Spray Head Manoeuverability via Articulated Arm Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water dispensing devices with spray heads for sinks have limited manoeuverability, making it difficult to reach regions far from the device body without altering the water jet's inclination.
Innovation Solution
The device articulates the arm with the spray head to a region spaced apart from the device body, allowing greater movement of the spray head while maintaining a consistent water jet direction through a pivoting dispensing spigot and a valve system that switches between the spigot and arm water passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the spray head is moved away from the device body using only the flexible arm's deformability, then the spray head can reach farther areas, but the water jet inclination is inevitably modified and manoeuverability remains limited
Solution Approach 1:
The device is divided into three main segments: the device body, the rigid arm, and the flexible arm. The rigid arm provides stable support and positioning, while the flexible arm provides fine adjustment capability. This segmentation allows the spray head to reach farther areas through the rigid arm's extension while maintaining manoeuverability through the flexible arm's deformability, without compromising water jet inclination.
Solution Approach 2:
The invention adds a spatial dimension by extending the rigid arm substantially at right angles to the device body, creating a perpendicular extension that increases reach distance without affecting the vertical water jet inclination. This dimensional change allows the spray head to access farther regions while maintaining proper spray orientation.
2Length of moving object
If the flexible arm is used to move the spray head to reach farther regions, then the reach distance increases, but the water jet inclination is modified
Solution Approach 1:
By segmenting the arm into rigid and flexible portions, the invention assigns different functional roles: the rigid arm maintains stable orientation and water jet inclination, while the flexible arm handles positioning adjustments. This segmentation ensures that reach distance can be extended without compromising the stability of water jet inclination.
Solution Approach 2:
Different parts of the arm have different mechanical properties: the rigid arm portion maintains structural stability and fixed orientation, while the flexible arm portion allows controlled deformation for positioning. This local differentiation of mechanical qualities enables extended reach while preserving water jet inclination stability.
3Device complexity
If the arm is articulated closer to the device body, then the structure is more compact, but the manoeuverability and reach distance are limited
Solution Approach 1:
The rigid arm is articulated to extend substantially at right angles to the device body, utilizing a perpendicular spatial dimension to maximize reach distance without increasing the device's footprint. This dimensional arrangement maintains structural compactness while significantly improving manoeuverability and access to distant regions.
Solution Approach 2:
The combination of rigid and flexible arm portions creates a dynamic structure that can adapt its configuration. The rigid arm provides stable extension, while the flexible arm allows dynamic adjustment of the spray head position and orientation, enhancing manoeuverability without compromising structural compactness.
