Innovation Solution
A multi-axis movable tumbling arrangement incorporating a length-adjustable guide mechanism and multi-axis wobble bearing, which includes a passive guide device that follows the wobble support's movements, preventing lateral sliding and allowing for both wobbling and linear adjustments, including height adjustments, with a design that minimizes collisions and enhances passenger access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional wobble assembly with hydraulic cylinders is used, then the wobble movement is generated, but unwanted lateral sliding movements occur and the kinematic range is limited
Solution Approach 1:
A guide mechanism is introduced as an intermediary between the wobble beam and the drive mechanism. This guide mechanism includes guide elements that constrain the wobble beam to follow a predetermined wobble path, preventing unwanted lateral sliding movements while allowing the desired wobble motion to occur.
Solution Approach 2:
The wobble assembly is designed with multi-axis movability, allowing the wobble beam to dynamically adjust its position and orientation within controlled limits. The system transitions from a fixed constraint to a dynamic constraint that permits legitimate motion while preventing harmful deviations.
2Adaptability or versatility
If the wobble beam is installed in a silo or scenery environment, then the entertainment value is enhanced, but collisions with the surrounding structure occur
Solution Approach 1:
The guide mechanism is designed with predetermined wobble paths that are calculated in advance to ensure the wobble beam remains within safe clearance distances from the silo or scenery walls. By pre-planning the motion trajectory, collisions are prevented before they can occur.
Solution Approach 2:
The guide mechanism acts as a mediator between the wobble beam and the surrounding environment, constraining the beam's motion to a safe corridor that maintains appropriate clearance from the silo or scenery structure throughout the wobble cycle.
3Device complexity
If a passive guide device is used, then the device complexity is reduced, but the guide mechanism must follow the wobble support movements
Solution Approach 1:
The passive guide device utilizes the wobble support's own movements to drive the guide mechanism. The guide elements are designed to automatically follow and constrain the wobble beam's motion without requiring external power or active control systems, making the guide device self-regulating.
