Rotatable Hand Shower Head for Compact Water Jet Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand showers with fixed orientation require active user intervention to change the direction of the water jet, are cumbersome, and not suitable for users with reduced mobility, often increasing dimensions and discomfort.
Innovation Solution
An orientable hand shower design with a rotatable head and handle pipe connection, allowing 180-degree rotation and sealed engagement, facilitated by a snap-fit elastic connection and abutment element for easy maneuverability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the head and handle pipe are made as a single unit with fixed orientation, then the manufacturing is simple and structure is compact, but the water flow direction cannot be adjusted without active user intervention
Solution Approach 1:
The patent applies the dynamics principle by making the head rotatable relative to the handle pipe through a threaded connection mechanism. The head can be manually rotated to change the water flow direction and then locked in position, transforming a static fixed-orientation structure into a dynamic adjustable one. This resolves the contradiction by enabling water flow direction adjustment without requiring complex control valves or multiple components.
2Adaptability or versatility
If additional accessories are added to expand the orientation of the jet, then the water flow direction versatility is improved, but the overall dimensions increase and cause discomfort
Solution Approach 1:
The patent applies segmentation by separating the orientation adjustment function from the main handle pipe body. The head is designed as a separate, rotatable component that can independently change direction without increasing the size of the handle pipe. This allows water flow direction versatility to be achieved while keeping the overall dimensions compact and comfortable for user handling.
3Ease of operation
If the hand shower is inserted into a fixed shower support, then the installation is simple, but the water flow remains constrained to the shower structure and cannot be directed freely
Solution Approach 1:
The patent applies dynamics by incorporating a rotatable head mechanism that allows the water flow direction to be changed even when the handle pipe is installed in a fixed shower support. The threaded connection between the head and handle pipe enables manual rotation and locking at different angles, providing free direction control without compromising the simple installation of the fixed support structure.

AI summary
An orientable hand shower (100) comprises a head (1) and a handle pipe (2), both having an axisymmetric extension about the respective head axes T and pipe axis C. The head (1) is suitable for rotating about the pipe (2) with respect to a rotation axis (X), perpendicular to the head base (11) and to the pipe base (21) and inclined with respect to the head axis (T) by a head inclination angle (Δ) and with respect to the pipe axis (C) by a pipe inclination angle (µ). The orientable hand shower (100) further comprises an abutment element (3) interposed between the head (1) and the pipe (2) and comprising an upper base (31), facing the head (1), and a lower base (32), facing the pipe (2), parallel and offset therebetween.
