Packaging Box with Integrated Reel and Cutting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum packaging systems face issues such as contamination of vacuum bag rolls during initial use, difficulty in cutting vacuum bags to the correct length, and reduced operational convenience due to the need for external cutters and separate storage solutions.
Innovation Solution
A packaging box with a rotatable reel and integrated cutting device, featuring a guide rail and protective cover, which allows for convenient storage, transportation, and precise cutting of vacuum bag rolls without exposing them to contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vacuum bag roll is stored in a shrinkable film or packaging box, then the vacuum bag roll is protected during transportation, but the user needs to remove the packaging to access the vacuum bag roll, leaving it exposed and susceptible to bacterial contamination
Solution Approach 1:
The patent combines the protective packaging function and the cutting function into a single integrated packaging box. The cutting device is built into the box, allowing users to cut vacuum bags directly within the protected environment, eliminating the need to remove the vacuum bag roll from its protective housing.
Solution Approach 2:
The packaging box serves as an intermediary structure that provides both protection and functionality. Instead of simply storing the vacuum bag roll, the box actively facilitates the cutting operation while maintaining the protective environment, mediating between the need for sanitation and ease of operation.
2Manufacturing precision
If the user uses external cutters like scissors or fruit knives to cut vacuum bags, then cutting can be performed, but it is difficult to guarantee flush end faces, leading to waste and aesthetic issues
Solution Approach 1:
The packaging box provides self-service cutting functionality with a built-in cutting device that automatically ensures flush cuts. The design includes a cutting blade that moves along a guide rail, allowing users to achieve precise cuts without needing external cutting tools or skills.
Solution Approach 2:
The patent replaces the manual cutting mechanism (scissors or fruit knives requiring user skill) with a guided mechanical cutting system. The cutting blade moves along a predetermined path on a guide rail, substituting user skill with a mechanical guidance system to ensure consistent flush cuts.
3Ease of operation
If the user stores the vacuum bag roll with the original packaging box or another packaging box after cutting, then storage is possible, but this greatly reduces the operational convenience of the user
Solution Approach 1:
The packaging box is designed to be multi-functional: it serves as protective packaging during transportation, provides a built-in cutting device for precise cutting, and continues to serve as the storage container after cutting. This eliminates the need for separate storage solutions and maintains operational convenience throughout the entire usage cycle.
4Adaptability or versatility
If a rolling bag bin is added to the vacuum packaging machine to contain the vacuum bag roll, then storage and cutting functions are integrated, but the size and cost of the machine increase, limiting widespread adoption
Solution Approach 1:
The patent merges the storage function and cutting function into a single compact packaging box that can be independently used. This eliminates the need to integrate these functions into the vacuum packaging machine itself, keeping the machine size and cost down while still providing integrated storage and cutting capabilities through the separate box unit.
