Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelf-ready packaging cartons face inefficiencies such as wasted space, difficulty in viewing products, incorrect opening, and inability to handle irregularly shaped items, leading to increased costs and packaging waste.
Innovation Solution
A carton blank designed with tear features and cutouts that allow easy viewing and intuitive opening, enabling transformation into two display sections for efficient storage and display, accommodating multiple products with varying shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If products are packaged in traditional single-row cartons, then product protection is ensured, but space utilization is wasted and transportation costs increase
Solution Approach 1:
The patent implements a nested dual-carton structure where a second carton is placed inside the first carton. This nesting arrangement allows two separate product displays to be transported together in a single outer carton, maximizing space utilization and reducing the number of outer cartons needed for transportation, thereby decreasing packaging waste.
Solution Approach 2:
The patent combines two individual carton structures into a single integrated packaging unit. By merging the first and second cartons with shared walls and integrated base structures, the design achieves efficient space utilization while maintaining the functionality of separate product displays.
2Ease of operation
If cartons use perforated tear portions for opening, then opening is assisted, but users may mistakenly tear in the wrong direction causing products to fall out
Solution Approach 1:
The patent employs asymmetric tear portion designs where the tear lines are positioned and oriented differently in the first carton versus the second carton. The first tear portion extends from the front wall while the second tear portion extends from the rear wall, creating an asymmetric configuration that provides visual and structural cues to guide users in the correct opening direction, preventing mistaken tearing.
Solution Approach 2:
The patent introduces directional indicators and structural guides as intermediaries between the user and the tearing action. These elements mediate the opening process by providing visual cues and physical guidance that steer the user's hand toward the correct tear line, ensuring reliable opening without confusion.
3Ease of manufacture
If cartons are designed for shelf-ready display, then displayability is enhanced, but the structure becomes complex and harder to manufacture
Solution Approach 1:
The patent designs the cartons with multi-functional elements that serve multiple purposes. The flaps serve both as structural components for carton assembly and as display surfaces for product information. The base structures provide both support functions and nesting interfaces. This universality reduces the need for additional specialized components, simplifying manufacturing while achieving shelf-ready display capabilities.

AI summary
A carton blank (100) includes a first main panel (102), a second main panel (104), a third main panel (106), and a fourth main panel (108). The blank further includes a pair of parallel lines (154, 156) of separation that extend through the first main panel, the second main panel, and the fourth main panel. The pair of parallel lines of separation are equidistant from one another throughout the first main panel, the second main panel, and the fourth main panel. Further, the pair of parallel lines of separation define a first tear feature that extends through the first main panel and the second main panel, and a second tear feature that extends through the fourth main panel. The blank also includes a single line (166) of separation that extends through the third main panel, connecting the first and second tear features.
