Package Box Height Adjustment Device with Cutting Work Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for adjusting the height of prefabricated package boxes based on filling volume face issues with flaps returning to their original position, leading to difficulties in mounting covers and potential breakage of fold lines in corrugated cardboard boxes, especially when the folding lines are not accurately positioned on the inner or outer surface.
Innovation Solution
A device featuring a cutting work tool that creates continuous cutting lines on the outer surface of the box, using the inner surface film as a hinge for flaps, eliminating the need for binding and ensuring accurate folding without damaging the inner surface, and incorporating a measuring device to detect filling height for precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If flaps are folded and glued together to keep them folded, then the flaps can be secured in position, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The invention extracts the harmful element (glue/binding) from the system by using cutting lines that eliminate the need for binding. The cutting lines create a structure where flaps remain folded without requiring additional binding materials or complex gluing processes, thus simplifying the overall closing operation while maintaining flap position stability.
Solution Approach 2:
The cutting lines are created in advance during the box manufacturing process, before the closing operation. This preliminary action of cutting creates the necessary structural conditions for flaps to fold and remain in position without requiring subsequent binding operations, thereby simplifying the closing process.
2Ease of operation
If folding lines are made on corrugated cardboard boxes, then flaps can be folded to close the box, but the fold lines may break uncontrolled and the inner surface may be damaged
Solution Approach 1:
The invention applies different treatments to different parts of the box wall. The cutting lines are made only on the outer surface of the box, leaving the inner surface and the core corrugated structure intact. This local differentiation allows flaps to fold smoothly on the outer surface without compromising the structural integrity and reliability of the inner surface and folding lines.
3Volume of stationary object
If box height is adjusted to match filling volume, then space is saved in transportation, but the box closing becomes more difficult when flaps return to original position
Solution Approach 1:
The invention converts the potential harm of flaps returning to their original position into a benefit by using cutting lines that create a self-locking folding structure. The cutting lines ensure that when flaps are folded to close the box, they remain in the folded position without returning, thereby facilitating easy cover mounting while maintaining optimized box height.
4Stability of the object's composition
If flaps are kept folded until cover is mounted, then proper closing is achieved, but additional binding operations are required which increase production time
Solution Approach 1:
The invention removes the binding operation from the box closing process by using cutting lines that create a structure where flaps naturally remain folded without requiring additional binding materials or operations. This extraction of the binding step directly increases productivity by simplifying and accelerating the box closing operation.
