Anatomically Correct Ring with Multi-Zone Internal Diameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jewelry rings often suffer from a mismatch between the internal diameter needed to clear the knuckle and the diameter required for a comfortable fit on the finger or toe, leading to oversizing and rolling issues, with existing solutions being costly and time-consuming to customize.
Innovation Solution
An anatomically correct ring design with an internal surface featuring inwardly projecting structures and recessed surfaces that mirror the shape of the knuckle, allowing the ring to fit comfortably over the knuckle while maintaining a smaller diameter for the ring bearing portion, along with specialized sizing tools for accurate measurement.

Engineering Contradiction Analysis
1Length of moving object
If the internal ring bearing diameter is increased to clear the knuckle, then the ring can be placed on the appendage, but the ring becomes oversized for the ring wearing portion and tends to roll
Solution Approach 1:
The ring's internal surface is segmented into multiple zones with different diameters: a first internal diameter at the knuckle-clearing portion and a second internal diameter at the ring bearing portion. This segmentation allows each zone to serve its specific function - the larger first diameter clears the knuckle while the smaller second diameter provides stable fit on the finger
Solution Approach 2:
Different portions of the ring's internal surface are given different dimensional properties. The knuckle portion has a larger internal diameter optimized for clearing the knuckle, while the bearing portion has a smaller internal diameter optimized for stable fit. Each local region has quality tailored to its specific functional requirement
2Ease of manufacture
If conventional circular ring design is used, then manufacturing is simple, but the ring does not fit the anatomical shape of the knuckle and appendage
Solution Approach 1:
The ring transitions from a symmetric circular cross-section to an asymmetric design where the internal surface has different diameters at different locations. The internal surface profile is asymmetric relative to the external circular shape, allowing the ring to conform to the asymmetric anatomy of fingers and knuckles while maintaining simple external manufacturing
3Reliability
If custom solutions like sizing beads or springs are added to reduce ring rolling, then ring stability improves, but manufacturing complexity and cost increase
Solution Approach 1:
The solution extracts the rolling prevention function from separate add-on components (beads, springs, hinges) and integrates it directly into the ring's basic structure through the multi-diameter internal surface design. The anti-rolling capability is built into the fundamental geometry rather than added as a separate mechanism
Solution Approach 2:
The ring's multi-diameter internal surface automatically provides rolling prevention through its geometric design alone, without requiring additional active components or mechanisms. The structure serves its own stabilization function through its inherent shape

AI summary
A method of manufacturing, tool for manufacturing and an improved ring design and configuration having an improved anatomically correct internal shank with an internal surface having a plurality of spaced apart inwardly projecting internal structures and recessed surfaces configured for enabling the ring to pass over the knuckle at a reduced ring diameter, and having an internal portion of the ring transformed from the standard and long traditional circular shape to one that compliments the shape of the knuckle over which the ring traverses, and having a narrower diameter when placed on the ring bearing back portion of an appendage of a wearer providing an improved fit and comfort of the ring during use by the wearer.
