Solution Overview
Problem
Conventional cartons lack a robust and comfortable handle mechanism for securely grasping and carrying multiple beverage containers or articles, leading to potential handle failure and discomfort during use.
Innovation Solution
A carton design featuring a reinforced handle formed by multiple layers of material, with foldable handle panels that extend upwardly and are spaced apart, providing a sturdy and comfortable grip, and incorporating locking features and glue openings for secure assembly without the need for additional fastening materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional cartons use simple handle structures, then the device complexity is low, but the handle strength and reliability are insufficient for securely carrying multiple articles
Solution Approach 1:
The handle is divided into multiple separate panels (first handle panel, second handle panel, third handle panel) that are foldably connected to different carton panels. This segmentation allows each panel to contribute to the overall handle strength while maintaining a relatively simple individual structure for each component.
Solution Approach 2:
The handle panels are nested within the carton structure itself, with the handle panels being foldably connected to the carton's top panel, first side panel, and second side panel. This nesting integrates the handle into the existing carton geometry, providing strength without adding significant external complexity.
2Reliability
If the handle is made thicker or with more material layers, then the handle strength increases, but the manufacturing complexity and material usage increase
Solution Approach 1:
The handle structure merges multiple carton panels (top panel, first side panel, second side panel) into a unified handle assembly. By combining these existing structural elements, the patent achieves high reliability without requiring additional thick materials or complex manufacturing processes.
Solution Approach 2:
The handle gains strength through three-dimensional spatial arrangement rather than increased material thickness. The handle panels extend upwardly and are spaced apart to form a rigid triangular configuration, providing structural reliability through geometric dimensioning rather than material bulk.
3Ease of operation
If the handle panels extend upwardly and are spaced apart, then the comfort of grasping improves, but the structural complexity of the handle increases
Solution Approach 1:
The handle panels are positioned to create a localized grasping zone with optimal dimensions for human hand comfort. The first and second handle panels extend upwardly and are spaced apart by a distance suitable for finger placement, providing ergonomic quality at the specific interaction point without complicating the overall carton structure.
Solution Approach 2:
The handle panels are designed to be foldable rather than fixed, allowing the handle structure to dynamically adjust during grasping. The foldable connections enable the handle to conform to user hand positioning while maintaining structural integrity, improving comfort without requiring complex adjustable mechanisms.
4Stability of the object's composition
If locking features and glue openings are incorporated into the handle, then the assembly security improves, but the manufacturing precision requirements increase
Solution Approach 1:
The locking features and glue openings are pre-formed as integral parts of the handle panels during the carton manufacturing process. This preliminary action ensures proper alignment and positioning before final assembly, achieving stable connections without requiring high-precision field adjustments during carton erection.
Solution Approach 2:
The handle structure incorporates self-aligning locking features that automatically position themselves during assembly. The geometric configuration of the locking features and glue openings allows the handle panels to self-align with the carton panels, reducing the need for high-precision manual positioning while ensuring assembly stability.

AI summary
A carton for holding a plurality of articles. The carton comprises a plurality of panels that extends at least partially around an interior of the carton and comprises at least a top panel. A handle is positionable between a first position and a second position. The handle comprises at least a first handle panel and a second handle panel, and at least one of the first handle panel and the second handle panel is foldably connected to the top panel. At least one of the first handle panel and the second handle panel is generally coplanar with at least a portion of the top panel in the first position of the handle. Each of the first handle panel and the second handle panel extends upwardly relative to the top panel and the first handle panel is spaced apart from the second handle panel in the second position of the handle.
