Carrying Case Strap Positioning via Aperture Grid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handbags or carrying cases lack adjustability and personalization options, as straps often require fixed positioning and cannot be easily customized with various accessories, failing to meet individual user preferences for comfort and style.
Innovation Solution
A handbag or carrying case design featuring a body with multiple apertures on its sides and elongate straps with corresponding apertures, utilizing snap fasteners that allow for variable attachment and removal, enabling users to position straps as desired and personalize the case with decorative snap fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If straps are fixed to the body at predetermined positions, then the structural simplicity is maintained, but the adaptability for different users and customization options are limited
Solution Approach 1:
The body is divided into multiple aperture positions arranged in rows and columns, segmenting the attachment area into discrete locations. This allows straps to be attached at various positions without requiring a completely new structure, thereby increasing adaptability while maintaining relatively simple construction.
Solution Approach 2:
The apertures serve multiple functions: they enable strap attachment at different positions for adaptability, allow for customization with decorative elements, and provide a standardized interface for various strap configurations. This multi-functionality increases versatility without proportionally increasing structural complexity.
2Adaptability or versatility
If multiple apertures are added to the body for variable strap attachment, then the adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple apertures are pre-formed in the body during manufacturing at predetermined positions in rows and columns. This preliminary action allows the body to be produced with all necessary attachment points built-in, making the manufacturing process more efficient despite the increased number of features, as the apertures can be created using standardized drilling or punching operations.
3Ease of operation
If snap fasteners are made separable for removable straps, then the ease of operation for adjustment is improved, but the reliability of strap attachment may be reduced
Solution Approach 1:
The snap fastener system provides dynamic attachment, allowing straps to be easily attached and detached by engaging or disengaging the snap components. The design incorporates sufficient engagement force when attached to ensure reliability during use, while maintaining ease of release when needed for adjustment or removal.
4Adaptability or versatility
If decorative snap fasteners are allowed for personalization, then the adaptability for customization is improved, but the device complexity increases
Solution Approach 1:
The snap fastener system serves dual purposes: functional attachment of straps and decorative personalization. The same aperture and snap fastener infrastructure used for strap attachment also accommodates decorative elements, providing customization capability without requiring separate complex attachment mechanisms for decorative items.

AI summary
Handbag or carrying case includes a body defining a retaining compartment for retaining objects and having apertures on opposed sides, and elongate straps each having opposite end regions and at least two apertures, one proximate each end region. Snap fasteners attach the straps to the first and second sides via aligning pairs of apertures, i.e., one apertures on a side of the body and one aperture on the strap. The snap fasteners may be decorative snap fasteners. Use of the snap fasteners provides for variable attachment of the straps to the body and therefore enables each user of the carrying case to position the straps as they desire.
