Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bags with straps suffer from limitations such as fixed strap lengths, limited adjustment mechanisms, and multiple straps for different configurations, leading to discomfort and reduced functionality.
Innovation Solution
A bag design with adjustable straps that allow for releasable couplings and multiple attachment points along the strap length, enabling conversion between various carrying configurations like purses, handbags, and backpacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple straps are used for different bag configurations, then the bag can be used in multiple configurations (purse, handbag, backpack), but the weight of the bag increases and extra straps add unsightly appearance and get in the way
Solution Approach 1:
The patent applies universality by designing a single strap system that can perform multiple functions across different bag configurations. The straps are engineered to be adjustable and reconfigurable, allowing the same strap to serve as a short handle for handbag mode, a longer strap for shoulder bag mode, and an even longer configuration for backpack mode. This eliminates the need for separate straps for each configuration, reducing overall weight while maintaining versatility.
Solution Approach 2:
The patent applies dynamics by making the strap length and configuration changeable rather than fixed. The strap includes adjustment mechanisms that allow users to dynamically modify the strap length and attachment points depending on the desired bag configuration. This dynamic adjustability enables one strap to adapt to multiple uses, replacing what would traditionally require multiple fixed-length straps.
2Adaptability or versatility
If fixed strap lengths are used, then the strap structure is simple, but the bag functionality is reduced and user comfort is compromised
Solution Approach 1:
The patent applies dynamics by transforming the strap from a fixed-length component to an adjustable-length component. The strap incorporates adjustment mechanisms such as sliders, buckles, or telescopic sections that allow users to change the strap length according to different carrying needs. This dynamic capability enables the strap to adapt to various bag configurations and user preferences while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent applies segmentation by dividing the strap into multiple sections or segments that can be independently adjusted. The strap may include separate adjustable portions, attachment points at different locations, or modular components that can be configured in different ways. This segmentation allows for flexible length adjustment without requiring a completely complex redesign of the entire strap system.
3Ease of operation
If sliders are used to adjust strap length, then strap length can be modified, but the adjustment range is limited and the sliders are difficult to manipulate
Solution Approach 1:
The patent applies self-service by designing adjustment mechanisms that are easily operated by users without requiring complex tools or difficult manipulations. The adjustment system may include large-format sliders, easy-release buckles, or pull-tab mechanisms that allow users to quickly and intuitively adjust strap length with one hand. The design prioritizes user-friendly operation, making the adjustment process simple and accessible.
4Adaptability or versatility
If strap attachment points are small and fixed, then the attachment structure is simple, but the straps cannot be threaded through or rotated to adjust length
Solution Approach 1:
The patent applies universality by designing attachment points that can serve multiple functions. The attachment points are configured to accommodate various strap configurations, allowing straps to be threaded through, attached directly, or rotated into different positions. These multi-functional attachment points enable the same attachment mechanism to support handbag configuration, shoulder bag configuration, and backpack configuration, replacing what would traditionally require different attachment points for each use case.

AI summary
Exemplary embodiments include a mechanism that provides a systemized way to attach straps to bags that provides for versatility in attachment of straps for both positioning on the bag and for modifying the length of the straps. These straps may be used as both handles and shoulder straps for the bag through different attachment configurations allowing for the bag to be worn (and used) as one or more different types of bags (e.g., a purse, handbag, satchel, hobo bag, shoulder bag, crossbody bag, laptop bag, messenger bag, and/or tote bag) and a backpack.
