Slidable Chain Links on Elastic Ring for Fine Jewelry Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jewelry items, such as rings and bracelets, require complex processes to adapt to body size changes, and while chain-like designs simplify size adjustments, they often result in significant size variations with the addition or removal of links.
Innovation Solution
A jewelry item featuring an elastic ring-shaped support element with slidably attached chain links, each with a male and female portion, allowing reversible sliding and locking, enabling small size adjustments without the need for skilled assembly or disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If chain links are added or removed to adjust jewelry size, then the jewelry can be adapted to different sizes, but the size change is always significant and cannot accommodate small size variations
Solution Approach 1:
The chain link is divided into multiple individual links (e.g., 3-5 links) within a single chain link structure. Each small link can slide independently along the support element, allowing incremental size adjustments. When multiple small links are extended, they collectively provide fine-grained size control without requiring addition or removal of entire chain links.
Solution Approach 2:
The chain links are designed to be slidable rather than fixed, enabling dynamic adjustment of the jewelry size. The male and female portions allow the links to move relative to each other along the support element, providing continuous size adjustment capability rather than discrete steps.
2Adaptability or versatility
If traditional jewelry is made to adapt to body size, then it can fit the owner, but the adaptation process is complex and requires skilled jewelers
Solution Approach 1:
The jewelry item enables the user to adjust the size themselves without requiring a skilled jeweler. The slidable chain links with male and female portions can be easily moved and locked into position by the user, making the adaptation process simple and self-serviceable.
Solution Approach 2:
The design transforms the static jewelry into a dynamic, adjustable structure where chain links can slide along the support element. This mechanical simplicity allows users to easily extend or compress the jewelry to fit different body parts without complex tools or skills.
3Ease of operation
If chain links are secured with pins to allow rotation, then the links can move with respect to each other, but the structure becomes complex and difficult to assemble or disassemble
Solution Approach 1:
The chain link is segmented into male and female portions that interface with each other. This segmentation allows the link to be divided into functional parts that can easily connect and disconnect, simplifying assembly and disassembly while maintaining mobility.
Solution Approach 2:
Instead of using pins to connect links (traditional approach), the invention inverts the approach by using interlocking male and female portions that slide into each other. This inversion simplifies the connection mechanism, making it easier to assemble and disassemble while maintaining link mobility.

AI summary
A jewelry item is provided to include a ring-shaped spring and a ring-shaped chain. The ring-shaped chain has a plurality of chain links, each of which is slidably attached to the ring-shaped spring. Each chain link has a plate with a first surface facing the spring and a second surface opposite to the first surface. Each chain link further has a seat and a hook opposite to each other. The hook is inserted into a seat of a subsequent chain link so as to lock the chain links to each other while allowing the chain links to reversibly slide from a compressed position to an expanded position with respect to each other.
