Adjustable Bag Panels for Custom Compartments Without Zippers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bags lack customizable inner compartments without the drawbacks of zippers or hook-and-loop materials, which add cost, weight, or interfere with contents.
Innovation Solution
A bag system with adjustable panels and straps that allow for customizable subdivision of the inner compartment using snap fasteners to secure interchangeable panels, minimizing interference with contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If zippers are used to enable modification of inner dimensions, then adaptability is improved, but weight and cost increase
Solution Approach 1:
The inner compartment is segmented into multiple adjustable panels that can be independently positioned and secured. These panels divide the compartment into customizable sections, allowing adaptability without requiring heavy zipper mechanisms throughout the entire bag structure.
Solution Approach 2:
Snap fasteners serve as intermediary elements that connect the adjustable panels to the bag structure and to each other. These lightweight snap fasteners enable panel attachment and detachment without the weight and complexity of zippers, while still providing secure connection.
2Adaptability or versatility
If hook-and-loop materials are used for panel attachment, then adaptability is improved, but interference with contents occurs
Solution Approach 1:
The hook-and-loop materials are extracted from the interior surfaces where they would interfere with contents and relocated to the exterior surfaces of the adjustable panels. This allows the panels to be attached to the bag structure without the rough textures being exposed to items placed inside the bag.
Solution Approach 2:
Snap fasteners are introduced as intermediary connection elements that attach the panels to the bag structure from the exterior. This eliminates the need for hook-and-loop materials on interior surfaces, preventing interference with contents while maintaining panel adjustability.
3Adaptability or versatility
If zippers are used for panel attachment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The bag structure is segmented into modular components (adjustable panels, straps, snap fasteners) that can be independently assembled and configured. This modular approach simplifies the overall structure compared to integrated zipper systems, while maintaining high adaptability for compartment customization.
Solution Approach 2:
Snap fasteners serve as simple intermediary connection elements that replace complex zipper mechanisms. These fasteners provide secure attachment with minimal structural complexity, allowing panels to be easily attached and detached without complex interlocking parts.

AI summary
A bag system including a bag, a first set of straps secured to a first interior surface of the bag, a second set of straps secured to a second interior surface of the bag, and a panel received within the bag. The first panel has first fold line proximate a first end to define a first fold portion and a second fold line proximate a second end to define a second fold portion, and a panel portion defined therebetween. The first fold portion passes between the first interior surface and a strap of the first set of straps with the first end of the panel being releasably secured to the panel portion. The second fold portion passes between the second interior surface and a strap of the second set of straps with the second end of the panel being releasably secured to the panel portion to subdivide the bag interior.
