Cardboard Box Assembly Device Offset Flap Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard box assembly devices fail to properly engage flaps when their positions are offset from normal, leading to misalignment and ineffective assembly.
Innovation Solution
A cardboard box assembly device comprising a folding unit, a pushing unit, and a drive unit that folds and positions flaps to ensure engagement, even when offset, by imparting a prescribed displacement to the cardboard box, allowing the locking flap to move relative to other flaps and correct positional offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second bottom face piece is pushed inside the packaging box to engage the projection with the recess, then the bottom face is assembled, but if positions of the recess and projection are offset, the engagement fails
Solution Approach 1:
The patent introduces a drive unit that imparts prescribed displacement to the cardboard box, making the positioning dynamic rather than static. This allows the system to adjust for positional offsets between the recess and projection by moving the box to the correct position before engagement, rather than requiring precise initial positioning.
Solution Approach 2:
The drive unit performs preliminary positioning of the cardboard box before the pushing unit engages the second bottom face piece. By pre-adjusting the box position to ensure proper alignment between the recess and projection, the system prevents engagement failure before it occurs.
2Ease of manufacture
If the folding unit folds four flaps in sequence to close the opening, then the box structure is formed, but the locking flap may not align properly with other flaps due to positional offset
Solution Approach 1:
The system uses dynamic positioning through the drive unit to adjust the cardboard box position during the folding process. This allows the locking flap to be positioned correctly relative to other flaps even when initial positions are offset, maintaining ease of manufacture while improving alignment precision.
Solution Approach 2:
The system incorporates feedback by monitoring the position of flaps during folding and using the drive unit to impart corrective displacement to the cardboard box. This feedback mechanism ensures proper alignment of the locking flap with other flaps despite initial positional variations.

AI summary
A cardboard box assembly device, that folds four flaps provided at edges of an opening in a cardboard box to surround the opening, is disclosed. The cardboard box assembly device includes a folding unit, a pushing unit, and a drive unit. The folding unit folds each of the four flaps in a prescribed sequence and closes the opening. The pushing unit pushes one of the four flaps, that is folded last, inward into the cardboard box as a locking flap, and overlaps the locking flap onto the other flaps. The drive unit contacts the cardboard box and imparts a prescribed displacement to the cardboard box. Parts that engage with one another are formed between the locking flap and at least one of the other flaps. The drive unit moves the locking flap relative to the other flaps due to the displacement when the pushing unit pushes the locking flap.
