Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handshower and showerhead docking systems lack a secure and efficient mechanism for transitioning between a docked and released position, leading to instability and difficulty in secure attachment.
Innovation Solution
A showerhead assembly with a cradle assembly and mounting puck system, utilizing inclined surfaces and O-rings to facilitate secure engagement and repositioning, allowing the handshower to be easily switched between docked and released positions through a combination of engagement features and elastic biasing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional docking mechanism is used, then the handshower can be mounted, but the attachment is unstable and difficult to secure
Solution Approach 1:
The cradle assembly incorporates movable portions that can transition between open and closed positions, allowing dynamic adjustment during the docking process. The spring element provides dynamic biasing force to automatically engage the docking mechanism, transforming a static attachment system into a dynamic one that adapts during operation.
Solution Approach 2:
The cradle assembly is divided into multiple portions (first portion, second portion, third portion) that can move independently relative to each other. This segmentation allows each portion to perform specific functions: the first portion receives the mounting puck, the second portion provides engagement surfaces, and the third portion maintains positioning, collectively achieving stable attachment through coordinated movement of discrete segments.
2Reliability
If a secure docking mechanism is implemented, then attachment reliability improves, but the complexity of the docking system increases
Solution Approach 1:
The cradle assembly serves multiple functions within a single integrated structure: it receives the mounting puck, provides engagement surfaces through inclined surfaces, maintains positioning through the spring element, and enables secure attachment through the interaction of multiple portions. This multi-functionality reduces the need for separate components, achieving secure attachment without proportionally increasing system complexity.
Solution Approach 2:
The spring element automatically biases the cradle assembly to engage the mounting puck without requiring external actuation or complex control mechanisms. The inclined surfaces automatically guide the mounting puck into the correct position during insertion, and the system self-locks through the interaction of engagement features, eliminating the need for additional motors, sensors, or control systems.
3Stability of the object's composition
If the handshower is securely docked, then stability is achieved, but repositioning and removal become difficult
Solution Approach 1:
The docking mechanism operates in distinct periodic phases: insertion phase where the mounting puck is guided by inclined surfaces, engagement phase where the spring element biases the cradle portions together for stable attachment, and removal phase where the mounting puck is extracted and the spring returns the cradle to its initial position. This periodic action allows the system to transition smoothly between stable docking and easy removal states.
Solution Approach 2:
The cradle assembly's movable portions allow the system to dynamically transition between engaged and disengaged states. During docking, the portions move to closed positions for stable attachment; during removal, they return to open positions to clear the mounting puck. This dynamic capability enables the system to maintain stability when docked while remaining easy to reposition.
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 solution provides a stable and secure attachment mechanism, ensuring the handshower remains securely docked when in use and easily removable for repositioning, enhancing user convenience and system reliability.
Implementation Method 1
The first O-ring is provided annularly about a perimeter of the first portion and the second portion to secure the first portion and the second portion relative to one another
Implementation Method 2
Upon insertion of the mounting puck into the cradle assembly, the first inclined surface abuts the first engagement feature to urge the first portion outward into a clearance

AI summary
A showerhead assembly includes a handshower and a docking mechanism. The handshower includes a mounting puck mountably coupled to a rear portion of the handshower. The docking mechanism is configured to receive the handshower. The docking mechanism includes a cradle assembly positioned adjacent the handshower that is configured to receive the mounting puck. The cradle assembly includes a first portion, a second portion, and a first O-ring. The second portion is adjacent the first portion. The second portion includes a face extending along a rear of the first portion. The first O-ring is provided annularly about a perimeter of the first portion and the second portion to secure the first portion and the second portion relative to one another. Upon receiving the mounting puck, the mounting puck urges the first portion into an open position to receive the mounting puck within the cradle assembly.
