Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single coupled faucets with metal valve bodies, such as copper, are costly, heavy, and require complex assembly processes, increasing processing and transportation costs due to the need for welding with water outlet pipes.
Innovation Solution
The faucet valve body and water outlet pipe are made of plastic, integrated through injection molding, reducing metal costs and weight, and simplifying the assembly process by eliminating the need for welding, with metal components used only where necessary for added strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal valve body (copper) is used, then strength and durability are improved, but cost and weight increase
Solution Approach 1:
The patent changes the material parameter from metal to plastic, fundamentally altering the density and weight characteristics while maintaining structural integrity through design optimization
Solution Approach 2:
The patent employs composite construction by integrating the valve body and water outlet pipe as a unified plastic component, creating a composite structure that achieves both weight reduction and structural strength
2Strength
If a metal valve body (copper) is used, then strength is improved, but processing complexity and cost increase due to welding requirements
Solution Approach 1:
The patent merges the valve body and water outlet pipe into a single integrated component, eliminating the need for separate assembly operations such as welding and reducing processing complexity
Solution Approach 2:
The patent adopts plastic material that is easier and cheaper to process compared to metal, sacrificing some material prestige but gaining significant advantages in manufacturability and cost-effectiveness
3Reliability
If a metal valve body (copper) is used, then durability is improved, but transportation cost increases due to weight
Solution Approach 1:
The patent changes the material parameter from metal to plastic, fundamentally altering the density and weight characteristics while maintaining structural integrity through design optimization
