Packaging Box Folded Inward Contact Flap Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging boxes face difficulties in efficiently inserting and retrieving packaged objects due to the placement of the folded inward contact flap, which can cause damage as it is often positioned near the center of the box, making it hard to visualize and resulting in interference with the object being packaged.
Innovation Solution
The packaging box design incorporates a folded inward contact flap with a projection and cutout hole mechanism that ensures the flap is positioned to be easily visible and contacts one of the side plates, preventing interference with the packaged object and enhancing visibility for easier insertion and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the folded inward contact flap is positioned near the center of the box, then the sealing function is improved, but the flap interferes with the packaged object and reduces visibility
Solution Approach 1:
The contact flap is repositioned from a central location to the lateral side of the box, utilizing the side dimension rather than the central space. This dimensional relocation allows the flap to maintain its sealing function while eliminating interference with packaged objects in the center of the box.
Solution Approach 2:
The holding mechanism acts as an intermediary between the contact flap and the second side plate, ensuring proper contact and sealing. This intermediary structure allows the flap to be positioned at the lateral side while still achieving reliable sealing through the holding mechanism's mediation.
2Reliability
If the folded inward contact flap is positioned near the center of the box, then the sealing function is improved, but the flap becomes difficult to visualize
Solution Approach 1:
The contact flap is relocated to the lateral side of the box, moving it to a more accessible dimension where it can be easily visualized and monitored during packaging operations, while still maintaining its sealing function.
Solution Approach 2:
The holding mechanism automatically ensures proper contact between the flap and the side plate through its mechanical design, making the sealing process self-regulating and easily observable without requiring complex monitoring systems.
3Ease of operation
If the folded inward contact flap is repositioned to the lateral side, then visibility and accessibility are improved, but the sealing effectiveness may be reduced
Solution Approach 1:
The holding mechanism serves as an intermediary that ensures effective sealing between the laterally positioned contact flap and the second side plate. This intermediary structure compensates for the repositioning by providing reliable mechanical contact and sealing pressure.
Solution Approach 2:
The holding mechanism modifies the contact parameters between the flap and side plate, ensuring adequate contact pressure and alignment. By adjusting these parameters, the sealing effectiveness is maintained despite the flap's repositioned location at the lateral side.

AI summary
A packaging box includes a first pair of side plates facing each other, a second pair of side plates facing each other, an upper plate to close an upper opening of the packaging box, a bottom plate to close a lower opening of the packaging box, a folded inward contact flap, and a holding mechanism. The folded inward contact flap is connected to a lateral side of one of the first pair of side plates and folded at the lateral side to be in contact with one of the second pair of side plates. The holding mechanism holds contact between the folded inward contact flap and the one of the second pair of side plates.
