Spring-Cushioned Jumping Ball Roller for Smooth Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rigid connection between the roller and the rod-like structure in current jumping balls leads to intermittent impacts, causing radial forces that result in wobbling and increased friction, reducing the rotational flexibility of the roller over time.
Innovation Solution
A luminous jumping ball design featuring a connecting rod connected to a rotatable sleeve via a spring, allowing the roller to rotate smoothly by acting as a cushion during collisions, with integrated light-emitting assemblies and optional Bluetooth connectivity for interactive play.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the roller and rod-like structure are rigidly connected, then the structure is simple and strong, but the roller experiences radial forces causing wobble and increased friction, reducing rotational flexibility
Solution Approach 1:
The patent changes the connection parameter from rigid to flexible by introducing a spring mechanism. The spring allows the roller to maintain structural connection while accommodating radial forces through elastic deformation, preventing wobble and friction increase, thus maintaining rotational flexibility without sacrificing structural strength.
2Device complexity
If the roller and rod-like structure are rigidly connected, then the assembly is simple, but the roller wobbles over time creating increased assembly clearance and friction
Solution Approach 1:
The spring mechanism acts as a beforehand cushioning element that anticipates and absorbs radial forces before they can cause wobble or assembly clearance. By providing pre-compression or pre-tension in the spring, the system prevents the development of harmful gaps and maintains reliable rotational stability over time.
3Reliability
If a spring connection is used between the connecting rod and roller, then the roller rotational smoothness and service life are improved, but the device complexity increases
Solution Approach 1:
The spring serves as an intermediary element between the connecting rod and roller. This mediator absorbs the harshness of direct rigid contact while transmitting necessary forces, thereby extending roller service life and improving rotational smoothness. The spring's simple coiled structure provides this mediating function without introducing excessive complexity to the overall mechanism.

AI summary
A luminous jumping ball includes a connecting rod, an ankle ring, and a roller. The ankle ring is fixedly connected to an end of the connecting rod, another end of the connecting rod facing away from the ankle ring is rotatably connected to a rotatable sleeve, the rotatable sleeve is fixedly connected to the roller through a spring, two ends of the spring are fixedly connected to an end of the rotatable sleeve and an end of the roller, respectively, and the spring, the rotatable sleeve, and the roller are coaxially arranged. The connecting rod and the roller are connected through the spring. When the roller collides with the ground, the spring acts as a cushion to prevent damage caused by rigid connection during the collision, thereby increasing a service life of the jumping ball and a smoothness of rotation of the roller.
