Sanitary Valve Head With Push-Rotate Handle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve tops for sanitary fittings are limited to either press activities or rotary activities, requiring multiple valves for tasks that need both functionalities, such as controlling water output and adjusting flow volume.
Innovation Solution
A valve top design that allows both press activities and rotary use, featuring a handle that can be moved axially and rotated relative to the headpiece, with a locking device and torque transmission mechanism to enable secure and adjustable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a valve head is designed for push-to-press operation only, then it can reliably control switching (shower/shower head), but it cannot perform rotary operation for flow rate adjustment
Solution Approach 1:
The valve head is designed with a handle that can perform both push-to-press and rotary operations. The handle is connected to a control spindle that responds to both axial displacement (push operation) and rotational movement (turn operation), enabling a single valve to perform multiple functions that previously required separate valves.
2Ease of operation
If the handle is made movable relative to the headpiece for push operation, then push-to-press functionality is achieved, but torque transmission for rotary operation becomes difficult
Solution Approach 1:
The handle is designed with dynamic characteristics that allow it to be displaced axially for push operation while also being capable of rotating for torque transmission. The handle's connection to the control spindle accommodates both linear and rotational movements, enabling the same component to serve dual operational purposes.
3Extent of automation
If electromagnetic actuation is used for push-button operation, then automated control is achieved, but reliability decreases due to contact damage during assembly and additional power requirements
Solution Approach 1:
The invention replaces electromagnetic actuation with a purely mechanical push-button operation system. The handle is directly connected to the control spindle through mechanical means, eliminating electromagnetic contacts that are susceptible to damage during assembly and operation. This mechanical system requires no additional power source and maintains high reliability.
4Adaptability or versatility
If multiple valves are used to achieve both push and rotary functionality, then operational versatility is achieved, but device complexity and space requirements increase
Solution Approach 1:
The invention merges the functionality of multiple valves into a single valve head. By integrating both push-to-press and rotary operation capabilities into one valve with a unified handle and control spindle mechanism, the system eliminates the need for separate valves, reducing overall complexity and space requirements while maintaining full operational versatility.
