Corrugated Fiberboard Packing Box with Integral Corner Columns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packing devices with columns between upper and lower corrugated fiberboards increase component count, assembly time, and costs, and the corrugated fiberboard boxes with corner columns are cumbersome and costly to use.
Innovation Solution
A packing box formed by a single corrugated fiberboard sheet with a rectangular bottom plate, side plates, and frame columns at the corners, where the frame columns are erected from the bottom plate side and extend to the midway of the side plates, joined using through holes and a joining member, providing improved compression strength and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If columns are inserted between upper and lower corrugated fiberboards to support the product, then product protection during transportation is improved, but the number of components increases and assembly time increases
Solution Approach 1:
The patent combines the column support structure with the corrugated fiberboard itself by forming integral columns as extensions of the fiberboard panels. This eliminates separate column components while maintaining the protective support function, directly resolving the contradiction between product protection and component complexity
Solution Approach 2:
The corrugated fiberboard serves multiple functions simultaneously: it provides the main packaging structure, forms protective columns at corners and edges, and creates the overall protective enclosure. This multi-functionality eliminates the need for separate column components while maintaining comprehensive product protection
2Reliability
If columns are inserted between upper and lower corrugated fiberboards to support the product, then product protection during transportation is improved, but assembly time increases
Solution Approach 1:
The column structures are pre-formed as integral parts of the corrugated fiberboard panels during manufacturing. When assembly occurs, the columns are already in place and require no separate assembly steps, eliminating assembly time while maintaining product protection
Solution Approach 2:
By merging the column structure with the fiberboard panels, the patent eliminates separate assembly operations for columns. The integrated design allows the packaging to be assembled as a single unit, directly reducing assembly time while preserving protective functionality
3Shape
If corner columns are disposed at four corners of the box by tucking in extension parts, then the box shape is formed, but the box size becomes large and requires more work to put/take product in/out
Solution Approach 1:
The patent applies reinforcement selectively only at the corner regions where columns are formed, rather than creating a bulky overall structure. This localized approach maintains the box's compact dimensions while providing necessary structural support, preserving ease of product handling
Solution Approach 2:
Instead of extending the overall box size to accommodate corner columns as separate protruding elements, the patent inverts the approach by forming columns inward from the corner edges. This creates the necessary structural support without increasing the external box dimensions, maintaining ease of product insertion and removal
4Reliability
If corner columns are disposed at four corners of the box, then product containment is improved, but cost increases
Solution Approach 1:
The patent merges the column structures with the corrugated fiberboard panels, eliminating the need for separate column materials and assembly operations. This integration reduces material costs and manufacturing complexity while maintaining effective product containment through the integrated corner and edge support structures

AI summary
A packing box comprising a rectangular bottom plate 1 and a plurality of side plates 2 and 3 erected from the periphery of the bottom plate 1 and surrounding the bottom plate 1, in which at four corners in corner parts formed by the plurality of side plates 2 and 3, frame columns 14, each erected from the bottom plate 1 side and extending to the midway to a distal end of the side plates 2 and 3, are formed and joined to the side plates 2 and 3, and the bottom plate 1, the side plates 2 and 3, and the frame columns 14 are formed by one corrugated fiberboard sheet.
