Top Toy Ride-Over Structure for Varied Rail Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing top toys exhibit monotonous movement patterns due to gear interaction with a rack, leading to repetitive bouncing or immediate acceleration without innovative movement variations.
Innovation Solution
A top toy design incorporating a rotating shaft with a rotor and a ride-over part featuring an axially symmetrical sliding contact surface that allows the top toy to engage with an acceleration rail, enabling innovative movements by floating the landing part above the lower level and facilitating gear meshing with the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the gear meshes with the rack while the top toy remains landed, then the top toy can be accelerated, but the movement becomes monotonous with only bouncing or immediate acceleration
Solution Approach 1:
The patent applies the dynamics principle by making the top toy's body movable relative to the rotating shaft. Specifically, the top toy body can tilt forward when contacting the ramp surface, allowing the gear to engage with the rack at different positions. This dynamic adjustment enables varied movement patterns including floating landings, bouncing, and accelerated motion, resolving the contradiction between acceleration capability and movement variety.
2Speed
If the top toy contacts the rack immediately upon contact, then acceleration occurs, but the movement lacks surprise and innovation
Solution Approach 1:
The patent applies preliminary action by positioning the top toy body in a tilted state before gear-rack engagement occurs. When the top toy contacts the ramp surface, the body is already inclined forward, which causes the gear to engage with the rack at an optimized position. This preliminary tilting action creates surprising and innovative movement patterns while maintaining rapid acceleration, rather than immediate engagement upon contact.
