Expandable Hose Regulator Assembly for Burst Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional expandable hoses burst under high water pressure from spigots, which is unnecessary for operating lawn and garden accessories, and existing solutions do not effectively regulate pressure.
Innovation Solution
A hose design featuring a regulator assembly that reduces fluid pressure from spigot levels to a manageable range (60-80 PSI) using a valve system with a spring-biased valve stem and seat, coupled with a hose assembly comprising inner and outer members connected by tube connectors and collars to prevent bursting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional expandable hoses are used without pressure regulation, then the hose can withstand high water pressure from spigots, but the high pressure causes the hose to burst and is unnecessary for operating lawn and garden accessories
Solution Approach 1:
A regulator assembly is introduced as an intermediary component between the spigot and the hose. This regulator assembly includes a valve mechanism with a valve stem, valve seat, and spring that actively reduces high spigot pressure to a manageable range (60-80 PSI) before water enters the hose, preventing bursts while maintaining reliable operation
Solution Approach 2:
The regulator assembly changes the pressure parameter of the fluid flowing through the system. By using a spring-biased valve mechanism, the system dynamically adjusts and maintains water pressure within a safe operating range (60-80 PSI), transforming the harmful high-pressure state into a safe low-pressure state that prevents hose bursting
2Reliability
If a regulator assembly is added to reduce pressure, then the hose is protected from bursting, but the device complexity increases
Solution Approach 1:
The hose system is segmented into distinct functional components: the spigot connector, the regulator assembly (with valve stem, valve seat, spring, and housing), and the hose itself. This segmentation allows the complex pressure-regulation function to be isolated in a dedicated module that can be manufactured, tested, and replaced independently, making the overall system more manageable despite the added complexity
Solution Approach 2:
The regulator assembly serves multiple functions: it reduces pressure, prevents hose bursting, and provides a controllable water flow to the hose. By consolidating these functions into a single multi-functional component, the patent avoids adding separate devices for each function, thereby minimizing the increase in overall device complexity while achieving reliable pressure protection
