Rotatable Combination Shower Head for Even Spray Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination shower heads suffer from uneven water spraying due to separate zones formed by the top and handheld shower heads, leading to discomfort during long-term use, and the handheld shower head often becomes loose or misaligned, causing overlapping sprays.
Innovation Solution
A combination shower head design featuring a rotatably connected main shower head and handheld shower head, with a duct system that adjusts the included angle between their spraying surfaces to form an integrated, even spraying zone, and includes sealing components to maintain stability and sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the top shower head and handheld shower head are detachably connected to allow individual use, then the handheld shower head can be fully utilized, but the connecting face and corresponding pieces wear out over time, causing the handheld shower head to become loose or misaligned
Solution Approach 1:
The patent implements a rotatable connection mechanism between the top shower head and handheld shower head, allowing dynamic adjustment of the handheld shower head's position and angle. This dynamic connection replaces static detachable connections, enabling the handheld shower head to be firmly fixed in multiple positions while maintaining full utilization. The rotatable joint ensures stable connection without wear-induced loosening.
Solution Approach 2:
The handheld shower head is nested within the top shower head structure, with the handheld shower head's connecting portion inserted into the top shower head's receiving cavity. This nested arrangement provides stable positioning and firm connection, preventing the handheld shower head from becoming loose or misaligned while still allowing it to be fully utilized.
2Adaptability or versatility
If the top shower head and handheld shower head form separate spraying zones, then each can function independently, but the combination of the two spraying zones leads to uneven water spray
Solution Approach 1:
The rotatable connection allows the top shower head and handheld shower head to dynamically adjust their relative positions and angles. Users can rotate the handheld shower head to achieve optimal positioning, ensuring that the two spraying zones combine to form a uniform water spray pattern while maintaining the ability to function independently.
3Adaptability or versatility
If the handheld shower head is frequently picked up and placed down, then it can be fully utilized, but the connecting face and corresponding pieces wear out, causing overlap of water sprays
Solution Approach 1:
The rotatable connection mechanism allows the handheld shower head to be firmly fixed in various positions through rotation, eliminating the need for frequent picking up and placing down. This dynamic fixing maintains alignment precision while enabling full utilization of the handheld shower head.
4Adaptability or versatility
If the main shower head and handheld shower head form an integrated top shower head with fixed angles, then the handheld shower head is fully utilized, but it is hard to adjust the spraying angles
Solution Approach 1:
The patent implements a rotatable connection between the top shower head and handheld shower head, transforming the fixed angle structure into a dynamic adjustable structure. Users can freely rotate the handheld shower head to adjust spraying angles while maintaining the integrated spraying zone, greatly improving ease of operation.

AI summary
A shower head comprises a mounting base, a locating base hinged onto the mounting base, a handheld shower head detachably connected to the locating base and a main shower head connected to the locating base. The main shower head is annular or strip-shaped, and the main shower head can surround the outside of the handheld shower head and jointly form a top shower head with the handheld shower head. The main shower head is rotatably connected to the locating base, to adjust the included angle between the water spraying surface of the main shower head and the water spraying surface of the handheld shower head. There is an access clearance between the inner recessed rim of the main shower head and the outer rim of the handheld shower head.
