Magnetic drinking cup stacking toy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking toys, particularly drinking cups, are unstable due to their lightweight nature, making it difficult for children to create stable configurations, and previous solutions like weighted cups only allowed vertical stacking, while magnetic toys have not addressed the challenge of stacking drinking cups effectively.
Innovation Solution
The use of small ball magnets embedded in the rim and bottom of lightweight plastic drinking cups allows for easy stacking in various configurations by aligning in an attraction mode, enabling cups to be connected in multiple positions and angles, even by young children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lightweight plastic drinking cups are used, then the cups are easy to handle and manipulate, but the cups are unstable and tend to fall when stacking
Solution Approach 1:
The patent introduces magnets as an intermediary force between the cups. Small ball magnets are embedded in the cup rims and larger magnets in the cup bottoms, creating magnetic attraction that acts as a mediator to hold cups together during stacking, thereby stabilizing the structure without adding significant weight.
Solution Approach 2:
The patent changes the physical parameter of the cups by embedding magnetic elements with specific magnetic field strengths. The small ball magnets (0.06-0.125 inches diameter) in the rims and larger magnets (0.25-0.5 inches diameter) in the bottoms create controlled magnetic attraction forces that enable stable stacking while maintaining light weight.
2Stability of the object's composition
If weighted cups are used to improve stability, then the cups become more stable for stacking, but the cups only allow vertical stacking and lose versatility
Solution Approach 1:
The patent segments the magnetic elements into two distinct types: small ball magnets embedded in the cup rims and larger magnets embedded in the cup bottoms. This segmentation allows for multiple interaction patterns - rim-to-rim magnetic attraction enables horizontal and angled stacking, while bottom-to-bottom attraction enables vertical stacking, providing versatility without sacrificing stability.
Solution Approach 2:
The magnetic elements serve multiple functions: they provide stable attachment during stacking, enable various stacking configurations (vertical, horizontal, angled), and work with both lightweight plastic cups and heavier materials. The same magnetic principle applies regardless of cup weight or desired configuration.
3Adaptability or versatility
If magnets are embedded in cups to enable magnetic stacking, then various stacking configurations become possible, but the manufacturing complexity increases
Solution Approach 1:
The patent uses spherical ball magnets in the cup rims instead of flat or irregularly shaped magnets. The spherical shape allows for easy embedding in the circular rim structure and provides uniform magnetic attraction from all directions, simplifying both the embedding process and the magnetic interaction during stacking.
Solution Approach 2:
The patent employs small, inexpensive ball magnets that can be easily manufactured and embedded. These simple magnetic elements are cost-effective and can be produced in large quantities, making the overall manufacturing process economically viable despite the added step of embedding magnets.

AI summary
A system with light-weight drinking cups that use small ball magnets embedded in the cup rim and in the bottom cup center. In a preferred embodiment, there can be four magnets at four locations around the rim and a magnet in the center of the bottom of the cup. This arrangement allows cups to be stacked easily even by very young children in a large variety of ways and configurations. The ball magnets align in an attraction mode. Hence, any two cups can be stuck together simply by bringing two of the magnets into proximity. The toy can yield large stacks with connections in many different configurations.
