Zinc Alloy Faucet Body With Separate Copper Shaft Seat Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kitchen faucets made of copper alloy materials are costly due to the need for high-strength, water-resistant materials, which increases production costs.
Innovation Solution
A mounting structure for a faucet body and shaft where the shaft seat assembly is separate from the faucet body, allowing the faucet body to be made of zinc alloy, reducing material costs while maintaining strength and safety by using a plastic washer to prevent electrochemical corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the faucet body is made of copper alloy material to ensure water safety and strength, then the strength and water resistance are improved, but the material cost increases
Solution Approach 1:
The invention divides the faucet body into two separate components: a zinc alloy body and a copper shaft seat assembly. The zinc alloy body provides structural strength and supports the overall weight, while the copper shaft seat assembly contacts water and provides water safety. This segmentation allows each component to be optimized for its specific function, reducing the need for expensive copper throughout the entire faucet body.
Solution Approach 2:
The invention applies different material qualities to different parts of the faucet based on their specific requirements. The zinc alloy body uses high-strength material for structural support where water contact is not required, while the copper shaft seat assembly uses water-safe material only where water contact occurs. This local quality approach optimizes material usage and reduces overall cost.
2Device complexity
If the shaft seat is integrally formed with the faucet body to simplify structure, then the device complexity is reduced, but the material cost increases due to water contact requirements
Solution Approach 1:
The shaft seat is separated from the faucet body as an independent assembly that can be manufactured separately and then installed into the zinc alloy body. This segmentation allows the shaft seat to be made of copper for water safety while the body remains zinc alloy for cost efficiency, without requiring complex integrated manufacturing processes.
Solution Approach 2:
The invention introduces a mounting structure with mounting passages and mounting holes as an intermediary connection mechanism between the zinc alloy body and the copper shaft seat assembly. This intermediary structure facilitates the assembly of different materials while maintaining structural integrity and water safety, without requiring direct integration of the shaft seat into the body.
3Ease of manufacture
If the faucet body is made of zinc alloy to reduce cost, then the material cost is reduced, but the water safety and corrosion resistance deteriorate
Solution Approach 1:
The invention segments the water-contacting portions from the non-water-contacting portions of the faucet. The zinc alloy body serves as the structural framework that does not contact water, while the copper shaft seat assembly is specifically designed to contact water. This segmentation ensures that water safety requirements are met at the water interface while allowing cost-effective zinc alloy usage for the main body.
Solution Approach 2:
The invention applies water-safe copper material locally at the shaft seat assembly where water contact occurs, while using cost-effective zinc alloy for the body portions where water contact is prevented through proper design. This local quality approach ensures water safety is maintained at critical interfaces without requiring expensive materials throughout the entire faucet.
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
The solution reduces the material cost of the faucet body while ensuring water quality and strength, as the zinc alloy faucet body is not in contact with water, and the separate shaft seat assembly can be made of copper or plastic to prevent corrosion.

AI summary
A mounting structure for a faucet body and a shaft includes a faucet body made of a zinc alloy material, a shaft seat assembly, a shaft and a press cover. The faucet body has a vertical passage and a mounting passage. The shaft seat assembly is disposed separately from the faucet body. The shaft seat assembly includes a shaft seat located in the vertical passage and a sleeve located in the mounting passage. The shaft is inserted in the sleeve and located between the press cover and the shaft seat. The mounting structure can reduce the material cost of the faucet body and ensure the water quality and the strength of the faucet body.
