Swing Device Fulcrum Positioning for Vertical Motion Sensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swing devices struggle to enhance the realism and impressiveness of rising or lowering feelings for users due to their complex structures and increased size or cost, which are exacerbated by the need for multiple driving points and increased degrees of freedom.
Innovation Solution
A swing device with a fulcrum support mechanism placed on the rear side of the user and a first driving mechanism at a driving point spaced apart in the longitudinal direction, allowing vertical movement to create a synergistic effect that enhances the sensation of rising or lowering by tilting the swing member, while maintaining a simple structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of driving points is increased or the degree of freedom of driving directions is increased, then the user can body-sense a rising or lowering feeling more impressively, but the size and cost of the machine increase
Solution Approach 1:
The patent combines the fulcrum support mechanism and the first driving mechanism into a coordinated system where the fulcrum is positioned on the rear side of the user and the driving point is positioned on the front side, creating a synergistic effect that enhances the rising/lowering sensation without requiring multiple independent driving systems
Solution Approach 2:
The patent introduces vertical movement of the fulcrum as an additional degree of freedom, transforming the traditional horizontal swing mechanism into a three-dimensional motion system that provides more realistic rising and lowering sensations without proportionally increasing complexity
2Stability of the object's composition
If the fulcrum is placed on the front side of the seat and driving points are placed on the rear side, then the swing member can be supported, but the vertical movement of the user's body position contradicts the intended rising or lowering sensation
Solution Approach 1:
The patent inverts the traditional configuration by placing the fulcrum on the rear side of the user and the driving point on the front side, which reverses the direction of vertical movement to align with the intended sensation - when the front is pushed down, the user's body naturally rises, creating the correct rising sensation

AI summary
To provide a swing device capable of making a user body-sense a rising, lowering, and/or turning feeling more impressively or with higher reality with a simple structure, there is provided a swing device including: a swing member (20) on which a user rides; a fulcrum support mechanism (30) for swingably supporting the swing member (20) at a fulcrum (32b); and a first driving mechanism (41a, 41b) for swingably supporting a first driving point (23a, 23b) on the swing member (20) and moving the first driving point (23a, 23b) in a vertical direction, the first driving point (23a, 23b) being spaced apart from the fulcrum (32b) in a longitudinal direction of the swing member (20), characterized in that the fulcrum (32b) is placed on a rear side of a riding position (24) of the user (O) in the longitudinal direction of the swing member (20).
