Shower Head Fluid Chamber Layout for Slim Multi-Spray Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower heads with multiple groups of spray nozzles require a large height and result in significant residual water after shutdown, leading to undesirable dripping and high water consumption.
Innovation Solution
A shower head design with a cavity divided into laterally separated fluid chambers by a partition structure, featuring main and branch channels that allow for a compact, slim profile, reduced dripping, and efficient water distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fluid connections are arranged on different planes (one above the other), then multiple groups of spray nozzles can be supplied, but the shower head height becomes large and residual water increases
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (one dimension) to a lateral arrangement within a single plane (another dimension). The partition structure divides the cavity into laterally separated fluid chambers, allowing multiple fluid connections to be arranged side-by-side rather than one above the other, thereby reducing shower head height while maintaining multiple spray patterns.
2Adaptability or versatility
If fluid connections are arranged on different planes, then multiple groups of spray nozzles can be supplied, but residual water increases leading to undesirable dripping
Solution Approach 1:
By arranging fluid chambers laterally in a single plane rather than vertically stacking them, the patent reduces the volume of the base body cavity and minimizes residual water accumulation, thereby reducing dripping while maintaining multiple spray patterns.
3Length of stationary object
If a compact, slim design is achieved, then shower head height is reduced, but fluid connection arrangement becomes more difficult
Solution Approach 1:
The patent segments the base body cavity into multiple laterally separated fluid chambers using a partition structure. This segmentation allows each chamber to be independently arranged in a lateral configuration, simplifying the fluid connection arrangement within a compact, slim shower head design.

AI summary
1. Shower head. 2.1. The invention relates to a shower head with a base body having a shower fluid inlet, a spray disc unit (3) located on a shower jet outlet side of the base body and having several fluid-separated groups of shower jet outlet openings (5, 6), and several fluid connections (7, 8) from the shower fluid inlet to each of the groups of shower jet outlet openings (5, 6). 2.2.According to the invention, a cavity (9) is formed in the base body, bounded by a chamber floor and a chamber ceiling, which is divided into several laterally separated fluid chambers (19, 20) by a fluid-tight partition structure (23) between the chamber floor and the chamber ceiling, wherein the first group of shower jet outlet openings (5) is in fluid communication with a first (19) of the fluid chambers (19, 20) and the second group of shower jet outlet openings (6) is in fluid communication with a second (20) of the fluid chambers (19, 20).Furthermore, the first fluid chamber (19) has one or more first main channels (15, 15i, 152) extending from an inlet (13) into the first fluid chamber (19) and at least two adjacent first branch channels (141, 142) extending from the one or from at least one of the several first main channels (15, 15i, 152), wherein the two adjacent first branch channels (141, 142) or two adjacent areas (B11, B12) of the first fluid chamber (19) supplied by two of the first main channels (15) are arranged laterally spaced apart from each other by an intermediate area (B2) of the second fluid chamber (20). 2.3. Use e.g. as a sanitary hand shower or overhead shower or side shower.
