Packing Box With Interlocking Blocking Portions For Stacked Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packing boxes for liquid crystal panels face challenges in enhancing anti-pressure capability without increasing the thickness of their walls, which affects the number of liquid crystal glasses that can be stacked, and existing solutions either increase weight or fail to enhance carrying capacity.
Innovation Solution
A packing box design featuring inward concave blocking portions with supporting members that form a screw connection through through holes and blind holes, along with a hollow middle and ribbed slabs, allowing for increased engagement precision and pressure distribution without increasing wall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of the walls of the blow-formed packing box is increased to enhance anti-pressure capability, then the carrying capability is improved, but the weight of the packing box increases
Solution Approach 1:
The box body is divided into multiple blocking portions (first, second, third, and fourth blocking portions) that segment the wall structure. These blocking portions are distributed at different locations on the box body to collectively enhance anti-pressure capability without requiring uniform wall thickening throughout the entire structure.
Solution Approach 2:
The blocking portions are strategically positioned at critical locations where pressure resistance is most needed. Each blocking portion has specific geometric features (such as the first blocking portion with area larger than the second, and the third larger than the fourth) to optimize local pressure distribution and resistance, achieving enhanced overall strength without increasing average wall thickness.
2Quantity of substance
If the thickness of the walls is increased to stack more liquid crystal glasses, then the carrying capability is improved, but the weight increases making transportation more difficult
Solution Approach 1:
The blocking portions are segmented and positioned to provide structural support for stacking multiple liquid crystal glasses. The segmentation allows the box to bear greater vertical loads without increasing overall wall thickness, enabling increased carrying capability while maintaining lightweight design.
Solution Approach 2:
The blocking portions with varying areas are strategically placed to optimize the distribution of vertical loads from stacked glasses. The larger blocking portions are positioned to handle greater loads, allowing the box to safely stack more items without requiring uniform wall thickening that would increase weight.

AI summary
A packing box is disclosed. The packing box includes a box body having an inward concave forming four blocking portions at four sides, and a plurality of supporting members. The supporting member includes a big head end and a small head end fixedly connecting to the blocking portions. The small head end is arranged above an up surface of the blocking portion. A bottom surface of the big head end comprises an inward concave, the small head end of the supporting member of the packing box located at a lower altitude engages with the big head end of the supporting member of the packing box located at a higher altitude when the packing boxes are stacked.
