Solution Overview

Problem

Conventional decorative finger ring sets, such as wedding rings with guards, often suffer from misalignment and discomfort due to mismatched profiles or ornamentation, resulting in an inconvenient and aesthetically unappealing wear experience.

Innovation Solution

A finger ring set comprising a primary ring with engagement elements and a hinged secondary ring that encloses the primary ring, presenting a unified appearance, with optional ornamentation and adjustable orientation, allowing secure and comfortable wear as a single ring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional ring guards are used with wedding rings, then the rings can be worn together, but misalignment of ring profiles and ornamentation occurs causing discomfort and aesthetic issues

Engineering Contradiction:

ImproveAbility to wear ring and guard togetherVSAvoidComfort and alignment when worn

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The secondary ring is designed to nest over the primary ring with a cross-section relief that accommodates the primary ring's profile. This nesting arrangement ensures proper alignment of the rings while allowing them to be worn together comfortably, resolving the misalignment issue of conventional ring guards.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The secondary ring is divided into two portions connected by a hinge, allowing it to open and close around the primary ring. This segmentation enables easy installation and removal while maintaining proper alignment when closed, addressing both the versatility to wear together and the comfort during wear.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If conventional ring guards are used with wedding rings, then the rings can be worn together, but the appearance is not unified due to misalignment

Engineering Contradiction:

ImproveAbility to wear ring and guard togetherVSAvoidUnified appearance of ring set

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The nested configuration of the secondary ring over the primary ring, with the cross-section relief precisely accommodating the primary ring's profile, ensures that the rings are properly aligned when viewed from the side or end, creating a unified appearance.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The cross-section relief is specifically shaped to match the primary ring's profile at the engagement location, ensuring that only the necessary portion of the secondary ring contacts the primary ring. This localized adaptation maintains the unified appearance while allowing the rest of the secondary ring to provide security.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If a hinged secondary ring is used to enclose the primary ring, then proper alignment and unified appearance are achieved, but the device complexity increases

Engineering Contradiction:

ImproveAlignment and comfort when wornVSAvoidStructure of hinged ring set

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The secondary ring is segmented into two portions connected by a simple hinge, which allows the ring to open for installation and close for secure wear. This segmentation provides the necessary functionality for alignment and comfort without introducing excessive complexity, as the hinge is a straightforward mechanical connection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hinge acts as an intermediary element that connects the two portions of the secondary ring, enabling the opening and closing action. This simple intermediary mechanism achieves the desired alignment and comfort benefits without requiring complex systems, as the hinge directly translates user action into the proper ring configuration.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If engagement elements are added to secure the rings together, then the rings remain securely engaged, but the manufacturing complexity increases

Engineering Contradiction:

ImproveSecurity of ring engagementVSAvoidManufacturing of ring set

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The cross-section relief in the secondary ring is designed to nest over the primary ring's profile, creating inherent engagement through the nested configuration. This nesting provides security without requiring additional complex engagement elements, as the nested shapes themselves create the securing mechanism.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The engagement elements are integrated into the existing structure of the secondary ring portions rather than being separate components. This merging of functions allows the ring to secure the primary ring through its normal closing action, eliminating the need for separate manufacturing processes for distinct engagement mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Finger ring sets according to the present disclosure include a primary ring with one or more precious stones and or other ornamentation. A secondary ring may be hinged to engage and enclose the primary ring, the combination of the primary ring and the secondary ring presenting the image of a single ring. The secondary ring may include one or more precious stones and or other ornamentation and may be hinged with either a north-south or an east-west orientation. Portions of the secondary ring may also engage each other or the primary ring to further secure the primary ring.
