Rotatable Shower Mechanism for Multiple Spray Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower assemblies have fixed top spray heads that cannot be adjusted for angle and height, leading to a singular shower mode that fails to meet user preferences, resulting in a poor user experience.
Innovation Solution
A spraying mechanism with a rotatable supporting arm assembly and shower head that allows for multiple positions and adjustable distances between the shower head and the supporting arm, enabling diverse shower modes by rotating the shower head and arm relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the top spray head is arranged fixed, then the structure is simple and stable, but the shower mode is singular and cannot be adjusted according to user requirements
Solution Approach 1:
The patent applies the dynamics principle by making the supporting arm assembly rotatable relative to the water inlet assembly and the shower head rotatable relative to the supporting arm assembly. This transforms the fixed structure into a dynamic, adjustable system that can provide multiple shower modes (e.g., different spray angles and heights) while maintaining structural stability through defined rotation centers and axes.
2Area of stationary object
If the connection position is fixed at the central axis, then the structure is simple, but dead angles are created and shower coverage is limited
Solution Approach 1:
The patent applies asymmetry by allowing the connection position between the supporting arm assembly and shower head to be offset from the central axis of the shower head. This eccentric connection enables the shower head to rotate to various positions, creating a larger effective shower coverage area and eliminating dead angles by allowing water to be directed toward different zones around the user's body.
3Ease of operation
If the shower head is fixed in position, then installation is simple, but user experience is poor due to inability to adjust angle and height
Solution Approach 1:
The patent applies segmentation by dividing the spraying mechanism into three independently rotatable segments: the supporting arm assembly that rotates relative to the water inlet assembly, and the shower head that rotates relative to the supporting arm assembly. This segmentation allows each component to be adjusted independently, providing multiple degrees of freedom for positioning and angling the shower head to suit user preferences while keeping each individual adjustment mechanism relatively simple.

AI summary
The disclosure provides a spraying mechanism and a water outlet device. The spraying mechanism comprises a water inlet assembly provided with a water inlet channel, a supporting arm assembly connected to the water inlet assembly and rotatable in respect to the water inlet assembly, and a first shower head communicated to the water inlet channel through the supporting arm assembly, connected to the supporting arm assembly and rotatable in respect to the supporting arm assembly. There is at least a first distance and a second distance between a projection of a connection position between the first shower head and the supporting arm assembly in respect to a reference plane perpendicular to the central axis of the first shower head and a projection of a central axis of the first shower head in respect to the reference plane, and the first distance is not equal to the second distance.
