Adjustably-Weighted Riser Assembly for Sprinkler Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional riser assemblies for fluid dispensers, especially high-output directional sprinklers, face challenges in stability due to fluid expulsion forces and environmental conditions, leading to complex, costly, and time-consuming installation, maintenance, and removal processes, often requiring concrete piers or burial, which complicates transport and reinstallation.
Innovation Solution
An adjustably-weighted riser assembly with a pressurized fluid reservoir and a signal processor outside the container, featuring a conduit for signal carriers, allowing for stable operation without concrete piers or burial, enabling easy installation, maintenance, and reinstallation with minimal tools and equipment, and using high-density polyethylene for durability and resistance to environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional riser assemblies are stabilized using concrete piers or burial, then stability during fluid expulsion is improved, but installation complexity and time are increased
Solution Approach 1:
The riser assembly incorporates a counterweight mechanism that balances the forces generated by fluid expulsion. The counterweight is positioned to offset the destabilizing forces from high-output directional sprinklers, allowing the riser to remain stable during operation without requiring concrete piers or burial stabilization methods.
Solution Approach 2:
The riser assembly uses a dynamic stabilization system that adapts to varying fluid expulsion forces. The counterweight can be adjusted or repositioned to compensate for different sprinkler outputs and operating conditions, providing stability without permanent installation modifications.
2Stability of the object's composition
If conventional riser assemblies are secured using poured concrete, then stability is improved, but removal and reinstallation difficulty increase
Solution Approach 1:
The riser assembly is designed as a modular, detachable system with segmented components that can be easily separated. The counterweight and riser sections are connected through removable joints, allowing the entire assembly to be detached and reinstalled without damaging concrete structures or requiring complex removal procedures.
Solution Approach 2:
The riser assembly incorporates an intermediary connection system that facilitates easy attachment and detachment. This intermediary mechanism allows the riser to be securely connected during operation but easily removed when needed, eliminating the need for permanent concrete securing methods.
3Stability of the object's composition
If conventional riser assemblies use permanent stabilization methods, then stability is improved, but installation time and cost increase
Solution Approach 1:
By incorporating a counterweight mechanism, the riser assembly achieves stability against fluid expulsion forces without requiring time-consuming concrete pouring or burial processes. The counterweight can be pre-installed and adjusted, significantly reducing installation time compared to traditional permanent stabilization methods.
Solution Approach 2:
The riser assembly allows for parameter changes in the counterweight positioning and configuration to optimize stability for different operating conditions. This flexibility enables rapid installation and adjustment without requiring permanent structural modifications, reducing both installation time and long-term maintenance requirements.

AI summary
Described is a riser assembly for use with a fluid dispenser, such as a sprinkler. The assembly includes a container partially circumscribing a reservoir configured to contain a pressurized fluid, the container having a fluid inlet and a fluid outlet disposed therethrough. The assembly further includes a signal processor situatable outside the container that is configured to receive a signal. The signal processor is operatively connectable to a control valve that is operatively connectable to the fluid dispenser. The control valve is configured to selectively control expulsion of the fluid through the fluid dispenser in response to the signal received by the signal processor.
