Bag With Parallel Gripping Cavities for Comfortable Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic bags are uncomfortable to carry due to orthogonal gripping cavities, and there is a need for reusable bags that can be easily produced and integrated into existing production lines while meeting environmental regulations.
Innovation Solution
A bag design with flaps that form handles with gripping cavities parallel to the bag walls, allowing comfortable carrying and reuse, produced by sealing and die-cutting plastic or textile sheets, and integrating a simple production process that can be easily adapted to existing lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bag is made with orthogonal gripping cavities as in prior art, then the production process is simple, but the bag is uncomfortable to carry
Solution Approach 1:
The patent inverts the conventional orthogonal arrangement of gripping cavities by making them substantially parallel to each other and parallel to the lateral edges of the bag. This inversion of the standard configuration resolves the contradiction by providing comfortable carrying (improving ease of operation) while maintaining a simple production process that can be integrated into existing manufacturing lines.
2Adaptability or versatility
If the bag is designed for single use as in prior art, then the production cost is low, but the bag cannot be reused for other purposes
Solution Approach 1:
The patent applies universality by designing the bag with parallel gripping cavities that enable multiple functions: carrying purchased goods, serving as a shopping basket, and functioning as an apparel accessory when worn on the back. This multi-functional design achieves reusability for various purposes without significantly complicating the production process, as the same sealing and die-cutting operations create all the necessary features.
3Adaptability or versatility
If the gripping cavities are made parallel to the bag walls, then the bag can be worn as an apparel accessory, but the production process becomes more complex
Solution Approach 1:
The patent inverts the conventional orthogonal orientation of gripping cavities to make them parallel to the bag walls and lateral edges. This inverted configuration enables the bag to be worn as an apparel accessory by distributing weight comfortably across the shoulders. The die-cutting process, while creating a new geometry, remains integrated into existing production lines and does not require significant additional complexity.

AI summary
Bag (1) comprises: - at least a first wall (2) and at least a second wall (3) mutually joined at least a lateral edge (4) and at least a bottom edge (5) to define a containment space (6) and having respective first and second upper edges (7, 8) spaced apart from one another to define an access opening to the containment space (6); - at least a first and a second flap (9, 10) spaced apart from one another, which extend from the first wall (2) beyond the first upper edge (7); - at least a third and a fourth flap (11, 12) spaced apart from one another, which extend from the second wall (3) beyond the second upper edge (8); wherein the first flap (9) is associated with the second flap (10) to form a first gripping handle (13) and that the third flap (11) is associated with the fourth flap (12) to form a second gripping handle (14), the first gripping handle (13) and the second gripping handle (14) enclosing respective gripping cavities (15) having the lying planes substantially parallel to said first lateral wall (2) and second lateral wall (3).
