Concentric Lawn Ornament Frames Driven by Fluid Orifices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lawn and garden ornaments lack efficient mechanisms for fluid distribution and rotation, relying primarily on wind, which may not provide consistent water coverage, especially in calm conditions.
Innovation Solution
A decorative lawn ornament design featuring concentric or non-concentrically arranged inner and outer frames with strategically positioned orifices to discharge fluid both outwardly and inwardly, promoting rotational movement and creating distinct fluid spray zones for enhanced water distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wind-driven mechanisms are used for lawn ornaments, then the structure is simple, but water coverage is insufficient and inconsistent especially in calm conditions
Solution Approach 1:
The ornament is divided into multiple functional segments: an outer frame with fluid discharge orifices for water distribution, and an inner frame for rotational movement. This segmentation allows the fluid-driven mechanism to operate independently of wind conditions, ensuring consistent water coverage while maintaining a manageable structural complexity through modular design.
2Productivity
If fluid discharge orifices are added to drive frame rotation, then rotation and water distribution are improved, but device complexity increases
Solution Approach 1:
The outer frame serves multiple functions simultaneously: it acts as a structural support, a fluid distribution system through its discharge orifices, and a rotational component driven by fluid flow. The inner frame similarly serves as both a structural element and a rotation indicator. This multi-functionality improves water distribution effectiveness while minimizing the need for additional separate components, thereby controlling overall device complexity.
3Area of stationary object
If concentric frame arrangement is used, then rotational movement and spray zone coverage are enhanced, but manufacturing complexity increases
Solution Approach 1:
The inner frame is nested within the outer frame in a concentric arrangement, with the inner frame positioned inside the circular perimeter of the outer frame. Both frames share a common vertical axis of rotation. This nesting configuration maximizes spray zone coverage by creating overlapping fluid discharge patterns from both frames, while the standardized concentric geometry simplifies manufacturing and assembly compared to asymmetric or orbital configurations.
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 design ensures consistent and customizable water coverage by utilizing fluid flow to drive both inner and outer frame rotations, providing unequal yet effective spray zones, even in the absence of wind, thus addressing the limitations of traditional ornaments.
Implementation Method 1
at least one first orifice arranged therein is to discharge a portion of the fluid in a first direction outwardly therefrom to cause rotation of the outer frame
Implementation Method 2
at least one second orifice arranged therein is to discharge a portion of the fluid in a second direction inwardly therefrom to contact a surface of inner frame and thereby cause rotation of the inner frame
Implementation Method 3
The at least one first orifice is configured to direct the fluid to an area on a support surface that creates a first fluid spray zone

AI summary
A lawn or garden ornament having an inner frame and an outer frame. The outer frame is to receive a fluid such that at least one first orifice arranged therein is to discharge a portion of the fluid in a first direction outwardly therefrom to cause rotation of the outer frame, and at least one second orifice arranged therein is to discharge a portion of the fluid in a second direction inwardly therefrom to contact a surface of inner frame and thereby cause rotation of the inner frame.
