Quick-Coupling Water Outlet for Fast Hygienic Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary water outlets require significant assembly and disassembly effort, making frequent replacements, such as those needed in hospitals for hygiene reasons, cumbersome and time-consuming, especially when multiple outlets are involved in irrigation systems.
Innovation Solution
A water outlet design featuring a threadless quick coupling between two movable outlet parts, allowing for rapid assembly and disassembly, and an insert cartridge with a jet regulator and sieve for efficient water flow management, which can be easily inserted and removed from the outlet parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection is used to mount the outlet nozzle and insert cartridge, then the connection is secure and reliable, but the assembly and disassembly effort becomes significant and time-consuming
Solution Approach 1:
The water outlet is divided into separate modular components (outlet nozzle, insert cartridge, jet regulator, strainer) that can be independently assembled and disassembled. The quick-release coupling mechanism enables these segmented parts to be connected and disconnected rapidly without thread engagement, resolving the contradiction between secure connection and quick assembly/disassembly.
Solution Approach 2:
A quick-release coupling mechanism acts as an intermediary between the outlet nozzle and insert cartridge, replacing the traditional screw thread connection. This intermediary component provides both secure mechanical engagement and rapid release capability, eliminating the need for time-consuming threading operations while maintaining connection reliability.
2Ease of manufacture
If the water outlet components are designed as integrated units, then manufacturing is simpler, but replacement and maintenance become more difficult and time-consuming
Solution Approach 1:
The water outlet system is segmented into functionally independent modules (outlet nozzle, insert cartridge, jet regulator, strainer) that can be manufactured separately using optimized processes for each component type, then assembled via quick-release coupling. This segmentation enables both manufacturing efficiency and easy replacement of individual components without affecting other parts.
Solution Approach 2:
The connection between components transitions from a static permanent bond (welding or threading) to a dynamic reversible connection through the quick-release coupling. This allows components to be easily separated and reassembled for maintenance or replacement while maintaining structural integrity during normal operation.
3Strength
If traditional screw connections are used for mounting outlet nozzles, then the structural integrity is maintained, but the complexity of assembly and disassembly procedures increases
Solution Approach 1:
The quick-release coupling serves as an intermediary mechanism that maintains structural integrity through positive mechanical engagement and locking features, while simultaneously providing ease of operation through a simple release mechanism that allows rapid assembly and disassembly without complex threading procedures.
Solution Approach 2:
The quick-release coupling incorporates self-aligning and self-locking features that automatically ensure proper engagement and secure connection when components are assembled, eliminating the need for precise manual alignment or multiple adjustment steps while maintaining strong structural integrity.
