Solution Overview

Problem

Existing water display systems are bulky, heavy, and labor-intensive to align, with limited nozzle positioning flexibility, making them inefficient for creating complex and varied displays.

Innovation Solution

A compact fluid effects apparatus with a center point gimbal and drive assembly using submersible servos to pivot a fluid outlet manifold, allowing up to 55 degrees of motion in any direction, and a self-managing hose assembly to reduce weight and improve alignment accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing water display devices use large movable platforms with multiple assemblies to articulate nozzles to numerous positions, then the nozzle positioning flexibility and display variety are improved, but the system size and weight increase significantly

Engineering Contradiction:
Improvenozzle positioning flexibilityVSAvoidplatform weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The system divides the articulation function into two independent parts: (1) a movable platform that provides vertical positioning, and (2) a fixed base with a gimbal mechanism that provides angular articulation. This segmentation allows the heavy platform to be smaller while the articulation function is handled by a compact gimbal assembly, reducing overall system weight while maintaining full positioning capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a two-assembly articulation system (requiring rotation about two perpendicular axes on the platform) to a single-gimbal system that achieves the same angular positioning through a different geometric configuration. The gimbal mechanism uses a spherical joint that naturally provides multi-axis rotation capability in a more compact form factor.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If existing water display devices use large movable platforms with multiple assemblies, then the nozzle can articulate to numerous positions, but the equipment required to raise and lower the platform becomes bulky

Engineering Contradiction:
Improvenozzle articulation rangeVSAvoidequipment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system separates the vertical positioning function (handled by the movable platform) from the angular articulation function (handled by the gimbal). This allows each subsystem to be optimized independently, resulting in simpler, less bulky equipment for each function while maintaining comprehensive nozzle positioning capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of mounting the articulation assemblies on the movable platform (as in existing systems), the invention inverts the configuration by placing the gimbal mechanism on the fixed base. This inversion allows the platform to be simpler and lighter, while the articulation function is provided by the base-mounted gimbal.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of manufacture

If workers manually align nozzles by hand in water during shows, then alignment can be performed without complex equipment, but the alignment process is labor intensive and inaccurate

Engineering Contradiction:
Improvealignment simplicityVSAvoidnozzle alignment accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The system includes a homing mechanism that automatically returns the nozzle to a predetermined home position (typically vertical) before each show or after disturbances. This preliminary action ensures accurate alignment without requiring manual intervention, improving both precision and reliability while maintaining operational simplicity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The gimbal mechanism is designed with inherent alignment features that allow the nozzle to self-align to the vertical home position through gravity or mechanical guidance. This self-service capability eliminates the need for labor-intensive manual alignment while maintaining high positioning accuracy.

Inventive Principle:
Principle #25Self-service

AI summary

A fluid effects apparatus (100) to produce a fluid display or effect. The apparatus (100) includes a base (112) with a center point gimbal (122). A fluid outlet manifold (130) is provided with an inlet (134) for receiving fluid and an outlet device (144) such as a nozzle for dispersing the received fluid. The fluid outlet manifold (130) is supported upon the center point gimbal (122) to pivot with the gimbal in all directions. A drive assembly (160) is provided with first and second drive mechanisms (162,163) such as submersible servos that each drive input arms (172,173) attached to the fluid outlet manifold (130) at an angular offset such as about 120 degrees. The drive mechanisms (162,163) are separately and concurrently operable to move the input arms (172,173) to pivot the fluid outlet manifold (130) on the center point gimbal (122) to selectively position the outlet device (144) such as to articulate it in arcs of 110 degrees or more in all directions about a nozzle center axis.
