Elastic Ornamental Chain With Cage Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ornamental chains, such as those for necklaces or bracelets, lack elasticity, requiring customization and an opening device for fitting, limiting their adaptability and aesthetic appeal.
Innovation Solution
A modular chain design incorporating cage-shaped elements with integrated elastic elements between the lateral and central bodies, allowing for adjustable length and elastic contraction, eliminating the need for opening devices and enabling a snug fit around the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a modular chain with cage-shaped elements is used, then the chain is simple and can be made in various lengths, but it is not elastic and requires an opening device
Solution Approach 1:
The elastic element is nested within the cage-shaped element structure, with the elastic element positioned between the lateral bodies and the central body of adjacent cage-shaped elements. This integration maintains the modular simplicity while adding elasticity functionality.
Solution Approach 2:
The invention changes the physical parameter of the chain by introducing an elastic element that can deform and recover, transforming the chain from a rigid modular structure to an elastic one that can adapt to body contours.
2Device complexity
If the chain is made to size without elasticity, then the structure is simple, but it does not fit tightly and requires customization
Solution Approach 1:
The elastic element introduces dynamic behavior to the chain, allowing it to stretch and contract based on the body it encircles. This enables the chain to adapt to different sizes and body contours without requiring customization.
Solution Approach 2:
The elastic element provides self-adjusting functionality, where the chain automatically fits tightly to the body through its elastic recovery force, eliminating the need for precise size matching or opening devices.
3Ease of operation
If an opening device is added to the chain, then the chain can be put on, but the aesthetic appeal and simplicity are reduced
Solution Approach 1:
The elastic chain can be expanded by pulling the ends apart and will automatically close when released, eliminating the need for opening or closing devices. The elastic recovery force naturally secures the chain in place.
Solution Approach 2:
The elastic element allows the chain length to change dynamically, enabling the chain to be expanded for putting on and contracted for secure fitting, all without additional mechanical components.
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 elastic chain can be easily customized in length and fits securely around the body without opening devices, enhancing both functionality and aesthetics by providing a flexible, adaptable, and aesthetically pleasing solution.
Implementation Method 1
an elastic element interposed between the free ends of the lateral bodies of each cage-shaped element and the central body of the adjacent cage-shaped element, suited to generate an elastic returning action that tends to contract the chain
