T-Shaped Box Closure Device With Angled Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for closing and sealing corrugated boxes, such as regular slotted cartons, are cumbersome and inefficient, especially for hand-held devices, which require manual operation and can lead to ineffective sealing, while automatic machines are complex and costly to maintain.
Innovation Solution
A closure device featuring a T-shaped structure with angled guides and a support surface, along with a sealing mechanism, facilitates the automatic folding and sealing of major and minor flaps, allowing for efficient and reliable closure and sealing of corrugated boxes without the need for manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual hand-held devices are used for closing and sealing boxes, then operation simplicity is maintained, but sealing effectiveness deteriorates
Solution Approach 1:
The box itself serves as part of the closing mechanism. The flaps are designed to fold into each other automatically when the box is compressed during the closing process, eliminating the need for complex manual manipulation while ensuring effective sealing through the self-closing action of the flaps
2Productivity
If automatic closing machines are used, then productivity and sealing effectiveness are improved, but device complexity and maintenance cost increase
Solution Approach 1:
The closing process is segmented into distinct functional zones: the T-shaped structure provides a stable platform, guides direct flap movement, compression elements apply closing force, and sealing elements secure the flaps. This segmentation allows each component to perform its function simply and reliably without requiring complex integrated machinery
Solution Approach 2:
Guides are introduced as intermediary elements between the compression force and the flaps. These guides ensure proper flap alignment and movement direction during closing, enabling effective sealing without requiring complex positioning mechanisms or automated manipulation systems
3Reliability
If complex automated systems are implemented, then sealing reliability is improved, but ease of operation and maintenance deteriorate
Solution Approach 1:
The flaps are designed to fold into each other automatically when compression is applied, and the sealing elements engage the flaps in their natural folded position. This self-aligning mechanism ensures reliable sealing without requiring precise manual positioning or complex automated control systems
Solution Approach 2:
The closing mechanism uses simple, inexpensive components such as guides, compression pads, and sealing elements that can be easily replaced if needed. These components are designed for simplicity rather than durability, allowing quick replacement without affecting overall system reliability

AI summary
A closure device including a closure assembly for closing the flaps of a box. The closure assembly includes a T-shaped structure having a first horizontal surface upon which a box can move during a closure process and a guide positioned on each side of the T-shaped structure, each guide being angled relative to the T-shaped structure and adapted to close the major flaps of the box as the box is moved proximally across the T-shaped structure. The horizontal portion can be positioned vertically higher than a support surface to allow a portion of the box to move therebetween. The closure device can further include a minor flap closure device for closing the minor flaps of the box prior to closing the major flaps of the box. The closure device can also include a sealing device, such as a taping head, for sealing the box closed.
