Plastic-Metal Composite Connection Body for Faucets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection bodies for flush-mounted installation bodies in sanitary faucets are costly due to the use of brass, which does not efficiently balance manufacturing costs with strength requirements.
Innovation Solution
A connection body with a base body partially made of plastic and at least one connection for a fluid line partially made of metal, where the metal connection is cast into the plastic base body, reducing material usage and costs while maintaining strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the connection body is made entirely of brass to satisfy strength requirements, then the strength is sufficient, but the manufacturing cost increases
Solution Approach 1:
The connection body combines plastic and metal materials to create a composite structure. The plastic base body provides the main structure while metal insertions provide localized strength at connection points, achieving required strength without using expensive brass throughout the entire component.
Solution Approach 2:
Instead of making the entire connection body from strong but expensive brass, metal insertions are placed only at specific locations where strength is required (connection points). The rest of the body uses cheaper plastic material, optimizing the balance between strength and cost.
2Ease of manufacture
If the connection body is made entirely of plastic to reduce manufacturing cost, then the manufacturing cost decreases, but the strength of connections becomes insufficient
Solution Approach 1:
The connection body combines plastic and metal materials to create a composite structure. The plastic base body provides the main structure while metal insertions provide localized strength at connection points, achieving required strength without using expensive brass throughout the entire component.
Solution Approach 2:
Instead of making the entire connection body from strong but expensive brass, metal insertions are placed only at specific locations where strength is required (connection points). The rest of the body uses cheaper plastic material, optimizing the balance between strength and cost.
3Ease of manufacture
If metal connections are cast into the plastic base body, then the manufacturing cost is reduced, but the manufacturing process complexity increases
Solution Approach 1:
The metal insertions and plastic base body are combined in a single casting process. The metal inserts are placed in the mold cavity and then plastic is injected around them, creating an integrated component that combines both materials in one manufacturing step.
Solution Approach 2:
The mold cavity acts as an intermediary that facilitates the combination of metal and plastic materials. By using the mold to hold metal inserts and inject plastic around them, the complex task of combining two different materials is simplified into a single integrated process.
