Ring Re-sizing Attachment With Spring-Loaded Button
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring re-sizing mechanisms often compromise the integrity and comfort of jewelry rings by requiring metal removal or welding, which can weaken the ring structure and cause discomfort due to pressure points, and are costly.
Innovation Solution
A ring re-sizing attachment featuring a base with a leaf spring and button mechanism that slides within the base's inner cavity, using support ribs and curved tip ends for smooth operation and distribution of force, allowing for adjustable ring size without altering the ring's exterior or weakening its structure, and is affixed to the ring band using adhesive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metal material is removed or welding is performed to resize the ring band, then the ring size can be adjusted, but the ring structure is weakened and integrity is compromised
Solution Approach 1:
The ring resizing function is segmented into a separate attachment device rather than modifying the ring band itself. The attachment includes a base affixed to the ring band and a movable button that can be positioned to create gaps in the ring circumference, allowing size adjustment without altering the original ring structure.
Solution Approach 2:
An intermediary attachment device is introduced between the ring band and the wearer's finger. This attachment includes a base affixed to the ring band and a movable button mechanism that creates adjustable gaps, serving as a mediator that enables size adjustment without directly modifying the ring band's integrity.
2Reliability
If metal beads are welded into the ring band to hold the ring in place, then the ring can be secured on the finger, but pressure points are created causing discomfort
Solution Approach 1:
The mechanical system of welded metal beads creating pressure points is replaced with a spring-loaded button mechanism. The spring applies distributed contact pressure through the button surface area, substituting the concentrated pressure of welded beads with a more comfortable distributed pressure system that maintains ring security without causing discomfort.
3Adaptability or versatility
If the ring band is stretched or cut down to reduce size, then the ring fits a smaller finger, but the ring band is weakened and imperfections are introduced
Solution Approach 1:
The ring band is prepared with a preliminary attachment device that includes a base affixed to the band and a movable button mechanism. This preliminary setup allows the ring size to be adjusted by repositioning the button to create gaps, eliminating the need for subsequent cutting or stretching operations that would compromise the ring band's quality.
4Adaptability or versatility
If a spring wire is inserted into a groove in the ring band to re-size the ring, then the ring size can be adjusted, but the ring band must be modified with grooves which weakens the structure
Solution Approach 1:
The spring wire and groove mechanism is extracted from the ring band structure. Instead of modifying the band with grooves to receive a spring wire, the invention uses a self-contained attachment device with a base affixed to the band and an integrated spring-loaded button mechanism, eliminating the need to compromise the band's integrity for structural modifications.
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
This solution provides a comfortable, cost-effective, and non-invasive method to adjust ring size without compromising the ring's integrity or appearance, ensuring long-term usability and comfort for wearers.
Implementation Method 1
A leaf spring is arranged in the inner cavity of the base. The leaf spring has an arcuately curved top surface and a bottom surface opposite the arcuately curved top surface. The leaf spring has a first tip end that contacts the button and a second tip end that contacts the button. A bottom cover extends over at least the inner cavity of the base to retain the leaf spring in the inner cavity of the base. The leaf spring urges the button away from the bottom cover so that a portion of the button projects above the raised wall of the base.

AI summary
One or more ring re-sizing attachments are appended to the internal circumference of a ring band so that a ring band large enough to pass over a knuckle remains comfortably fit around the finger below the knuckle. Each attachment includes a base defining an internal volume surrounded by a raised wall. A button slidingly engaged in the base internal volume defines an inner volume, and one or more springs are held in the button inner volume. As the one or more springs are compressed, the button moves into the internal volume of the base, increasing the space within the band to move the band beyond a knuckle. Once the band is beyond the knuckle, the spring(s) urge the button upwardly, causing the lips of the button to contact ledges or lips projecting from the sidewall of the base, to tighten the fit of the ring band around the finger.
