Telescoping Ring Attachment with Conical Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring re-sizing methods often compromise the integrity and comfort of jewelry by requiring metal removal or welding, which can weaken the ring band and create discomfort due to pressure points, and are costly.
Innovation Solution
A ring re-sizing attachment featuring a base with telescoping buttons and a conical spring that adjusts the ring size by compressing when worn, eliminating the need for metal removal or welding and maintaining the ring's appearance and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If metal material is removed to reduce ring size, then ring size is reduced, but ring structure integrity is weakened
Solution Approach 1:
The invention divides the ring size adjustment function into two independent parts: the original ring band remains intact and unchanged, while a separate removable attachment component provides the size adjustment mechanism. This segmentation allows the ring band to maintain its structural integrity while the attachment handles the size modification function.
Solution Approach 2:
The attachment acts as an intermediary element between the wearer's finger and the ring band. It includes a base that interfaces with the ring band and buttons that contact the finger, with spring elements providing the adjustment mechanism. This intermediary structure allows size adjustment without modifying the ring band itself.
2Length of stationary object
If metal material is added to enlarge ring band, then ring size is enlarged, but manufacturing cost increases
Solution Approach 1:
The invention separates the ring into the original band and a detachable attachment component. This allows the attachment to be manufactured independently using cost-effective materials and processes, avoiding the need for expensive metalworking operations on the precious metal ring band itself.
Solution Approach 2:
The attachment uses spring elements and telescoping buttons that can be compressed or extended to change the effective inner circumference of the ring. This parameter change mechanism allows size adjustment without adding permanent material to the ring band, reducing manufacturing costs.
3Length of stationary object
If welding beads are used to increase ring size, then ring size is increased, but ring appearance is compromised
Solution Approach 1:
The invention separates the size adjustment function from the ring band itself by using a detachable attachment. This prevents any permanent modifications or visible alterations to the ring band's appearance, as the attachment can be designed to blend with or complement the ring's aesthetic.
Solution Approach 2:
The attachment's base is designed to conform to and copy the curvature and appearance characteristics of the ring band's inner surface. This allows the attachment to integrate visually with the ring while providing the size adjustment function, avoiding the need for visible welding beads or modifications on the exterior.
4Reliability
If metal beads are welded to hold ring in place, then ring stability is improved, but wearer comfort deteriorates
Solution Approach 1:
The invention distributes the holding function across multiple buttons (typically three) spaced around the ring band, rather than concentrating force at single welding points. Each button makes localized contact with the finger, distributing pressure evenly and preventing the discomfort associated with concentrated pressure points from welded beads.
Solution Approach 2:
The spring elements in the attachment provide a dynamic, elastic connection between the buttons and the ring band. This allows the buttons to flex and adapt to the contours of the wearer's finger, maintaining secure hold while accommodating finger movement and shape variations, thereby improving comfort compared to rigid welded connections.
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 solution provides a comfortable and cost-effective way to adjust ring size without compromising the ring's integrity, as it compresses to fit various finger sizes without altering the ring's exterior or interior structure.
Implementation Method 1
A spring, preferably a conical spring, is held within a volume defined by the telescoping buttons. The top coil of the spring is in contact with the first button at the top of the ring re-sizing attachment. The spring is adapted to urge the at least the first button and second button away from the top surface of the base.

AI summary
A ring re-sizing attachment is 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 digital finger below the knuckle. The attachment includes two or more telescoping buttons joined to a base, with a spring, such as a conical spring, urging the buttons away from the base. The spring is compressed and the buttons urged together to increase the space within the band to move the band beyond a knuckle. Once the band is beyond the knuckle, the spring urges the buttons away from the base to tighten the fit of the ring band around the finger.
