Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional rings with solid bands are expensive, uncomfortable, prone to damage, and lack adjustability and unique design features, as they require extensive precious metal, restrict finger movement, and have unattractive seams and fixed decorative elements.

Innovation Solution

A ring design featuring a band with disconnecting ends and a movable tubular link that includes jewelry settings, allowing the link to float on the band and move with finger or hand movements, reducing material usage, eliminating seams, and distributing impact forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If an endless solid band is used to construct the ring, then the ring structure is complete and durable, but the cost increases due to extensive precious metal requirement

Engineering Contradiction:

Improvering structure durabilityVSAvoidprecious metal usage

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The ring band is divided into two separate ends with an opening between them, rather than using a continuous endless band. This segmentation reduces the quantity of precious metal required while maintaining the structural integrity needed for ring durability.

Inventive Principle:

Principle #1Segmentation

2Strength

If an endless solid band is used, then the ring maintains structural integrity, but comfort is reduced due to complete finger contact and poor air transmissibility

Engineering Contradiction:

Improveband structural integrityVSAvoidfinger comfort and air transmissibility

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

By introducing an opening that separates the band into two ends, air can circulate between the band and the finger, improving comfort and transmissibility while the band still maintains sufficient structural integrity to function as a ring.

Inventive Principle:

Principle #1Segmentation

3Stability of the object's composition

If an endless solid band is used, then the ring is secure on the finger, but adjustability is limited and removal becomes difficult

Engineering Contradiction:

Improvering fit stabilityVSAvoidsize adjustment capability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The opening in the band allows the ring to dynamically adjust to finger movements and size variations. The two ends can move relative to each other, enabling easier removal and accommodation of different finger sizes while maintaining stability when worn.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If the band is manufactured by bending a narrow strip of precious metal into a spiral, then the band can be formed, but unattractive seams appear on both inside and outside of the ring

Engineering Contradiction:

Improveband formation processVSAvoidseam appearance

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The opening removes the problematic seam formation area from the ring structure. By not joining the band ends together, the manufacturing process avoids creating visible seams on both the inside and outside of the ring, eliminating the aesthetic defect while still allowing the band to be formed from metal strips.

Inventive Principle:

Principle #2Taking out (Extraction)

5Strength

If an endless solid band is used, then the ring is structurally sound, but it is prone to damage at jewelry setting areas when impact occurs

Engineering Contradiction:

Improveband structural soundnessVSAvoidimpact damage to decorative elements

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The opening in the band creates a structural break that can absorb and distribute impact forces away from the vulnerable jewelry setting areas. When the ring is dropped or subjected to impact, the opening allows the band to flex and dissipate energy, protecting the decorative elements from disintegration.

Inventive Principle:

Principle #1Segmentation

6Stability of the object's composition

If decorative elements are fixed to one location on the band, then the setting is secure, but the design becomes dull with limited reflection and viewing angles

Engineering Contradiction:

Improvedecorative element positioningVSAvoiddesign appeal and viewing angles

Core Design Contradiction:

Stability of the object's compositionVSShape

Solution Approach 1:

The opening in the band allows decorative elements to be positioned at the ends rather than fixed in a single central location. This dynamic positioning enables multiple reflection angles and viewing perspectives as the ring moves on the finger, enhancing design appeal while the ends provide secure anchoring points for the decorative elements.

Inventive Principle:

Principle #15Dynamics

AI summary

Innovative jewelry articles are contemplated. The jewelry articles include a band and a link that is movable with respect to the band based on hand or finger movement. The band includes two disconnecting ends with a through hole provided at each end. The link includes two prongs with each inserted through the corresponding hole to connect the two ends. The link also includes two jewelry settings with each connected to the respective prong inserted through the hole. The settings on the band keeps the link hanging on the band. The link further includes a body that extends toward the center of the band. The body contacts the finger when the jewelry article is worn. With this contact, finger or hand movement can cause the tubular link to move up and down with respect to the band.
