at a lower cost by using a separated structure with injection-molded L-shaped clamping arms and integrated buffer springs for secure fixation and enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expanded materials (EPP, EPE, EPS) are used for packaging liquid crystal glass, then buffer performance and protection are improved, but packaging cost increases
Solution Approach 1:
The packaging box is divided into two functional parts: the box body (made of ABS or HDPE) and the buffer blocks (made of EPP). This segmentation allows each part to be optimized independently - the box body provides structural strength at lower cost, while the buffer blocks provide superior cushioning performance where needed.
Solution Approach 2:
EPP buffer blocks are placed specifically at the four corners and middle parts of the box body where impact and friction occur most frequently. This localized application of high-performance buffering material provides maximum protection at minimum cost, rather than using expensive expanded material throughout the entire packaging structure.
2Reliability
If expanded materials are used for the entire packaging box, then buffer performance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The packaging system is segmented into a simple box body structure and separate buffer block components. This allows the box body to be manufactured using straightforward injection molding processes, while the buffer blocks are added as separate elements that provide the complex buffering function only where required.
Solution Approach 2:
The buffering function is extracted from the box body material itself and separated into distinct buffer block components. This extraction allows the box body to be made from simpler, less expensive materials while the buffering performance is provided by specialized EPP blocks placed at critical locations.

AI summary
The invention relates to the field of packaging, and more particularly to a packaging box for liquid crystal glass. The packaging box for liquid crystal glass includes a box body; the box body is internally provided with buffer blocks which are made of material different from that of the box body and have buffer performance superior to that of the box body. The packaging box for liquid crystal glass of the invention is of a separated structure, the box body and the buffer blocks are respectively made of different materials, the buffer blocks are made of material with good buffer performance, and the box body is mainly used for fixing the buffer blocks and ensuring the strength of the whole box body; thus, the box body is made of ordinary plastic material and injection molded without being made of expanded buffer material with buffer effect and high cost, thereby reducing the cost of the packaging box.
