One-Touch Detachable Shower Head Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower heads are difficult for women and the elderly with weak wrist power and grasping ability to attach or detach from hoses due to screw-coupling requirements, leading to leaks and increased effort for handling and filter maintenance.
Innovation Solution
A shower head with a one-touch detachable structure featuring a handle body connected to a hose via a male coupler with a cylindrical shape and a female coupler with sealing members, allowing for easy locking and unlocking, and a separate connection mechanism using ball seating parts and a push member for one-touch attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-coupling is used to connect the handle body to the hose, then the connection is firm and reliable, but it requires strong wrist power and multiple rotations to attach or detach, making it difficult for women and the elderly to operate
Solution Approach 1:
The connection mechanism is divided into two independent parts: a male coupler with insertion tube and a female coupler with holder ring and elastic piece. This segmentation allows one part (the elastic piece) to provide automatic locking for reliability while the other part (insertion tube) allows simple push-in operation for ease of use, eliminating the need for rotational screwing.
Solution Approach 2:
The elastic piece automatically locks the insertion tube when pushed in, providing self-locking functionality without requiring user intervention for tightening. The system serves itself by using the elastic deformation of the holder ring to maintain the locked state, ensuring reliable connection while requiring minimal user effort.
2Reliability
If screw-coupling is used to connect the head part to the handle, then the connection is secure, but it requires separation of the handle from the head part to access and clean the filter member, making maintenance difficult for women and the elderly
Solution Approach 1:
The shower head is divided into separable components: the head part with filter member can be independently removed from the handle body through the one-touch connection mechanism. This allows the filter member to be accessed and cleaned without requiring the user to deal with the entire assembly, simplifying maintenance while the connection remains secure during use.
Solution Approach 2:
The one-touch connection mechanism allows the user to independently service the filter member by simply detaching the head part from the handle body through a simple pushing motion. The system enables self-maintenance without requiring technical expertise or special tools, making filter cleaning accessible to users with limited physical strength.
3Reliability
If screw-coupling is used for connections, then the joints are firm, but water leaks occur when the coupling is not firm, and multiple rotations are required which increases the time and effort for operation
Solution Approach 1:
The holder ring with elastic piece is pre-configured to automatically engage with the insertion tube when pushed in. The elastic piece is positioned to flex and lock onto the insertion tube, creating an automatic locking mechanism that ensures firm connection without requiring the user to perform multiple rotational actions, thus reducing the time and effort for attachment while preventing leaks.

AI summary
Provided is a shower head with the one-touch detachable structure, which is installed in a bathroom or on a sink. The shower head allows women or the old and the infirm who have weak wrist power and grasping power to easily connect and disconnect a handle body of the shower head to and from a hose in one-touch since the hose connected to a faucet and the handle body of the shower head in a one-touch detachable manner. Moreover, the shower head allows women or the old and the infirm who have weak wrist power and grasping power to easily connect and disconnect the handle body to and from the head assembly in one-touch since the handle body and the head assembly are connected and disconnected in a one-touch detachable manner.
