Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carton packaging systems face challenges in automating the formation process due to design limitations, which affect material efficiency, waste reduction, and the secure holding and transportation of articles.
Innovation Solution
A packaging system and method that utilizes a conveyor and folding machine to sequentially fold a blank around articles, incorporating alignment mechanisms to position panels at predetermined angles, forming a carton with secure closure structures and retention features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a blank is designed to be automatically formed around articles using a machine, then productivity and automation are improved, but the device complexity and difficulty of automation increase due to design limitations
Solution Approach 1:
The folding machine is divided into multiple independent folding units (first folding unit, second folding unit, third folding unit, fourth folding unit), each responsible for folding specific panels (end panels, side panels, cover panels) of the blank. This segmentation allows each unit to perform a simple, dedicated function, reducing the complexity of individual components while achieving complex overall automation.
Solution Approach 2:
The blank is pre-configured with predetermined fold lines and panel configurations before entering the folding machine. The articles are also pre-positioned on the conveyor in the correct arrangement. This preliminary preparation enables the automated folding process to proceed smoothly without requiring complex real-time decision-making or adjustment mechanisms.
2Loss of substance
If material usage is reduced for cost and environmental considerations, then loss of substance is improved, but the strength and reliability of the carton may worsen
Solution Approach 1:
The carton is formed from a blank divided into multiple functional panels (end panels, side panels, cover panels, flaps) that work together to provide strength. Each panel is optimized for its specific function, allowing material to be distributed efficiently where needed rather than uniformly throughout, reducing overall material usage while maintaining structural integrity.
Solution Approach 2:
The folding process creates three-dimensional curved and angled structures from the flat blank, forming rigid geometric shapes (boxes, corners, edges) that provide structural strength. These folded configurations distribute mechanical loads effectively, allowing the carton to maintain strength with minimal material.
3Reliability
If the carton is designed to securely hold and transport articles, then reliability is improved, but the device complexity and automation difficulty increase
Solution Approach 1:
The blank includes multiple panels (end panels, side panels, cover panels) and flaps that can be independently folded and positioned to create secure closure structures. This segmentation allows each panel to contribute specifically to article retention, with flaps providing closure and panels providing structural containment, achieving reliable article security through simple, modular folding actions.

AI summary
A packaging system includes a conveyor configured to convey a group of articles and a blank along a packaging path. The packaging system includes a folding machine configured to fold a first end panel of the blank relative to a main panel of the blank and to fold a second end panel of the blank relative to the main panel, after the first end panel is folded, as the group of articles and the blank travel along the packaging path. The packaging system includes an alignment machine configured to position a first side panel and a second side panel of the blank at a predetermined angle relative to the main panel as the group of articles and the blank travel along the packaging path.
