Composite Ornamental Chain Structure for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ornamental chains made of metal materials, such as aluminum, are heavier than desired while aiming to provide both aesthetic and structural properties.
Innovation Solution
A process involving a tubular polymer core enclosed within a tubular metal casing is used to create an ornamental chain, reducing weight by up to 70% compared to aluminum chains of the same volume, while maintaining structural integrity and aesthetic appeal through steps like extrusion, straightening, drawing, firing, and polishing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ornamental chains are made of metal materials such as aluminum to provide structural properties and aesthetic value, then strength and aesthetic properties are improved, but weight increases
Solution Approach 1:
The patent applies composite materials by combining a polymer core with a metal casing to create a hybrid structure. The polymer core provides lightweight properties while the metal casing provides structural strength and aesthetic appearance, resolving the contradiction between weight reduction and maintaining structural properties
Solution Approach 2:
The patent applies local quality by distributing different material properties to different parts of the chain structure. The inner polymer core provides lightweight properties where mass reduction is critical, while the outer metal casing provides strength and aesthetics where these properties are needed, optimizing the overall performance
2Weight of moving object
If ornamental chains are made of polymer materials to reduce weight, then weight is reduced, but structural strength and aesthetic properties deteriorate
Solution Approach 1:
The patent uses composite materials to overcome the limitations of pure polymer materials. The polymer core provides weight reduction while the metal casing restores structural strength and aesthetic properties, achieving a balance that neither material could provide alone
Solution Approach 2:
The patent applies the nesting principle by placing the polymer core inside the metal casing, creating a layered structure where each material contributes its advantageous properties. This nested configuration allows the lightweight polymer to be protected and supported by the stronger metal outer layer
