Shower Head Outflow Assembly With Rotor Control and Drip Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower head water suspension structures are complex, aesthetically flawed due to joint lines, require long and costly manufacturing processes, and have inadequate user experience with large pressing strokes and sensitivity to dimensional tolerance for dripping functions.
Innovation Solution
A water outflow control assembly that integrates into the shower head body through a handle hole, featuring a push rod, rotor, and elastic member, allowing for quick opening, flow adjustment, and dripping functions with reduced rotor thickness and compact design, eliminating the need for separate manufacturing of the shower head body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shower head water suspension structure is manufactured separately and then assembled, then the manufacturing flexibility is improved, but the production cycle is extended and cost increases
Solution Approach 1:
The patent integrates the water suspension structure directly into the shower head body through integral molding, eliminating the need for separate manufacturing and assembly of the water suspension structure. This merging of components reduces the production cycle and assembly steps while maintaining manufacturing flexibility through the integral design process.
2Adaptability or versatility
If the shower head body is manufactured separately and covered on the water suspension structure, then the component customization is improved, but joint lines are formed affecting aesthetics and increasing dirt accumulation
Solution Approach 1:
The water suspension structure and shower head body are integrated into a single molded component, eliminating joint lines and seams. This integral design maintains aesthetic appearance while preventing dirt accumulation in gaps, and component customization is achieved through molding variations rather than assembly.
3Reliability
If a relatively large pressing stroke is required to rotate the rotor, then the rotor can be driven reliably, but the user experience deteriorates
Solution Approach 1:
The patent employs an inclined surface on the rotor that converts the axial pressing motion into rotational motion more efficiently. This curved/angled surface design reduces the required pressing stroke while maintaining reliable rotor activation, improving user experience without sacrificing reliability.
4Reliability
If the shower head structure is required not to completely cut off water to avoid damage, then the internal components are protected, but the dripping function requires high dimensional tolerance control
Solution Approach 1:
The patent incorporates a dripping hole with specific dimensions that allows controlled water flow even when the main water outlet is blocked. This porous/opening design enables the dripping function to operate reliably within standard manufacturing tolerances, protecting internal components without requiring ultra-precise dimensional control.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies manufacturing, enhances aesthetics by eliminating joint lines, improves user experience with reduced pressing stroke, and reduces sensitivity to dimensional tolerance for consistent dripping performance.
Implementation Method 1
an elastic member, resisting between the rotor and the other end of the valve cavity; where when the push rod is pressed, the push blocks urge against the tooth blocks at a stop position, so that the rotor moves axially and rotates; and when the push rod is released, the elastic member drives the rotor to reset axially

AI summary
A water outflow control assembly includes a water inlet body, a push rod, a rotor and an elastic member. The water inlet body is provided with a valve cavity. One end of the valve cavity is provided with a push rod hole for sliding of the push rod. The push rod is provided with push blocks. The rotor is provided with tooth blocks extending toward the push rod hole and matching with the push blocks, and a retaining wall with a gap. The retaining wall is in clearance fit with an inner wall of the valve cavity, and rotation of the rotor changes a degree that the retaining wall blocks a water inlet channel. By adopting the shower head with above mentioned assembly, the water outflow control assembly can be installed through a handle hole of a shower head body of a shower head.
