Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machine systems require multiple machines and significant manual labor for creating custom-sized boxes, as they focus primarily on box creation and sealing, without efficient mechanisms for infeed, separation, and creasing of sheet material.
Innovation Solution
The development of a packaging machine with an infeed mechanism that feeds sheet material without creating folds or creases, a separation system using angled knives for efficient cutting, and a creasing system with rotating rollers to form transverse creases, all aimed at automating the process of creating custom-sized packaging templates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional packaging machine systems are used, then box creation and sealing functions are provided, but multiple machines and significant manual labor are required for infeed, separation, and creasing operations
Solution Approach 1:
The patent combines multiple previously separate functions (infeed mechanism, separation system with knives, and creasing system with rollers) into a single integrated packaging machine. This merging eliminates the need for multiple separate machines while maintaining full automation capabilities for feeding sheet material, separating it into individual sheets, and creating necessary creases.
Solution Approach 2:
The packaging machine is designed as a multi-functional device that performs infeed, separation, and creasing operations within a single machine platform. The machine can handle various sheet materials and perform multiple operations sequentially, making it a universal solution that replaces several specialized machines.
2Productivity
If sheet material is fed through traditional infeed mechanisms, then material is advanced into the machine, but folds and creases are created in the sheet material
Solution Approach 1:
The infeed mechanism uses a low friction surface specifically at the contact point with the sheet material to prevent folding and creasing. This localized modification of surface properties allows the material to advance smoothly without damage while maintaining high productivity.
Solution Approach 2:
The low friction surface creates a uniform, low-resistance path for sheet material advancement, eliminating variations in friction that could cause folding or creasing. This equipotential approach ensures consistent, smooth material flow through the infeed mechanism.
3Ease of manufacture
If multiple separate machines are used for packaging operations, then specialized functions are provided, but manual labor and machine complexity increase
Solution Approach 1:
By merging infeed, separation, and creasing functions into one machine, the patent simplifies the overall packaging process and eliminates the need for manual transfer between multiple machines, thereby reducing manual labor while maintaining ease of manufacture.
4Manufacturing precision
If conventional cutting methods are used, then sheet material is separated, but cutting precision and efficiency are insufficient for custom-sized boxes
Solution Approach 1:
The separation system uses movable knives that can be dynamically positioned and adjusted to achieve precise cuts for custom-sized boxes. The knives move through the sheet material in a controlled manner, combining precision with efficient separation speed.

Function Achieved in This Case
This integrated system enables efficient automation of packaging template creation, reducing manual labor and machine complexity, while ensuring accurate and efficient formation of custom-sized boxes without the need for multiple machines.
Implementation Method 1
The first low friction surface and the second low friction surface form an acute angle that is configured to enable the sheet material to be advanced into the packaging machine without creating any folds or creases in the sheet material
Implementation Method 2
a first knife with a mounted end, a free end, and a first knife edge extending at least partially therebetween, the first knife edge being angled relative to a cutting edge of the cutting table to create a contact point between the first knife edge and the cutting edge of the cutting table
Implementation Method 3
a first creasing roller that is oriented across the sheet material and transverse to the length of the sheet material, the first creasing roller having a first creasing ridge extending radially therefrom, the first creasing roller being configured to rotate to engage the first creasing ridge with the sheet material to form a crease in the sheet material
