Transformable Yo-Yo Dual-Form Assembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available yo-yos are non-transformable, leading to reduced interest among children as they cannot change forms, resulting in potential waste when children outgrow or lose interest in them.
Innovation Solution
A transformable yo-yo design featuring a connecting shaft with clamping members that allows assembly from both sides, enabling two distinct forms with different characteristics, allowing for varied play styles and easier operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional yo-yo with fixed assembly structure is used, then the manufacturing is simple, but the adaptability is poor and children lose interest quickly
Solution Approach 1:
The yo-yo is divided into separable components (rotator, connecting shaft, clamping member) that can be assembled and disassembled. The clamping member can be independently positioned on either the first or second rotator, enabling transformation between different assembly forms while maintaining simple manufacturing of individual parts.
Solution Approach 2:
The yo-yo transitions from a static fixed-assembly design to a dynamic transformable design. The clamping member can be moved between different rotators, allowing the yo-yo to change its assembly configuration during use, providing varied playing characteristics while keeping the overall structure relatively simple.
2Adaptability or versatility
If a transformable yo-yo with multiple assembly forms is designed, then the adaptability and趣味性 are improved, but the ease of operation may be reduced due to assembly complexity
Solution Approach 1:
The clamping member is designed to be self-retaining on the rotators through friction or mechanical interference fit. Once positioned on a rotator, it automatically secures itself without requiring additional fastening steps, allowing children to quickly transform between forms during play without complex assembly operations.
Solution Approach 2:
The clamping member is pre-designed with features (such as clamping surfaces or engagement structures) that enable it to be quickly attached to either rotator. This preliminary design of the clamping mechanism allows for rapid transformation without requiring complex real-time assembly operations during play.
3Reliability
If traditional connecting methods are used, then the device complexity is low, but the wear rate is high and service life is reduced
Solution Approach 1:
The traditional threaded screw connection is replaced with a clamping-based mechanical connection. The clamping member applies friction-based holding force to secure the connecting shaft to the rotator, eliminating thread wear and improving reliability. This substitution introduces a slightly more complex clamping mechanism but significantly reduces wear and extends service life.

AI summary
The present invention discloses a transformable yo-yo, comprising two rotators and a connecting shaft, wherein a though hole, into which the connecting shaft is inserted from two directions, is provided in the middle of each of the rotators, and a connecting device, configured to connect and secure the connecting shaft, is provided in the through hole; by moving the connecting device, the securing to the connecting shaft can be released so that the rotators are separated from the connecting shaft; the back sides of the two rotators are oppositely connected to the connecting shaft, and connected and secured through the connecting device to assemble a yo-yo of a first form; and after releasing the securing, the front sides of the two rotators are oppositely connected to the connecting shaft, and secured through the connecting device as well to assemble a yo-yo of a second form. Kids can transform a yo-yo to a different form according to their preferences, and the yo-yo in a different form also has different characteristics. As the characteristics are different, different tricky moves are possible. Kids may play with a yo-yo in more varied ways and have more fun. The transformable yo-yo of the present invention, which is an equivalence to two existing yo-yos, is more cost effective and can gain traction more easily among with kids.
