Frictional Clasp With Adjustable Cavity For One-Handed Bag Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bags with removable storage components often have cumbersome attachment mechanisms that require two hands to secure and remove storage compartments, making them inefficient for use.
Innovation Solution
A springless clasp with a protrusion and receiving portion that uses frictional fitting for secure association, featuring adjustable width cavities defined by arcuate recesses on arms, allowing one-handed operation and easy attachment/removal of storage components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional attachment mechanisms (zippers, spring clasps) are used to secure storage components, then the storage components can be securely attached, but the operation requires two hands and becomes cumbersome
Solution Approach 1:
The clasp mechanism is designed to automatically engage and lock when the bag pocket is attached to the main bag body. The protrusion portion on one component automatically inserts into the receiving cavity of the other component, creating a secure attachment without requiring manual manipulation of zippers or spring-loaded buttons. This self-securing mechanism enables one-handed operation while maintaining reliable attachment.
2Reliability
If conventional attachment mechanisms are used, then storage components can be secured, but the attachment and removal process becomes time-consuming
Solution Approach 1:
The clasp components are pre-configured with the protrusion and receiving cavity geometries that enable immediate engagement. The arcuate recesses are shaped to guide the protrusion into proper alignment during attachment, eliminating the need for manual alignment adjustments. This preliminary configuration of the attachment geometry allows for rapid one-handed attachment and removal operations.
3Adaptability or versatility
If removable storage components are added to bags, then unused space can be addressed, but the attachment mechanisms become cumbersome and inefficient
Solution Approach 1:
The attachment system is divided into two independent components: a protrusion portion on one component and a receiving portion with cavity on the other component. This segmentation allows each component to be independently manufactured and attached to different bag elements (main bag body or pocket). The simple geometric forms of the protrusion and cavity minimize the complexity of each component while enabling versatile attachment configurations.
Solution Approach 2:
The clasp mechanism with its protrusion and receiving cavity design can be universally applied to attach various storage components (pockets, compartments, accessories) to different parts of the bag system. The same basic clasp design works for attaching pockets to the main body, securing accessories, or connecting multiple components together, providing a universal attachment solution that reduces overall system complexity.

AI summary
A clasp including a protrusion portion with a protrusion, and a receiving portion defining a receiving cavity configured to receive the protrusion portion is described. The protrusion is securable in the cavity via frictional fitting of the protrusion into the cavity. The frictional fitting of the protrusion into the cavity creates a secure association between the receiving portion and the protrusion portion, and the receiving portion includes a first arm and a second arm extending from a receiving portion base. The first arm includes a first arcuate recess and the second arm includes a second arcuate recess opposing the first arcuate recess, and the first arcuate recess and the second arcuate recess define adjustable width of the cavity.
