Packaging Box Reinforcing Member for Liquid Crystal Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing packaging structures for liquid crystal panels are costly due to the use of expensive foaming materials like expandable polyethylene and expanded polypropylene, and they do not efficiently manage the supporting strength for larger panels.
Innovation Solution
A packaging box design featuring a reinforcing member fixed to the bottom board with position-limited grooves and locking members, which enhances the supporting strength of the bottom board while reducing the overall thickness of the box, allowing for more efficient stacking and logistics warehousing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foaming materials (EPE, EPP) are used to cushion and protect the liquid crystal panel, then the protective performance is improved, but the packaging cost increases
Solution Approach 1:
The invention extracts the cushioning function from the traditional foaming material tray and relocates it to independent cushioning structures (first and second cushioning members) positioned at specific locations where the liquid crystal panel contacts the packaging box, eliminating the need for expensive EPE/EPP materials throughout the entire tray structure
Solution Approach 2:
The invention replaces expensive foaming materials with cheaper alternative materials for the cushioning members, achieving the same protective function at lower cost. The cushioning members are designed as simple, disposable components that can be easily replaced
2Strength
If the glass-loading surface is made thicker with reinforcing structures to protect the liquid crystal panel during transport, then the protective strength is improved, but the packaging box size and material consumption increase
Solution Approach 1:
The invention applies reinforcement only at specific locations where the liquid crystal panel contacts the packaging box (at the four corners and midpoints of the four sides), rather than uniformly thickening the entire glass-loading surface. This localized reinforcement approach maintains protective strength while minimizing material consumption and box size
Solution Approach 2:
The reinforcing structure is divided into multiple independent reinforcing members positioned at specific locations, rather than using a single continuous thick structure. This segmentation allows reinforcement only where needed, reducing overall material consumption
3Reliability
If the packaging box uses more materials and thicker structures to ensure protection, then the protective performance is improved, but the logistics warehousing space increases
Solution Approach 1:
The invention provides protection only at the critical contact points between the liquid crystal panel and the packaging box, rather than uniformly thickening the entire box structure. This localized approach maintains protective performance while minimizing the overall box dimensions and warehousing space requirements

AI summary
A packaging box for a liquid crystal panel includes a box and a reinforcing member, the box includes a bottom board and a side frame, and the reinforcing member is fixed on the bottom board. Since the reinforcing member is fixed on the bottom of the box, the supporting strength of the bottom board is enhanced. Thus, the thickness of the box is decreased, which is advantageous to decrease the thickness of the whole stacked pallet and warehousing spaces of logistics.
