Rolling Toy With Helical Guide And Secondary Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling toys and game apparatuses, such as bowling, require complex and expensive equipment, making it difficult to play at home, and there is a need for a rolling toy that can be played indoors without specialized facilities.
Innovation Solution
A rolling toy design featuring a primary roller with a tubular-like member and a secondary roller, equipped with helical guiding means, allowing the toy to roll on a horizontal surface and stand up by adjusting the center of gravity through annular flanges and counterweights, enabling a new game to be played at home.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bowling is used as a rolling game, then the rolling distance and game excitement are improved, but the equipment complexity and facility requirements increase significantly
Solution Approach 1:
The toy is divided into two functional segments: a primary roller that contacts the ground for rolling motion, and a secondary roller contained within the tubular member that controls the rolling distance through its interaction with the cylindrical interior surface. This segmentation allows the toy to achieve bowling-like rolling distance without requiring complex bowling equipment.
2Adaptability or versatility
If rolling toys with motion sensors and audio-video signals are used, then the entertainment value is improved, but the device complexity increases
Solution Approach 1:
The toy generates entertainment through self-service mechanisms rather than external electronic systems. The secondary roller's automatic movement within the tubular member creates unpredictable rolling distances and patterns, providing entertainment value through mechanical self-animation without requiring motion sensors, audio signals, or video displays.
3Adaptability or versatility
If self-propelling rolling toys with obstacle detection are used, then the toy's ability to change route is improved, but the device complexity increases
Solution Approach 1:
The toy employs dynamic behavior through the secondary roller's movement within the cylindrical interior surface of the tubular member. As the primary roller moves forward, the secondary roller rolls along the cylindrical surface, causing the toy's orientation and route to change dynamically without requiring obstacle detection sensors or complex control systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The toy can roll a predetermined distance and stand up on its own, providing an amusement effect and allowing for a new game to be played on a horizontal support surface without the need for complex equipment, enhancing indoor playability.
Implementation Method 1
a helical guiding means: the tubular-like member and the secondary roller. The helical guiding means is/are configured for urging the secondary roller to move longitudinally toward the left end or the right end when the secondary roller is in the rolling motion on the substantially cylindrical interior surface
Implementation Method 2
configurations of the primary and secondary rollers and weights of the rollers are such that, as the primary roller is positioned having the longitudinal axis oriented horizontally, at least one of the following is satisfied: (a) a center of gravity of the rolling toy is located to the left of a leftmost annular flange... (c) a center of gravity of the primary roller is located to the left of a leftmost annular flange... thereby, the tilting of the primary roller may result in the standing thereof

AI summary
A rolling toy to be rolled on a horizontal support surface, for instance, on a floor, having a primary roller and a secondary roller. The primary roller having a tubular-like member extending along a longitudinal axis and at least one annular flange fixedly attached to the tubular-like member and extending outwardly therefrom. The secondary roller is adapted a for rolling motion upon an interior surface of the tubular-like member when the primary roller rotates about the longitudinal axis due to the rolling motion of the rolling toy on the horizontal support surface. At least one of the following includes a helical guiding means: (i) the tubular-like member and (ii) the secondary roller. Thereby, when the secondary roller is disposed on the interior surface of the tubular-like member and the primary roller is set in a rolling motion on the horizontal support surface in a predetermined direction, the rolling motion of the primary roller results in a tilting of the latter. The tilting of the primary roller may result in its standing vertically on the horizontal support surface.
