Solution Overview

Problem

Existing top toys experience a decrease in speed after initial release and lack dynamic movement variation when interacting with battlefield walls, resulting in predictable and unexciting gameplay.

Innovation Solution

The top toy set incorporates gears or rollers with engaging teeth that interact with guide members, utilizing resistance mechanisms like springs or clutches to transmit rotational energy, enhancing speed and movement dynamics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the top toy moves along the protruding wall by sliding, then the top toy can change direction and expand the battle, but the speed decreases and the movement becomes predictable

Engineering Contradiction:
Improvemovement variationVSAvoidspeed
Core Design Contradiction:
Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent replaces the sliding mechanical interaction with a rolling interaction. The top toy is equipped with wheels that engage with the protruding wall, allowing the toy to roll along the wall rather than slide. This substitution of mechanical interaction mode enables the top toy to maintain speed while achieving directional changes and movement variation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces dynamic elements including springs and movable components that allow the top toy to adapt its movement characteristics in real-time. The spring mechanisms enable the top toy to accelerate and decelerate dynamically, and the movable parts allow adjustment of movement patterns, transforming the predictable motion into dynamic and varied movement.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the top toy rotates and attenuates rotational energy, then the top toy can maintain stability, but the speed and movement excitement decrease

Engineering Contradiction:
ImprovestabilityVSAvoidspeed
Core Design Contradiction:
Stability of the object's compositionVSSpeed

Solution Approach 1:

The patent employs dynamic spring mechanisms and movable components that allow the top toy to adjust its rotational energy and movement characteristics in real-time. These dynamic elements enable the top toy to maintain stability when needed while also achieving high-speed movement and exciting gameplay moments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical parameters such as rotational speed, acceleration, and energy transfer through the use of springs and mechanical components. By controlling and varying these parameters, the system achieves both stable rotation and high-speed movement, resolving the contradiction between stability and speed.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the top toy contacts the protruding wall and slides along it, then the top toy can change direction, but the movement remains within a predictable range

Engineering Contradiction:
Improvemovement rangeVSAvoidpredictability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces sliding with rolling mechanics. The top toy's wheels engage with the protruding wall, allowing the toy to roll along the wall's surface. This rolling interaction, combined with spring mechanisms, enables the top toy to achieve unpredictable direction changes and movement patterns while maintaining control, thereby expanding the movement range beyond predictable limits.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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 solution allows for increased speed and varied movement patterns of top toys, providing more engaging and dynamic gameplay by effectively transmitting rotational energy through engaging teeth and frictional resistance.

Implementation Method 1

When the second teeth are engaged with the first teeth, the top toy rolls along the guide member without sliding, so can be moved effectively. When the second gear is fixed to the body, by engagement of the second teeth and the first teeth, the rotation of the top toy is transmitted to the guide member

Methodology Applied
Scientific EffectGear engagement: Gear

Implementation Method 2

the top toy rolls along the guide member without sliding

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 3

Because the resistance means are provided, the rotation of the top toy is transmitted to the first teeth of the guide member via the teeth forming member, so it is possible to increase the speed at which the top toy moves around

Methodology Applied
Scientific EffectFrictional resistance: Friction

Implementation Method 4

When the gear collides with the guide member, the gear is rotated in resistance to the energizing force of the plate spring in the direction that mitigates impact on the rotation shaft, so the impact is effectively absorbed

Methodology Applied
Scientific EffectElastic deformation: Elasticity

Implementation Method 5

the energizing force of the plate spring in the direction that mitigates impact on the rotation shaft

Methodology Applied
Scientific EffectSpring: Spring

AI summary

This is a top toy that is used together with a guide member on which are formed a plurality of first teeth at equal intervals in the lengthwise direction, and that comprises a body configured from a shaft part and a trunk part, and the top toy is characterized by comprising a teeth forming member on which a plurality of second teeth that are engageable with the first teeth are formed at equal intervals on the outer periphery of the body. As a result, it is possible to effectively move the top toy along the guide member, and to change the movement by the amount of engagement of the second teeth and the first teeth.
