Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swings provide a simple pendulum movement experience, leading to monotony and loss of interest, as they lack 360° rotation and a realistic feeling of riding a swing, combining user power and motor-driven rotation.
Innovation Solution
A swing-type experience apparatus with vertical columns, a driving device featuring a motor and clutch, and rotating shafts that allow for 360° rotation by combining user power and motor-assisted rotation, with a control method switching between help and non-help modes based on rotating shaft direction and angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the seat hangs from the frame through connection parts composed of ropes or chains, then the swing structure is simple, but the experience is simple and the experiencing person easily loses interest
Solution Approach 1:
The patent transforms the static pendulum movement into a dynamic 360° rotation system. The rotating shaft and swing seat assembly can rotate horizontally 360 degrees while maintaining pendulum motion, creating a dynamic multi-dimensional experience that resolves the contradiction between structural simplicity and experience variety.
Solution Approach 2:
The invention adds a horizontal rotation dimension to the traditional vertical pendulum motion. By enabling the swing seat to rotate 360 degrees around the vertical axis while swinging, it creates a two-dimensional motion pattern (vertical oscillation + horizontal rotation) that dramatically enhances experience variety without significantly complicating the overall structure.
2Speed
If the rotating force of the motor is continuously transferred to the rotating shaft, then the 360° rotation is achieved, but the feeling of actually riding on a swing is lost
Solution Approach 1:
The clutch mechanism operates periodically, engaging to provide motor assistance during the upward phase of swing motion and disengaging during the downward phase. This periodic action allows the user to feel the swing's natural motion while receiving supplemental power at appropriate moments, achieving both 360° rotation capability and authentic swing sensation.
Solution Approach 2:
The clutch acts as an intermediary between the motor and the rotating shaft, selectively transmitting motor power only when needed. This mediator component enables the system to switch between motor-driven rotation and user-driven rotation, providing both automated 360° rotation capability and manual control feeling.
3Power
If the clutch is engaged to transfer motor power, then rotation assistance is provided, but energy loss occurs during power transmission
Solution Approach 1:
The clutch engages and disengages periodically based on the swing's motion phase, transferring motor power only during the upward swing phase when assistance is needed. By limiting power transmission to specific phases rather than continuous operation, the system reduces energy loss during power transmission while still providing necessary rotational assistance.
