Convertible Container with Base Connecting Cap for Cup Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers convertible between a bottle and a cup lack reusability and stability, with the base serving as a cover reducing aesthetic appeal and stability when converted into a cup.
Innovation Solution
A container design that includes a base connecting cap and a base member, allowing 180° rotation to convert into a cup, with the base connecting cap enhancing stability and visibility, resembling a wine glass shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base of the cup is used as a cover, then the container can be converted into a cup, but the aesthetic feature is reduced when converted into the cup
Solution Approach 1:
The container is divided into separate functional components: the base connecting cap that attaches to the bottle knob, the cover that seals the opening, and the base member that forms the cup base. This segmentation allows each component to serve its specific function without compromising aesthetics - the base connecting cap resembles a wine glass base when attached, and the cover maintains a clean appearance when sealed.
Solution Approach 2:
The base member is extracted as a separate component that can be attached or removed independently. When the container is in bottle form, the base member is taken out and stored separately, allowing the bottle to maintain its original aesthetic appearance. When converted to cup form, the base member is attached to create the cup base, solving the aesthetic compromise issue.
2Adaptability or versatility
If the base of the cup is used as a cover, then the container can be converted into a cup, but the stability is reduced due to center of gravity limitations
Solution Approach 1:
By separating the base function into an independent base member that attaches to the base connecting cap, the design allows for optimized weight distribution. The base member can be designed with appropriate mass and geometry to lower the center of gravity when in cup configuration, improving standing stability without affecting the bottle form.
3Adaptability or versatility
If the container is converted into a cup by 180° rotation, then the container can be reused, but the manufacturing complexity increases
Solution Approach 1:
The base connecting cap serves multiple functions: it attaches to the bottle knob during bottle configuration, connects the base member during cup configuration, and maintains the structural integrity in both forms. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in manufacturing complexity despite the added convertibility feature.
4Stability of the object's composition
If a base connecting cap is added to enhance stability and aesthetics, then the cup conversion is improved, but the device complexity increases
Solution Approach 1:
The base connecting cap merges multiple functions into a single component: it serves as the attachment point for the bottle knob, the connection interface for the base member, and the structural element that maintains stability in both bottle and cup configurations. This merging approach improves stability and aesthetics while minimizing the increase in device complexity by consolidating functions rather than adding separate components.

AI summary
The present disclosure relates to a container, and more particularly, to a container convertible between a cup and a bottle. A container convertible into a cup according to the present disclosure includes: a main body having a bottle shape and including a closed knob and an opened opposite portion; a base connecting cap inserted and coupled to the knob; a cover coupled to the opposite portion of the main body; and a base member disposed below the cover and wrapped together with the cover by a film. Here, the container is converted into the cup by fastening the base connecting cap to the base member in a state in which the main body is rotated by 180° and the base member is taken out.
