Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid diffuser devices face issues with nozzle replacement in contaminated environments due to foreign matter accumulation, leading to unstable connections and accidental disengagement, making replacement difficult and prone to loss.
Innovation Solution
A diffuser device with a partly hollow support body and connection sleeve, featuring primary connection means such as projections and recesses for secure attachment of the nozzle, ensuring a firm connection and easy replacement without accidental separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If snap connection means are used to hold the nozzle in position, then the nozzle can be easily mounted and removed, but foreign matter accumulates in the recess of the snap means causing connection deterioration and accidental disengagement
Solution Approach 1:
The connection system is divided into two independent parts: snap connection means for easy mounting/removal operation, and primary connection means (projections and recesses) for reliable positional holding. This segmentation allows each part to specialize in one function without interference from foreign matter accumulation in a single connection interface.
Solution Approach 2:
The projections on the nozzle are designed to be inserted into corresponding recesses in the support body before the snap connection is fully engaged. This preliminary action establishes a stable positional relationship that prevents accidental disengagement, while the snap means provides the final secure attachment for easy operation.
2Ease of operation
If the nozzle is securely held by snap means, then replacement is simple, but the recess fills with foreign matter making removal and remounting difficult
Solution Approach 1:
The connection mechanism is segmented into snap means for operational simplicity and primary connection means with projections for preventing foreign matter interference. This division maintains replacement simplicity while adding reliability without significantly increasing overall complexity.
Solution Approach 2:
The projections act as intermediary elements between the nozzle and support body, providing a mechanical interface that is less susceptible to foreign matter accumulation compared to recess-based snap connections. This intermediary structure simplifies the overall connection process while maintaining ease of operation.
3Reliability
If the nozzle connection deteriorates, then accidental disengagement occurs causing nozzle loss, but strengthening the connection increases device complexity
Solution Approach 1:
The connection system separates retention function (projections in recesses) from attachment function (snap means). This segmentation achieves high reliability for nozzle retention without requiring a single complex connection mechanism, thereby avoiding excessive device complexity.
Solution Approach 2:
The projection-recess primary connection means is merged with the snap connection means to create a dual-function connection system. This merging achieves both high reliability and simplicity, as the projections prevent accidental disengagement while the snap means provides secure attachment, without requiring separate complex mechanisms.

AI summary
This invention finds application in the field of liquid distributing devices, and particularly relates to a sprinkler head device, particularly for use in sprinkler systems for distributing liquids or the like. The device comprises a support body (2) to be removably coupled to a sleeve (3) for connection to an external liquid supply line, a convergent nozzle (8) between the body (2) and the sleeve (3) and a diverter member (9) downstream from the nozzle (8) for diverting flow and sprinkling fluid out. The device further includes main connection means (16) for removably attaching the nozzle (8) to the support body (2) while preventing any accidental separation thereof upon mutual coupling and uncoupling of the sleeve (3) to the body (2), thereby allowing fast and easy periodic replacement of the nozzle (8).
