Removable Shower Jet Nozzle for Easy Spray-Type Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower cubicle jets are not easily adjustable after installation, requiring specialized expertise to change the type of water spray from nebulizing to filiform and vice versa, necessitating access to the back of the wall, which is time-consuming and inconvenient.
Innovation Solution
A shower cubicle jet design featuring a removable nozzle with a diffusing ring that can be easily swapped to change the spray type, using a simple Allen wrench for operation, and a snap-fit water supply fitting to secure the end body to the wall without needing to access the back, allowing users to adjust the spray type without professional intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nozzle is fixed in the jet body, then the spray type remains stable and reliable, but the adaptability to change spray types is poor
Solution Approach 1:
The nozzle is divided into a fixed body and a removable insert component. The insert contains the spray-type-defining geometry and can be exchanged while the body remains fixed in the wall, enabling spray type changes without compromising the stable mounting structure.
Solution Approach 2:
The removable nozzle insert is nested within the fixed nozzle body. The insert fits into a receptacle in the body, allowing it to be inserted and secured without removing the entire nozzle assembly from the wall, thus maintaining reliability while enabling adaptability.
2Ease of operation
If the nozzle is made removable for easy replacement, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The nozzle is segmented into a simple fixed body and a separate insert. The body contains only the mounting interface and fluid passage, while the insert contains the spray geometry. This segmentation allows each part to be simple in structure while collectively providing removable functionality.
Solution Approach 2:
The nozzle transitions from a completely fixed state to a dynamically replaceable state through a simple insertion/removal mechanism. The insert can be easily inserted into and removed from the body receptacle, providing dynamic reconfigurability without complex mechanisms.
3Manufacturing precision
If specialized intervention is required to change spray type, then the manufacturing precision is maintained, but the loss of time increases
Solution Approach 1:
Different spray type inserts are pre-manufactured with precise spray geometries. Users can directly install the desired insert without requiring specialized intervention, as the precision has already been built into the insert during manufacturing. This eliminates the need for expert adjustment while maintaining precision.
Solution Approach 2:
Instead of requiring experts to adjust and configure spray parameters, pre-configured inserts with specific spray patterns are created as copies of optimized designs. Users simply select and install the insert corresponding to the desired spray type, maintaining manufacturing precision while dramatically reducing the time and expertise required.

AI summary
A jet for a shower cubicle which is suitable for being applied to a side wall of the shower cubicle is described as having an end body for supplying water to the shower cubicle having a through channel for the water. The jet also includes at least one supply duct to supply pressurised water to the through channel and out a nozzle having an ejection hole to produce a water spray inside the cubicle. for the water communicating with the through channel of the end body. The nozzle is removable from the end body, allowing it to be replaced when the end body is fixed to the wall of the cubicle.
