Funfair Ride Shell with Dynamic Axis Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing funfair ride equipment fails to provide passengers with a continuous, randomly varying ride trajectory without continuity of course, limiting the thrill and unpredictability of centrifugal forces and accelerations.
Innovation Solution
A closed shell, preferably spherical, is designed to rotate unorderedly about a continuously changing axis, supported by a frame with means such as pirouetting wheels or air cushions, allowing for unordered movements and random trajectory changes, while ensuring passenger safety with securely anchored seats and a ballast weight for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shell rotates about a fixed axis, then the ride trajectory is predictable and continuous, but passenger enjoyment and thrill are reduced due to lack of randomness
Solution Approach 1:
The patent applies the dynamics principle by making the rotation axis of the shell changeable rather than fixed. The shell can rotate about any diameter axis, and this axis can continuously change direction during operation. This dynamic adjustment of the rotation axis creates unpredictable and random ride trajectories, thereby improving passenger enjoyment while maintaining mechanical reliability through controlled motion.
2Device complexity
If the shell is constrained to rotate about a fixed diameter axis, then the mechanical structure is simple, but the ride experience lacks variety and excitement
Solution Approach 1:
The patent transitions from one-dimensional rotation about a fixed axis to three-dimensional rotation about any diameter axis. The shell is constrained to rotate about a diameter axis that can point in any direction, adding spatial dimensions to the motion. This dimensional expansion enables diverse and exciting ride trajectories while maintaining relatively simple mechanical constraints through spherical support elements.
3Adaptability or versatility
If the rotation axis changes continuously, then passenger enjoyment increases due to random trajectories, but control and stability become more difficult
Solution Approach 1:
The patent employs a ballast weight fixed to the shell to counterbalance the random motions and maintain stability. The ballast weight acts as a counterweight that helps stabilize the shell's center of gravity, ensuring that the continuous changes in rotation axis do not compromise the overall stability and control of the ride system.
