Pop-Up Wash-Basin Valve With Removable Sink Trap Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pop-up valves for wash-basins are difficult to service and clean due to their design, requiring operation underneath the basin and complicating the removal of the water trap for maintenance.
Innovation Solution
A pop-up valve system where the water trap is detachably connected to the valve plate, allowing it to be lifted through the valve opening, with axial fixation via a detachable joint, facilitating easy dismounting and cleaning without affecting the valve's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pop-up valve is fitted with an abutment on the wash-basin underside, then the valve can be operated conveniently, but the valve body and water trap become difficult to remove for repair and cleaning
Solution Approach 1:
The device is divided into separable components: the valve body can be detached from the wash-basin, and the water trap can be removed independently. This segmentation allows convenient operation when assembled while enabling easy removal for repair and cleaning when disassembled.
Solution Approach 2:
The connection between components transitions from static (permanent fixation) to dynamic (detachable connection). The valve body and water trap are connected through removable joints that allow them to be assembled for operation and disassembled for maintenance, providing operational flexibility.
2Stability of the object's composition
If the water trap is fixed permanently in position, then it provides stable support for the pop-up mechanism, but it becomes difficult to remove for cleaning
Solution Approach 1:
The water trap connection transitions from permanent to detachable. Lock members provide stable fixation during operation, but can be released to allow easy removal of the water trap for cleaning, enabling dynamic adjustment between stability and maintainability.
Solution Approach 2:
Lock members act as intermediary elements between the water trap and the valve body/casing. These lock members provide stable connection during operation but can be disengaged to facilitate easy removal, serving as a mediator that enables both stability and ease of maintenance.
3Reliability
If the valve plate is connected permanently to the water trap, then the pop-up mechanism functions reliably, but the entire assembly becomes difficult to dismount
Solution Approach 1:
The valve assembly is segmented into the valve plate and the water trap, connected by a detachable connecting device. This allows the components to function reliably when connected while enabling easy separation for maintenance or replacement of individual parts.
Solution Approach 2:
The connection between the valve plate and water trap is dynamic rather than static. The detachable connecting device allows the assembly to be connected for reliable operation and disconnected for easy dismounting and maintenance of individual components.

AI summary
The invention concerns a device at a wash-basin and comprises a water trap (2) and a basin valve (1). The valve is of the pop-up type. This means that the valve plate (101) is displaced from the closed to the open position and vice versa by a compressive force of the hand on its upper side. According to the invention, the water trap has an outer dimension that allows its passage through the valve opening. The valve plate (101) is turnable and, in a first turning position, liftable from the wash-basin. The valve plate (101) is coupled to the water trap (2) by a connecting device that connects the water trap (2) with the valve plate (101) so that the water trap (2) follows the valve plate (101) when it is lifted up from the wash-basin. The water trap (2) has lock members (215) for detachable axial fixation of the water trap (2).
