Solution Overview

Problem

Conventional rings face issues with sizing incompatibility, discomfort due to physiological changes, and difficulty in adjusting inner diameter, leading to aesthetic and functional problems, especially with embedded stones, and existing solutions complicate assembly and increase volume.

Innovation Solution

An ornamental ring with an elastic annular element interposed between the crown and adjusting elements, allowing the inner diameter to adjust with finger size changes, featuring a rapid assembly process and reduced volume, using a traction spring and pin locking mechanism for easy size adaptation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the crown element has a fixed inner diameter, then the manufacturing process is simple, but the ring cannot adapt to finger size changes

Engineering Contradiction:

Improveadaptability to finger sizeVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The crown element is divided into multiple adjustable segments or components that can move relative to each other, allowing the inner diameter to be adjusted to fit different finger sizes while maintaining a relatively simple overall structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The crown element incorporates dynamic components such as elastic elements that allow the structure to automatically adjust and adapt to finger size changes, transforming a static structure into a dynamic one that responds to physiological variations

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If goldsmith operations are used to change inner diameter, then the ring size can be adjusted, but the aesthetics and visual effect are compromised

Engineering Contradiction:

Improvesize adjustabilityVSAvoidaesthetic integrity

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The adjustment mechanism is segmented into discrete components that can be configured to maintain the continuous surface and decorative patterns of the crown element, avoiding the need for goldsmith operations that would compromise aesthetics

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An intermediary adjustment mechanism is introduced that operates independently of the decorative surface, allowing size changes without affecting the aesthetic integrity of embedded stones or engravings

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple components are used for diameter adjustment, then the inner diameter can be varied, but the assembly process becomes long and difficult

Engineering Contradiction:

Improvediameter variabilityVSAvoidassembly speed

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Multiple adjustment components are merged into an integrated mechanism that operates as a unified system, reducing the number of separate assembly steps and simplifying the overall assembly process while maintaining diameter variability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The adjustment mechanism is pre-configured or pre-assembled in a compact form that allows for rapid installation and quick size adjustments, eliminating the need for complex on-site assembly operations

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If multiple components are used for diameter adjustment, then the inner diameter can be varied, but the ring volume increases

Engineering Contradiction:

Improvediameter variabilityVSAvoidcrown element volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Adjustment components are nested within the existing crown element structure or positioned in a space-efficient manner, allowing diameter variability without significantly increasing the overall volume of the ring

Inventive Principle:

Principle #7Nested doll (Nesting)
