Mobile Playing Card Cart with Freewheeling Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Players in card games face difficulty accessing a central draw and discard deck when seated at rectangular or circular tables, especially when the deck is out of reach due to its static location, particularly affecting those with limited mobility.
Innovation Solution
A mobile playing card cart with a freewheeling base and tray compartments that can be rolled across the table, equipped with wheels and handles, optionally motorized for easy movement, allowing cards to be placed proximate to players, accommodating various table shapes and player positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the draw deck and discard deck are positioned at a static location in the center of the table, then the deck location is stable and easy to manage, but players seated at rectangular or circular tables cannot reach the deck when spaced far apart
Solution Approach 1:
The patent applies the dynamics principle by transforming the static deck position into a mobile one. The cart with wheels allows the draw deck and discard deck to be dynamically repositioned across the table surface, enabling players at various distances and positions to access the cards without straining. The base includes a tray with compartments that can be rolled to different locations.
Solution Approach 2:
The patent segments the card playing system by separating the decks from the table surface and placing them in a movable cart. The tray is divided into multiple compartments (first compartment for draw deck, second compartment for discard deck), allowing independent organization and movement of different card stacks.
2Adaptability or versatility
If a radial arm with a compartment tray is used to allow rotation around the table center, then players at round tables can access materials, but this system does not work for square or rectangular tables where users sit at varied distances from the center
Solution Approach 1:
The patent applies universality by designing a mobile cart that can serve multiple table configurations (round, square, rectangular). Unlike the radial arm system that is specific to round tables, this cart can be rolled to any position on any table shape, making it universally applicable to different game settings and player arrangements.
Solution Approach 2:
The mobile cart provides dynamic positioning capability that adapts to different table geometries. The wheels enable the cart to reach players regardless of whether they are seated at varied distances from the center or positioned along the edges of rectangular tables, overcoming the limitations of fixed radial arm systems.
3Ease of operation
If the cart is made freewheeling and not attached to the table, then the cart can be easily rolled to players with limited mobility, but the cart requires stabilization to prevent falling over
Solution Approach 1:
The patent implements a freewheeling cart design that is not permanently attached to the table, allowing easy rolling to players with limited mobility. The cart can be propelled and directed in any direction across the table surface, providing dynamic access to cards for players who cannot reach a fixed position.
Solution Approach 2:
The cart is equipped with handles that extend upward from the base, allowing players or assistants to grasp and propel the cart before movement is needed. This preliminary preparation of the propulsion mechanism enables easy initiation of movement to reach players with limited mobility.

AI summary
What is disclosed is a mobile freewheeling playing card cart. The cart has a tray positioned upon a rolling base that is capable of holding two or more stacks of playing cards. The tray features barriers and depressions around the card stacks that make the cards more easily accessible. The cart includes one or more handles used to maneuver the cart. The cart may be motorized through the use of an integrated battery and remote control.
