Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shower jet outlet devices with fine jet openings are prone to clogging by dirt particles and calcification, leading to functional failures and increased cleaning efforts.
Innovation Solution
A shower jet outlet device featuring a pot-shaped jet outlet element with an elastic material composition, including a bottom and side wall that deform under fluid pressure, reducing the likelihood of clogging by allowing easy detachment of dirt and lime particles and promoting self-cleaning through increased fluid pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fine jet openings are provided in the jet disc to produce a fine/needle jet, then the shower jet quality is improved, but the susceptibility to clogging by dirt particles and calcification increases
Solution Approach 1:
The jet outlet element is made of elastic material that can deform dynamically in response to fluid pressure. During normal operation, the element maintains a configuration that provides fine jet openings for high-quality shower output. When clogging occurs or fluid pressure increases, the element deforms to enlarge the openings or shift position, preventing blockage and facilitating self-cleaning
Solution Approach 2:
The patent changes the physical state and geometric parameters of the jet outlet element by using elastic material that responds to pressure changes. The element transitions between different shapes and opening sizes based on operating conditions, allowing the system to adapt from fine jet mode to anti-clogging mode automatically
2Ease of operation
If the jet outlet element is made of elastic material to enable deformation under fluid pressure, then the self-cleaning capability is improved, but the manufacturing complexity increases
Solution Approach 1:
The jet outlet element is constructed as a flexible component made of elastic material that can be molded into the desired shape with integrated fine jet openings. This flexible membrane approach eliminates the need for complex mechanical moving parts, seals, or actuation mechanisms, achieving self-cleaning through material elasticity alone
Solution Approach 2:
The patent employs elastic material that combines the properties of flexibility and structural integrity. This composite material approach allows the jet outlet element to be manufactured as a single integrated component that兼具 deformability for self-cleaning and durability for reliable operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device operates reliably with minimal maintenance, providing a fine mist-like shower jet that is resistant to clogging, as the deformation of the jet outlet element under fluid pressure prevents dirt and lime accumulation and facilitates automatic removal of incipient clogging.
Implementation Method 1
a jet outlet element (6) which is arranged, with its bottom (6a) facing in the jet outlet direction, in the associated jet disc opening (5) and has in its bottom a plurality of fine jet openings (7) and is composed of an elastic material and is configured to deform by bulging of its bottom (6a) and/or its side wall (6b), in response to a fluid operating pressure present in the hollow chamber (6c)

AI summary
A shower jet outlet device and a shower head equipped therewith have a jet disk with at least one jet disk opening and a jet outlet element disposed in the jet disk opening. The jet outlet element is pot-shaped with an outlet-side bottom, a side wall and a hollow chamber delimited by the bottom and the side wall. The bottom faces in the jet outlet direction and includes fine jet openings. The bottom and the side wall are made of an elastic material and the jet outlet element is configured to deform by bulging of its bottom and/or its side wall, in response to fluid pressure in the hollow chamber when operating.
