Bubbler Flow Controller Structure for Stable High-Pressure Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow controllers in bath products fail to maintain stable water flow under varying water pressures, leading to potential damage and reduced service life when water pressure exceeds the clamping jaws' limit.
Innovation Solution
A flow controller design featuring a shell with a sheet part supported by elastic legs, including support legs and suspension legs, which share pressure stages to distribute water pressure, preventing leg fracture and extending service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping jaws are used to support the elastic body, then the flow controller can maintain stable water pressure under normal conditions, but the clamping jaws will break when water pressure exceeds the pressure limit
Solution Approach 1:
The support structure is segmented into multiple elastic legs (at least three) distributed across the sheet part, rather than relying on a single clamping jaw. This segmentation distributes the water pressure across multiple support points, preventing any single point from bearing excessive load and breaking.
Solution Approach 2:
The support structure transitions from a single-plane clamping jaw to a three-dimensional arrangement of multiple elastic legs extending from the sheet part to the bottom of the shell. This spatial distribution in multiple dimensions enhances the overall pressure-bearing capacity while maintaining flexibility.
2Strength
If a single support structure is used, then the device complexity is low, but the water pressure-bearing capacity is limited and legs may fracture under high pressure
Solution Approach 1:
Each elastic leg serves multiple functions: providing support, absorbing pressure, and maintaining the gap between the sheet part and the shell bottom. This multi-functionality allows the use of simple elastic leg structures rather than complex specialized components, achieving high pressure-bearing capacity without proportionally increasing device complexity.
Solution Approach 2:
The number of elastic legs is set to at least three, changing the structural parameter from single-point or two-point support to multi-point support. This parameter change significantly increases the pressure-bearing capacity and reliability while maintaining relatively simple individual leg structures.
