Solution Overview
Problem
Existing water display technologies fail to consistently maintain laminar flow characteristics of water jets, leading to turbulence and breakup into droplets, which affects the aesthetic and structural integrity of the water bell shape.
Innovation Solution
A water display system utilizing a laminar nozzle and impactor configuration that maintains low turbulence by ejecting a laminar jet perpendicular to an impactor, supported by rigid structures, and optionally incorporating a burner for flame integration, to create stable and dynamic bell-like water displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional water display technologies are used, then water jets can be produced, but laminar flow characteristics cannot be consistently maintained, leading to turbulence and breakup into droplets
Solution Approach 1:
The water display system is segmented into distinct functional components: a water supply system with flow control, a laminar flow generator (nozzle assembly), a support structure, and an optional impactor. This segmentation allows each component to be optimized independently for maintaining laminar flow, with the nozzle specifically designed to produce a stable laminar sheet that forms the water bell.
Solution Approach 2:
The nozzle assembly is designed with specific local characteristics to maintain laminar flow, including a controlled exit geometry and optional heating element positioned at the nozzle exit. The impactor (when used) has a specific geometry with a sharp edge to cleanly intersect the laminar sheet. These localized quality enhancements ensure laminar flow is maintained at critical points in the system.
2Stability of the object's composition
If rigid support structures are used to maintain nozzle position, then structural stability is improved, but device complexity increases
Solution Approach 1:
The support structure provides rigid stabilization specifically at the nozzle assembly and impactor mounting points, while other parts of the system remain simpler. The support structure includes a rigid mounting for the nozzle and, when used, the impactor, ensuring these critical components maintain precise positions and orientations without requiring complex overall system design.
3Illumination intensity
If burner integration is added to create flame displays, then visual appeal is enhanced, but device complexity and safety requirements increase
Solution Approach 1:
The burner assembly is merged with the water display system, positioned to project flames through or alongside the water bell. The burner is integrated into the existing support structure, sharing mounting points and control systems where possible. This merging creates a combined water-and-flame display that leverages the visual appeal of both elements while avoiding the need for completely separate systems.
Solution Approach 2:
The support structure and control system are designed to accommodate multiple functions: water delivery, flame generation, and optional impactor positioning. The burner assembly can operate independently or in combination with the water display, providing versatility. The system can switch between water-only mode, flame-only mode, or combined mode, making it adaptable to different display requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively maintains laminar flow characteristics, producing stable and aesthetically pleasing bell-like water shapes, with the option to incorporate flames within or breaking through the water bell, enhancing visual appeal.
Implementation Method 1
A water display system utilizing a laminar nozzle and impactor configuration that maintains low turbulence by ejecting a laminar jet perpendicular to an impactor
Implementation Method 2
The force of gravity pulls the water in a downward direction and the laminar sheet of water assumes a bell-like shape
Implementation Method 3
The impactor intercepts the laminar jet and redirects water flow horizontally, creating a sheet of water that extends from the impactor substantially horizontally and symmetrically in all directions

AI summary
A decorative water display provides a laminar water bell. A gas burner may be provided inside the laminar water bell to produce a decorative flame. A laminar nozzle having an outlet arranged to eject a laminar jet of water upwardly in a substantially vertical direction may strike an impactor suspended directly above the outlet of the laminar nozzle such that the laminar jet of water forms the laminar water bell. Alternatively, a vertical pipe may supply water to a thin annular region between two plates such that water flowing between the two plates assumes a generally laminar flow characteristic and forms the laminar water bell when ejected from between the two plates. Alternatively, a hemispherical nozzle may have a slot arranged to eject a sheet of water upwardly to form a segment of the laminar water bell.
