Carton With Integral Hinged Handle Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carton packaging solutions fail to provide a strong and comfortable carrying handle that efficiently utilizes minimal material, while also ensuring effective load-bearing capacity and ergonomic comfort for users.
Innovation Solution
A carton design featuring a hinged carrying handle structure formed from panels, with tabs and web panels that fold around articles to create handle openings, allowing users to grasp the carton comfortably and securely, even when handling heavy loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carrying handle is added to the carton, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The handle is divided into multiple segments including a handle body, a first tab, and a second tab that can independently fold and position. This segmentation allows the handle to be formed from multiple panels of the carton, distributing the structural complexity across separate components while maintaining ease of carrying functionality.
Solution Approach 2:
The handle structure is nested within the carton itself, with tabs and panels forming the handle using the carton's own material. The handle is not a separate attached component but is integrated into the carton structure, reducing overall device complexity while providing carrying functionality.
2Strength
If the handle structure uses more panels and folding components, then the strength and load-bearing capacity are improved, but the material usage increases
Solution Approach 1:
The carton panels serve multiple functions: they form the container structure and simultaneously provide the handle components. The same material used for the carton body is used for the handle, eliminating the need for separate handle material and reducing overall material usage while maintaining strength through the multi-functional design.
Solution Approach 2:
The handle uses dynamic folding mechanisms where tabs can be folded into different positions to create the handle shape. This dynamic formation allows the handle to be created from existing carton panels without adding material, as the panels are simply repositioned through folding rather than being added as separate rigid components.
3Adaptability or versatility
If the handle is designed to fold around articles, then the adaptability to various article sizes is improved, but the ease of manufacture decreases
Solution Approach 1:
The handle is segmented into multiple tabs and panels that can independently fold and adjust. This segmentation provides adaptability to different article sizes and shapes, as each segment can be folded into the optimal position to accommodate the specific article configuration while maintaining the handle's structural integrity.
Solution Approach 2:
The handle employs dynamic folding lines and flexible panels that can be manipulated during assembly to accommodate various article configurations. This dynamic design allows the same handle structure to adapt to different article sizes and shapes, with the folding mechanisms enabling the handle to conform to the specific packaging requirements.

AI summary
A package includes a carton (10) and a plurality of articles (B). The carton includes carton walls (14, 16, 26b/30b) and at least one handle structure (HA2) formed from at least one (26b/30b) of the carton walls. The at least one handle structure includes a tab (44b) formed from the at least one of the carton walls. The tab is hingedly connected, by a hinged connection (42b), to the at least one of the carton walls and arranged to fold at least in part about an article disposed within the carton to form at least a portion of a handle opening (40b) so as to allow a user (U) to grasp a portion of the article and the carton disposed adjacent to the article.
