Enclosing Cup with Internal Handle for Multi-Point Hand Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drinkware designs present a single liquid surface in contact with the air, regardless of the liquid's volume, which does not provide adequate hand encirclement or multiple contact points for the handle, limiting user interaction and comfort.
Innovation Solution
A drinkware design featuring a base, an enclosing container with an internal cavity, a mouth, and a handle that is either integrally formed or attached via screws or a threaded mechanism, where the handle is concentric with the container and can be attached at multiple points, allowing the container to enclose the user's hand and provide multiple liquid surfaces in contact with the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional drinkware container is designed with a single opening, then the structure is simple, but the user's hand cannot be enclosed and only one liquid surface contacts the air
Solution Approach 1:
The handle is nested within the container body, with the container wall enclosing the handle structure. This allows the user's hand to be surrounded by the container when gripping the handle, creating multiple contact points between the hand and container surface while maintaining a unified overall structure.
Solution Approach 2:
The design transitions from a conventional single-opening container to a three-dimensional enclosing structure where the container wall wraps around the handle in multiple directions, creating an enclosing cavity that surrounds the user's hand from multiple angles rather than providing access from a single direction.
2Ease of operation
If the handle is attached at a single point, then the attachment is simple, but the user interaction and comfort are limited
Solution Approach 1:
The handle attachment structure is divided into multiple attachment points distributed along the container wall. Instead of a single attachment point, the handle connects to the container at several locations, providing enhanced stability and multiple contact points for user interaction while distributing structural loads.
Solution Approach 2:
The handle structure serves multiple functions: it provides gripping capability, structural support, and creates additional contact points with the container wall that enhance user comfort and control. The multi-point attachment system simultaneously achieves structural integrity and improved ergonomics.
3Ease of operation
If the container encloses the handle, then multiple contact points are provided, but the manufacturing complexity increases
Solution Approach 1:
The handle and container are designed as integrated components where the handle structure is incorporated into the container body during manufacturing. The attachment points are formed as part of the molding or fabrication process rather than requiring separate assembly steps, reducing manufacturing complexity despite the enclosing geometry.
Solution Approach 2:
The handle attachment features and container wall structures are prepared in advance during the container fabrication process. Attachment points, recesses, and structural features are pre-formed in the container body before final handle installation, simplifying the assembly process and reducing the complexity of the enclosing structure.

AI summary
An enclosing cup includes a base, an enclosing container for holding liquid, a handle and a mouth. The enclosing container is supported by the base. The mouth is supported by the enclosing container. The enclosing container incorporates a cavity for containing liquid, and an aperture. The mouth communicates with the cavity via the aperture. Liquid flows into and out of the cavity via the aperture and the mouth. The handle is disposed within the enclosing container. The liquid is disposed around the handle and a user's hand that holds the handle. The handle makes contact with the inner side of the enclosing container at one or more points. The handle allows a user to hold and operate the enclosing cup, while the mouth of the enclosing cup allows the user to drink the liquid out of the enclosing cup.
