S-Connector Extended Leg for Pipe Fitting Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing S-connectors for connecting water pipes to fittings face challenges in precise adjustment and installation, leading to visual and functional defects due to the limitations of tap extensions, which require significant assembly effort and often result in leaks and consequential damage.
Innovation Solution
An S-connector with a 1/2" male thread of at least 30 mm length, allowing direct screwing into the wall disk and adjustable to exact size, eliminating the need for tap extensions, ensuring precise positioning of the 3/4" external thread for a secure and visually appealing fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tap extensions are used to bridge the distance between the wall plate and the S-connection, then the distance can be adjusted, but the assembly effort increases significantly and precise positioning becomes difficult
Solution Approach 1:
The invention extracts the distance adjustment function from separate tap extensions and integrates it directly into the S-connection body. The S-connection is provided with an extended leg that protrudes from the wall, allowing the distance to be adjusted by selecting different leg lengths rather than assembling multiple separate components.
Solution Approach 2:
The invention merges the wall plate connection function and the distance extension function into a single integrated S-connection component. The extended leg is formed as an integral part of the S-connection, combining what were previously separate elements (wall plate, tap extensions, and S-connection) into one unified component.
2Length of stationary object
If tap extensions are used to achieve precise positioning, then the distance can be bridged, but visual defects occur due to exposed threads and the fitting cannot be properly sealed
Solution Approach 1:
The invention performs the positioning action in advance by providing the extended leg with a predetermined length that protrudes exactly the required distance from the wall. This preliminary positioning ensures that the fitting can be correctly installed and sealed without requiring additional adjustment or resulting in exposed threads.
3Length of stationary object
If multiple tap extensions are combined to bridge larger distances, then the reach is increased, but the assembly time increases to two hours or more and leakage risks increase
Solution Approach 1:
The invention extracts the multi-component assembly requirement and replaces it with a single integrated extended leg component. This eliminates the need to assemble multiple tap extensions with different sealing requirements, reducing assembly time from two hours or more to a single straightforward installation.
4Ease of operation
If the 3/4" external thread protrudes too far from the wall, then it can be easily accessed, but it cannot be completely covered by the rosette creating a visual defect
Solution Approach 1:
The invention changes the parameter of thread protrusion distance to an optimal value through the extended leg design. The leg length is specifically dimensioned to provide sufficient thread accessibility for fitting installation while ensuring that the thread protrudes exactly the right amount to be completely covered by the rosette, eliminating visual defects.
