Variable-sized finger ring with spring-biased inner component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional variable-sized finger rings lack a combination of improved functionality, excellent aesthetic appearance, and durability to last a lifetime.
Innovation Solution
A variable-sized finger ring design featuring a fixed diameter outer ring component with a moveable inner component elastically biased by a compression spring, allowing for auto-adjustment of the ring size, and optionally incorporating precious metals for durability and hidden gemstone galleries for aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional variable-sized finger ring designs are used, then the ring size can be adjusted, but the functionality, aesthetic appearance, and durability are insufficient
Solution Approach 1:
The patent applies the dynamics principle by incorporating a moveable inner component that can shift between retracted and extended positions along the inner circumference of the ring. This moveable component, biased by a spring element, dynamically adjusts the effective inner diameter of the ring to accommodate different finger sizes while maintaining structural integrity and durability of the fixed outer ring
2Extent of automation
If a moveable inner component with spring element is added, then the ring size can be automatically adjusted, but the device complexity increases
Solution Approach 1:
The patent applies the nesting principle by placing the moveable inner component inside the fixed outer ring component. The moveable inner component is positioned within the inner circumference of the outer ring, allowing it to adjust ring size without adding external complexity. The spring element is contained within or alongside the moveable component, keeping the overall structure compact and aesthetically pleasing
3Adaptability or versatility
If the moveable inner component is positioned along the inner circumference, then the size adjustment range is improved, but the aesthetic appearance may be compromised
Solution Approach 1:
The patent applies the extraction principle by removing the adjustment mechanism from the visible outer surface of the ring. The moveable inner component operates along the inner circumference, extracting the functional elements from the aesthetic exterior. This allows the outer ring to maintain its fixed diameter and visual appeal while the inner component provides the size adjustment functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides smooth, repeatable, and uniformly applied size adjustments within a range of approximately 1.75 US ring sizes, maintaining a desirable appearance and resisting corrosion, ensuring the ring remains functional and aesthetically pleasing over its lifetime.
Implementation Method 1
a compression spring elastically biasing the moveable inner component radially inwardly in relation to the fixed diameter outer ring component
