Solution Overview
Problem
Conventional motion simulating devices for amusement rides have complex motion mechanisms and high costs due to the use of linear actuators that cannot perform large range motions, leading to increased manufacturing and maintenance expenses.
Innovation Solution
A motion simulating device with a simplified structure featuring a positioning unit, a motion mechanism comprising a pivotable motion arm driven by a first driver, and a carrier unit driven by a second driver, allowing for heave, pitch, and roll motions with a simplified motor and transmission mechanism, reducing costs and enabling larger motion ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If linear actuators are used to drive multi-axial movement of seats, then high degrees of freedom motion is achieved, but the motion range is limited and the structure becomes complicated
Solution Approach 1:
The motion mechanism is segmented into multiple independent pivotable connections: the motion arm pivots relative to the positioning unit about a first axis, and the carrier unit pivots relative to the motion arm about a second axis. This segmentation allows each component to perform simple rotational movements while achieving complex multi-axial motion through combination, reducing overall system complexity while maintaining high degrees of freedom
Solution Approach 2:
The patent employs dynamic pivotable connections throughout the mechanism. The motion arm is pivotably connected to the positioning unit, and the carrier unit is pivotably connected to the motion arm, allowing the system to adapt its configuration during operation. This dynamic structure enables larger motion ranges compared to fixed linear actuator installations while maintaining operational flexibility
2Adaptability or versatility
If linear actuators are used to drive seat movement, then multi-axial motion is achieved, but manufacturing and maintenance costs increase
Solution Approach 1:
The patent replaces expensive linear actuators with simpler, more cost-effective pivotable mechanical connections. The motion mechanism uses standard pivot joints and gravity-assisted motion rather than costly actuated linear mechanisms, significantly reducing manufacturing costs while maintaining the required motion capabilities for simulation effects
Solution Approach 2:
The patent extracts the complex actuation function from the linear actuators and replaces it with passive pivotable connections that rely on gravity and simple drivers. This extraction of the complex actuation requirement allows the use of simpler, cheaper components while still achieving the desired multi-axial motion through the pivotable mechanism
3Ease of operation
If linear actuators are used for seat actuation, then controlled motion is achieved, but the motion range is limited
Solution Approach 1:
The patent transitions from linear actuator-based one-dimensional linear motion to a multi-dimensional rotational system. The first pivot connection allows rotation about a first axis, and the second pivot connection allows rotation about a second axis, enabling the carrier unit to achieve motion in multiple dimensions and significantly expanding the overall motion range compared to linear actuators
