Swingable Flap Holder for Carton Folding Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flap folding devices risk strong contact between the holding member and second flaps due to positional deviations, potentially causing bending or other issues.
Innovation Solution
A flap folding device with a swingable holding member that avoids strong contact by allowing it to pivot around an axis, preventing overlap and collision with second flaps, even when positional deviations occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding member is made fixed to press and hold the first flaps, then the holding member can stably hold the first flaps, but strong contact may occur with the second flap when positional deviation happens, causing bending or damage
Solution Approach 1:
The holding member is changed from a fixed structure to a swingable structure that can rotate around a rotation axis. This dynamic design allows the holding member to automatically adjust its position when contact with the second flap occurs, converting a potentially harmful fixed contact into a controllable rotational movement that prevents damage while maintaining holding function.
2Object-affected harmful factors
If the holding member is made swingable to avoid strong contact, then damage to the second flap is prevented, but the holding stability may be reduced
Solution Approach 1:
The swingable design with controlled rotation range maintains holding stability through the rotation mechanism. The holding member can swing within a defined range to avoid damage while still effectively pressing and holding the first flaps, achieving both protection and stability through controlled dynamic movement.

AI summary
A flap folding device includes a first member that folds a pair of first flaps toward an inside of an opening of a cardboard box, a second member that folds a pair of second flaps toward the inside of the opening, and a holding member including a rod-shaped or plate-shaped elongated portion extending along a long side direction of the opening, and pressing and holding the pair of folded first flaps by the elongated portion. The second member folds the pair of second flaps in a state where the pair of first flaps are held by the holding member after the first member folds the pair of first flaps. The holding member is attached to be swingable.
