Variable-Length Pressing Device for Corrugated Packaging Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual packaging devices for small, individual products in corrugated cardboard are inefficient due to varying product sizes, structural complexity, and the need for high-quality infrastructure, with issues in generating sufficient contact pressure for sealing and accommodating different material thicknesses.
Innovation Solution
A device with a driven pressing mechanism using pivotable press beams and adjustable distance between pressing members, which can exert mechanical pressure on corrugated cardboard packages, allowing for simultaneous pressing of two opposite sides and incorporating a cutting blade for perforation and marking, enabling easy opening and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex device with individually driven pressing members is used to close shipping packages, then the closure quality improves, but the device complexity increases
Solution Approach 1:
The pressing device is divided into two independent pressing members that can be adjusted separately, allowing each to be optimized for its specific function while maintaining overall system simplicity
Solution Approach 2:
The pressing device is designed to handle multiple package sizes and types using the same basic mechanism, with adjustment capabilities that allow one device to perform multiple closing functions
2Ease of manufacture
If rollers are used to generate contact pressure for sealing, then the sealing process simplifies, but sufficient contact pressure cannot be generated for increased packaging thickness
Solution Approach 1:
The pressing members are designed to be adjustable in position and pressure application, allowing the system to adapt to different packaging thicknesses and generate sufficient contact pressure dynamically rather than relying on fixed roller pressure
Solution Approach 2:
The device allows adjustment of pressing force and position parameters to accommodate varying packaging thicknesses, enabling sufficient contact pressure to be generated for different material thicknesses using the same basic mechanism
3Device complexity
If fixed pressing members are used in the pressing device, then the device structure simplifies, but the device cannot accommodate different material thicknesses and package sizes
Solution Approach 1:
The pressing members are made adjustable rather than fixed, allowing them to be repositioned to accommodate different package sizes and material thicknesses while maintaining a relatively simple overall device structure
Solution Approach 2:
The device is configured to allow preliminary adjustment of pressing member positions before the actual pressing operation, enabling the system to adapt to different packaging requirements in advance
4Device complexity
If manual wrapping and folding is done without assistance, then the device infrastructure requirements reduce, but the time required and user effort increase
Solution Approach 1:
The device is designed to assist users with minimal infrastructure requirements by providing self-contained pressing and closing functions that reduce manual effort and time without requiring complex external systems

Function Achieved in This Case
The device simplifies the packaging process by allowing for efficient closure of packages of varying sizes with reduced user effort, providing a secure and easy-to-open design, and reducing the need for multiple box sizes, thus optimizing operational costs and packaging efficiency.
Implementation Method 1
a counter-element (22) being provided for each movable pressing member (4, 4') in such a way that the movable pressing member (4, 4') and counter-element (22) are designed to exert a mechanical pressure on a shipping package (26) arranged between them when in use
Implementation Method 2
a toothing (25) being provided, arranged on at least one pivotable press beam (21), which produces a perforation in the shipping packaging (26) during the pressing or also closing movement
