Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow limiters fail to maintain a consistent and accurate flow rate across varying pressures, leading to inefficiencies in water usage and increased costs in managing peak demands, particularly in showers and industrial applications.
Innovation Solution
A device comprising a housing with a partition and flow limiting elements, featuring a disc-shaped partition with multiple openings and a resilient valve element that maintains a constant flow rate by adjusting to pressure changes, ensuring precise control over fluid flow through a unique valve seat design and cam parts, allowing for adaptable flow rates and precise dimensioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flow limiters are used, then flow rate can be limited, but flow rate consistency across varying pressures deteriorates
Solution Approach 1:
The flow limiter incorporates a resilient valve element that dynamically adjusts the flow opening in response to pressure changes. The valve element moves between a first position (higher flow rate) and a second position (lower flow rate) based on upstream pressure variations, maintaining consistent flow rate across different pressure conditions through automatic dynamic adaptation.
2Measurement precision
If flow limiters are installed at many locations, then peak load determination precision improves, but installation costs increase
Solution Approach 1:
The flow limiter automatically determines and communicates peak load information without requiring complex external monitoring systems. The device itself performs the measurement and data transmission functions, eliminating the need for additional sensors, data collection infrastructure, and centralized processing systems that would otherwise be required.
3Adaptability or versatility
If resilient valve elements are used, then flow rate adaptability to pressure changes improves, but manufacturing precision requirements increase
Solution Approach 1:
The invention allows adjustment of the resilient valve element's rest position through modified dimensioning parameters. By changing the rest position, the flow rate characteristics can be optimized for different applications and pressure ranges, enabling the same basic design to serve multiple purposes while maintaining adaptability to pressure variations.

AI summary
A device for limiting or keeping constant a quantity of fluid flowing therethrough, includes: a housing with a front chamber and a rear chamber; a partition arranged in the housing with two or more openings; and a flow limiting element arranged in one or both openings. The flow limiting element includes a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate-like valve element mounted in the housing, substantially able to close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening. The valve element is fixed on one side and can move resiliently on the opposite side in the direction of the valve seat. A mould produces one or more injection-moulded products. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough.
