Standing Pipe Faucet Assembly Mechanical Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing standing pipe faucet assemblies made from copper pillars are costly due to high copper prices and generate significant waste, and the traditional welding process for connecting the faucet body and outlet pipe results in unappealing marks and inconsistent quality.
Innovation Solution
A modified standing pipe faucet assembly that eliminates welding by using a shaped copper faucet body with a separate body and a slantwise threaded hole, where a bolt pushes a tube to fix the outlet pipe, faucet body, and separate body together, utilizing O-rings for a waterproof seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a solid copper pillar is used to manufacture the faucet body, then the quality of the faucet body is improved, but the material cost increases and waste materials are produced
Solution Approach 1:
The invention divides the faucet body into multiple components: a separate body, a shaped copper piece, and a outlet pipe assembly. This segmentation allows each component to be manufactured separately with optimized material usage, reducing waste compared to manufacturing a complete solid copper pillar.
Solution Approach 2:
The invention employs a nested structure where the shaped copper piece is inserted into the separate body, and the outlet pipe is assembled into the shaped copper piece. This nesting approach allows precise fitting and connection without requiring excessive material, thereby reducing waste while maintaining quality.
2Loss of substance
If the faucet body is made by slightly shaping a copper pipe, then material cost is reduced, but the faucet body does not have enough thickness to place connecting structures
Solution Approach 1:
The invention separates the faucet body into a separate body (providing structural support and thickness) and a shaped copper piece (providing connection features). This segmentation allows the connection structures to be placed on the shaped copper piece rather than requiring the entire faucet body to be thick enough.
Solution Approach 2:
The invention moves the connecting structures from the faucet body to a separate shaped copper piece that is inserted into the separate body. This dimensional reorganization allows connection features to be added without increasing the overall thickness of the faucet body.
3Strength
If the faucet body and outlet pipe are welded together, then the connection is achieved, but unappealing welding marks are created and aesthetic quality decreases
Solution Approach 1:
The invention replaces the welding process with a mechanical assembly system consisting of insertion, threading, and bolting. The outlet pipe is inserted into the shaped copper piece, secured with a bolt through the slantwise threaded hole, eliminating welding marks while maintaining connection strength.
4Strength
If the welding process is used to connect the faucet body and outlet pipe, then connection is achieved, but the welding quality is inconsistent due to dependence on worker techniques
Solution Approach 1:
The invention employs self-aligning features including the lateral hole groove that guides the outlet pipe into proper position, and the slantwise threaded hole that automatically positions the bolt. This self-service mechanism eliminates dependence on worker skill and experience, ensuring consistent connection quality.
Solution Approach 2:
The invention incorporates pre-formed connection features: the lateral hole groove is pre-formed in the separate body to receive the outlet pipe, and the slantwise threaded hole is pre-formed in the shaped copper piece to receive the bolt. These preliminary preparations ensure consistent assembly quality without requiring skilled welding operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the assembly process, eliminates the need for welding, enhances the aesthetic quality, and maintains the overall quality of the faucet assembly while reducing material costs and waste.
Implementation Method 1
A bolt screwed into the slantwise threaded hole will generate a backward push against a tube that is connected to the rear end of an outlet pipe inserted into the separate body's lateral hole groove
Implementation Method 2
The O-rings hermetically engage in the expanding diameter groove section

AI summary
A standing pipe faucet is formed from a faucet body shaped out of a hollow pillar, a separate body with a corresponding hole connecting it to the faucet body, and a slantwise threaded hole connecting water mixing valve to the assembly. A tube connects an outlet pipe through the hole groove. The tube has an outer diameter equal to the inner diameter of hole groove, and a length shorter than that of the hole groove. The tube corresponding to the threaded hole has a slantwise blocking groove. After the tube is inserted into the hole groove, a bolt is screwed in the threaded hole, generating a backward push between the bolt and the threaded hole, which fixes the outlet pipe and faucet body together. After the chamber has a water outlet through the tube, the whole assembly is completely assembled.
