Solution Overview
Problem
Conventional yo-yos have limited sleep time, restricting the duration of tricks that can be performed, and existing electrically powered yo-yos consume excessive energy to maintain extended sleep times.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an electrically powered rotation system is used to extend sleep time, then the duration of action is improved, but energy consumption increases
Solution Approach 1:
The powered rotation system operates periodically rather than continuously, with the electromagnet engaging the magnet at specific intervals during the yo-yo's rotation to provide timed boosts of rotational energy, minimizing overall power consumption while maintaining extended sleep time
Solution Approach 2:
The system changes operational parameters by adjusting the timing and duration of electromagnet activation based on the yo-yo's rotational state, optimizing energy delivery to extend sleep time without excessive power consumption
2Power
If board assembly is made heavy to provide mass for electromagnet to push, then rotational momentum is improved, but weight increases
Solution Approach 1:
The circuit board is designed with an asymmetric, non-symmetric shape that creates an offset center of gravity, providing the necessary mass for the electromagnet to push against while minimizing overall weight compared to a symmetric design of equivalent mass
3Ease of manufacture
If symmetric circuit board is used, then manufacturing is simplified, but rotational efficiency decreases
Solution Approach 1:
The circuit board employs a non-symmetric shape that offsets the center of gravity from the rotation axis, creating a more effective lever arm for the electromagnet to push against, thereby improving rotational efficiency and power delivery despite increased manufacturing complexity
