Rotatable Bathroom Fitting Socket for In-Place Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection bases for sanitary faucets do not efficiently allow for maintenance or assembly without disrupting the water supply, and lack effective integration of silencer and backflow preventer elements.
Innovation Solution
A connection base with a rotatable upper part that can be locked into a barrier position to disconnect from the water supply, featuring ball caliper mounting surfaces, frusto-conical contact surfaces for fluid control, and integrated silencer and backflow preventer elements, allowing for easy maintenance and assembly without shutting off the water supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upper base section is fixed to the base body, then the structural stability is improved, but maintenance work requires shutting off the water supply
Solution Approach 1:
The upper base section is designed to be rotatable relative to the base body, transforming from a static fixed connection to a dynamic movable connection. This allows the upper base section to be rotated into a shut-off position that disconnects fluid channels from the water supply, enabling maintenance without shutting off the main water supply while maintaining structural stability during normal operation
2Ease of operation
If the upper base section is made rotatable for maintenance access, then maintenance accessibility is improved, but the device complexity increases
Solution Approach 1:
The connection base is segmented into a base body and an upper base section that can be independently rotated. This segmentation allows the upper base section to be accessed separately for maintenance while the base body remains in place, providing maintenance accessibility without requiring complex disassembly mechanisms
Solution Approach 2:
The mounting surface on the upper base section and the corresponding connection surface on the base body are designed with spherical curvature. This spherical interface simplifies the rotatable connection by providing natural alignment and smooth rotation while maintaining a tight seal, reducing the complexity of the rotatable mechanism
3Adaptability or versatility
If spherical mounting surfaces are used for the valve stem, then alignment flexibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The mounting surface on the upper base section and the connection surface on the valve stem are designed with spherical curvature. This spherical interface provides alignment flexibility by allowing the valve stem to be tilted and rotated into vertical alignment, while the spherical geometry itself guides the alignment process, reducing the actual precision requirements compared to flat surfaces
