Hand Shower with Rotatable Head for Adjustable Water Flow Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand showers lack the ability to easily adjust the angle of water flow relative to the handle, limiting user flexibility in directing the water stream.
Innovation Solution
A hand shower design featuring a rotatable shower head that can be positioned between two angularly spaced positions, allowing the water outlets to change the angle of water spray relative to the handle, with a detent device for secure locking in each position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shower head is fixed in a single position, then the device structure is simple, but the user flexibility in directing water flow is limited
Solution Approach 1:
The shower head is made rotatable relative to the handle, allowing it to change position dynamically between a first position and a second position that are angularly spaced apart. This dynamic adjustment capability enables users to direct water flow at different angles without requiring a completely complex reconfigurable structure.
Solution Approach 2:
The connection between the shower head and handle is segmented into a rotatable joint with detent positions, separating the fixed handle from the adjustable shower head. This segmentation allows independent optimization of each component while providing controlled adjustability through discrete angular positions.
2Adaptability or versatility
If the shower head can rotate freely, then user flexibility is maximized, but the shower head may become unstable or misaligned
Solution Approach 1:
Detent devices are pre-positioned at specific angular locations to automatically guide and secure the shower head in predetermined stable positions. This preliminary positioning mechanism prevents random rotation and ensures the shower head settles into reliable, repeatable orientations during use.
Solution Approach 2:
The rotational degree of freedom is constrained by changing the parameter of angular position to discrete detent positions. This transforms continuous rotation into controlled angular steps, maintaining stability while preserving adjustability between the first and second angularly spaced positions.
3Ease of operation
If the shower head is made rotatable with detent positions, then usability is improved, but the manufacturing complexity increases
Solution Approach 1:
A rotatable connection with detent positions is implemented between the shower head and handle, allowing the shower head to be easily rotated to different angular orientations. The detent mechanism provides tactile feedback and secure positioning at discrete angles, enhancing usability without requiring complex control systems.
Solution Approach 2:
The rotatable connection is segmented into discrete detent positions, simplifying the manufacturing of each component while enabling controlled angular adjustment. This segmentation allows standard manufacturing techniques to produce the handle, shower head, and detent mechanism as separate, manufacturable parts that assemble together.

AI summary
A hand shower including a handle with a first waterway including an inlet portion and an outlet portion, the inlet portion configured to be fluidly coupled to a water supply. A shower head includes a second waterway having an inlet portion and an outlet portion. The inlet portion of the second waterway is fluidly coupled to the outlet portion of the first waterway, and the outlet portion of the second waterway includes a plurality of outlets configured to deliver water. The shower head is supported for rotation about a longitudinal axis of the handle between a first position and a second position angularly spaced from the first position.
