Two-Handle Faucet Assembly With Isolated Water Flow Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-handle faucets have complex valve core assembly structures, making them difficult to assemble and costly to produce, with high material requirements that compromise environmental safety and stability.
Innovation Solution
A two-handle faucet design featuring a detachable faucet base made of metal and valve core assemblies with plastic seats, where the valve core seats are hermetically connected to the tee connector, allowing for easy assembly and reduced costs by using environmentally friendly materials for the valve core seats and strong metal for the faucet base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve core assembly structure is made complex to ensure hermetic connection to both water supply and tee connector, then sealing performance is improved, but assembly difficulty and production complexity increase
Solution Approach 1:
The valve core assembly is segmented into modular components: the valve core body with integrated sealing features, the tee connector as a separate hermetic component, and the faucet base as an independent assembly unit. This segmentation allows each component to be optimized for its specific function while simplifying the overall assembly process and reducing production complexity.
2Reliability
If high-strength materials are used for the valve body to ensure water safety and environmental protection, then product reliability is improved, but manufacturing cost increases
Solution Approach 1:
Different material qualities are applied to different components based on their specific functional requirements. The valve core body and sealing surfaces use high-strength, food-grade materials to ensure water safety, while the faucet base and external housing use cost-effective materials with sufficient structural strength. This local quality differentiation maintains water safety while reducing overall manufacturing costs.
3Strength
If the faucet base is made of metal material for strength, then structural reliability is improved, but cost increases and assembly complexity increases
Solution Approach 1:
The faucet base is designed as a detachably mounted metal component that can be assembled separately from the main faucet body. This segmentation allows the metal base to provide structural strength where needed while enabling simplified assembly through standardized mounting interfaces, reducing both assembly complexity and manufacturing costs.
4Ease of operation
If the inlet hose is directly connected to the valve body, then assembly is simplified, but material requirements and cost increase to ensure water safety
Solution Approach 1:
The inlet hose connection is mediated through the valve core assembly's integrated connection features rather than direct connection to the valve body. This intermediary connection method allows for simpler assembly while using cost-effective materials, as the hose connects to the modular valve core assembly which already incorporates necessary sealing and connection mechanisms.

AI summary
A two-handle faucet includes a faucet body, a faucet housing, and a faucet base. The faucet body includes two valve core assemblies, a tee connector, a water outlet pipe, and two water inlet pipes. The water inlet pipes are insertedly connected to the faucet base. The water outlet pipe is hermetically connected to the tee connector. The water inlet pipes are connected to the tee connector through the two valve core assemblies. The valve core assemblies are responsible for the passing of water. The faucet base is only used for supporting the faucet, and the water won't pass through the faucet base. The faucet is safe for use and has sufficient strength, so that the product performance is stable and the cost can be reduced.
