Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spinning top toys with a reversed conical lower member suffer from issues such as wall contact and wide movement when rotated on a game board with varying wall heights, leading to instability and unpredictable behavior.
Innovation Solution
A spinning top toy design featuring a shaft part with a wheel-shaped ground contact member that can be manually switched between two positions, allowing for controlled contact with the surface, enabling switching of rotation characteristics and travel modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the lower member is formed in an approximately reversed conical shape with low height, then the ground contact surface can be reduced for rotation, but the lower member will contact and strand on walls or hit walls causing the spinning top to flick out
Solution Approach 1:
The patent applies the dynamics principle by making the lower member height adjustable rather than fixed. The lower member can be raised or lowered relative to the rotary plate, allowing the ground contact surface area to be dynamically changed. This resolves the contradiction by enabling the user to adjust the lower member height according to wall conditions: lowering it to reduce ground contact for rotation, or raising it to prevent wall contact and ensure stable spinning.
2Speed
If the lower member height is low, then rotation is improved, but when the ground contact surface has inclination, the lower surface is easily grounded causing wide movement
Solution Approach 1:
The adjustable lower member height provides dynamic control over the spinning top's behavior. When high rotation speed is needed on flat surfaces, the lower member can be lowered. When stability on inclined surfaces is needed, the lower member can be raised to prevent the lower surface from grounding and causing wide movement. This dynamic adjustment resolves the contradiction between rotation speed and position stability.
3Reliability
If the lower member is raised to prevent wall contact, then stability improves, but the ground contact surface area increases reducing rotation performance
Solution Approach 1:
The patent resolves this contradiction through dynamic adjustment of the lower member height. Users can raise the lower member to prevent wall contact and improve stability, or lower it to reduce ground contact surface area and enhance rotation speed. The system adapts to different operational requirements by allowing height adjustment, thus resolving the trade-off between stability and rotation performance.
