Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Athletic attire and equipment often lack portability and compactness, requiring multiple items that increase weight and bulk, and existing solutions do not efficiently provide multiple features in a single piece of equipment.
Innovation Solution
A compressible backpack design featuring a central body with moveable portions, channels with apertures, and tethers anchored by control mechanisms that allow for expansion and compression, maintaining structural integrity while minimizing surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If athletic equipment is designed to provide multiple features, then versatility is improved, but device complexity increases
Solution Approach 1:
The bag integrates multiple functions including compression, expansion, storage, and wearability into a single device. The compressible segments with flanges and cavities allow the bag to serve both as a compression device and a storage container, eliminating the need for separate equipment while maintaining versatility
Solution Approach 2:
The bag is divided into multiple compressible segments with flanges and cavities that can independently compress and expand. This segmentation allows the bag to maintain structural integrity during compression while enabling versatile functionality through the coordinated movement of segments
2Volume of moving object
If the bag is designed to be compressible, then volume is reduced, but structural integrity may be compromised
Solution Approach 1:
The bag is divided into multiple compressible segments with flanges and cavities that can independently compress and expand. This segmentation allows the bag to maintain structural integrity during compression while enabling versatile functionality through the coordinated movement of segments
Solution Approach 2:
The bag utilizes flexible flanges and cavities that can deform during compression while maintaining structural integrity. The flanges act as flexible structural elements that preserve the bag's strength even when compressed to reduced volume
3Ease of operation
If the bag allows moveable portions, then portability is improved, but device complexity increases
Solution Approach 1:
The bag incorporates moveable portions including compressible segments, flanges, and cavities that can dynamically adjust their position and volume. This dynamic design improves portability by allowing the bag to be compressed and expanded easily while the interconnected nature of the segments keeps the overall device relatively simple

AI summary
Present aspects hereof are directed to a compressible backpack having a plurality of compressible flanges that shift along a vertical axis of the compressible bag upon tensioning of at least one bag tether. In some aspects, a locking mechanism restricts travel of the bag tethers in a first direction, while permitting travel in a second direction upon triggering a locking release.
