Solution Overview

Problem

Wearing multiple rings, such as a wedding ring and an engagement ring, on the same finger is problematic due to rotation issues causing aesthetic misalignment and discomfort from stone rubbing against the finger, and sizing issues due to weight changes leading to loose fits and potential loss.

Innovation Solution

A kit with circular bands and inserts of varying thickness that fit into adjacent rings to secure them together and adjust size, featuring partially curved plates with projections to lock rings in place and prevent rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple rings are worn on the same finger, then aesthetic expression and personal style are improved, but the rings rotate with respect to each other causing misalignment and discomfort

Engineering Contradiction:
Improveability to wear multiple ringsVSAvoidrelative position stability of rings
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent combines multiple rings with a common band structure that integrates them into a single stable unit. The shared band design merges the individual rings physically, preventing relative rotation while maintaining the ability to wear multiple rings for aesthetic expression.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention segments the ring system into modular components (individual rings attached to a common band) that can be independently selected and configured. This segmentation allows users to choose different ring combinations while the common band ensures stable relative positioning.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If ring size is increased to pass over the knuckle, then the ring can be worn on the finger, but the ring becomes loose and may rotate or fall off

Engineering Contradiction:
Improvering inner diameterVSAvoidring retention on finger
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The patent employs a resilient band material that dynamically adapts to finger size changes. The band can expand to accommodate weight changes and compressibility variations, maintaining secure fit and reliable retention while allowing the ring to pass over the knuckle.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the physical parameters of the band by using resilient material with specific elastic properties. This allows the band to temporarily deform during insertion over the knuckle and then maintain a snug fit during wear, balancing ease of insertion with secure retention.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the band is made resilient to accommodate finger compressibility, then the ring fits the compressible area, but the ring may slide or rotate during wear

Engineering Contradiction:
Improvefit to finger contourVSAvoidring position stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

By merging multiple rings into a single integrated unit with a common band, the invention eliminates independent movement and rotation of individual rings. The unified structure maintains stability on the finger while the resilient material continues to accommodate finger compressibility.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A kit having a ring sizer and ring joiner. The kit has a plurality of circular bands that fit into and engage with a plurality of adjacent rings, such as a wedding ring and an engagement ring, to secure the plurality rings together. In addition, the bands are made in different thickness so the bands can also be used to adjust the size of the rings.
